one hand is required to reposition the pins to pro-
vide 1/4" height-of-cut increments.
The mechanism includes: A hydraulic cylinder
that is used to raise the implement. A height
adjustment link and index provide predetermined
height for the implement - it is settable in 1/4"
increments; a lock position for the height adjust-
ment link settable by the pin in the highest (also
transport position) or lowest (also for mower deck
removal and installation).
The following features are incorporated into the
hydraulic actuated valve implement lift design:
Lever implement lift allows for some operators
with physical limitations to use the implement lift
mechanisms and the machine; reduces potential
for operator fatigue; accommodates a variety of
operator sizes, shapes, and strengths.
7. Fuel Shutoff Valve: (See Figure 7.) 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 Adjustment
Lever is located beneath the seat. The Seat Adjust-
ment Lever is used to move the seat forward and
backward. To place the seat in the desired position
pull the seat adjustment lever to the left then push
the seat forward or back to the desired position.
Release the lever so the seat will lock in place.
Note:
Please refer to Section G on pages 6 and 7
for more information regarding the Suspension
Seat
9. Digital Tachometer and Hour Meter: (See Figure
4) 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.
Note:
There will be a flashing "LUBE" for each
recommended lubrication interval. There is a flash-
ing "OIL" at each recommended engine oil and fil-
ter change.
Fuel Shutoff Valve
10.Choke Lever: (See Figure 4) The Choke Lever is
located on the right instrument panel next to the
seat. The Choke Lever is operated manually. Hav-
ing 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:
The Tanks equipped with E.F.I. do not
have a choke control.
C.Initial Adjustments
1.
Check the fluid levels and tires:
Note:
These checks should be made daily,
before starting the engine.
a. Fuel: Using a good grade of unleaded, regular
gasoline (for a gasoline engine), fill the fuel
tank (beside the engine on the left or right side
of the mower). When the fuel reaches one
inch from the top of the tank, stop. DO NOT
OVERFILL. Space must be left for expansion.
b. Engine Oil: (Filled at the factory before ship-
ment.) Pull out the oil dipstick, wipe it off and
reinsert it. Pull it out again and read the oil
level. If it is below the operating range, add oil
through the fill tube using a funnel to bring it
up to the top of the operating range.
Note:
Gasoline Engine: Use SAE 10W30 or
SAE 10W40 engine oil, rated for service SJ. Shell
Rimula 15W40 is also recommended and provides
service SL and CI-4 plus.
c. Hydraulic Oil: (Filled at the factory before
shipment.) The hydraulic oil tank is located
beneath the operator's seat. Always wipe off
the area around the oil tank fill neck before
checking the oil level to prevent dirt from con-
taminating the oil. Remove the cap and make
sure the oil level is a 1/4" below the oil tank fill
neck. If the oil level is low, fill with Shell Rimula
15W40 or equivalent oil. Equivalent oil should
meet GM Allison C-4.
d. Tires: 10-12 psi Rear, 20-25 psi Front
Note:
New tires are overinflated in order to
properly seat the bead to the rim. The normal
working pressure for the traction tires is 10-12 psi.
The front wheels should be inflated to 20-25 psi.
2.
Check that all Nuts, Bolts and Screws are
Tight.
3. Check the tension of the deck drive belts.
a.
Remove the deck cover
b.
The tension of the deck drive belts are main-
tained by a spring mechanism that adjusts for
wear and stretch.
c.
Examine the belts for cuts, fraying, and
excessive wear. Replace if any of these are
detected.
d.
Replace the deck cover.
