Anti-scalp Rollers
Anti-scalp rollers keep the deck in the proper position to help
prevent scalping in most terrain conditions. Do not adjust the
rollers to support the deck.
IMPORTANT INFORMATION Adjust anti-scalp rollers with
the mower on a flat level surface.
To avoid deck damage, the anti-scalp rollers must not be
adjusted to support the deck.
The anti-scalp rollers can be set in three positions:
• Upper position 1½" to 2½" (38 to 64 mm) grass
• Middle position 2½" to 4" (64 to 102 mm) grass
• Lower position 4" to 5" (102 to 127 mm) grass
The rollers should be approximately ¼" (6.5 mm) from ground.
Do not adjust the rollers to support the deck.
Caster Wheels
Check every 200 hours. Check that wheels rotate freely.
Removal and Installation
Remove nut and caster bolt. Pull the wheel out of the fork.
Install in reverse order. Tighten caster bolt. Torque to 45 ft-lbs
(61 Nm), then back nut off ½ turn.
NOTE: Tire should rotate freely but axle spacers should not.
If wheels do not rotate freely take the unit to the dealer for
service.
MAINTENANCE
ZT-3400 Powertrain
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.
Regular external maintenance of the ZT-3400 Powertrain™
should include the following:
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 park brake.
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.
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.
