Yard Machines 840 Thru 849 Stopping the Engine, Setting the Cutting Height, Operating the Tractor

Page 18

Slowly push in the choke as the engine warms up.

STOPPING THE ENGINE

Turn the ignition key to the left to the OFF position. Remove the key to prevent accidental starting.

IMPORTANT: If you strike a foreign object, stop the engine. Remove wire from spark plug, thoroughly inspect the unit for any damage, and repair the damage before restarting and operating the mower.

NOTE: If any problems are encountered, refer to the Trouble Shooting Guide.

SETTING THE CUTTING HEIGHT

Select the position for the tractor lift lever which gives the desired cutting height. Then move the wheels on the deck so that the wheels are 1/4 to 1/2 inch above the ground.

NOTE: To obtain the best, uniform cut, the deck is designed to be suspended from the tractor at the desired cutting height. The deck wheels or deck roller should be just off the ground, to smooth out the cut and guard against gouging.

OPERATING THE TRACTOR

Start the engine as instructed previously.

Move throttle control to full throttle to prevent strain on the engine and to operate attachments.

Place the shift lever in one of the two forward positions (LOW or HIGH), or in REVERSE. Place the speed control lever in desired position. Use first speed position when operating the tractor for the first time.

WARNING: Look to the rear before backing up.

Release the parking brake by depressing the clutch-brake pedal. Release clutch-brake pedal slowly to put unit into motion.

The tractor is brought to a stop by depressing the clutch-brake pedal.

The cutting blades (or other attachment) may be engaged while the tractor is moving or standing still. DO NOT engage the cutting blades abruptly as the sudden belt tension on the pulley may cause the engine to stall.

WARNING: Keep feet and hands away from the discharge opening, the blades or any part of the deck.

NOTE: When operating the unit initially, there will be little difference between the highest two speeds until after the belts have seated themselves into the pulleys during the break-in period. Be certain to change oil in the crankcase after the first 5 hours of operation.

Be sure that the lawn is clear of stones, sticks, wire, or other objects which could damage tractor or engine. For best results and to insure more even grass distribution, do not mow when lawn is excessively wet.

WARNING: Before leaving the operator’s position for any reason, disengage the blades, place the shift lever in neutral, engage the parking brake, shut engine off and remove the key.

When stopping the unit to empty a grass bag, etc., follow the instructions above. This procedure will also eliminate ‘‘browning’’ the grass, which is caused by hot exhaust gases from a running engine.

If unit stalls with speed control in sixth or seventh speed, or if unit will not operate with speed control lever in first or second speed position, proceed as follows.

Place shift lever in NEUTRAL.

Restart engine.

Place speed control lever in highest speed position.

Release clutch-brake pedal fully.

Depress clutch-brake pedal.

Place speed control lever in desired position.

Place shift lever in one of the forward positions (HIGH or LOW) or REVERSE, and follow normal operating procedures.

HIGH-LOW TRANSMISSION RANGES

HIGH range position is for normal load conditions, such as mowing or transporting.

LOW range position is for situations which require more torque when the tractor is used under high load conditions, such as tilling, snow removal or hauling heavy loads.

GRASS COLLECTOR AVAILABLE

GRASS COLLECTOR Model OEM-190-083 is available as optional equipment for tractors with 46" mowing decks.

WARNING: The mower should not be operated without the entire grass catcher or chute deflector in place.

NOTE: Under normal usage bag material is subject to wear, and should be checked periodically. Be sure to use only factory authorized replacement bag.
