OPERATION
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 2000 Series All Steer Plus ™ Fertilizer Toolbar requires two remote hydraulic valves on the tractor
for proper operation. Before operating in the field, perform the following steps.
1. Connect the All Steer Plus ™ Fertilizer Toolbar 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 3-4 gallons. DO NOT operate tractor hydraulics when fluid level is too
low.
2. Connect the hoses from the All Steer Plus ™ Fertilizer Toolbar to the tractor. The hydraulic
hoses are provided with the adapter attached. Use ¾-16” standard thread quick coupler tips.
3. Hold hydraulic lever in extend position for 15 seconds after cylinders are fully extended to purge
air from the system.
4. Recheck tractor fluid level and refill if necessary.
5 Cycle cylinders back and forth a couple of times to see that they operate together. Hold the lever
in the extended position a few seconds after each cycle for additional air purging.
