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.

1. Depress clutch/brake pedal (B) all the way down and hold.
2. 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 (o)

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 

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

• 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.

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

TO ADJUST GAUGE WHEELS

Gauge wheels are properly adjusted when they are slightly off the ground when the mower is at the desired cutting height in the operating position. Gauge wheels then keep the deck in the proper position to help prevent scalping in most terrain conditions.
NOTE: Adjust gauge wheels with the 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).
• Remove retainer spring and clevis pin which secure each gauge wheel bar.
• Lower gauge wheels to ground. Raise gauge wheels slightly to align holes in bracket and gauge wheel bar and insert clevis pin. Gauge wheels should be slightly
  off the ground.
• Replace retainer spring into clevis pin.
• Be sure all gauge wheels are in the same setting.
  • IMPORTANT: BE SURE TO READJUST GAUGE WHEELS IF YOU CHANGE THE CUTTING HEIGHT OF THE MOWER DECK.

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 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.

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

ROS “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 the clutch/brake pedal quickly to the brake position and engage parking brake.
• To restart movement, slowly release the parking brake and clutch/brake pedal.
• Slowly move motion control lever to slowest setting.
• Make all turns slowly.

TO TRANSPORT

When pushing or towing your tractor, be sure to disengage the transmission by placing freewheel control in the freewheeling position. Freewheel control is located at the rear drawbar of tractor.

• Raise attachment lift lever to its highest position
• Pull freewheel control out and into the slot and release so it is held in the disengaged position
• Do not push or tow tractor at more than two (2) MPH
• To re-engage transmission, reverse above procedure.

NOTE: To protect hood from damage when transporting your tractor on a truck or a trailer, be sure hood is closed and secured to tractor. Use an appropriate means of tying hood to tractor (rope, cord, etc.).

MAINTENANCE

1. Change more often when operating under a heavy load or in high ambient temperatures.
2. Service more often when operating in dirty or dusty conditions.
3. Replace blades more often when mowing in sandy soil.
4. Not required if equipped with a maintenance-free battery.
5. Tighten front axle pivot bolt to 35 ft.-lbs. maximum. Do not overtighten

GENERAL RECOMMENDATIONS

The warranty on this tractor does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, an operator must maintain the tractor as instructed in this
manual. Some adjustments will need to be made periodically to properly maintain your tractor. At least once a season, check to see if you should make any of the adjustments described in the Service and Adjustments section of this manual.

• At least once a year you should replace the spark plug, clean or replace air filter, and check blades and belts for wear. A new spark plug and clean air filter assure proper air-fuel mixture and help your engine run better and last longer.

BEFORE EACH USE

• Check engine oil level.
• Check brake operation.
• Check tire pressure.
