Electric Blade Clutch Switch: (See Figure 
1.) Located on the right side of the mower 
beside the ignition switch. This is an “on/off” 
push pull switch that controls the electric 
blade clutch which supplies power to the cut-
ting blades through the PTO. The switch must 
be cut off to start the engine and should be off 
for safety any time another person 
approaches the mower or the mowing deck is 
raised to the transport position. Power to the 
electric clutch will also be cut off if the opera-
tor leaves the operator’s seat.

5.

Parking Brake: (See Figure 3.) Located on 
the left side of the traction unit. The handle is 
an overcenter lever which applies the internal 
drum-type brake on each drive wheel when 
the handle is pulled to the rear. The brake 
must be engaged in order to start the engine.

6. Deck Lift Handle and Optional Foot Pedal 

Lift Assist: (See Figure 3.) Located on the 
right front corner of the mowing deck. Raise 
the mowing deck to the transport position, by 
pulling the lever to the rear and moving it 
inward into the stop for transport. To lower the 
mowing deck, pull the deck lift handle and 
move it outward. This lower’s the deck to the 
cutting position.The foot pedal lift assist (not 
pictured above) can provide “lift assist” to the 
hand lever or with “foot effort only”. To provide 
assistance to the lift handle: remove the hair-
pin clip from the locking pin and remove the 
pin from the pedal assembly. Fold the pedal 
down to the horizontal position so the hole in 
the pedal aligns with the hole in the lever. Re-
install the locking pin and hairpin clip. Pull on 
the Lift handle and depress the foot pedal to 
raise the deck. Lifting with “foot effort only” 
depress the foot pedal (the hand lever will lock 
into transport position if fully depressed). To 
release the lift mechanism depress the foot 
pedal, move the hand lever outward and 
slowly reduce foot pedal effort to lower the 

mechanism. To service the unit: Remove the 
hairpin clip from the locking pin and remove 
the pin from the pedal assembly. Fold the 
pedal up to vertical position so the hole in the 
pedal aligns with the hole in the lever. Rein-
stall the locking pin and hairpin clip. This is 
the required position for the foot pedal for the 
foot platform to tilt forward and to access 
some of the machines components.

7. Fuel Shutoff Valve: (See Figure 4.) Located 

on top of the fuel tank(s). When turned in a 
clockwise direction until it stops, it will shut off 
the flow of fuel to the engine. When turned in 
a counterclockwise direction it will open and 
allow fuel to flow to the engine. Close this 
valve if you are not going to run the mower for 
a period of 30 minutes or more to prevent 
flooding the engine.

8. Seat Adjustment Lever: The Seat Adjust-

ment Lever is located beneath the seat. The 
Seat Adjustment Lever is used to move the 
seat forward and backward. To place the seat 
in the desired position pull the seat adjust-
ment lever to the left then push the seat for-
ward or back to the desired position. Release 
the lever so the seat will lock in place.

9. Digital Tachometer and Hour Meter: (See 

Figure 1) Located on the right side of the 
mower in front of the ignition switch. When the 
machine is running the tachometer displays 
engine rpm. When the machine is off the 
tachometer displays running time.

10. Choke Lever: (See Figure 2) The Choke 

Lever is located on the left instrument panel 
next to the seat. The Choke Lever is operated 
manually. Having the Choke Lever in the ON 
position helps the engine to start during initial 
start-up. During normal operation the Choke 
Lever should be in the OFF position.

Note:

 

There will be a flashing “LUBE” for 

each recommended lubrication interval. There 
is a flashing “OIL” at each recommended 
engine oil and filter change. Reset after hour.
