Cub Cadet PR-521 To Start Engine and Engage Blade, To Stop Engine and Blade, Using the Mulcher

To Start Engine and Engage Blade

WARNING: Never run engine indoors or in enclosed, poorly ventilated areas. Engine exhaust contains carbon monoxide, an odorless and deadly gas. Keep hands, feet, hair and loose clothing away from any moving parts on engine and lawn mower.

•Move throttle control lever to the fast (rabbit) position.

•Prime engine as instructed in the separate engine manual packed with your unit.

•Standing behind the unit, depress the blade control handle and hold it against the upper handle.

•Grasp starter handle and pull rope out slowly until engine reaches start of compression cycle (rope will pull slightly harder at this point). Let the rope rewind slowly.

•Pull rope with a rapid, continuous, full arm stroke. Keep a firm grip on starter handle. Return it slowly to the rope guide.

To Stop Engine and Blade

•Release the blade control handle to stop the engine and blade.

WARNING: The blade continues to rotate for a few seconds after engine is shut off.

•Disconnect the spark plug wire and ground it against the engine to prevent accidental starting while equipment is unattended.

Using Your Rotary Mower

WARNING: Never operate your unit without either the rear deflector or entire grass catcher assembly in place.

•Be sure that lawn is clear of stones, sticks, wire, or other objects which could damage lawn mower or engine. Such objects could be accidentally thrown by the mower in any direction and cause serious personal injury to the operator and others.

•For best results, do not cut wet grass because it tends to stick to the underside of the mower, and could cause you to slip and fall. New grass, thick grass or wet grass may require a narrower cut.

•Adjust blade speed according to lawn condition.

•For a healthy lawn, never cut more than one-third of the total length of the grass at any one cutting. Lawn should be cut in the fall season as long as there is growth.

•This mower is designed to be operated at full throttle to give you the best cut and do the most effective job of bagging the cut grass.

WARNING: Extensive vibration of the mower during operation is an indication of damage. If you strike a foreign object, stop the engine. Remove wire from spark plug, thoroughly inspect the mower for any damage, and repair the damage before restarting the mower.

Using the Mulcher

•For effective mulching, do not cut wet grass because it tends to stick to the underside of the deck, preventing proper mulching of grass clippings. New or thick grass may require a narrower cut. The ground speed should be adjusted to the condition of the lawn. If mowing has been delayed and the grass has been allowed to grow in excess of 4", mulching is not recommended. Mow using the grass bag (if so equipped) to reduce the grass height to 3-1/4" maximum before mulching.

SECTION 6: MAKING ADJUSTMENTS

WARNING: Do not at any time make any adjustment to lawn mower without first stopping engine and disconnecting spark plug wire.

Carburetor

WARNING: If any adjustments are made to the engine while the engine is running, keep clear of all moving parts. Be careful of heated surfaces around muffler.

Minor carburetor adjustments may be required to compensate for differences in fuel, temperature,

altitude and load. To adjust carburetor, refer to the engine manual packed with your mower.

NOTE: A dirty air cleaner will cause an engine to run rough. Be certain air cleaner is clean and attached to the carburetor before adjusting carburetor.

Cutting Height

An adjusting plate and thumb lever at each wheel position provides cutting height adjustment. Each adjusting plate has nine height positions.

•Simply depress the lever towards wheel and move wheel and lever assembly to desired position. All
