IMPORTANT: The engine starter should not be
operatedforperiods longerthen 30seconds ata time.
An interval of at least two minutes should be allowed
between such cranking periods to protect the starter
from overheating and burn-out.
5. Performtestto make sure safetystart interlocksystem
isoperating properly. Referto“Safety Start Interlock
System” on page 10.
6. As soon as engine begins to run, check to make
certain the oil warning light is off. If not, stop engine
immediately and check for the cause. Refer to
“Section 7 Troubleshooting” on page 37.
7. Allow the engine to idle a fewminutes before
advancing the throttle and/or engaging the blade
clutch.
8. Beforestopping the engine,place the control leversin
the brakeposition, disengage the blade engagement,
and throttle back to low idle for a couple of minutes;
then rotate ignition key counter-clockwise to the OFF
position. Remove the key from switch before leaving
the seat.
!
WARNING!
Never leave the machine unattended with key in ignition switch.
Moving Mower with Stalled Engine
Refer to Figure 2-7
Themower hydro-drives are equippedwith bypass valves
for moving the mower when the engine is inoperable. The
valve stems to the bypass valves are located near the top
of the hydraulic pumps and are identified as a hex stud.
Before moving the unit, turn each bypass valve stem
counterclockwise one-halfto onerevolution andplace the
control levers in neutral position.
Donot tow the machine.Move it by handor use a winchto
load it on a trailer for transporting.
When transporting on another vehicle, the tractor should
be facing forward and it must be secured.
IMPORTANT: Following repairs, always make certain
the two bypass valve stems are returned to their
operating position before running the mower.
Driving the Mower
!
DANGER!
Never make sudden stops or sudden reversing of direction,
especially when going down a slope. The steering is designed
for sensitive response. Rapid movement of the control levers in
either direction could resultin a reactionof the mower that can
cause serious injury.
Steering
Refer to Figure 2-8 on page 12
After starting engine, engage the control levers and steer
as follows:
• To Go Forward:
Push control levers forward an equal distance.
• To Go in Reverse:
Pull control levers rearward an equal distance.
• To Turn Left:
Move the right control lever farther forward from neutral
than the left control lever.
• To Turn Right:
Move the left control lever farther forward from neutral
than the right control lever.
• To Pivot Turn:
Move one control lever forward and the other control lever
back of neutral, this will allow the drive wheels to counterrotate.
Controlling the Speed
!
WARNING!
In the event of a system failure while mowing, engage both
parking brakes to stop or slow mower. Refer to Figure 2-5.

!
DANGER!
When going in reverse push forward gently on control levers
and avoid sudden movement. Any sudden movement could
cause the front of the mower to come off of the groundresulting
in possible loss of control.
To Stop or decrease speed:
Move control levers to neutral. When going forward pull
backgently on controllevers. When goingin reverse push
forward gently on control levers.
To Increase Speed:
Increase control levers equal distance from neutral. The
farther forward control levers are from neutral, the faster
the mower will travel forward. The farther back the control
levers are from neutral, the faster the mower will go in
reverse.

Operating Suggestions
!
DANGER!
Priorto operating the mower the operator should be thoroughly
familiar with the proper use and operation of the equipment,
should readthe manual completely and thoroughly, and should
haveattemptedslow moving maneuvers to become familiarwith
the operation of the equipment before attempting normal speed
operation.Aninexperiencedoperator should not mowon slopes
or on uneven terrain.
!
WARNING!
The mower’s control levers are very responsive: Easy does it!
For smooth operation, move lever slowly, avoid sudden
movement. Skill and ease of operation come with practice and
experience.
Inexperienced operators may have a tendency to
over-steer and lose control. Slow-moving practice
maneuvers are recommended to become familiar with
these characteristics before attempting normal speed
operation.
!
WARNING!
Sharpdepressionsor raised obstacles (suchas gutters or curbs)
should not be directly approached at high speed in an attempt
to jump them as the operator could be thrown from the mower.
Approach at a slow speed and angle one drive wheel at the
obstruction. Continue at an angle until the wheel clears and
then pivot the opposite wheel around.
When turning on soft wet turf, keep both wheels rolling
either forward or backward. Pivoting on one stopped
wheel can damage turf. This is especially important when
mowing.

Reverse Travel
Right Turn
Peakmowingperformance ismaintainedwhen thethrottle
is set at full rpm. This gives maximum power to the drive
wheels and deck when needed. Use the control levers to
control ground speed rather than engine rpm.
!
WARNING!
Do not operate the equipment while wearing sandals, tennis
shoes, sneakers, shorts or any type of loose fitting clothing.
Always wear long pants, safety glasses and safety shoes when
operating this machine.
Keepblades sharp. Manyproblems withincorrect cutting
patterns are due to dull blades or blades which have been
sharpened incorrectly. Information on sharpening blades
is listed in this manual’s maintenance section. In addition,
most communities have individuals or companies which
specialize in sharpening mower blades. Blade sharpness
should be checked daily.
Often professional mowing companies have an additional
set of blades and change blades twice a day: once in the
morning and again at noon.
Use high blade speed. Your Razor Pro is designed to
operate at full throttle. The throttle setting directly controls
bladespeed. The highest blade speed generally gives the
best cut.
Directgrass discharge awayfrom unmown area.Refer
to Figure 2-9 on page 13. Select a mowing pattern that
directsgrassdischarge awayfromuncut grass.Generally,
this means using a pattern utilizing left turns because
grassside dischargeis tothe right. Grass discharged onto
an unmowed area will be mowed twice. Mowing grass
twice puts an unnecessary load on the mower and
reduces mowing efficiency.
