Cub Cadet G 1236 service manual Initial Adjustments, To Start The Mower

INITIAL ADJUSTMENTS

1.Disconnect the spark plug wire.

2.Check that all nuts, bolts and screws are tight.

3.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" (See Figure 19 page 19). 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.

4.The tension of the transmission drive belt should be adjusted so that a five-pound pull between the engine traction drive pulley and the transmission drive pulley deflects the belt about 3/16". (See Figure 20 page 20)

5.The two drive wheel belts are self-adjusting.

6.The steering control rods on each side of the handle assembly should initially be adjusted so that there is about a 1/4" to 3/8” space between the rod and the bottom of the slot in the neutral latch lever with the latch in the drive position (See Figure 6.) To make this adjustment, remove the large hairpin from the swivel joint at the bottom of each steering control rod and thread the swivel joint up or down the rod as needed.

1/4” to 3/8”

7.The brake rods (above each drive wheel) should be adjusted so that when the steering/brake levers are squeezed and the mower is pulled backward, the brakes lock the drive wheels. The machine should roll freely when the neutral latch lever is in the neutral lock position. To adjust the brake rods, remove the large hairpin from the swivel joint at the top of each brake rod and thread the swivel joint up or down the rod as

needed.

8.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.

9.Lubricate all fittings listed in the maintenance section.
