Checking the Front-to-Rear Blade Slope
Check the front-to-rear blade slope any time you install the mower. If the front blade tip is not 1/8–1/4 inch (4–7 mm) lower than the rear blade tip, adjust the blade slope using the following instructions:
1. Park the machine on a level surface, disengage the
power take off (PTO), set the parking brake, and turn the ignition key to off. Remove the key.
2. Check and set the air pressure in the front and rear tires
to 12 psi (85 kPa).
3. Adjust height-of-cut lever on mower to the middle of
the range and lower attachment lift.
12.Route belt around V and flat pulleys and loop over
center mower spindle, top pulley.(Fig. 6).
13.Check that spacer is on shaft and install belt cover with
rod in hole. Secure with locknut (Fig. 6).
4. Carefully rotate blades so they are facing front and rear
(Fig. 7).

5. Measure between the tip of the front blade (Fig. 7) and
the tip of the rear blade to the flat surface. If the front blade tip is not 1/8–1/4 inch (4–7 mm) lower than the rear blade tip adjust rear adjustment link.

Cutting a Lawn for the First Time
1
Cut grass slightly longer than normal to ensure the cutting height of the mower does not scalp any uneven ground. However, the cutting height used in the past is generally the best one to use. When cutting grass longer than six inches tall, you may want to cut the lawn twice to ensure an acceptable quality-of-cut.

Cut 1/3 of the Grass Blade
It is best to cut only about 1/3 of the grass blade. Cutting more than that is not recommended, unless grass is sparse or it is late fall when grass grows more slowly.
Mowing Direction
Alternate mowing direction to keep the grass standing straight. This also helps disperse clippings which enhances decomposition and fertilization.
Mow at Correct Intervals
Normally , mow every 4 days. But remember, grass grows at different rates at different times. So to maintain the same cutting height, which is a good practice, mow more often in early spring. As the grass growth rate slows in mid summer, mow less frequently. If you cannot mow for an extended period, first mow at a high cutting height; then mow again 2 days later at a lower height setting.
Ground Speed
To improve cut quality, use slower ground speed.
Avoid Cutting Too Low
11. Slide the mower out from under the chassis to the the
right side.
Note: Save all hardware, washers and hairpin cotters for use when installing deck.
Tips for Mowing Grass
Fast Throttle Setting
For best mowing and maximum air circulation, operate the engine at fast. Air is required to thoroughly cut grass clippings, so do not set the height-of-cut so low, as to totally surround the mower by uncut grass. Always try to have one side of the mower free from uncut grass, which allows air to be drawn into the mower.
If the cutting width of the mower is wider than the mower you previously used, raise the cutting height to ensure uneven turf is not cut too short.
Long Grass
If the grass is ever allowed to grow slightly longer than normal, or if it contains a high degree of moisture, raise the cutting height higher than usual and cut the grass at this setting. Then cut the grass again using the lower, normal setting.
When Stopping
If the machine’s forward motion must be stopped while mowing, a clump of grass clippings may drop onto your lawn. To avoid this:
1. With the blade(s) engaged, move onto a previously cut
area.
11
2. To disperse the clippings evenly, raise the mower one or
two height-of-cut settings while driving forward with the blade(s) engaged.
Keep the Underside of the Mower Clean
Clean clippings and dirt from the underside of the mower after each use. If grass and dirt build up inside the mower, cutting quality will eventually become unsatisfactory.
Blade Maintenance
Maintain a sharp blade throughout the cutting season because a sharp blade cuts cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease. Every 30 days, check the cutter blade(s) for sharpness and file down any nicks.
Maintenance
Note: Determine the left and right sides of the machine from the normal operating position.

If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders.
Remove the key from the ignition and disconnect the wire from the spark plug(s) before you do any maintenance. Set the wire aside so that it does not accidentally contact the spark plug.

Caution
Servicing the Cutting Blades
To ensure a superior quality of cut, keep the blade(s) sharp. For convenient sharpening and replacement, you may want to have an extra blade(s).
Danger
A worn or damaged blade can break, and a piece of the blade could be thrown into the operator’s or bystander’s area, resulting in serious personal injury or death.
Inspect the blade periodically for wear or
damage.
Replace a worn or damaged blade.
12
Warning
A blade that is bent or damaged could break apart and could seriously injure or kill you or bystanders.
Always replace bent or damaged blade with a
new blade.
Never file or create sharp notches in the edges
or surfaces of blade.
3. Remove the nut, flat washer, blade and washer
(Fig. 20). A block of wood may be wedged between the blade and the mower to lock the blade when you are removing the bolt.
4. Inspect all parts. If damage is noticed, install new parts.

Inspecting the Blade(s)
Inspect the blades every 5 hours.
1. Remove the mower; refer to Removing the Mower,
page 10.
2. Carefully tip the mower over.
3. Inspect the cutting edges (Fig. 19). If the edges are not
sharp or have nicks, remove the blade(s) and sharpen them; refer to Sharpening the Blade(s), page 13.
4. Inspect the blade(s), especially the curved area
(Fig. 19). If you notice any damage, wear, or a slot forming in the area shown in Figure 19, immediately install a new blade.

Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of the
blade (Fig. 21). Maintain the original angle. The blade retains its balance if the same amount of material is removed from both cutting edges.

2. Check the balance of the blade by putting it on a blade
balancer (Fig. 22).
If the blade stays in a horizontal position, the blade
is balanced and can be used.
If the blade is not balanced, file some metal off the
back side of the blade. Repeat this procedure until the blade is balanced.

4. Connect a grease gun to the fitting. Pump grease into
the fittings.

(Fig. 23).
Important The curved part of the blade must be
pointing toward the inside of the mower to assure proper cutting.
2. Tighten the bland nut to 80-100 ft.–lb. (109-136 Nm).
