DANGER:

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 VTT 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 Yetter VTT 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.

OPERATION

WARNING:

tractor or implement. Failure to heed may result in personal injury or death.

IMPORTANT: Do not operate the coulter depth so deep that the coulter hubs are in the soil, this will cause premature bearing failure.

Yetter Model 2000 Series Vertical Tillage Tool¥ coulters are designed for tillage 3” to 5” deep and to be operated 6-10 mph.

Do not allow children to operate this equipment. Do not allow riders on the

• During assembly, the coulters should be set up to swivel. This reduces the side load on the coulter during operation.

• Set/mount coulter blades to run perpendicular to the soil. Operation depth and blade wear can be affected if the shank is mounted crooked or if the toolbar is not level side to side.

• After a few hours of use, check all bolts for tightness and proper torque.

• 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. 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.

IMPORTANT: For proper operation, the Vertical Tillage Tool¥ frame must operate level.

• Level the toolbar frame so that the coulter blades are the same depth front to back and side to side.

In hard no-till conditions the desired operating depth may not be possible. Tighten spring nut might be necessary, to maintain tillage depth.

Vertical Tillage Tool¥ machine weight may limit operating depth in hard conditions. Use enough ballast to keep the transport wheels on the ground during operation.

maintain coulter blade depth.

Drawbar Height

The Yetter 2000 Series Vertical Tillage Tool tm 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. Proper operation of the V.T.T. requires that the frame is level: front to rear as well as side to side.

If needed, add ballast or weight to

Our name

Is getting known

Just a few years ago, Yetter products were sold primarily to the Midwest only. Then we embarked on a program of expansion and moved into the East, the South, the West and now north into Canada. We’re even getting orders from as far away as Australia and Africa.

So, when you buy Yetter products . . .you’re buying a name that’s recognized. A name that’s known and respected. A name that’s become a part of American agriculture and has become synonymous with quality and satisfaction in the field of conservation tillage.

Thank you.
