Initial Adjustments - Cub Cadet Commercial 1536H Operator's And Service Manual

B. INITIAL ADJUSTMENTS
1. Disconnect the spark plug wire.
2. Check the tire pressure. Drive Wheels should be inflated to 25 psi. Caster Wheels should be inflated to 15 psi.
Note: New tires are overinflated in order to properly seat the bead to the rim.
3. Check that all nuts, bolts and screws are tight.
4. Check the tension of the deck drive belts:
a. Remove the deck cover shield and engage the blade clutch.
b. Make sure the belts clear the belt guides by 1/8" to 1/4".
c. The tension of the deck drive belts should be adjusted so that a ten-pound pull between two pulleys
deflects each belt about 1/2". Do not overtighten these belts. The blade clutch should engage
with only moderate force.
d. Replace the deck cover shield and disengage the blade clutch.
5. The tension of the pump drive belt should be adjusted so that a five-pound pull between the engine traction
drive pulley and the pump drive pulley opposite the idler pulley deflects the belt about 3/16".
6. The long traction/steering control rods which run down to the pump control levers on each side of the handle
assembly should initially be adjusted so that when the ground speed control levers are in neutral and the
traction/steering levers are released from the neutral lock position, the mower stands still with the engine
running.
If the mower starts to creep forward or to the rear in this situation, then
control rod on the side of the mower which seemed to creep must be adjusted.
Loosen the top and bottom nut on the turnbuckle and adjust until the drive wheel stops moving. Then
retighten the top nuts.
The short traction/steering control rods which run down from the traction/steering levers on each side of the
handle assembly should initially be adjusted so that when the ground speed control levers are in neutral and
the traction/steering levers are in the neutral lock position, the mower stands still with the engine running. If
the mower starts to creep forward or to the rear in this situation, then the rod end bearing at the bottom of the
short control rod on the side of the mower which seemed to creep must be adjusted. Remove the hairpin
holding the long control rod in place in the rod end bearing, remove the flat washer and pull the long control
rod from the rod end bearing. Loosen the lock nut and adjust the rod end bearing ½ turn clockwise if the
creep was forward or ½ turn counterclockwise if the creep was to the rear. Tighten the lock nut, replace the
long control rod in the rod end bearing, replace the flat washer and the hairpin.
7. Adjusting the cutting height: The mower is shipped with the cutting height set at 3 inches ±1/4 inch
depending on the air pressure in the tires. To change the cutting height, blade spacers and/or caster spacers
must be moved according to the table on page 12.
8. Lubricate all fittings listed in the maintenance section.
