Cockshutt 70 tractor (1935-48)

[frizzen]

Well my Ford 7710 project is still only a 'ruined toy' needing front end parts that i'm poorly equipped to fabricate. I figured i should restart with an easier tractor, and come back to it later. I needed a Narrow Front or something that already had articulating steering, so i stumbled across these.

https://i.imgur.com/5seP8d4h.jpg

Without knowing anything about either of them, the one on your Left looked like a great basis to start with. Soft rubbery tires, enclosed hood instead of engine detail, Narrow Front wheels, says cock, little wing steps above rear axle, pretty cool looking lines.

Plan right now: pair of 200 rpm 12v gearmotors, a mg90s servo, 10a esc, 2ch radio, some 2/3A nimh cells. Punch couple holes for switches, charge port, and antenna 'exhaust pipe'.

I'm only planning to use it to pull stuff with the drawbar. I don't think it's worth setting up a 3-pt hitch, or trying to make the mid-mount cultivator things.

It's not an Ertl, but it is still 1/16 scale diecast metal just like their tractors.

Once i figured out this much, I've been doing some research on it, and the Cockshutt 70 is a Row-crop tractor built from 1935-48. Seems like they were built by Oliver, and sold in Canada. Hart Parr 70 / Oliver 70 / Cockshutt 70.
--
This machine seems to have been made by 'Spec Cast' and apparently lost its rear fenders somewhere along the way.

{Nope. Made by 'Scale Models' out of Iowa, by an Ertl after they sold the name}

I also ran across a place that sells toy tractor & equipment parts in 1/16 scale.

I'm seeing some stuff that would help my 7710, the Barber-Greene loader, and all kinds of stuff that would look great on pallets for my forklift.

This one only had 2 rivets securing body halves.

Chop off axle tubes, make gearmotor holes, glue motors under the wings, backfill some glue from inside chassis. I could have narrowed the rear track closer to stock, but thought it'd play in well with the endless debate about Tricycle vs Wide tractor stability. They were scared and put wideners on it.

Chop down the front axle steering tab, glue a vertical tube to steering, make an ugly linkage.

50 years ago when I was a farm kid, one of our neighbors was fond of Cockshuts and Minneapolis Molines. I don't remember them having a 3 point hitch, just the drawbar. Hydraulics were still a "new" thing in the time when this tractor was built.

Does it have the belt drive pulley on it for running stationary equipment? That was pretty standard equipment on a tractor up until the 60's.

Don

[frizzen]

Thank you, i'm interested in whatever you might remember from these.
I knew that in this time it seemed like nearly every brand had to have their own attachment method. I'm just a suburb kid that was at least in 4-H. Help point me in the right direction.

This one does not have the flatbelt Drive wheel on the side, but i'm seeing that some of these model 70s were equipped with them. It's a 6 spoked wheel. Once i can play with component layout inside, i might have to see if there's room for like an N20 gearmotor and switch to run one.

It looks like the 70 came in: Row Crop, Standard, Orchard, and Industrial.
Row Crop, narrow front
Standard
Orchard, had wide front, lower, and fairings to lift branches over tractor
Industrial

[ddmckee54]

We're recovering from storm damage around here and this is the third time I've typed this, lost it before I could get it posted both of the other times.

The narrow front end was what my Dad preferred for a tractor. He thought it did less damage to the crops as you turned around at the end of the rows. He was the one buying the equipment so who was I to argue? We didn't buy our first "big" tractor with a wide front end until '72.

[frizzen]

That sucks, hope your area gets squared away quickly from that!

I knew that narrow would fit between a row, and is more maneuverable for trailers and stuff. I hadn't considered damage at the ends of the field.

I'm testing out if JBweld will be enough to hold the steering linkage tube to pedestal, or if i'll need to redesign my plan a little and fire up the Mig.

[jerry56]

You know what I've thought about trying is the panel adhesive they use for the new Ford aluminum body panels, if it can stand up to body flex I would think it would be strong enough for an RC truck...maybe...

[ddmckee54]

JBWeld will have plenty of strength for that.

Just be sure to roughen things up a bit to give it a little tooth to grab onto, and be sure you de-grease things before you try gluing them together.

