7.8 DRIVE BELTS

All drive belts are spring-loaded and self-tensioning, however after the first 2, 4, 8 and 10 hours of operation, the belts should be checked for proper alignment and wear. Thereafter, check the belts after every 40 hours of operation or weekly, whichever occurs first.

- NOTE -

If you experience frequent belt wear or breakage, see your authorized Scag service center for belt adjustment.

7.9 CUTTER BLADES

A. Blade Inspection

1.Remove the ignition key before servicing the blades.

2.Raise the mower deck to the highest position. Place the lanyard pin in the highest cutting height position to prevent the cutter deck from falling.

WARNING

Always wear proper hand and eye protection when working with cutter blades.

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

B. Blade Sharpening

- NOTE -

If possible, use a file to sharpen the blade. Using a wheel grinder may burn the blade.

- NOTE -

DO NOT sharpen the blades beyond 1/3 of the width of the blade. See Figure 7-7.

1.Sharpen the cutting edge at the same bevel as the original. See Figure 7-7. 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.

C. Blade Replacement

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.

WARNING

Always wear proper hand and eye protection when working with cutter blades.

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 by pulling hard.

1.Remove the ignition key before replacing the blades.

2.Raise the mower deck to the highest position. Place the lanyard pin in the highest cutting height position to prevent the cutter deck from falling.

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. See Figure 7-8.

The STC52V-23BV and the STC52V-25CV-FR are both equipped with powerful V-twin engines that deliver dependable performance under tough conditions. These engines are designed to provide high torque, enabling users to tackle tougher mowing tasks without sacrificing speed or efficiency. With a cutting deck width of 52 inches, the STC52V models offer excellent maneuverability while providing ample coverage for large lawns.

On the other hand, the STC61V-23BV and STC61V-25CV models feature an impressive 61-inch cutting deck, making them ideal for larger properties. The wider deck allows for more efficient mowing with fewer passes, ultimately saving time and reducing operator fatigue. Both models also boast V-twin engines, ensuring robust performance that can handle dense grass and uneven terrain with ease.

One of the significant characteristics of the STC series is Scag's innovative Velocity Plus cutting deck technology. This unique design enhances airflow beneath the deck, resulting in superior grass cutting and improved discharge. The deck's aerodynamic shape not only ensures a clean cut but also allows for better grass collection in conjunction with optional bagging systems.

Additionally, all STC models are built with operator comfort in mind. Ergonomically designed controls, spacious seating, and intuitive instrument panels enable operators to work efficiently without discomfort during extended periods. These mowers also come standard with heavy-duty frames and high-quality components that offer durability and long-lasting performance, even in the most demanding conditions.

Another noteworthy feature across the STC lineup is the ease of maintenance. Scag Power Equipment has designed these mowers with accessible components, making it easier for users to perform routine maintenance tasks. This focus on practicality ensures that owners can keep their equipment in optimum condition with minimal effort.

In conclusion, the Scag Power Equipment STC52V-23BV, STC52V-25CV-FR, STC52V-25CV, STC61V-23BV, and STC61V-25CV represent the pinnacle of performance, comfort, and durability in the commercial mower sector. With powerful engines, advanced cutting technology, and a focus on user experience, these mowers continue to set the standard for excellence in outdoor power equipment.
