GENERAL DESCRIPTION OF THE ROCKPICKER
The Rockpicker is designed to pick up rocks while driving in a cultivated field without the need
to stop to pick up the rocks.
The hitch is hydraulically operated to move from the transport position to the operating position.
The operating position moves the Rockpicker to the right of the tractor so the tractor treads do
not push rocks into the soil. When the Rockpicker bucket is full, the operator moves the hitch
to the transport so the Rockpicker follows the tractor to the rock dumping location.
The Rockpicker apron is positioned by the operator to be just above the surface of the soil. The
spring loaded pickup bats rotate on a hydraulically operated reel. As the rotating pickup bats
encounter rocks, they push the rocks across the apron and into the Rockpicker bucket. The
apron and bucket allow any moved soil to fall back to the ground.
For unloading the rocks, the Rockpicker is backed into the dumping location. The hydraulic
cylinders are activated to raise the rock bucket. As the bucket israised, ittiltstodump the rocks
out.
When the Rockpicker is picking rocks it uses hydraulic power from the tractor to position the
apron and to rotate the reel with the spring loaded rock bats. When the Rockpicker is moving
from transport position to operating position, a hydraulic cylinder is activated to move the hitch.
When the Rockpicker is dumping the rocks, the hydraulic lift cylinders lift the rock bucket and
tilt it to dump the rocks.
The operator of the Rockpicker is located in the tractor cab where they drive the tractor, control
the speed of driving, the operation of the hitch position, the rotating rock bat reel and the
dumping of the rocks.
The Rockpicker is transported on the wheels of the Rockpicker.
INTENDED USE OF THE ROCKPICKER
• The Rockpicker is designed to pick up rocks that are on the surface or near the surface of
a cultivated field and then to move those rocks to a storage location.
• The Rockpicker is designed to lift the rocks that have been picked up and to dump them.
• The Rockpicker is intended for use in field farming applications.
• The Rockpicker is intended for use in locations that are not near people or animals who
could be harmed by rocks that are thrown into the rock bucket.

Section 2 - Transporting the Rockpicker
Page 2-1
Transporting
Only tow the Rockpicker behind a
properly sized and equipped
tractor or vehicle which exceeds
the weight of the loaded
Rockpicker by 50%.
Shut off the tractor engine before
attaching the rockpicker or
hydraulics.
Do not allow children or other
people to ride on the tractor or
Rockpicker. Falling off can result
in serious injury or death. Impact
from thrown rocks can result in
serious injury or death.
The rockpicker is designed for off
road use only. To transport on
public roads consult with local
traffic regulations.
Do not transport the rockpicker
with rocks in the bucket.
Do not transport the rockpicker
with the bucket raised.
1. Adjust the position of the tongue plate for
the rockpicker to be level.

adjusting the picker’s collecting apron
height and dumping the bucket when
full of rocks.
- The second set of hoses is used to
drive the rock picker reel motor.
- The third set is for the hitch hydraulic
cylinder.

when there are there are only 2
remotes on the tractor.
- The selector valve directs the
hydraulic oil from the reel motor to
the hitch cylinder.
7. Raise the pickup apron.
