OPERATION
IMPORTANT: For proper operation, the planter frame must operate
level and at the correct height, usually 20” – 22” while in operation.
In hard no-till conditions the desired operating depth may not be possible. Tighten spring
nut to maintain depth if spring is flexing rather than lower coulter to obtain maximum
depth. Planter weight may limit operating depth in hard conditions, particularly with
mounted or semi-mounted planters. Be sure planter has enough weight to keep drive
wheels on the ground during operation or plant populations can be drastically affected.
1. Set/mount coulter blades to run perpendicular to the soil. Operation depth and blade
wear can be affected if the coulter is mounted crooked or if the toolbar is not level side to
side.
2. After a few hours of use, check all bolts for tightness and proper torque.
3. After a day of use (10-12 hours) check coulter hubs for loose bearings. There should be
no endplay in the hub bearings allowing the blade to wobble. If necessary, remove
hubcap and cotter pin and adjust the slotted nut to remove wobble, recommended torque
of 15 ft. lbs. and re-insert cotter pin. If the wobble or looseness cannot be corrected, the
bearings, cups and seals will need to be replaced.
DO NOT USE WORN OR DAMAGED PARTS.
