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.
FUEL TANK

Convenient fuel filler opening

The capacity is 2.4 U.S. gal. (9.1 L).
The fuel filler opening is conveniently located under the seat.

Filling the tank without spilling is easy.
A tethered fuel tank cap is more convenient.
The sealed fuel cap helps keep vapors inside the tank.

Frame made of full-length welded steel for reliability

Solid one-piece frame

 

Solid one-piece frame

The solid one-piece frame is constructed of 12-gauge, 0.105-in. (2.66-mm) steel:

Full-length, robotically welded frame design has high-strength steel rails for added strength and long life.
One-piece, steel fender deck is bolted to the frame.

CAST-IRON FRONT AXLE WILL NOT BEND

Front axle and wheel spindle

The front axle is constructed of solid cast iron that will not bend:

Automotive-like steering system with sector and pinion steering gears and single drag link with a tie rod provides a very strong, low-effort, and tight-turning system.
Three grease fittings, on both steering spindles and center pivot, allow for regular lubrication to help maintain easy steering and minimize wear.
Large, 0.75-in. (1.9-cm) diameter wheel spindles provide excellent durability.
