Securely attaching accessories, like collection systems or mulching kits, requires careful attention to the owner’s manual instructions. Ensure all bolts are tightened to the specified torque. Improper attachment can lead to operational issues or, more seriously, create a safety hazard during mowing. Double-check connections before each use, verifying stability and correct functionality of the added component.
Initial Setup and Adjustments
Before the first use, verify tire pressure matches specifications and adjust the cutting deck height to your desired level. Check all fluid levels – oil, fuel, and coolant – and top off as needed. Familiarize yourself with the controls and ensure the steering operates smoothly. A proper initial setup maximizes performance and longevity.
Operating Instructions
Proper operation involves safely starting and stopping the engine, utilizing effective mowing techniques, and adhering to all safety guidelines for optimal results.
Starting and Stopping the Engine
Before starting, ensure the blade is disengaged and the parking brake is set. Follow the specific starting procedure outlined in the owner’s manual, typically involving key insertion, choke adjustment (if applicable), and ignition.
To stop, disengage the blades, allow the engine to idle briefly, then turn the ignition key to the ‘off’ position. Always remove the key to prevent accidental starting.
Mowing Techniques for Optimal Results
For a clean cut, maintain a consistent speed and overlap each mowing pass by a few inches. Adjust the cutting height to suit your lawn’s needs, avoiding removing more than one-third of the grass blade length at a time.
Vary mowing patterns to prevent soil compaction and promote healthy grass growth. Regularly inspect the blade for sharpness and damage.

Maintenance Schedule
Regular upkeep ensures peak performance and longevity of your Craftsman 917. Follow the outlined tasks for seasonal and routine maintenance procedures.
Regular Maintenance Tasks
Consistent care is vital for a reliable Craftsman 917. This includes checking the engine oil level before each use, ensuring proper tire inflation, and cleaning the mower deck after every mowing session.
Additionally, inspect the blade for sharpness and damage, and lubricate moving parts as needed. Following these steps will help maintain optimal performance and prevent costly repairs.
Seasonal Maintenance Procedures
Preparing for storage is crucial. Before winter, stabilize the fuel or drain it completely to prevent gumming. Change the engine oil and filter, and inspect belts and hoses for wear. A full tune-up, including spark plug replacement, ensures a quick start next season. Battery removal and proper storage are also recommended.

Troubleshooting Common Issues
This section details solutions for engine problems, blade/deck concerns, and other frequent issues encountered with the Craftsman 917 lawn tractor.
