Make sure the tractor is equipped with the correct PTO shaft. Change shafts if needed.922. Shorten or remove the tractor drawbar to avoid interference when raising and lowering the mower.923. Board the tractor and start the engine. Position the tractor to the mower with the 3-point lift arms positioned at the same height and to the outside of the mower hitch pins. Note: Set the 3-point lift control to “Position Control” so that the...924. Turn off the tractor engine and dismount.925. One lift arm at a time, position the tractor lift arms over the A-frame hitch pins. Insert linch pins to retain lift arms to the mower.926. Walk around to opposite side and repeat procedure for remaining lift arm and hitch pin.927. Extend or retract 3-point top link to align its end hole with the holes of the mower’s top link. Insert the top link hitch pin and insert retaining pin into hitch pin.928. Adjust any lower link check chains, guide blocks, or sway blocks to prevent the mower from swaying side to side and possible contact with tractor rear tires.927. SETTING THE MOWER927.1 Setting Mower Height931. Park the tractor and mower on level ground.932. Using the 3-point hitch control lever, position the front of the mower with the side skids 1” less off the ground than desired cut height. For example, for a 3” cut, position the skids 2” from the ground. Set the 3-point control lever stop a...933. Shut down the tractor and remove the key.934. Level the mower deck front to rear by extending or retracting the 3-point top link.935. Level the mower side to side by manipulating one lower lift arm length. On most tractors, at least one of the lift arms is designed to allow for manipulation of its length. Shortening or extending will allow for deck leveling from side to side.936. Securely block up the mower at this height.937. Remove the bolts securing the tailwheel beam in position and allow the tailwheel to rest at ground level. Align tailwheel beam between nearest sets of holes in beam support brackets and reinstall support bolts on each side of beam. Tighten all bol...938. Extend the tractor’s top 3-point link so that when lifting the mower, the front of the deck will raise 2 to 2½" before the tail wheel leaves the ground. This will allow the mower to follow the contour of uneven terrain.937.2 Setting Deck Pitch949. Lower the Mower until the rear of the mower is resting securely on its tail wheel.9410. Slowly lower the 3-point lift arms further until the front of the mower is at least 3/4” lower than the rear of the mower.9411. Place the tractor’s 3-point control lever stop at this position so that each time the mower is raised and lowered the deck pitch will be maintained.948. DRIVELINE ATTACHMENT949.

NOTE: Snap ring must be inserted between bearing and gear before pressin...133SEAL INSTALLATION RECOMMENDATIONS1331. Check Seal - for damage that may have occurred prior to installation. A sealing lip that is turned back, cut or otherwise damaged should be replaced.1332. Check Bore - to see that leading edge is deburred. A rounded corner or chamber should be provided.1333. Check Shaft - remove surface nicks, burrs and grooves and lubricate with a hard, fibrous grease. NOTE: Wrap plastic tape around irregular shaft surfaces such as splines to protect seal during assembly.1334. Use Correct Installation Tool - Always use pipe or tube with approximate same OD as seal and press seal by striking tube.133DISASSEMBLY OUTPUT SHAFT (Mnt-R-0042)1341. Install slotted nut (Ref 18, Mnt-R-0040) onto shaft and then tap shaft end on solid surface to remove lower bearing and spacer.1342. Remove snap ring (Ref #7) and then repeat above procedure to remove upper bearing.1341. Assembly of output shaft is accomplished in exact reverse order. Install bearing over shaft and press up against bottom end of gear. Install snap ring (Ref. #7 Mnt-R-0040).1342. Install spacer and lower bearing on shaft. NOTE: Bearing Spacer (Ref #6) may be two different lengths and each spacer requires a different bottom cap.1341. Remove old seal from cap and press in new seal. (See SEAL INSTALLATION RECOMMENDATIONS).134MAIN GEARBOX1351. Remove bearing (Ref. #8 Mnt-R-0040) from inside main housing. A special slide hammer puller (PROTO No. 4056) or equal may be required to remove bearing. Press in new bearing using driving tube or pipe with approximate same OD. as bearing. Seat out...1351. Insert output shaft assembly into main housing and press into place.1352. Pre-lube lower bearing.1353. Place lower gasket in place and then carefully slide bearing retainer cap assembly down shaft.1354. Install bolts and lockwashers and torque to 40-50 ft. lbs.1351. Assemble three shims onto input shaft housing. Insert input shaft assembly into main housing by installing shaft end into bearing in main housing. It may be necessary to rotate shaft to align gear teeth so that housing will install completely.1352. Install washers and bolts and torque to 40-50 ft. lbs.1353. Gear backlash check procedure (Figure Mnt-R-0044). Install 1/2 x 3 capscrew through shear pin hole. Install flat washers to take up 1/2” space and then install nut and tighten so bolt cannot move.
