Attach each new tine to the flange making certain it ismounted so that the cutting edge crosses over theflange and leads in rotation as shown in Figure 4-1.3. Replace 2 cap screws and fasteners. Tighten nuts toproper torque.TIne ReplacementFigure 4-1IMPORTANT: When ordering, be sure to ordergenuine Land Pride replacement tines only and toorder both right and left-hand tines.

Repeat “run-in” instructions at the beginning ofeach season and when moisture and/or condensationseizes the inner friction plates.Refer to Figure 4-2 below and Figure 4-3 on page 25 todetermine which friction clutch your tiller has. Followrun-In, disassembly, and assembly instructions for yourspecific clutch.Clutches With 4 Adjusting NutsClutch Run-InRefer to Figure 4-2 (View - A):1. Using a pencil or other marker, scribe a line across theexposed edges of the clutch plates and friction disks.2. Tighten all 4 nuts uniformly until spring load is lowenough that the clutch slips freely with PTOengaged.Clutches With 4 Adjusting NutsFigure 4-23. Start tractor and engage PTO for 2-3 seconds topermit slippage of clutch surfaces. Disengage PTO,then re-engage a second time for 2-3 seconds.Disengage PTO, shut off tractor, and remove key.Wait for all components to stop before dismountingfrom tractor.4. Inspect clutch and ensure that the scribed markingsmade on the clutch plates have changed position.Slippage has not occurred if any two marks on thefriction disk and plate are still aligned. A clutch thathas not slipped must be disassembled to separatethe friction disk plates. See “Clutch Disassembly &Assembly” on page 24.Refer to Figure 4-2 (View - B):5. Turn all 4 nuts fully back if no two marks on thefriction disk and plate are still aligned. Clutch is readyfor use.6. The clutch should be checked during first hour oftilling and periodically each week. An additional setof scribe marks can be added to check for slippage.23696
