The driveline must be lubricated before putting it into service. Refer to “Lubrication Points” on page 50. The tractor’s PTO shaft and cutter gearbox shaft must be aligned and level with each other when hooking-up the driveline to the tractor. Refer to Figure 1-5: 1. Start tractor and slowly engage 3-Point controls to move lower arms until the PTO shaft for the speed increaser is aligned and level with tractor PTO shaft. Securely block cutter in this position. 2. Place tractor gear selector in park, shut tractor engine off, set park brake, and remove switch key. 3. Slide inner yoke of driveline over speed increaser shaft and secure with locking collar. 4. Slide outer yoke of driveline over tractor PTO shaft and secure with locking collar. 5. Push and pull on driveline yokes to be certain they are securely fastened to the speed increaser and PTO shafts. 6. If driveline yoke will not lock in place, skip to “Check Driveline Collapsible Length” below. IMPORTANT: Two small chains are supplied with the driveline. To keep driveline shields from rotating, these chains must be attached to the outer and inner driveline shields and to the cutter and tractor. 7. Attach safety chain on the inner driveline shield to the parallel arm frame. Re-latch safety chain to the inner driveline shield. 8. Attach safety chain on the outer driveline shield to the tractor frame. Re-latch safety chain to the outer driveline shield. 9. Continue with “Check Driveline Collapsible Length” below. Check Driveline Collapsible Length IMPORTANT: A driveline that is too long can bottom out causing structural damage to tractor and cutter. Always check driveline collapsed length during initial setup, when connecting to a different tractor, and when alternating between using a quick hitch and a standard 3-Point hitch. More than one driveline may be required to fit all applications. 1. Make sure driveline is properly installed and level before checking driveline collapsible length. (Refer to “Driveline Installation” instructions on page 15.) Refer to Figure 1-5: 2. With driveline level, measure (“B” dimension) back from universal joint shield to end of outer driveline shield as shown in Figure 1-5. 3. If measurement is 1" or more, skip to “Check Driveline Maximum Length” on page 16. If measurement is less than 1", shorten driveline using instructions provided under “Shorten Driveline” on page 16. 22009 Shortening PTO Driveline Shields & ShaftsFigure 1-5 10/11/12 RCP2660, RCPM2660, RCP3060 and RCPM3060 Parallel Arm Rotary Cutter 316-111M 15 16 Section 1: Assembly & Set-up 10/11/12 RCP2660, RCPM2660, RCP3060 and RCPM3060 Parallel Arm Rotary Cutter 316-111M Table of Contents Shorten Driveline Refer to Figure 1-5: Be sure to check driveline collapsed length first. If required, shorten driveline as follows: 1. Un-hook driveline and safety chain from tractor PTO shaft. Pull outer and inner drivelines apart. 2. Reattach outer driveline to tractor PTO shaft. Pull on inner and outer driveline yokes to be sure universal joints are properly secured. 3. Hold inner and outer drivelines parallel to each other: a. Measure 1" (“B” dimension) back from outer driveline universal joint shield and make a mark at this location on the inner driveline shield. b. Measure 1" (“B” dimension) back from the inner driveline universal joint shield and make a mark at this location on the outer driveline shield. 4. Remove driveline from tractor PTO shaft and speed increaser shaft. 5. Measure from end of inner shield to scribed mark (“X” dimension). Cut off inner shield at the mark. Cut same amount off the inner shaft (“X1” dimension). 6. Measure from end of outer shield to scribed mark (“Y” dimension). Cut off outer shield at the mark. Cut same amount off the outer shaft (“Y1” dimension). 7. Remove all burrs and cuttings. 8. Continue with “Check Driveline MaximumLength”. Check Driveline Maximum Length Refer to Figure 1-6: The driveline maximum allowable lengthmust, when fully extended, have aminimum overlap of profile tubes by not less than 1/2 the free length with both inner and outer profile tubes being of equal length. 1. Apply multi-purpose grease to the inside of the outer shaft and reassemble the driveline. 2. Assemble the two driveline profiles together with just 1/2 overlapping of the profile tubes as shown. Once assembled, measure and record maximum allowable length here. ________ 3. Continue with “Check Driveline Interference”. Driveline Maximum Extended Length Figure 1-6 24804 Outer Shielding has been removed for clarity. Check Driveline Interference 1. Make certain driveline yokes and safety chains are properly attached. See steps 7 -9 on page 15. 2. Start tractor and raise Parallel ArmRotary Cutter just enough to remove support blocks from under the cutter. 3. Slowly engage tractor hydraulic 3-Point control lever to lower cutter while checking for sufficient drawbar clearance. Move drawbar ahead, aside, or remove if required. Refer to Figure 1-7: 4. With PTO off, rais...