Don

[frizzen]

The gearmotor axles were first superglued (CA) to the little wing bottom, then i filled around the back side with e6000 (shoegoo / amazing goop). Should be strong enough, but shouldn't be awful to replace.

My first steering setup using (end of the tube) Jb Weld didn't hold, but CA seems to be working. Probably going to beef it up with some CA & baking powder paste. Servo is bonded to chassis side with e6000.

The 12v 200rpm motors wired Parallel and running on 7.2v really winds out faster than i'd like for a tractor without ROPS, so i'm going to try them in Series. (it does drive pretty well with everything ziptied to outside.)

--
Uh, apparently i can't read and i bought "2/3AA nimh" cells instead of the "2/3A nimh" cells i'd searched for.
And my soldering iron died.

[ddmckee54]

You can always use the trick that RC Tractor Guy on YouTube uses for some of his 1:32 scale RC tractor builds. Stash a larger battery pack for the tractor in the implement the tractor is towing. The power connection looks like hydraulic hoses to the implement, and you've usually got room in the implement to hide a much larger battery pack.

[frizzen]

Yeah, so when i mentioned it was little too quick i had frankenstein-ed it together for the test run.

https://imgur.com/34mDq2Ch.jpg
But it worked.

So i punched the rest of holes in the bottom for a Charge/Run switch, a female JST charge port, and ESC switch.

https://i.imgur.com/SyS80gMh.jpg

I'm going to be keeping almost everything mounted over in the Left side of tractor because the front wheel locating bosses were on that side. This way to open it: roll to left, pull the 2 screws (that were originally rivets), lift right half up, undo 2 connectors and the halves seperate.

Ordering the wrong cells probably was a good thing, i was able to build up a 5 cell pack that fits in the other half of hood without much trimming. It's only like 650 mAh instead of 1500mAh i wanted, but not like i'm racing.

Mounted a pilot light to the dash, it just plugs into an RX open channel.

I had considered trailering the battery, but really wanted to be able to change equipment, all i have right now is a 4-gang disk. Plus like you said, there wasn't much using Hydro back then.

[jerry56]

On your charge run switch, did you just used a 2 position switch (on/off) as a charge/run where "charge" goes to the battery and charge jack and "run" goes from the battery to the ESC switch then still use the ESC switch as an on/off...

You knew I would ask...lol

[frizzen]

I knew, but i thought you'd find this before i got it all tested out and tried to get decent enough pics to answer your thread. Yep I just used a 3 pin, 2 pos switch. You've got it on my wiring.

Right leg to jst Charge +
Center leg to Battery +
Left leg to Esc +
Then i just spliced the Charge, Battery, and Esc negative wires together.

Since it's mounted on bottom of vehicle it follows the convention of Aft is On. If switch gets bumped on something while moving forward, it still runs. (Any other mounting orientation that's not on bottom, i would use 'Up' or F'orward' for ON.)

My layout is Esc switch by Nose wheel, aft is on (marked '1' / '0' )
Charge port is between switches, closer to charge switch
Charge switch is furthest aft. Aft is Run, and closer to Charge port to charge. (Marked 'R' / 'C' )

-
Then i also learned that tfe2x heatshrink that i *WAS* going to insulate it with doesn't soften until hotter than the melt temp of wiring insulation, cell wraps, and glue holding cells in the battery pack i was building together. So it did the right thing and smoked off 2 cells. Great...

[jerry56]

I don't feel so bad about melting the back bumper on my truck now...LOL

[frizzen]

Heheh.
Oh yeah, mistakes and accidents just go along with not building a Kit. There are no directions to follow, and the materials may not always play nicely together. Makes it interesting and keeps you on your toes.

I'm not like Bob Ross was where i don't make mistakes, but sometimes i can get a "Happy Accident".

[frizzen]

I think we're realistically about 95% done now.

Drill & mount an exhaust stack for the antenna. A bent tip or tractor flap would be the normal way to top that off, so maybe stick a Coke can on top.

Paint the axle tubes, change seat color. Cream grille and lower stripe. Maybe *very light* weathering?

Figure out who wants to be the operator, make them a seatbelt.

Buy & make awesome impliments!!!

[jerry56]

I like the "on" light....since everything is concealed...probably wouldn't have thought of that.

[frizzen]

Who wants to ride my Cocksh
https://imgur.com/pixx2Kxh.jpg
Oh, that was quick.

