C. Block tires to prevent movement after hitch pin is removed.
D. Check that hitch pin is not bound with side or front to back pressure. If hitch pin is not free,
carefully reposition tractor.
E. With hitch pin free, if hitch piece lifts up on tractor drawbar, negative tongue weight exists.
DO NOT UNHOOK LAND ROLLER WITH NEGATIVE TONGUE WEIGHT. Negative tongue
weight can be caused by excessive ground slope (front of hitch higher than center section)
or incorrect machine adjustment (wings not rotated far enough ahead to transfer weight to
hitch piece). Relocate Land Roller to a more level surface, if negative tongue weight still
exists, follow “STEPS REQUIRED TO UNFOLD FROM TRANSPORT TO FIELD POSITION”
and adjust Land Roller to create adequate tongue weight.
NOTE: After any machine adjustment, it is very important to follow “STEPS RE-
QUIRED TO FOLD FROM FIELD TO TRANSPORT POSITION”. In addition to these
steps, it is very important to retract hydraulic cylinders slowly to insure Cylinder
Attach Eye Bolts are correctly adjusted and that hydraulic hoses and wires are not
stretched or pinched.
F. If hitch piece is held up by tractor drawbar and can not be lifted off, positive tongue weight
exists. If positive tongue weight exists, carefully follow steps G through J.
G. Rotate jack into vertical position, place sturdy block under jack to distribute load over larger
area and extend jack until hitch piece just lifts off tractor drawbar.
H. Disconnect wiring harness, hydraulic hoses and safety chain.
I. Recheck that hitch pin is free, if so, stand to the side of the hitch and remove hitch pin.
J. Carefully drive ahead.
