increase tractor size as it leads to tine bend-ing and failure.

11. Turning:Raise the unit out of the ground when makingturns. This will prevent bending or twisting ofthe tines.

12. Reversible Points/Shovels:

A shovel is attached to thebottom of each tine and en-gages the soil. A variety ofshovels can be used anddepends on the application.Raise the machine above theground and support on a safetystand. Replace plow bolts if theheads are worn when changingshovels. Do not allow shovelsto wear so much that the tinewears.

13. Operating Hints:

a. Know the working area beforestarting. Do not work wherethere are shallow undergroundobjects such as wires, waterlines, rocks, roots or otherobjects. Damage can be doneto the machine or tractor froman underground object.

b. When contacting somethingunder the ground, it may benecessary to back up a fewinches while lifting to releasethe shovel from the object.

c. In very hard soil conditions, itmay be necessary to addsome weight to the frame tohelp the shovels penetrate thesurface. Add only as muchweight as required. Do notuse more than 200 lbs.

d. Use the "position" mode on the3 point hitch to operate at apre-determined depth. Watchthe soil on the tines to knowthe depth. Use the "float"mode to allow the frame tofollow the ground contour.

e. Keep the shovels in goodcondition. A badly wornshovel will require extra powerto pull and may allow the tineto wear.

f. Be sure the shovels are out ofthe ground when starting tomove. It is best to be movingand then lower the machineinto the ground to preventoverloading the tractordrivetrain.

g. Use the optional gage wheelsto help control the operatingdepth. Set the position of thewheel strut to set the operatingdepth.

6 TROUBLE SHOOTING

23

S-Tine Cultivators pull a series of S-Tine shanks and points through the soil to cultivate or form seedbeds.It is a simple and reliable system that requires minimal maintenance.

In the following section, we have listed many of the problems, causes and solutions to the problems thatyou may encounter.

If you encounter a problem that is difficult to solve, even after having read through this trouble shootingsection, please call your local dealer or distributor. Before you call, please have this Operator's Manual andserial number from your Cultivator ready.

PROBLEM CAUSE SOLUTION

Shovel won't penetrate soil. Hard ground conditions. Replace shovels if badlyworn.

Be sure 3 point hitch is set in"float" or "draft" mode.

Add weight to frame.

High power required. Wrong shovels. Install smaller shovels.

Shovels worn. Replace shovels.

Uneven job. Changing soil conditions. Install gauge wheels to keepframe level.
