7.8 DRIVE BELTS

After the first 2, 4, 8 and 10 hours of operation, check for proper tension on all drive belts and check for any damage. Thereafter, check the belt tension after every 100 hours of operation or bi-weekly, whichever occurs first.

1.Check the belts for cracks, tears, and excessive wear. Replace any damaged belts.

7.9 CUTTER BLADES

A. Blade Inspection

1.Remove the ignition key before servicing the blades.

2.Tilt the mower deck and secure in place.

WARNING:

Never operate the cutter blades with the deck in the raised position because it is hazardous and damage to mower will result.

3.Check the blades for straightness. If the cutter blades appear bent, they will need to be replaced.

B. Blade Sharpening

-NOTE-

DO NOT sharpen the blades beyond 1/3 of the width of the blade.

1.Sharpen the cutting edge at the same bevel as the original. See Figure 7-8. Sharpen only the top of the cutting edge to maintain sharpness.

2.Check the balance of the blade. If the blades are out of balance, vibration and premature wear can occur. See your authorized Scag dealer for blade balancing or special tools, if you choose to balance your own blades.

WARNING:

Do not attempt to straighten a bent blade, and never weld a broken or cracked blade. Always replace it with a new blade to assure safety.

4.If a blade cutting edge is dull or nicked, it should be sharpened. Remove the blades for sharpening. See "Blade Replacement."

-NOTE-

Keep the blades sharp. Cutting with dull blades not only yields a poor mowing job, but slows the cutting speed of the mower and causes extra wear on the engine and the blade drive.

C. Blade Replacement

1.Remove the ignition key and engage parking brake before replacing the blades.

2.Tilt the mower deck and secure in place with lock pin.

3.Secure the cutter blades to prevent them from rotating, (use the optional Blade Buddy tool, P/N 9212, to assist in securing the cutter blades), remove the nut from the blade attaching bolt. Remove the cutter blade, bolt and spacer from the spindle shaft.

4.To install the new blade, put the flat washer onto the blade bolt and slide the bolt into the hole in the cutter blade.
