3.08 - Operating Techniques
All of the following factors are important in selecting the proper forward speed:
1. Height of grass.
2. Type of grass.
3. Density of grass.
4. Type of terrain.
5. Grass condition, wet or dry.
This mower has been designed to cut grass with heights from 4” to 8”. It is
recommended to avoid cutting grass taller than 10”. For the best results, try cutting the
grass at least once per week during growing season. Tall, dense grass should be cut at
low speed, while thin medium grass can be cut at a faster ground speed. For cleaner
cuts and efficient mowing, the blades must be kept sharp

.
Always operate PTO at 540 rpm. This is necessary to maintain proper blade speed and
obtain a clean cut.
Under certain conditions, tractor tires may roll some grass down and prevent it from
being cut at the same height as the surrounding area. If this occurs reduce the tractor
ground speed but maintain a 540 rpm engine speed. The lower ground speed will permit
the grass to at least partially rebound. Under some conditions grass will not rebound
enough to be cut evenly, resulting in an uneven appearance. In general, lower cutting
height gives a more even cut with less tendency to leave tire tracks. If cut is still not
satisfactory, cut the area twice.
Mow extremely tall grass twice. On the first pass use a high cutting height. On the
second pass position the mower at the desired height and, when practical, mow at a
right angle in travel to the first pass.
Plan your pattern to travel straight forward whenever possible. It is better to cut grass
more often, than too short. Short grass deteriorates rapidly in hot weather and invites
weed growth during growing season.
If at any time the mower should jam resulting in belt slippage of 2 or more seconds,
raise the mower and continue for 2-3 minutes. This will allow the pulleys to cool and
prolong belt life.
DANGER: The mower blades can throw objects hundreds of feet which could
result in personal or property damage.
Pick up all rocks and other debris before mowing.
Enter new areas carefully. Cut grass higher at first, allowing mower to clear
hidden objects.
CAUTION: For emergency reasons learn how to stop the tractor and mower
quickly. On the finishing mowers always disengage the PTO, lock parking brake,
