Simplicity 2691668-01 Regent S Parts Manual

To perform routine maintenance, regularly check the oil levels, clean or replace air filters, inspect the blades for sharpness, and ensure tires are properly inflated. Refer to the owner’s manual for detailed instructions.
If the tractor won't start, check the battery connections, ensure the fuel tank is not empty, and examine the spark plug for wear or damage. Ensure the mower deck is disengaged and the parking brake is set before starting.
Uneven cutting can be caused by dull blades, incorrect tire pressure, or an unlevel mower deck. Check and adjust these components, and ensure the blades are properly aligned and sharp.
It is recommended to change the oil after the first 5 hours of use and then every 50 hours of operation. Always use the type of oil specified in the manual.
To adjust the mower deck height, use the deck lift lever located on the side of the tractor. Move the lever to the desired cutting height position, ensuring it's locked into place.
For winter storage, clean the tractor thoroughly, remove any grass clippings, change the oil, add fuel stabilizer, and store the battery in a cool, dry place. Cover the tractor to protect it from dust and moisture.
To replace the blades, ensure the engine is off and the key removed. Raise the mower deck, use a wrench to remove the blade bolts, replace the blades with new ones, and secure them tightly.
Excessive vibration can be caused by imbalanced blades, loose bolts, or debris lodged in the mower deck. Inspect and clean the deck, check blade balance, and tighten all bolts securely.
If the transmission is not engaging, check the drive belt for wear or damage, ensure the controls are properly adjusted, and inspect the transaxle for any leaks or issues.
To improve fuel efficiency, regularly maintain the engine, keep the blades sharp, operate at optimal speed settings, and avoid overloading the tractor. Ensure the tires are properly inflated and the air filters are clean.
