Anti-Scalp Rollers; Zt-3100 Powertrain - Husqvarna MZ 54S Operator's Manual

MAINTENANCE
than the front measurement. In the front,
blade tips must be equal from side-to-side.
NOTE: This will place the mower deck in a
standard measurement position. Depending on
the type of grass being mowed or environmental
conditions, more adjustments may be required to
get the desired cut.

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 1" to 2-1/2" grass
• Middle position 2-1/2" to 4" grass
• Lower position 4" to 5" grass
The rollers must be approximately 1/4" from
ground. Do not adjust the rollers to support the
deck.

ZT-3100 Powertrain

Regular external maintenance of the ZT-3100
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.
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.
IMPORTANT INFORMATION Any servicing
dealer attempting a warranty repair must have
