Resumen del manual
With careful inspection and routine maintenance, you can avoid costly down time and repair. The parts on your Rotary Tiller have been specially designed and should only be replaced with genuine Land Pride parts. Do not alter the tiller in a way which will adversely affects its performance. Check all bolts and pins after using the unit for several hours and on a regular basis thereafter to insure they are tight and secured. Replace worn, damaged, or illegible safety labels by obtaining new labels from your Land Pride Dealer. ! CAUTION For safety reasons, each maintenance operation must be performed with tractor PTO disengaged, tiller lowered completely to the ground or onto support blocks, tractor engine shut off, and ignition key removed. Tine Replacement Refer to Figure 4-1: ! WARNING Worn tines may be very sharp! 1. Remove 2 hex head cap screws and fasteners from each tine being replaced. Remove tine. 2. Attach each new tine to the flange making certain it is mounted so that the cutting edge crosses over the flange and leads in rotation as shown in Figure 4-1. 3. Replace 2 cap screws and fasteners. Tighten nuts to proper torque. TIne Replacement Figure 4-1 IMPORTANT: When ordering, be sure to order genuine Land Pride replacement tines only and to order both right and left-hand tines. Always install tines with cutting edge facing direction of rotation. IMPORTANT: Remove and install one tine at a time to ensure they are oriented correctly when installed. 22269 Driveline Protection Tiller drive components are protected from shock loads with either a two plate friction clutch or a shear bolt. Shear bolt protection is discussed on page 25. Friction clutches should be “run-in” prior to initial operation and after long periods of inactivity to remove any oxidation that may have accumulated on the friction surfaces. Repeat “run-in” instructions at the beginning of each season and when moisture and/or condensation seizes the inner friction plates. Refer to Figure 4-2 below and Figure 4-3 on page 25 to determine which friction clutch your tiller has. Follow run-In, disassembly, and assembly instructions for your specific clutch. Clutches With 4 Adjusting Nuts Clutch Run-In Refer to Figure 4-2 (View - A): 1. Using a pencil or other marker, scribe a line across the exposed edges of the clutch plates and friction disks. 2. Tighten all 4 nuts uniformly until spring load is low enough that the clutch slips freely with PTO engaged. Clutches With 4 Adjusting Nuts Figure 4-2 3. Start tractor and engage PTO for 2-3 seconds to permit 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 dismounting from tractor. 4. Inspect clutch and ensure that the scribed markings made on the clutch plates have changed position. Slippage has not occurred if any two marks on the friction disk and plate are still aligned. A clutch that has not slipped must be disassembled to separate the 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 the friction disk and plate are still aligned. Clutch is ready for use. 6. The clutch should be checked during first hour of tilling and periodically each week. An additional set of scribe marks can be added to check for slippage. 23696 24 RTR10 & RTR15 Series Rotary Tillers 311-431M 11/01/11 Section 4: Maintenance & Lubrication Table of Contents Clutch Disassembly & Assembly If clutch run-in procedure indicates that one or more of the friction disks did not slip, then the clutch must be disassembled to separate the friction disks. IMPORTANT: Before proceeding, secure clutch firmly in a clamping device to prevent injury. 10435 Step 2 Remove backup ring, lock collar, compression spring, bottom backup ring, and balls. Step 3 Tighten the four hex nuts uniformly until the clutch pack and hub are loose. Step 4 Bend all four retaining lugs out on edge of clutch housing. Step 5 Remove thrust plate with Belleville Springs and lug rings to access friction disks and hub for inspection or service. 2-Plate Disassembly Step 1 Remove snap ring. Step 6 Inspect friction disks and hub. 10449 Step 2 Compress Belleville Springs to the pressure plate by tightening the four hex nuts and then placing the assembly into the clutch housing. Step 3 Bend retaining lugs inward over the Belleville Spring edges to secure the spring before backing the four hex nuts off. Step 4 With lugs bent in, loosen the four hex nuts completely to the end of the threaded studs. Step 5 Insert greased balls. Step 6 Install bottom backup ring, compression spring, lock collar, and top backup ring. Step 7 Install snap ring. Step 1 Place hub and friction disks into the housing. 2-Plate Assembly 11/01/11 RTR10 & RTR15 Series Rotary Tillers 311-431M 25 Land Pride Section 4: Maintenance & Lubrication Table of Contents Clutches With 8 Hex Soc...
