Adjusting the Mowing Speed

The machine is adjusted at the factory, but speed may be
varied if desired.
1. Loosen jam nut on pedal lock capscrew (Fig. 53).

2. Rotate capscrew clockwise to increase mowing speed
and counterclockwise to decrease mowing speed.
3. Tighten jam nut and check ground speed. Readjust, if
required.
Adjusting the Cutting Unit
Lift/Drop
The cutting unit lift/drop circuit is equipped with a flow
control valve (Fig. 54). This valve is preset at the factory at
approximately 3 turns open, but an adjustment may be
required to compensate for differences in hydraulic oil
temperatures, mowing speeds, etc. If an adjustment is
required, proceed as follows:

Note: Allow the hydraulic oil to reach full operating
temperature before adjusting the flow control valve.
1. Raise the seat and locate the flow control valve for the
center pull frame (Fig. 54) which is located next to the
hydraulic manifold.
2. Loosen the set screw on the adjusting knob on the flow
control.
3. Rotate the knob 1/4 turn counterclockwise if the center
cutting unit is dropping too late or 1/4 turn clockwise if
the center cutting unit is dropping too early.
4. After the desired setting has been achieved, tighten the
1
set screw.

Adjusting the Lift Cylinders

To regulate the height of the front cutting units when in the
raised (transport) position, the front lift cylinders may be
adjusted.
1. Lower the cutting units to the ground.
2. Loosen the jam nut, on the clevis, of the cutting unit lift
cylinder that needs to be adjusted.
3. Disconnect the cylinder clevis from the lift arm.
4. Rotate the clevis until the desired height is attained.
5. Connect the cylinder clevis to the lift arm and tighten
the jam nut.

Servicing the Battery

Battery posts, terminals, and related accessories
contain lead and lead compounds, chemicals
known to the State of California to cause cancer
and reproductive harm. Wash hands after
handling.
Cleaning the Battery
Keep the top of the battery clean by washing it periodically
with a brush dipped in ammonia or bicarbonate of soda
solution. Flush the top surface with water after cleaning it.
Do not remove the fill caps while cleaning the battery.
If corrosion occurs at the terminals, disconnect the cables,
negative (–) cable first, and scrape the clamps and terminals
separately. Reconnect the cables, positive (+) cable first,
and coat the terminals with petroleum jelly.
The battery cables must be tight on the terminals to provide
good electrical contact.
