2. Allow the traction unit and muffler to cool completely.

3. Raise the seat and disconnect the negative battery

cable.

Warning

Battery terminals or metal tools could short
against metal machine components causing
sparks. Sparks can cause the battery gasses to
explode, resulting in personal injury.

• When removing or installing the battery cables,

do not allow the battery terminals to touch any
metal parts of the machine.

• Do not allow metal tools to short between the

battery terminals and metal parts of the
machine.

Removing the Spark Arrester

1. Allow the muffler to cool completely.

2. Loosen the clamp (Fig. 1).

3. Remove the spark arrester off the exhaust outlet

(Fig. 1).

1. Locate the upper heat shield below the exhaust

manifold (Fig. 2).

2. Check to make sure the shield is adjusted as far back

as possible (Fig. 2).

3. If there is a large gap, loosen the shield fasteners

(Fig. 2).

4. Slide the upper shield back as far as possible (Fig. 2).

5. Tighten the shield fasteners (Fig. 2).

Removing the Lower Air
Deflector and Heat Shield Bolts

1. If present remove and discard the lower air deflector

(Fig. 3). The lower air deflector is located under the
rear bumper.

Note: Determine the left and right sides of the machine
from the normal operating position.

1. Disconnect throttle and choke cables from the engine

control panel (back of engine) and pull the cables to
the front of the unit (Fig. 8).

2. Route both cables over the top of the right–hand

hydraulic pump and through the large opening behind
the right–hand pump (Fig. 5).

8. Adjust the throttle setting by pulling the throttle cable

until the throttle control plate rotates against the stop
on the engine control panel and tighten the throttle
cable clamp (Fig. 8).

9. Gently push the choke cable until the choke is fully

closed and tighten the choke cable clamp (Fig. 8).
Check to be sure the operator controls on the console
have not moved from the original settings in step 4.

Installing the Fuel Pump Heat
Shield and Vent Tube for
Kawasaki Engines

Note: The following instructions are for Kawasaki
Engines only.

Installing the Fuel Pump Heat Shield

1. Remove the 2 bolts that attach fuel pump to bracket

(Fig. 9).

5. Install the loom clip on the left–hand engine control

panel bolt as shown in figure 8. Rotate loom clip back
against control panel and tighten bolt (Fig. 8).

6. Route throttle and choke cables (now on left–hand side

of the engine) through the loom clip and connect to the
engine controls as shown in figure 8.

7. Move cable clamps from the original locations on the

engine control panel and loosely attach in the new
locations shown in figure 8.

Installing the Vent Tube

Important Inspect 17hp Kawasaki engines for this

style of vent tube. If there is a different type of vent tube;
refer to the Service Bulletin for Zero Radius Tractors
#LCE 38, September 20, 1999.

Note: The following instructions are for 19hp and 23hp
Kawasaki engines.

1. Remove vent tube from clamp (Fig. 10).
