7.1.2 Hydraulic Strut Lift (option): (Rear struts equipped with rephasing cylinders.)
1. Move the defoliator on to a flat and level floor
for accurate measurements.
2. Lower the defoliator front hitch cylinders to
approximate operating height.
3. Check tire pressure to ensure both sides are
correctly inflated.
4. Measure the distance between the drum #3
flails and ground, or rear frame tube and
ground on the very outside of the left and right
hand sides of the defoliator and record dis-
tance.
5. Jack up the corner of the frame to remove the
load from the strut assembly and the tires. Se-
curely block the frame with suitable jack stands
or wooden blocks.
6. Remove the lower cylinder pin and loosen the bolt clamping the cylinder clevis end to the rod.
7. Screw in the cylinder clevis end on the side that is high until machine is level.
8. Retighten clevis and replace pin.
9. Lower frame to ground and confirm level. Repeat steps 5 - 8 if required.
7.2 Height
Follow the guidelines below for initial setup and adjustment of defoliator height.
7.2.1 Initial height set - up
1. Move the defoliator to a flat and level floor.
2. Lower the defoliator front hitch cylinders to approximate operating height.
3. Evenly lower the rear struts to approximate operating height.
4. Start with both 2
nd
and 3
rd
drums at the same height with flails approximately 1 inch below the
average height of an estimated beet crown.
5. Install as many cylinder depth stops as possible evenly in both front cylinder and rear cylinders if
equipped.
6. Lower cylinders onto depth stops and check initial setting.
7. Add additional depth stops to level machine and set height to desired level.
