2. If oil level is low, add hydraulic oil to the reservoir
(Fig. 10); refer to Servicing the Hydraulic System,
page 44.
Filling the Fuel Tank
The engine runs on ASTM No. 2-D diesel fuel.
Danger
Under certain conditions, diesel fuel and fuel
vapors are highly flammable and explosive. A fire
or explosion from fuel can burn you and others
and can cause property damage.
• Use a funnel and fill the fuel tank outdoors, in
an open area, when the engine is off and is cold.
Wipe up any fuel that spills.
• Do not fill the fuel tank completely full. Add fuel
to the fuel tank until the level is 1 in. (25 mm)
below the bottom of the filler neck. This empty
space in the tank allows the fuel to expand.
• Never smoke when handling fuel, and stay away
from an open flame or where fuel fumes may be
ignited by a spark.
• Store fuel in a clean, safety-approved container
and keep the cap in place.
1. Remove fuel tank cap (Fig. 11).
2. Fill tank to about 1 in. (25 mm) below bottom of filler
neck with No. 2 diesel fuel. Install cap.

Checking the Tire Pressure
Since the machine can be operated under many different
types of turf conditions, proper tire pressure is very
important. Use the following as a guide:
Traction Unit Tires
• Under Normal mowing conditions and when used on a
• When turf is wet and softer than normal, use low
• When turf is dry and harder than normal, use higher tire
Castor Wheel Tires
• All conditions use 50 psi (340 kPa) castors.
Checking Systems Operation
Start engine. Move the machine, slowly, to an area where
the machine can be checked for proper function. Check
operation of controls, safety interlock system, engine,
hydraulic system, brakes and cutting units; refer to
Operation, page 23, for proper procedures.
Checking Cutting Unit
Mismatch
To ensure all cutting units are at the same height-of-cut:
1. Adjust all cutting units to the highest height–of–cut.
Note: Unless all castor wheel axles are not in the same
location, axles do not have to be relocated. All, however
must be in the same holes (Fig. 12).

faces fore and aft. Measure from plywood to front tip of
cutter blade and record dimension. All blade heights on
same deck should be within 1/4 in. (6.3 mm) of one
another. If blade heights meet criteria, proceed to step 5.
If blade heights are not within 1/4 in. (6.3 mm), proceed

underside to the top. By contrast, if end is to be raised,
transfer washer(s) from the top to the underside. Each
washer is 1/8 in. (3 mm) thick. Repeat measurement of
blade tip height and record new dimensions.
if necessary. If washers are transferred on a outboard
cutting unit castor arm, be sure to transfer the same
number on both ends of the castor arm.
Blade heights must be within 3/8 in. (9.5 mm) of one
another. If they are not, determine which cutting unit
