Because
we were going to run the picker with a tractor
with dual hydraulics, we installed a 12V
electric double selector valve. One side of the
valve raises the dump box, and the other raises
the windrower. Then we stacked another valve
because we decided to modify the hitch on the
picker, making it a hydraulic swing hitch. With
the swinging hitch we can pull the picker in the
field without running over the rocks that we
were trying to pick.
We mounted a ram on the side of the new
swing hitch so we can control the position of
the hitch from the cab.
Here
is our rock rake hooked to our Allis Chalmers
D17
This
is our rock picker. It is a Crown rock picker.
Summers Mfg currently manufactures this same
model.
The
tires on the rock picker were 11sl-15 and giving
us trouble. So we changed them to Super Single
semi tires.
Here are some videos of us raking and picking rocks on the farm.
