Thanks guys
. I think I am going to use a servo to run the blade but it will be a 360 degree with a screw drive hidden in the front under the hood ahead of the axle. If that doesn't work out to have enough speed or power I will build hydraulic rams for it. I'm hoping to only use hydraulics for the grapple though if I can get away with it. I'm going to start on the grapple today but even without it this thing is getting BIG!
Thanks for looking, Reg
