4.4 DIESEL ENGINE BREAK-IN
The proper break-in of a new diesel engine can make a
difference in the performance and life of the engine. Perform
the following break-in procedure during the first 50 hours
of operation:
1. A new engine should be operated with as near full load
as possible. However, the engine must be allowed to
reach an operating temperature before operating at full
load conditions.
2. The engine oil should be checked twice daily. Higher
than normal oil consumption is not uncommon during
the initial break-in period.
3. Change the oil and filter element after the first 40
hours of operation.
4. Check all engine belts for proper tension after the first
10 hours of operation and adjust, if necessary. Refer
to Adjustments in Section 6.
5. During the break-in period, check and tighten all
engine hardware.
4.5 STARTING THE DIESEL ENGINE
4. Turn the ignition key switch to the PREHEAT position
until the indicator light for the glow plug glows bright
red. The colder the temperature, the longer it will take
to energize the glow plug. This step is not necessary
when starting a warm engine.
5. Turn the ignition key switch to START position and
release the key as soon as the engine starts. Do not
hold the key in the START position for more than 15
seconds at a time. Allow at least 60 seconds between
each cranking attempt to inhibit overheating the starter
motor. Prolonged cranking can damage the starter
motor and shorten battery life.
6. Allow engine to warm to operating temperature.
4.6 OPERATOR COMFORT ADJUSTMENTS
Two adjustments can be made to make your mowing job
comfortable. The steering handle can be adjusted up or
down and the seat can be adjusted forward or back.
A. Adjusting Steering Handle Height
1. Remove the hardware securing the handle to the
steering shaft. Two sets of holes are available to
adjust the handle height.

2. Move the handle to align with the other holes in the

Second Bolt Hole
1. Be sure the fuel shut-off valve is completely open.
The valve is located in the fuel line between the fuel
tank and electric fuel pump (See Section 7).
2. Sit in the operators seat and depress the interlock foot
pedal with your left foot. Make sure the parking brake
and mower blade brake are engaged.
3. Set throttle lever to 3/4 throttle.
DO NOT USE STARTING FLUIDS. Use of starting
fluids in the air intake system may be potentially
explosive or cause “Runaway” engine condition
that could result in engine damage and/or
personal injury.
