2-16 Final Checks

To check the operation of the safety interlock harness perform the following:

A. Start mower

B. While seated in the operator’s seat, rotate the engagement handle of the collection system away from the mower.

C. With the blower engaged, stand up from the operator’s seat. This action will shut off the mower which verifies proper installation of the harness.

SECTION III

OPERATING INSTRUCTIONS

3-1 General Safety

Only qualified people familiar with this operator’s manual and the mower’s operator’s manual should operate this machine.

3-2 Operation And Tips On Mowing

A. Perform BEFORE EACH USE maintenance list in paragraph 4-1.

B. Start mower.

C. With the mower at high idle speed, engage the mower deck.

D. While seated in the operator’s seat, rotate the engagement handle of the collection system away from the mower. Continue to rotate the handle until it stops in an over center position. With the blower engaged, you can proceed to operate the control levers of the mower.

NOTE: If the collection system does not appear to be collecting the grass clippings; disengage the deck, and blower, engage the parking brake and turn the mower off. Proceed to section 3-3, and review the section 2-9, in this manual.

To obtain the maximum effectiveness from your collection system the tips listed below should be followed:

*Watch your speed- Normal conditions will allow a speed of up to approximately 5 mph, but thick, heavy damp conditions will require reduced ground speed.

*Mow with sharp blades- A sharp blade cuts cleaner.

*Wet grass and leaves will decrease effectiveness and will increase horsepower requirements.

*Mow at higher cutting heights- Remove and mulch no more than 2” of grass length with each mowing. (Experts recommend not cutting off more than 1/3 of the grass blade length at any given time.)

*Mow twice, at different height settings, (high, then low), if grass is extra tall.

*Remember that horsepower requirements will vary with the mowing conditions such as type and height of turf grass, moisture content, amount of leaves, whether the terrain is flat or hilly, etc.

3-3 Disengagement Of The Blower

A. To disengage the blower, rotate the engagement handle towards the mower.

WARNING: The blower will continue to spin. DO NOT TOUCH the blower, pulleys, or the belt until the tractor is turned off. DO NOT adjust the belt tension until the mower is turned off. Refer to section 2-9 of the manual.

3-4 Unloading The Collection System

NOTE: Press the tab, located behind the operator’s left side, downward to feel if the collection system is full. If the container is full there will be resistance when depressing the tab.

A. Stop the forward movement of the mower. B. Disengage the mower deck.

C. Disengage the blower.

D. Verify that the dump area is clear.

E. Push the dump handle, on the left of the operator, away from the unit. While holding the handle pushed away, move the handle upward. The container door will swing upward and the container will rotate downward. The container will release its contents.

F. Once the contents of the container have fallen out, the container is ready to move back into its normal operating position. With the handle in the ‘away’ position, pull the handle downward until it stops. Move the handle towards the center of the mower. This motion will allow the latch to lock back into collection position.

NOTE: If you do not hold the handle away from the mower as you pull the handle downward, the latch will not lock and the container can unexpectedly release the contents collected.

SECTION IV

MAINTENANCE

4-1 Maintenance Checklist

Before each use:

1.Check blades and spindles to be sure that no foreign objects, such as wire or steel strapping bands, are wrapped around them.

2.Inspect blades for wear. Replace if necessary. If it is necessary to sharpen the blades, remove the blades from the spindles before sharpening. DO NOT sharpen blades while still attached to the mower.
