OPERATION
FIELD OPERATION
WARNING:
Do not allow children to operate this equipment. Do not allow riders on the
tractor. Failure to heed may result in personal injury or death.
Lift cylinders raise the cart. Since the attached implement is a 3-point mounted unit it will raise with
the cart. The cart is lowered when the lift cylinder lifts the transport wheels off the ground. The
wheels of the implement then support the cart.
The toolbar cylinders regulate the depth of the coulters on the cart. A parallel linkage allows
adjustment to the coulter depth without affecting the depth setting of the implement.
The planting depth is controlled by the gauge wheel setting of the implement unit. See owner’s
manual for your implement.
NOTE: In extremely difficult no till conditions such as hard packed soil it may be necessary to fill
the transport tires with fluid to add weight to the rear of the cart forcing the coulters to cut. The
spring adjustment nut on the coulters can also be tightened. Also, an optional weight kit 6300-129
(10 suitcase weight capacity) is available.
IMPORTANT: Do not adjust the coulter depth so deep that the coulter hubs are running in the soil.
This will cause premature bearing failure.
COULTER ADJUSTMENTS
COULTER SPRING TENSION
Spring tension is set at the factory with ¾” locknut flush with the end of the spring rod. In hard or dry
conditions additional spring pressure may be attained by tightening the locknut down a maximum of ½”.
COULTER BLADE TRACKING
Minor adjustments to align the coulter blades with the attached implement can be made by loosening the
set bolt in the shank clamps and rotating the offset shanks to align the coulter with the opener on the drill.
IMPORTANT: Do not adjust the coulter depth so deep that the coulter hubs are running in the soil,
this will cause premature bearing failure. See coulter operation manual for further information.
