Usage Features
- Easy Adjustment: The dual knob bedknife-to-reel adjustment system simplifies the process of achieving optimal cutting performance. Each click of the adjusting screw moves the bedknife 0.0007 inches closer to the reel.
- Height of Cut Setting: The height of cut is precisely set using a gauge bar, ensuring consistency across the entire cutting unit. The rear roller bracket position can be adjusted for different HOC ranges (1/16 to 1/4 inch or 1/8 to 1 inch).
- Cut-Off Bar Adjustment: The cut-off bar can be adjusted to ensure clean clippings discharge, with specific settings for dry or wet turf conditions. It should be parallel to the reel for optimum performance and adjusted after reel sharpening.
- Versatile Mounting: Cutting units can be configured for different positions on the Greensmaster 3250-D traction unit by relocating the drive coupler and counterweight.
- Daily Adjustments: Operators are instructed to check bedknife-to-reel contact daily by slowly rotating the reel in reverse and adjusting the bedknife until light contact is felt and heard. This maintains sharp cutting edges and reduces the need for backlapping. Light contact is preferred to prevent accelerated wear and uneven cutting.
Maintenance Features
- Bedbar Servicing: The manual provides detailed instructions for removing and assembling the bedbar, including torque specifications for bolts and proper washer placement.
- Backlapping: Instructions for backlapping the reel are included, emphasizing safety precautions such as staying away from the reel and using a long-handled paint brush. Additional resources like the Toro Sharpening Reel & Rotary Mowers Manual (Form No. 80-300PT) are referenced for more detailed procedures.
- Burr Removal: After backlapping, running a file across the front face of the bedknife is recommended to remove any burrs or rough edges, improving the cutting edge.
- Ridge Filing: Over extended use, a ridge may develop at the ends of the bedknife. Operators are advised to round off or file these notches flush with the cutting edge for smooth operation.
- Warranty: The product comes with a two-year or 1500 operational hours limited warranty covering defects in materials or workmanship. It outlines owner responsibilities for maintenance and adjustments, as well as conditions not covered, such as non-Toro replacement parts, abuse, or normal wear and tear. An engine emissions warranty may also apply separately.