A Disk Harrow is the only implement i've got, so far. Why don't you go take it over to the field.
https://imgur.com/qfkw9Oih.jpg

https://imgur.com/wecekX6h.jpg

[frizzen]

I've been getting this a bit more squared away and putting some run time on it.

I do not have room to run a Drive wheel for Flatbelt power equipment.
I also do not have room to run a rear PTO.

My exhaust stack is coming up vertical through the hood, will have a bit of a muffler bulge. What way do you guys think would look best to top the stack: Open, a Can upside down, or tractor Flap?

[jerry56]

the can would be classic LOL...but you have to take it off before you drive it.....

BY the way....just wondern is that the.. hmmm... farmers daughter..??

[egronvold]

Very nice conversion :)

[frizzen]

Thank you ergonvold!

I thought so, but it seems like most of the in-person votes so far have been for the little flapper.

Yes, it IS the farmers daughter. (She thinks my tractors sexy)

[frizzen]

I knew it needed an exhaust to hide my Antenna up out of the body. Then it really ought to have a hand-throttle, well if it's got that it might as well have a shifter, then i need to drill the front wheel lug holes and chrome lug nuts...

https://imgur.com/hCG3u0Zh.jpg

https://imgur.com/TKemjoKh.jpg

Wait, where did the Farmall 1256 and Barge wagon come from?
But I DON'T even have another lot.
Oh no, looks like i'm on my way to becoming a Farm Collector...

[jerry56]

Looks like you have another project...

[Wombii]

Watch out! It seems like there are some projects sneaking up on you.

That's a great way to deal with an antenna tube.

[frizzen]

I know, it's just what the guy with "Project Attention Deficit Disorder" needed! (Finished projects are for suckers)

The little IH and Tonka in first post went to my dad. The big IH has a cracked and worn out front axle, but i liked the look if i really get into this RC Farm thing. The axle articulates and steers, so it's already much nicer than the new wildly swinging axles. It appears to have been new when the real tractors were, it probably likes the paint wear, just needs some grime and weathering for its 'work clothes'.

The Cockshutt needs a couple touches of paint, some anti-skid, Slow Vehicle Triangle, rear hubcaps, maybe a couple other little details.

[frizzen]

Ok, how's this looking now?

https://imgur.com/7HaW7oyh.jpg

https://imgur.com/XNDABalh.jpg

Backstory i'm aiming for this machine has been used through it's first life, restored into a show tractor, and gets out for some plow days and other light use.

I'm going to try to learn how to turn Some bad videos into A bad video. Also probably just a couple more details when i feel like it.

[jerry56]

I like how it turned out... looks good...

[frizzen]

Hopefully this doesn't suck, juggling a camera and remote, plus i'm trying to learn a video editor.

https://youtu.be/xiFamVvDfwY

I know it's a 6 cylinder with 6 forward gears and the rear track set very wide, but Sabine is still driving it pretty fast for as rough as my land is.

I should be careful that i don't go too crazy into the Farming world, i may need to have her dad show up and introduce "some of the other old crap around here that's not running..."

[2redrovers]

I can't help but think that a video of the farmer's daughter riding your cockshutt would belong on a different kind of forum.......

Yep, I'm here too (had to go somewhere after the other one went kaputt). I think I can help solve the belt pulley, got an old cell phone laying around? Strip it down and pull the micro motor that makes it vibrate, drill hole in the appropriate spot with the motor fitted so it is snug and about half way outside the body case. Add a pulley for looks and wire it up to run with power or maybe throttle. Oh and the tin can dangling on a string/chain so you don't lose it.

[Wombii]

And if you don't have an old cellphone to tear apart, it would most likely be the same type of motor in a micro servo.
Welcome, 2redrovers!

I can't believe how silent that tractor runs! Nice job on the mechanics.

[2redrovers]

Good thinking Wombii and thanks. Still mostly here in stalker/dad joke mode but better late than never... I am attempting to get something done with my jcb midi but struggling a bit.

That tractor is stealth mode 100, even has automatic uncoupling. I've used a servo to drive the jcb and it sounds like a battery drill in a blender with ice cubes.. It is slow though, so there's that

[frizzen]

Good to see you again Rovers! i was afraid you got stuck in the wreckage when Scale4x4 collapsed.

