TO REPLACE MOWER BLADE DRIVE BELT (See Fig. 21)

The mower blade drive belt may be replaced without tools. Park the tractor on level surface. Engage parking brake.

BELT REMOVAL -

Remove mower from tractor (See “TO REMOVE MOWER” in this section of this manual).

To obtain the best cutting results, the mower housing should be adjusted so that the front is approximately 1/8" to 1/2" lower than the rear when the mower is in its highest position. Check adjustment on right side of tractor. Measure distance “D” directly in front and behind the mandrel at bottom edge of mower housing as shown.

Before making any necessary adjustments, check that

 

both front links are equal in length. Both links should be

 

approximately 10-3/8".

If links are not equal in length, adjust one link to same

 

length as other link.

Your tractor is equipped with an adjustable brake system which is mounted on the side of the transaxle.

If tractor requires more than six (6) feet stopping distance at high speed in highest gear, then brake must be adjusted.

Depress clutch/brake pedal and engage parking brake.

Measure distance between brake operating arm and nut “A” on brake rod.

If distance is other than 1-9/16", loosen jam nut and turn nut “A” until distance becomes 1-9/16". Retighten jam nut against nut “A”.

Road test tractor for proper stopping distance as stated above. Readjust if necessary. If stopping distance is still greater than six (6) feet in highest gear, further maintenance is necessary. Contact your nearest au- thorized service center/department.
