Anti-Scalp Rollers; Zt-3400 Powertrain - Husqvarna M-ZT 61 Operator's Manual

MAINTENANCE

Anti-scalp Rollers

Anti-scalp rollers are properly adjusted when they
are slightly off of the ground when the deck is at
the desired cutting height. 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.
Anti-scalp rollers can be set in three positions.
• Upper position 38 a 64 mm grass
• Middle position 64 a 102 mm grass
Lower position 102 a 127 mm grass
The rollers must be approximately 6.5 mm from
the ground. Do not adjust the rollers to support
the deck.

ZT-3400 Powertrain

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
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
