Last yr at this time I was third done seeding, but the weather this yr....
So I've been working on a few new projects in the hobby shop
Broke all these stones except the big white one, once that stone split the color of the core was a dark purple & that color of stone seems to be the hardest of them all. After I fished the two pieces out, started up jaw again & tossed in one half, then the jaw broke it down. Then tossed in other half & it eventually crumbled too.
The small pulley on motor is only driving the jaw to about 290rpm, it says on the website not to exceed 375rpm... I'll try a bit bigger motor pulley & experiment some more to see if added speed helps.
The crush size is a bit smaller than 3/4 minus road gravel
