TRACTOR

Always observe safety rules when per- forming any maintenance.

BRAKE OPERATION

If tractor requires more than six (6) feet stopping distance at high speed in highest

gear, then brake must be adjusted. (See "TO ADJUST BRAKE" in the Service and

Adjustments section of this manual).

TIRES

Maintain proper air pressure in all tires (See "PRODUCT SPECIFICATIONS"

section of this manual).

Keep tires free of gasoline, oil, or insect control chemicals which can harm rub- ber.

Avoid stumps, stones, deep ruts, sharp objects and other hazards that may cause tire damage.

NOTE: To seal tire punctures and prevent flat tires due to slow leaks, tire sealant

may be purchased from your local parts

dealer. Tire sealant also prevents tire dry rot and corrosion.

OPERATOR PRESENCE SYSTEM

Be sure operator presence and interlock systems are working properly. If your trac- tor does not function as described, repair the problem immediately.

The engine should not start unless the

clutch/brake pedal is fully depressed and attachement clutch control is in the

disengaged position.

When the engine is running, any at- tempt by the operator to leave the seat without first setting the parking brake should shut off the engine.

When the engine is running and the attachment clutch is engaged, any at- tempt by the operator to leave the seat should shut off the engine.

The attachment clutch should never op-

erate unless the operator is in the seat.

BLADE CARE

For best results mower blades must be

kept sharp. Replace bent or damaged blades.

BLADE REMOVAL

1.Raise mower to highest position to al- low access to blades.

2.Remove blade bolt, lock washer and flat washer securing blade.

3.Install new or resharpened blade

with trailing edge up towards deck as shown.

TO SHARPEN BLADE

NOTE: We do not recommend sharp- ening blade - but if you do, be sure the blade is balanced.

Care should be taken to keep the blade balanced. An unbalanced blade will cause

excessive vibration and eventual damage to mower and engine.

The blade can be sharpened with a file or on a grinding wheel. Do not attempt to sharpen while on the mower.

To check blade balance, you will need a 5/8" diameter steel bolt, pin, or a cone balancer. (When using a cone balancer, follow the instructions supplied with balancer.)

NOTE: Do not use a nail for balancing blade. The lobes of the center hole may appear to be centered, but are not.

Slide blade on to an unthreaded portion of the steel bolt or pin and hold the bolt or pin parallel with the ground. If blade is balanced, it should remain in a horizontal position. If either end of the blade moves downward, sharpen the heavy end until the blade is balanced.

The Craftsman 917.273392 is a robust and versatile lawn mower designed to meet the needs of homeowners who value efficiency, performance, and convenience. This model combines power and user-friendly features to ensure an optimal mowing experience.

One of the standout features of the Craftsman 917.273392 is its powerful engine. Equipped with a reliable Briggs & Stratton engine, it delivers exceptional cutting performance, making it ideal for various lawn types and sizes. The engine’s overhead valve design enhances fuel efficiency and provides better torque.

The cutting deck is another impressive aspect of this lawn mower. It features a wide 42-inch cutting deck that allows for quicker mowing of large areas.

Safety is also a priority in the Craftsman 917.273392 design. The mower is equipped with a safety switch that automatically shuts off the engine when the operator leaves the seat, preventing accidents and enhancing peace of mind during operation.

Another valuable characteristic of this mower is its mulching capability. The optional mulching kit enables users to finely chop grass clippings, returning nutrients back to the soil, which can improve lawn health over time. The rear bagger option adds further versatility, allowing for efficient collection and disposal of grass clippings.

Maintenance has been made simpler with the inclusion of easy-access features. The mower deck can be easily cleaned without having to reach underneath, and regular maintenance tasks such as oil changes are straightforward.

Overall, the Craftsman 917.273392 combines power, versatility, and user-centric design elements, making it a reliable choice for homeowners looking to maintain a well-manicured lawn with ease.
