Except for RTA1042, the tillers can be shifted amaximum offset of 7" left or right of the gearbox input shaft by moving the hitch clevises (#1) 7" to the right or left. The RTA1042 is built to be offset 26" to the right when the hitch clevis are set an equal distance away from the gearbox input shaft. The unit can be shifted a maximum of 7" to the left by moving the hitch clevis 7" to the right. For best tillage results, adjust tiller offset to the right by moving the hitch clevis to the left far enough to cover the tractor’s right rear wheel tread marks. 1. Loosen hex nuts (#2) until clevises (#1) can be moved on the front tube. 2. Slide lower hitch clevises (#1) an equal amount left or right up to 7" while holding the 26 7/8" distance between clevises. 3. Retighten hex nuts (#2) to the correct torque value. RTA Tiller Hitch Offset Figure 3-1 30352 Adjust To Suit Hold 26 7/8" Adjust Clevis Left or Right Up To 7" Maximum RTA15 Tiller Hitch Sideshift Refer to Figure 3-2: The three point and gearbox can be sideshifted to the left of tiller center for various working conditions. ! CAUTION After sideshifting check to see that the PTO shaft clears all shields on the tiller, tractor, and the tiller hitch. If not, decrease sideshift until clearance is obtained. 1. Loosen the two u-bolts (#2) which hold the top hitch/gearbox frame (#1) to the front tube. 2. Loosen the two bolts (#3) which hold the top hitch/gearbox frame (#1) to the rear of the tiller. 3. Loosen the two u-bolts (#4) which hold the lower hitch clevises (#5) to the front tube. 4. Slide the top hitch/gearbox assembly to the desired location. 5. Re-center the lower hitch clevises with respect to the gearbox. Retighten all bolts and nuts referring to the Torque Values Chart in the “Appendix” section on page 32. RTA15 Tiller Hitch Sideshift Figure 3-2 NOTE: For maximum offset, the left lower hitch clevis can be located on the left hand side of the left end plate. 22192 11/01/11 RTA10 & RTA15 Series Rotary Tillers 311-252M 19 Section 3: Adjustments Table of Contents Drive Chain Refer to Figure 3-4: The tension on the drive chain can be easily adjusted by using the chain tightener stud. Should backlash occur, loosen the nut and torque the stud clockwise to 20 - 30 foot pounds and tighten nut to 400 foot pounds. Rear Deflector Refer to Figure 3-3: Rear deflector (#1) can be adjusted closer to the ground to produce a fine soil texture or can be raised to produce a coarse soil texture. Adjust rear deflector by repositioning chain (#2) in slot “A”.

Raise tiller off the ground. Place a support under the tiller (not under the skid shoes) and lower the tiller onto the support. Make certain the tiller is secure resting on the support before working on or around the tiller. 2. Always place tractor in park, set tractor brakes, shut tractor engine off, and remove switch key before dismounting the tractor. 3. Loosen pivot bolt (#1) at the shoe’s front. 4. Remove adjusting bolt (#2) at the shoe’s rear. 5. Adjust skid shoe (#3) to desired location. 6. Reinstall adjusting bolt (#2) and tighten adjusting bolt and the pivot bolt (#1) to the correct torque. NOTE: Tilling depth is the vertical distance from bottom of skid shoes to bottom of lowest tine. Be certain both skid shoes are adjusted the same. Skid Shoe Adjustment Figure 3-5 30051 11/01/11 RTA10 & RTA15 Series Rotary Tillers 311-252M 21 Section 4: Maintenance & Lubrication Table of Contents Section 4: Maintenance & Lubrication Maintenance Proper servicing and adjustment is the key to the long life of any implement. 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 the 2 hex head cap screws and fasteners from the tine being replaced and then remove tine. 2. Attach new tine to the mounting flange making certain it is positioned so that the cutting edge crosses over the mounting flange and leads in rotation as shown in Figure 4-1. 3. Replace rem...
