Install capscrew (B) and belt stop (C). Position belt stop 1/16" away from belt. 27. Rotate belt cover (D) rearward onto latch (E). Make sure that pulley capscrew (F) is tightened securely. NOTE: If latch does not fit into cover slot when rear edge of cover is in line with arm assy., adjust position by rotating latch. 13 Turbo Installation - 50" Mower Deck Figure 9. A.

A WARNING A Before raising cover, shut off engine, remove key and set parking brake. BEFORE OPERATION • Clear the lawn of all sticks, stones, wire and other debris which may be caught or thrown by the mower blades. • Clean tube with mild detergent (other products may damage tube). Inspection windows can be removed to be cleaned. Make sure windows are securely in place before operating. • Check grass condition. If wet, wait until later in the day. If grass is wet, plugging may occur. • For efficient bagging, air circulation under the mower deck, through the chute and into othe bag is very important. For this reason, you should remove grass and debris from underside of mower deck, discharge chute and inside cover screen. • The blower housing and tube should be removed for cleaning. Remove the tube by unlatching the lower clip from the blower housing. • If desired, the bags can be lined with 30 gallon trash bags for easy disposal. • Inspect the grass bags for wear or damage. Make sure that there is a snug fit between mower deck, blower housing, tubes and grass bag cover. OPERATION WITH TURBO Grass should be cut often, and not too short. If grass is too long or lush, it may be necessary to keep ground speed to a minimum or to cut only half the width to prevent clogging. If grass is too high, operate with mower in high cutting position. Cut the grass again in lower cutting position, if desired. To check if grass is flowing up tube, view tube through rear inspection window. Do not open cover with mower engaged. To check if grass bags are full, reach back and feel top of right bag (left bag will fill first), or view tube discharge through front inspection window in cover. If a large amount of cut grass is spilling out from under the deck, the tube may be plugged or grass bags are full. Shut off tractor, disengage PTO and allow all moving parts to stop before disconnecting tube. Always operate at full throttle speed. OPERATION WITHOUT TURBO For operation without the turbo, the deflector must be properly installed in the down position and retained by the spring latch. On 44" decks, the arbor pulley cover must be rotated into the correct operating position, over the latch. To remove turbo, reverse the installation steps. EMPTYING THE BAGS NOTE: Move the seat forward and tilt it up to allow cover to remain the “up” position when emptying bags. 1. Raise the cover. If a plastic liner was not used, unhook each bag and turn it upside down to empty it. 2. If plastic liner was used, first tie up the top of the liner. Then either pull the liner out, or tip the bag over to allow the liner to slide out. STORAGE 1. Clean the grass catcher thoroughly. 2. If metal parts are scratched, coat with paint or oil. 3. Store in a dry area. Hang the bags to dry. Always store away from moisture. 15 Standard Torque Specifications TORQUE SPECIFICATIONS FOR STANDARD MACHINE HARDWARE (Tolerance ± 20%) SIZE SAE GRADE #2 o SAE GRADE #5 SAE GRADE #8 in/lbs ft/lbs Nm. in/lbs ft/lbs Nm. in/lbs ft/lbs Nm. 8-32 19 2.1 30 3.4 41 4.6 8-36 20 2.3 31 3.5 43 4.9 10-24 27 3.1 43 4.9 60 6.8 10-32 31 3.5 49 5.5 68 7.7 1/4-20 66 7.6 8 10.9 12 16.3 1/4-28 16 8.6 10 13.6 14 19.0 5/16-18 11 15.0 17 23.1 25 34.0 5/16-24 12 16.3 19 25.8 27 34.0 3/8-16 20 27.2 30 40.8 45 61.2 3/8-24 23 31.3 35 47.6 50 68.0 7/16-14 30 40.8 50 68.0 70 95.2 7/16-20 35 47.6 55 74.8 80 108.8 1/2-13 50 68.0 75 102.0 110 149.6 1/2-20 55 74.8 90 122.4 120 163.2 9/16-12 65 88.4 110 149.6 150 204.0 9/16-18 75 102.0 120 163.2 170 231.2 5/8-11 90 122.4 150 204.0 220 299.2 5/8-18 100 136 180 244.8 240 326.4 3/4-10 160 217.6 260 353.6 386 525 3/4-16 180 244.8 300 408.0 420 571.2 7/8-9 140 190.4 400 544.0 600 816.0 7/8-14 155 210.8 440 598.4 660 897.6 1-8 220 299.2 580 788.8 900 1,244.0 1-12 240 326.4 640 870.4 1,000 1,360.0 NOTES 1.
