ATTACHMENTS

This unit can use many different attachments. See the attachment

page in this book. This unit can pull attachments like a lawn

sweeper, a lawn aerator, a hopper spreader or a small trailer. This

unit can not use attachments that engage the ground like a plow, a

disk harrow, or a cultivator.
For all pull-behind attachments or trailers, the maximum gross

weight is 250 pounds. Gross weight is the weight of the attachment

or trailer and any load that might be on or in it.

Do not operate on a slope that is greater than 10 degrees when

using a pull-behind attachment or trailer. We have included a slope

guide in this book to help you determine the slope on which you will

be operating your unit. Never allow someone to stand or ride on or

in an attachment or trailer.

ELECTRICAL SAFETY SYSTEM

The electrical system has two primary components, an Operator

Presence System and a Select Reverse

t

 system.

Operator Presence System (Seat)

The seat has an Operator Presence System to shut off the engine

when the operator leaves the seat. This system is not intended for

regular use in stopping the engine or the blade(s). Before leaving the

seat, move the blade rotation control to the DISENGAGE position,

shift to neutral, set the parking brake and stop the engine.

Select Reverse

t

 System

The 

Select Reverse

t

 system will allow the mower blade(s) to

continue to rotate when traveling in reverse. See “How To Operate

The Ignition Key Switch” and “How To Start The Engine” for further

details.

HOW TO OPERATE THE IGNITION KEY SWITCH

Use the ignition key switch to start and stop the engine. When you

start the engine and release the ignition key, the ignition key switch

will automatically default to the recommended RUN-MOW position

for normal mowing.

START -

Use this position to start the engine.

RUN-MOW - 

When you start the engine and release the ignition

key, the ignition key switch will automatically default to the

recommended 

RUN-MOW 

position for normal mowing. In the

RUN-MOW 

position, the system will stop the engine and the

blade(s) when the speed control pedal/shift lever is put in the

reverse position.

SELECT REVERSE

t

 - 

The optional 

Select Reverse

t

position will allow the mower blade(s) to continue to rotate when

traveling in reverse. Always go back to the recommended

RUN-MOW position for normal mowing when operation in 

Select

Reverse

t

is not absolutely necessary. NEVER use the 

Select

Reverse

t

option if children are on or near the property.

WARNING: Operators are strongly discouraged

from using this option unless the operator de-

cides such operation is absolutely necessary and

that safe precautions are taken. Never use the Select Re-

verse

t

 option if children are on or near the property. Always

look down and behind before and while backing. After using

the Select Reverse

t

 position, move the ignition key back to

the RUN-MOW position.

STOP - 

Use this position to stop the engine.

HOW TO USE THE THROTTLE CONTROL

Use the 

throttle control

 to increase or decrease the speed of the

engine.

CAUTION: Always operate the engine with the throttle control

in the FAST position. If the engine runs for several minutes at

slower than the FAST position, the engine and transmission

will overheat and can be damaged.

1. Move the 

throttle/choke control

 completely forward to the

CHOKE 

 position to start a cold engine.

2. The FAST position is marked with a detent. For normal opera-

tion and when using a grass bagger, move the 

throttle control

to the FAST position. For maximum charging of the battery and

for a cooler running engine and transmission, operate the en-

gine in the FAST position.

3. For transport and to tow pull behind attachments, move the

throttle control to the SLOW position.

4. The engine governor is set at the factory for maximum perform-

ance. Do not adjust the governor to increase the speed of the

engine.