Well nobody complained about the jokes on my dumptruck, plus i'd much rather have a farmers daughter riding it than a guy...

The gearmotors do make some noise, but outside you'll never hear it. At a meet you'd never hear it over all the other stuff with Soundkits. In my house you hear the AG tread thumping more than motor noise. I'm still going to open them again and add a little more grease, there's a nice little pile of gears and spacers in them.

Yeah, Ertls barge wagon tongue doesn't have enough float, so the automatic uncoupling works if the ground is too uneven. I thought it was funny.

[jerry56]

I like the part where "Mr. Hand" helps out... I'm amazed you got all that wire and everything else in there....a feat in itself ...I like the outside the box thinking....

[frizzen]

Heh, yeah. Good thing we have friendly giants around here.
i don't know how you could do an hands off trailer coupling without changing everything over to a Lunette ring on trailer, and trying to make a bump-locking Pintle hook with release lever for tractor. Then run a rope from the release ring up to the seat, to hidden servo. Maybe it'd be worth it if i were building a Tug tow tractor instead of Cockshutt row crop. I shouldn't need to hit and drop trailers that much.

I dunno, i think trying to assemble it's *VERY much* inside-the-box thinking. And the box is small. And it is conductive. If i were going way too crazy tight, i'd have to step up to some "Table Top Trial Truck" electronics. If it fits in a 1/87 scale rc vehicle TTTT, it should fit anywhere!

[jerry56]

no just enough detail and motion to be fun.... nice and clean.

[frizzen]

Got an old truck-bed trailer safe enough to try dragging around

https://imgur.com/HAXOEwDh.jpg

Then some guy wanted to be pulled around town in a trailer to spread some message.
https://imgur.com/4cHIZaYh.jpg

But then ya gotta give equal time for the other guy too
https://imgur.com/6gGwZHwh.jpg

Looks like that spreader still works pretty well... all i know is we probably need some boots, it's getting pretty deep

[Tgrzes]

This was a nice little project! I really like how you stashed everything into such a tight space. Did you use the inexpensive ESC that I see mentioned in several threads? If so, would you be able to post a link?

[frizzen]

Thank you!

Yeah i used one of those cheap chinese Brushed-motor ESCs we've been talking about that are sold between 10-30 amps, and some have switchable brakes, some seem to be good for up to a 380 motor. I think this one got a "General Tso with Fried rice and an Egg roll'' brand? I don't know.

https://smile.amazon.com/Hobbypower-Brushed-Motor-Speed-Controller/dp/B00JXI3H6Y?ref_=ast_sto_dp

This one got 10a with no-brake. For this size tire and doing some drawbar pulls i may want to go higher amps eventually?

I'm using a Flysky fs-gr3 rx (that works interchangibly with a Redcat RCR-2C) on my Redcat 2ch tx, or it could bind to my flysky fs-i6 tx

MG90s servo.- used 1
Pkcell 2/3AA rechargable nimh 650mAh - used 6
3mm x 3mm shaft coupler adapter for boat motor - used 2
Motors probably came from Wish so searching a part number i gave earlier or hitting up Polulu is probably a WAY better chance of ever finding them again
Micro Jst connectors - handfull
Slide switch for charge / run select

[Tgrzes]

Thanks! At that price, definitely worth a try on a future project.

[frizzen]

Would anybody be able to get some detail pictures of a "Fair Shuttle" type of people-mover trailer?
The type i'm thinking of usually has a center isle so that an attendant could take money or check on people, and have outward facing bench seats on both sides that run down the length. Most of them have an awning with Fair info or promoting Sponsors.

Around here usually these are pulled in a Fair Train as a Double or Triple behind a Tractor. I'm guessing the chassis is setup something like a hay-wagon?

I said i was in 4-H, you knew eventually there'd be something about County or State Fairs...

[jerry56]

I've seen them but but it seems like they were all different... I would think you could build one just about anyway you wanted to.

[ddmckee54]

Most of the ones I've seen at fairs have been similar - but different. The ones I've seen have usually been on a converted wagon chassis with back to back bench seats and a foot rest that was a few inches off the ground. That made it easier to step on and off. They usually had a awning type of covering to keep the sun or rain off you as you traveled. Somewhere on the wagon would be a poster or banner displaying the name of the outfit providing the service. They traveled at a walking pace so you just got on and off when you wanted. Sometimes they would have a "Donations" jar so you could help out if you were so inclined.

