BEFORE OPERATING MOWER

1. Read this manual and the manual covering the tractor very carefully. Be sure you are familiar with the safety precautions, controls and operating instructions.

2. Check the mower carefully to be sure it is properly installed.

CAUTION: NEVER operate the mower unless the deflector assembly and discharge guard are both fastened securely in place, (See Figure 6), or unless the vacuum collector adaptor is in place.

3. Check the condition of mower blades. Keep them sharp and in balance.

4. Clear the lawn of all sticks, stones, wire and other debris which may be caught or thrown by the mower blade.

5. Determine the best method of mowing according to the dimensions, terrain and obstructions of the lawn.

6. Be sure that mower is properly leveled and adjusted as previously outlined.

OPERATING THE MOWER

Refer to tractor part of manual for starting engine and tractor.

ENGINE SPEED

Engine speed should normally be operated at 2/3 to full throttle when mowing. When grass is wet or over 3 inches high engine should be run at full speed for best resu Its.

TRANSMISSION SPEED SELECTION

All forward speeds may be used for mowing under some conditions. The higher speeds should only be used in smooth level lawns with moderate to light grass crop. Always select a forward speed that is slow enough to assure that you can properly and safely control the tractor over the ground conditions encountered.

CAUTION: When operating the mower for first time put the transmission in low speed until you become acquainted with the controls and operation of the tractor and mower.

MOWING PATTERN

The size and type of area to be mowed determines the best mowing pattern to use. Obstructions such as trees, fences, and buildings must also be considered. In most cases, making one or two passes in a clockwise direction around the outside of the area to be mowed is advisable to keep cut grass off of fences, walks, etc. The remainder of the mowing should normally be done in a counter-clockwise direction so the clippings are dispersed on the cut area.

On moderate size, frequently mowed lawns where the grass is light, it is practical to mow in a clockwise direction so the grass clippings are thrown toward the center of the lawn and concentrated for easy pickup and removal.

MOWING TIPS

Most lawns should be mowed to keep the grass approximately two to three inches high. Best results are obtained by cutting often and not too short. To keep a green lawn, never mow more than one third off the height of the grass or a maximum of one inch in one mowing. For extremely tall grass, set the cutting height at maximum for the first mowing, then reset to the desired height and mow again. Allow the grass to grow to three inches, then cut off only the top inch.

On thick or springy grass or soft ground, the mower rollers may sink into the ground giving too low a cut. Adjust the cutting height to get the desired height of cut. For best appearance, grass should be cut in the afternoon or evening when it is free of moisture.

To transport the mower, disengage the PTO control to stop the rotation of the mower blades. Raise the mower to a safe height to clear any objects that the tractor may pass over while in transit.

NOTE: Do not operate mower in the "transport" or raised position.

CAUTION: DO NOT WORK around mower housing area until you are certain that the mower blades have stopped rotating.

  Heed the CAUTION SIGN and the SAFETY FIRST SIGN located on the mower housing. Make certain the discharge guard and deflector assembly are always in place before operating mower.

CAUTION: ALWAYS disconnect the power take off drive and stop engine before leaving the tractor seat. If leaving the tractor and mower unattended remove the ignition key.

BELTS

The mower drive belt and the arbor drive belt are specially constructed to insure proper operation and long life from the mower. The arbor drive belt is spring tensioned and requires no adjustment. Replace belts only with genuine replacement belts ordered from your dealer.
