Usage Features

- Engine Speed Control: A lever allows the operator to set the engine speed to "Fast" (Rabbit) or "Slow."
- Blade Control: A lever on the handle engages and disengages the blade. Releasing this control stops both the engine and blade for safety.
- Rope Start Handle: For manually starting the engine.
- Engine Primer: Used to start a cold engine by pushing it three times. Not usually required for a warm engine.
- Handle Height Adjustment: The mower handle height can be adjusted by loosening lower nuts, moving the handle up or down, and retightening.
- Cutting Height Adjustment: Features front and rear height adjustment latches. All wheels should be set to the same cutting height. Notch 6 is the highest position, and Notch 1 is the lowest.
- Recycling Operation (Mulching): The mower is designed for recycling grass clippings. For best results, cut up to 1/3 of grass blade length when dry, with the engine speed on "FAST" and ground speed on "slowest." The front deck baffle should be in the highest position for mulching.
- Grass Catcher Installation (Optional Accessory): Allows for bagging clippings. The front deck baffle should be in the lowest position when using a grass bag.
- Discharge Deflector Installation (Optional Accessory): Can be installed to direct clippings.
Maintenance Features
The manual outlines a comprehensive maintenance schedule and procedures:
- Pre-start Checklist: Before each start-up, check guards, deflectors, grass bag, adapter, and covers; ensure blade and wheel drive controls work freely; check cutting height; check engine oil; add fuel; and clean exterior surfaces.
- Engine Oil Change: Recommended after the first 5 hours, then every 25 hours (or more often under heavy load/high temperatures). The manual describes how to drain oil through the dipstick tube by tipping the mower onto its lower handle (after draining the fuel tank).
- Transmission Grease Check: After the first 5 hours, then every 25 hours. Remove the fill plug, roll the machine to check if Snapper "00" grease is visible on the input gear, and add if needed.
- Mower Blade Check: Frequently inspect for sharpness, wear, and damage. Recommended torque for the blade retaining cap screw is 40 ft. lbs.
- Blade Sharpening: Sharpen at an angle of 22 to 28 degrees, ensuring not to sharpen beyond the original cutting edge. Balance the blade after sharpening.
- Blade Replacement: Replace if badly chipped, bent, out of balance, or cracked.
- Engine Drive Belt Check: Visually check for cracking, fraying, or exposed strands every 25 hours. Replace if worn or damaged.
- Transmission Poly-V Belt Check: Visually check for cracking, fraying, or exposed strands every 25 hours. Replace if worn or damaged.
- Annual Service: Perform all maintenance described in the "Service Schedule" section. This includes engine service (refer to engine owner's manual), air filter service, and engine oil service.
- Storage Procedure: Drain fuel from the tank and carburetor, disconnect and remove the spark plug wire, tape openings, clean the underside of the deck, lubricate exposed metal, and fold handles (on self-propelled models) before storing in a dry area.
- Wheel Drive Control Adjustment: Adjust clearance between the spring hook and clutch cable eye to 1/16" to 1/8" when released.
- Driven and Drive Disc Service: Clean discs if slippage occurs due to oil or grease. Reconnect or replace the drive spring if loose or broken.

- Rubber Driven Disc Replacement: Replace if badly chunked or worn.
- Driven Disc Bearing Replacement: Involves driving out the old bearing and installing a new one with retaining screws.
