particle are abrasive to close-tolerance engine and hydraulic
assemblies.
Daily inspect mower for grass clippings and wire and
string tangles. The underside of the mower deck will collect
a build-up of grass clippings and dirt, especially when grass
is wet or has high moisture content. This build-up will
harden, restricting blade and air movement and will probably
show a poorer quality of cutting. Therefore it should be
removed routinely.
To do this it will be necessary to raise and block the deck,
using jack stands or blocks, in the full up position and scrape
the build-up from underneath. Refer to the deck owner's
manual for more detailed information.
Some repairs require the assistance of a trained service
mechanic and should not be attempted by unskilled
personnel.
Consult your Hustler service center when
assistance is needed.
Torque values
IMPORTANT:
WARNING: Particular attention must be given to
tightening the drive wheel lug bolts and blade spin-
dle bolts. Failure to correctly torque these items
may result in the loss of a wheel or blade, which
can cause serious damage or personal injury.
Torque values are given below:
Wheel (lug) bolts - front . . . . 85-95 . . . . . . 115-129
Wheel (lug) bolts - rear . . . . . 65-75 . . . . . . 88.1-101.7
Deck blade (top) bolts . . . . . . 65-75 . . . . . . 88.1-101.7
Deck blade (bottom) bolts . . . 118 . . . . . . . . 160.01
Lug bolts only - It is recommended that these be checked
after the first 2 hours of operation, initially, every 50 hours
and following removal for repair or replacement.
For all other torques refer to the various tractor parts
manuals for standard torque chart. See the Product Literature
section of this manual for ordering information.
For engine torque values, see engine service manual.
Tires
It is important that the tires have an equal amount of air
pressure. The recommended pressure are:
Front wheels. . . . . . . . . . . . 14-18 psi (96-124 KPa)
Rear wheels . . . . . . . . . . . . 14-18 psi (96-124 KPa)
Solid fill tires are not recommended for Hustler turf
equipment.
On any machine, with solid filled tires, the
warranty claim will be denied.

NOTE: Engine originally shipped with 10W-30 oil.
Lubrication fittings
NOTE: After every 50 hours of normal operation, apply a
good quality grease to the lubrication points listed below
(refer to the Recommended Lubricants chart). When operat-
ing under extremely dirty conditions, lubricate more fre-
quently than every 50 hours.
• Lift cylinder
• Front Lift arm
• Power Steering Cylinder
• Brake pedal shaft
• Differential Lock pedal shaft
To lubricate these points:
1. Wipe away all old grease and dirt from the lubrication
fittings to prevent dirt or foreign material from
entering as new grease is applied.
2. Use a high pressure grease gun to force in the new
grease. Apply pressure until clean grease oozes from
each lubrication point.
3. Wipe away any excess grease.
Service access
Opening the hood
WARNING: To avoid personal injury from contact
with moving parts:
Never open the hood and seat while the engine is
running.
Do not touch the muffler or exhaust pipe while they
are hot; severe burns could result.
Unlock the hood latch. Raise the hood using the hood
handle. Figure 4-1
Close the hood and clamp the hood latch.
Opening the seat platform
Pull out on the seat release knob and pivot the seat platform
forward. Figure 4-2
Electrical system
The electrical system is a 12-volt DC system with negative
ground.
The recommended battery size is a BCI group 35, 12-volt
battery with a minimum cold cranking ability of 490 amps at
-18°C (0°F). A maintenance-free battery is recommended.
Otherwise, follow battery manufacturer's maintenance,
safety, storing and charging specifications. Refer to
Maintenance Locator Chart found elsewhere in this manual.
