HOW TO USE YOUR TRACTOR TO SET THE PARKING BRAKE

Your tractor is equipped with an operator presence-sensing switch. When the engine is running, any attempt by the operator to leave the seat without first setting the parking brake will shut off the engine.

Depress clutch/brake pedal (B) all the way down and hold.
Pull the parking brake lever (C) up and hold, release pressure from clutch/ brake pedal (B), then release the parking brake lever. The pedal should remain in the brake position. Make sure the parking brake will hold the tractor secure.

STOPPING

MOWER BLADES

- To stop the mower blades, move attachment clutch clutch lever to the disengaged position
- Attachment Clutch Position Engage Position
- Disengaged Clutch Position

GROUND DRIVE

To stop the ground drive, depress the clutch/ brake pedal all the way down.
Move the motion control lever (J) to the neutral position.
ENGINE –
Move throttle control (D) between half and full speed (fast) position.
NOTE: Failure to move throttle control between half and full speed (fast) position, before stopping, may cause the engine to “backfire”.
Turn the ignition key (F) to the “STOP” position and remove the key. Always remove the key when leaving the tractor to prevent unauthorized use.
Never use choke (N) to stop the engine.
IMPORTANT: Leaving the ignition switch in any position other than “STOP” will cause the battery to discharge and go dead.
NOTE: Under certain conditions when tractor is standing idle with the engine running, hot engine exhaust gases may cause the “browning” of grass. To eliminate this possibility, always stop the engine when stopping the tractor on grass areas.
CAUTION: Always stop the tractor completely, as described above, and set the parking brake before leaving the operator’s position.

TO USE THROTTLE CONTROL (D)

Always operate the engine at full speed (fast).

Operating the engine at less than full speed (fast) reduces the engine’s operating efficiency.
Full speed (fast) offers the best mower performance.

TO USE CHOKE CONTROL (N)

Use choke control whenever you are starting a cold engine. Do not use it to start a warm engine.
To engage choke control, pull the knob out. Slowly push the knob in to disengage.

TO MOVE FORWARD AND BACKWARD

The direction and speed of movement is controlled by the motion control lever. (J)

Start tractor with motion control lever in neutral (N) position.
Release parking brake.
Slowly move motion control lever to desired position.

TO ADJUST MOWER CUTTING HEIGHT

The position of the attachment lift lever (A) determines the cutting height.

Put attachment lift lever in desired cutting height slot.
Slide pointer tab (T) to desired cutting height as a reminder for next time youmow.
The cutting height range is approximately 1″ to 4″. The heights are measured from the ground to the blade tip with the engine not running. These heights are approximate and may vary depending
upon soil conditions, height of grass and types of grass being mowed.
The average lawn should be cut to approximately 2-1/2 inches during the cool season and to over 3 inches during hot months. For healthier and better looking lawns, mow often and after moderate
growth.
For best cutting performance, grass over 6 inches in height should be mowed twice. Make the first cut relatively high;the second to desired height.

TO ADJUST GAUGE WHEELS

Gauge wheels are properly adjusted when they are slightly off the ground when mower is at the desired cutting height in operating position. Gauge wheels then keep the deck in proper position to help prevent scalping in most terrain conditions.
NOTE: Adjust gauge wheels with tractor on a flat level surface.

Adjust the mower to the desired cutting height (See “TO ADJUST MOWER CUTTING HEIGHT” in this section of the manual).
With the mower in desired height of cut position, gauge wheels should be assembled so they are slightly off the ground. Install gauge wheel in the appropriate hole. Tighten securely.
Repeat for all, installing gauge wheel in same adjustment hole.

TO OPERATE MOWER

Your tractor is equipped with an operator presence-sensing switch. Any attempt by the operator to leave the seat with the engine running and the attachment clutch engaged will shut off the engine. You must
remain fully and centrally positioned in the seat to prevent the engine from hesitating or cutting off when operating your equipment on rough, rolling terrain or hills.

Select the desired height of the cut with the attachment lift lever.
Start mower blades by engaging the attachment clutch control.

TO STOP MOWER BLADES – disengage attachment clutch control.
CAUTION: Do not operate the mower without either the entire grass catcher, on mowers so equipped, or the deflector shield (S)in place.

REVERSE OPERATION SYSTEM (ROS)

Your tractor is equipped with a Reverse Operation System (ROS). Any attempt by the operator to travel in the reverse direction with the attachment clutch engaged will shut off the engine unless ignition key
is placed in the ROS “ON” position.

WARNING: Backing up with the attachment clutch engaged while mowing is strongly discouraged. Turning the ROS “ON”, to allow reverse operation with the attachment clutch engaged, should only
be done when the operator decides it is necessary to reposition the machine with the attachment engaged. Do not mow in reverse unless absolutely necessary.

USING THE REVERSE OPERATION SYSTEM –

Only use if you are certain no children or other bystanders will enter the mowing area.

Move motion control lever to neutral (N) position.
With engine running, turn ignition key counterclockwise to ROS “ON” position.
Look down and behind before and while backing.
Slowly move motion control lever to reverse (R) position to start movement.
When use of the ROS is no longer needed, turn the ignition key clockwise to engine “ON” position.

Engine “ON” Position (Normal Operating)

TO OPERATE ON HILLS

WARNING: Do not drive up or down hills with slopes greater than 15 ° and do not drive across any slope. Use the slope guide provided at the back of this manual.

Choose the slowest speed before starting up or down hills.
Avoid stopping or changing speed on hills.
If stopping is absolutely necessary, push clutch/brake pedal quickly to brake position
and engage parking brake.
Move motion control lever to neutral (N) position.
IMPORTANT: The motion control lever does not return to neutral (N) position when the clutch/brake pedal is depressed.
To restart movement, slowly release parking brake and clutch/brake pedal.
Slowly move motion control lever to slowest setting.
Make all turns slowly.
TO TRANSPORT
