FIELD OPERATION
1. The mower works best on dry grass. Slower cutting speed and occasional cleaning may be required on
damp or wet grass.
2. The PTO must run at the full 540 rpm for a good cut. Slower speeds or double cutting could be required for
very high grass.
3. Use a higher blade setting for rough areas to prevent scalping of the surface.
4. Always cut counterclockwise so grass clippings are thrown on the grass already cut. This saves power and
wear on the blades.
5. Sharpen blades if grass tears instead of cutting cleanly.
6. Slow down when cutting corners. Turning too sharply on corners can leave
a small strip of grass uncut.
DISCONNECTING FROM TRACTOR
1. Park on a firm level area and clean the mower.
2. Lower the mower until the load is off the hitch arms.
3. Disconnect the hitch arms and the PTO shaft.
4. Cover the mower for storage to prevent rust.
MAINTENANCE
1. GEARBOX: The gearbox should be filled with SAE 90 oil to the bottom of level plug . Check the mower
before using and at regular intervals (approx. every 40 hours). See that this oil level is maintained.
2. GREASE: Grease wheel yokes, wheel bushing and PTO u-joints approximately every 8 hours. Before using
the mower for the first time, grease wheel bushings until you can see the grease squeezed out at the ends of
the wheel hub. Lubricate the telescoping PTO tube and the quick
release collars on the ends of the shaft about every 20 hours. Clean all grease fittings before injecting
grease and immediately replace any damaged or missing grease fittings. When using the safety chains
supplied with the PTO shaft, the shield bearings must be kept lubricated.
3. SHIELDING: Always keep all shielding in place and repair or replace if damaged.
4. BLADES: When replacing or grinding blades, all three blades must be replaced or reground at the same
time to maintain the proper balance in the cutting unit. Block up the mower securely before attempting to
remove the blades. Use heavy leather gloves to handle the blades. Be sure to tighten center bolt and lock
washer securely when replacing blades.
Always replace the lock washer with an extra heavy duty supplied with the spindle
5.BELTS: Remove the belt guards to check belt tightness. The center of the belt span should deflect about
10mm with nominal pressure. If the belts slip or are too loose, the bolts holding the gearbox must be
loosened.
Use the threaded tightener rod on the gearbox mount to tighten the belts. Lock the rod in place and re-
tighten the gearbox bolts when the belts are properly tightened. Replace belt guards. Changing belts follows
the same procedure as given in the preceding paragraph, except you will have to loosen the belts further to
remove them.
NOTE: Belts should always be replaced in matched sets.
