Dixon ZTR421 - Manual (Page 9)

CHAIN ADJUSTMENT
To adjust the drive chains, the body must be removed and shims
added behind the transaxle. Loosen 4 bolts which hold the
transaxle to the frame. Insert shims (Pt. No. 1541) as needed for
adjustment between transaxle and mount plates. Tighten the 4
bolts which hold the transaxle to the frame. A few drops of oil
periodically will lengthen chain life. Replace chain when rollers
become loose, chain breaks, or chain fails to operate properly.
WHEELS AND TIRES
Correct tire pressure is essential to the correct operation of the
machine. The correct pressure for the drive tires is 8 -10 Ibs.
The front tires should be inflated to 30-35 Ibs. Lug nuts should
be checked periodically.
ELECTRICAL SYSTEMS
Keep all connections clean and tight. Maintain the fluid in the
battery at correct level.
BODY
The body may be washed with a mild detergent and waxed with
any automotive type wax.
ENGINE
Follow the manufacturer's instructions as to maintenance and
repair.
TRANSAXLE
For adjustment or repair confer with authorized Dixon dealer
service department. Adjustment or repair by other than
authorized dealer voids warranty.
SERVICE LEGS
Service legs are located under the front end of the body of the
unit. These legs serve as additional weight for the front end of
the mower, and when lowered, give service access to the
mower deck without having to remove this assembly.
To lower these service legs:
1. Set parking brake.
2. Raise mower deck to top position.
3. For safety, support the service legs so that they will not fall.
Loosen and remove the four nuts and two bottom plates
from the U-bolts. Then remove the support and lower
service legs to ground.
4. Raise front end of unit and move the service legs into
position, spreading them as wide as possible to achieve
maximum stability.
