Choke Knob (If equipped) - 
The choke knob is located on 
the left side of the mower next 
to the operator’s seat. Pull the 
knob out to choke the engine; 
push the knob in/down to open 
the choke. Having the choke in 
the “ON” position helps the engine to start during 
initial start-up. During normal operation the choke 
should be “OFF”.
MIL (If equipped) - The Multifunction Indicator 
Light (MIL) provides diagnostic information for the 
engine. If the MIL lights up and/or flashes see the 
service manual or contact your service center.
Parking Brake Lever
The parking brake lever is located to the 
left of the operator’s seat. When pulled up 
it engages the parking brake and when 
pushed down it releases the brake.

is engaged when engaging the parking 
brake, the engine will stop. The parking 
brake must be placed in the engaged 
position when starting the engine.
Fuel Tank Caps
The fuel tank caps are located on the top of the fuel 
tank on the left and right side of the seat. Turn the fill 
cap counter-clockwise to remove and clockwise until 
it clicks three times to tighten. Always re-install the 
fuel cap tightly onto the fuel tank after removing.
 WARNING
Never fill the fuel tank when the engine is running. If 
the engine is hot from recently running, allow to cool 
for several minutes before refueling. Highly flammable 
gasoline could splash onto the engine and cause a fire.

The deck height index consists of several holes 
located on the left of the foot platform. Each hole 
corresponds to a 1/4” change in the deck height 
position ranging from 1” at the lowest notch to 5” 
at the highest notch.
Deck Lift Pedal
The deck lift pedal is located on the right front 
corner of the foot platform, and is used to raise 
and lower the mowing deck.
To raise the mowing deck to the transport 
position, push the pedal all the way forward until 
the deck transportation lock snaps into position. 
To remove the deck from the transport position 
push forward on the deck lift pedal and pull up on 
the deck lock rod. To position the deck push the 
pedal all the way forward, remove the clevis pin, 
reinsert it in the desired cutting height and slowly 
release pressure on the pedal until you reach the 
clevis pin.
Transport Lock (Not shown)
The transport lock is located 
on the left side of the 
operator’s seat and is used to 
lock the deck in the transport 
position. Press down on the 
deck lift pedal and lift up on 
the deck lift release lever to 
release the deck.
Transmission Oil Expansion Reservoir 
(Not shown, if equipped)
The 500 series is not equipped with a transmission 
oil expansion reservoir, the 700 and 900 series 
are equipped with the transmission oil expansion 
reservoir. The transmission oil expansion 
reservoir is connected by hoses to the RH and LH 
transmission assemblies, and is located under the 
seat. The function of the reservoir is to hold the 
natural expansion of transmission oil that occurs as 
the transmission warms up during operation. DO 
NOT FILL THE RESERVOIR. 
Under normal operating conditions, no oil should 
be added to the reservoir. The COLD oil level 
should be approximately 1/4” above the bottom of 
the reservoir.
TRANSPORT  FLOAT
LOCK TRANSPORT
 
Note: Prior to the initial operation of the tractor, 
the oil level in the reservoir may be slightly higher 
than the maximum due to air in the oil lines. 
Operation of the tractor will eventually purge the 
air from the lines and the oil level will settle to 
the maximum.
Cup Holder
The cup holder is located between the fuel tank 
and the control panel to the right of the seat.
Roll Over Protective Structure (ROPS)
ROPS Positions
Refer to Figure 3-2 and the following descriptions 
and uses for the three (3) positions for the ROPS.
Transport Position
Transport with
Bagger Position
Operation Position
Figure 3-2
•  TRANSPORT: Only to be used when 
transporting the tractor or when they need 
to be momentarily folded-down to avoid 
contact with items such as tree limbs, clothes 
lines, guy wires, utility poles, buildings, etc.
•  TRANSPORT WITH BAGGER: Allows for the 
ROPS to be lowered for situations outlined 
for the TRANSPORT position when the tractor 
is equipped with a bagger.
•  OPERATION: The ROPS should always be 
in this position when operating unless 
the situations involved outlined in the 
TRANSPORT and TRANSPORT WITH BAGGER 
descriptions arise.
1.  To change the position of the ROPS, pull 
slightly up/push forward on the upper ROPS 
to relieve any tension on the locking pin 
(a) and rotate the locking pin (a) from the 
LOCKED (b) position into the ADJUSTMENT 
(c) position. Repeat the procedure for 
the locking pin on the opposite side. See 
Figure 3-3.
Figure 3-3
2.  Move the ROPS into the desired position. 
The three positions are TRANSPORT position, 
TRANSPORT WITH BAGGER position and 
OPERATION position. See Figure 3-2.
