Zt-3100 Powertrain - Husqvarna MZ 52LE Operator's Manual

MAINTENANCE
procedure, the mower deck drive belt must be
installed prior to leveling the deck.
1. Wear heavy gloves. Turn each outer blade tip
to align with the deck side-to-side.
2. Measure from the floor surface up to the
bottom of the blade tip on the discharge side
of the mower deck. Record this measurement.
Move to the opposite side; check that
measurement is the same. If adjustment is
required, loosen the locknut and adjust bolt
up until both side-to-side measurements are
equal. Retain measurement.
3. Turn both outer blades to align with the deck
front-to-rear. Reposition the rear mounting
bolts up or down until the rear blade tips are
positioned 3.175 mm to 12.7 mm higher in the
rear than the front blade tips.
4. Confirm measurements once again. The
blade tip height must be equal side-to-side. In
the rear, blade tips must be 3.175 mm to 12.7
mm higher 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.

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.
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.
