OPERATION
PREPARING THE TOOLBAR
Drawbar Height
The Yetter model 6300 coulter cart is designed to operate on tractors with drawbar heights from 18” to 22” from the
ground to the top of the drawbar. On certain tractors the drawbar can be turned over to obtain the correct height.
Hydraulic Hook Up
DANGER:
Inspect and replace worn or frayed hydraulic hose. Keep all connections tight,
escaping hydraulic fluid under pressure can have sufficient force to penetrate the skin and cause
serious personal injury. Fluid escaping from a small hole can be almost invisible. Use a piece of cardboard
or wood rather than hands to search for suspected leaks. Failure to heed may result in personal injury or
death.
The Yetter coulter cart requires two remote hydraulic valves on the tractor for proper operation. Before operating in
the field, perform the following steps.
1. Connect the Yetter cart to the tractor drawbar before operating the cart hydraulic system. Check the tractor
hydraulic system fluid level. Filling all four cylinders with fluid will require approximately 2 ½ gallons. DO
NOT operate tractor hydraulics when fluid level is too low.
2. Disconnect rear lift cylinder rod-end pins when the weight is relieved from the cylinders. Space the cylinder
away from the frame by placing 4” wide blocks between the cylinder and frame to allow the rods to extend
freely.
