Caster Wheels; Zt-3100 Powertrain - Husqvarna 97046770100 Operator's Manual

MAINTENANCE

Caster Wheels

Check every 200 hours. Check that wheels rotate
freely. Foam filled tires or solid tires will void the
warranty.
To replace, remove nut and caster bolt. Pull the
wheel out of the yoke and take care with the
spacer. Reinstall in reverse order. Tighten the
caster bolt and torque to 45 ft-lbs (61 Nm).
NOTE: Tire must rotate freely but axle spacers
must not. If wheels do not rotate freely take the
unit to the dealer for service.

ZT-3100 Powertrain

Regular external maintenance of the ZT-3100
Powertrain™ should include:
1. Check oil level in expansion tanks. When
the engine is cold, the tanks should be at the
FULL COLD level.
2. Inspect the vehicle drive belt, idler pulley(s),
and idler spring(s). Insure that no belt slippage
can occur. Slippage can cause low input
speed to the transmission.
3. Inspect the transmission cooling fan
for broken or bent blades. Remove any
obstructions such as grass clippings, leaves
or dirt.
4. Inspect the park brake and vehicle linkage to
insure proper action and adjustment of the
parking.
5. Inspect the vehicle control linkage to the
directional control arm on the transaxle.
Also, make sure the control arm is securely
fastened to the trunnion arm of the transaxle.
6. Inspect the bypass mechanism on the
transaxle and unit linkage to make sure it
rotates and releases fully.
IMPORTANT INFORMATION Any servicing
dealer attempting a warranty repair must have
prior approval before conducting maintenance
of a Hydro-Gear® product, unless the servicing
dealer is a current Authorized Hydro-Gear
Service Center.
Cleaning
Regular cleaning and washing, especially under
the mower deck, will increase the machine's life-
span. Make it a habit to clean the machine directly
after use (after it is cooled), before the dirt sticks.
Do not spray water on the top of the mower deck.
Use compressed air to clean the top side of
mower deck. Regularly clean deck and underside
of the deck with normal water pressure. Do not
use a high pressure washer or steam cleaner.
Avoid spraying engine and electrical components
with water.
Do not rinse hot surfaces with cold water. Let unit
cool before washing.
CAUTION! Always wear eye
protection when cleaning and
washing.
Hardware
Check daily. Inspect the entire machine for loose
or missing hardware.
