! WARNINGIt is the operator’s responsibility not to allow anyone near theDisc Harrow during its operation.

! CAUTIONBe sure that you are not working over any underground wiring,pipes, or other obstructions. If there is any doubt, call yourpublic service agency.

• Follow all directions on the safety labels.

• Never carry passengers or use the Disc Harrow as awagon to carry things.

• Make sure all safety labels are in their proper locationand in good condition before operation.

• Never work under the unit without properly blocking theunit up.

• Before working the soil contact your local utilityservices, so that they may mark the location of anyunder ground utility services in the area. Be sure to askhow close you can work to the marks or flags theypositioned.

• All nuts, bolts, screws, and fasteners should bechecked daily for tightness. Refer to the Torque ValueChart in the “Appendix” section on page 20.

• Do not alter the Disc Harrow in a way which willadversely affects its performance or reliability or use theDisc Harrow for a purpose for which it was not designed.

Transporting

! CAUTIONWhen traveling on public roads whether at night or during theday, use accessory light and devices for adequate warning tooperators of other vehicles. Comply with all federal, state andlocal laws.

Unit should be lifted as high as the tractor will allow beingsure the unit is clear of the ground when transportingbehind tractor.

Care should be taken as negative tractor front end weightcould cause loss of control of tractor. A safe speedshould be maintained during transporting. Tractorweights may need to be added to front end of tractor tomaintain steering control. See tractor manual.

Do not lower unit while transporting on pavement,blacktop or road. Damage to unit and or road may occur.


turning; and, leave enough clearance so the DiscHarrow does not contact obstacles such asbuildings, trees or fences.

2. Select a safe ground travel speed when transportingfrom one area to another.

3. When traveling on roadways, transport in such a waythat faster moving vehicles may pass you safely.

4. When traveling over rough or hilly terrain, shift tractorto a lower gear.

Field Operation


1. After initial adjustments have been made and tractor ishooked up to Disc Harrow, you are ready to startdiscing.

2. Lower Disc Harrow to ground and start movingforward. Your travel speed will be determined by soilconditions. You may find you want more or less angleon the discs to do the job. Refer to “Disc Angling” onpage 14 for changing angles of disc gangs.

3. When turning, lift unit up out of ground.

! CAUTIONDamage to the harrow can occur if it is not lifted out of theground before turning.

4. Do not disc in reverse (traveling backwards). The DiscHarrow is designed for working the soil while travelingforward only. Damage to the harrow may occur.Recommended procedure for corners or tight placesis:

a. Lift unit up

b. Back up into corner or other tight areas

c. Lower unit to ground and proceed with discinggoing forward

5. Do not cross a ditch at a 90 degree angle (straight on)!Damage to the disc and/or tractor may occur whilecrossing at a 90 degree angle. Always cross a ditch ona diagonal.

General Operating InstructionsBefore putting your Land Pride Disc Harrow into serviceyou must thoroughly review the Operator’s Manual. Onceyou have read the Operator’s Manual and properlymounted your Land Pride Disc Harrow on your tractor,you should be ready to head for the work site. You shouldhave already removed any sizeable tree limbs, rocks, ordebris from this area. Do not attempt to disc wet or muckysoil and all areas should be well drained and capable ofbeing walked on without having the soil stick to yourshoes.

Discing action will commence as soon as the unittouches the ground and tractor begins to move forward.Your travel speed forward will be determined by soilconditions and available tractor horsepower. Never try todisc in reverse and when you reach the end of a pass,pick the unit up before turning. Trying to turn sharply withthe unit in the ground will cause extreme side loading onthe discs and may cause damage. Making disc gangadjustments is relatively easy by raising the disc off of theground, placing safety blocks under the frame, pulling thelocking pin, making the required adjustment, and thenreverse the process till you are back in action. Theoperator’s manual illustrates this process very clearly.

1/03/06 DH1048, DH1060,

Ground conditions and the finish you require willdetermine how you position the angles of your front andrear disc gangs. Both of the front and rear disc gangshave four angle adjustment positions. The best groundfinish will usually be achieved when the rear gang is setat a slightly lesser angle than the front gang. The moreaggressive you set the angle of the gangs, the moreaggressive the cutting action in the soil profile will be.The more aggressive the cutting action is, the morehorsepower will be required to pull your unit. Achievingthe desired effect may require a little experimentation inyour given conditions. If the soil is building up on orsticking to your discs then the soil is too wet and discingoperations should be discontinued until the ground is dryand more workable.

Once you are finished using your disc, park it on a dryand level surface, clean it, and make it ready for the nextuse. With a little practice you will be able to achieveexcellent results from your Land Pride Disc Harrow. See“Features and Benefits” section or “ProductSpecifications” for additional information andperformance enhancing options.


Section 3: Adjustments



! CAUTIONBe careful when working with disc blades as the edges aresharp. Wear gloves when working around disc blades!

Disc AnglingRefer to Figure 3-1:The Disc Harrow is designed for ease of angling. Byusing the handles the front or rear discs can be adjustedto the desired angles.

IMPORTANT: Always turn tractor key off and removekey before performing any maintenance oradjustments on Disc Harrow.

IMPORTANT: Properly block and secure Disc Harrowin lift position prior to changing angles of gangs orduring maintenance. Keep feet from under disc bladesduring adjustments or maintenance.


Disc AdFig

Front discs on all series have four angle positions:(0, 7, 14 and 21 degrees.)

Rear discs on DH10 and DH15 Series have four anglepositions: (0, 7, 14 and 21 degrees.)

Rear discs on DH25 Series have three angle positions:( 7, 14 and 21 degrees.)

Adjust disc gangs as follows:

• DH10 Series: Remove hitch pin (#1). Slide disc gang(#2) to desired position and replace hitch pin.

• DH15 & DH25 Series: Remove hitch pin (#1) and hairpin cotter (#3). Slide handle (#2) to desired positionand replace hitch pin and hair pin cotter.

• For a better ground finish, angle the rear gangs at alesser angle than the front gangs.

NOTE: The more angle you have the more aggressivethe cut will be and the more horsepower will berequired to pull your unit.