You can always make it as a single wagon and say that you are making it safer to handle in a large crowd?

Don

[frizzen]

I figured they were really all just random 'home-builts' each venue or build shop came up with their own as needed. I'm just trying to get some ideas about how involved adapting some Ertl farm parts into one or two might be.

I was thinking something along these lines could be kinda fun to annoy the Truckers, i mean 'add diversity and crowd appeal to the layouts for meets & shows.'
http://thestatehousefile.com/wp-content/uploads/2016/08/Powell_StateFair4.jpg

[ddmckee54]

Yup, no rocket science to it at all. They're just a place to park your butt and your feet. All you need is a basic frame to keep the butt, foot and back boards from sliding around on the wagon running gear. Anything else is just bells and whistles.

I saw those guys were charging for the ride. The ones that I've seen were freebies - with donation jars for when you were feeling generous.

[frizzen]

Been working on getting broken equipment from some failed Carpet Farmers. The market for carpet has been pretty weak, and it's hard on machinery.

https://imgur.com/gQZvrowh.jpg

Then the barge wagon got a brass piece bent up that lets me pull doubles, so i shouldn't have to travel as much during harvest.

[jerry56]

This collection is coming along pretty well.

[frizzen]

Thanks jerry.
But best i can tell, it wouldn't really be much of a "Farm collection" without atleast 1 area full of "the old cr p that doesn't run".

There's a lot of Green tractors here, because "Nothing smells like a John"

I think i've reccently learned a new term that pretty well sums up what i've got going on over here: "Tetanus Farm".

Anyway, here's what i've got eased into that tree row behind the barn. The old nylint flatbed has a tree growing up through the cab, and the deere wheel loader its blocking, wasn't worth pulling it out just for a pic.

https://imgur.com/cVIPxtOh.jpg

Maybe it's got busted axles, can't find tires anymore that fit, it's transmission let go, a tree fell on it, the engines all worn out, i let Beauford drive it 1 friggin time, well i always wanted one of them... Besides, we might be able to find time to fix it after the harvest, or over the winter, or during the spring rains, i mean, we'll get around to it, it's on the list.

Or maybe it's still a fairly new rig but the computer just doesn't let it run, since ya know Deere won't open source anything, and they quit carrying parts to fix it. .. Right To Repair.

--
Ok... here's the Ford with the tree growing through it.
https://i.imgur.com/KhCd0fPh.jpg

As far as stuff with ''Actual'' plans:

The International Farmall 1256 (red with cab) has cracked & worn out steer axle, replace with a takeoff part, convert like Cockshutt
The Deere Square-fender Garden tractor has motors, needs a servo, and wagon cart for an RX and Battery
The Deere Gator should just need a set of gear motors, little servo, electronics
The Ford 7710 (blue) needs a front axle, i screwed it up pretty badly trying to make knuckles. Maybe brass wide, some stock ertl upgrade, tricycle?

Need to find some other 'walking dead' action figures. Thinking i need to put an old guy like Hershell or Dale in one of these

[jerry56]

:lol: LOL... yeah I guess you need that...

[skeeter]

The Deere Gator should just need a set of gear motors, little servo, electronics


Prior to moving into a smaller place with NO workshop, I was working on one of them Gators. I found the 24th scale Axial fits decent enough as a donor chassis for this build. The suspension will maker er ride a wee bit higher than the original version! One of these days I might could get around to starting that build again.

[frizzen]

Skeeter, i'd like to see what you did on yours if you feel like doing a thread.

I'd seen somebody driving this around.
https://imgur.com/PDt3KDKh.jpg

So i wanted one, or maybe some kind of little ugly industrial cart, found this cheap.
A Gator seemed like it would work around the farm, or taking people out to parts of the construction sites

[frizzen]

I heard ya liked carts. So now you can pull a cart, while pulling a cart, with your cart

They play follow the leader well, but don't track in a straight line. Nice.

Your getting a regular ol green acres thing goin on there.

[ddmckee54]

That Cockshutt must have one HELLUVA exhaust leak. Every time I forgot to take the can off the muffler of a tractor, it got blown off when the engine fired up.

Don
