Engine oil filter and fuel filter

A 17.5-hp (13.0-kW), single-cylinder engine has plenty of power and torque to handle tough mowing, mulching, and bagging:

• Electronic ignition for fast starts
• Spring-return feature to ensure the operator will not mistakenly leave the throttle lever in the choke position
• Cast-iron cylinder liner for long engine life
• Overhead valves for excellent power and fuel economy
• Anti-vibration system
• Full-pressure lubrication and oil filter for cleaner oil, prolonging engine life, and extending the time between oil changes
  • More effective when operating the tractor on an incline
• Large fuel filter for trouble-free operation

No-tools oil drain valve

The no-tools oil drain valve is easy to access when changing engine oil.
