Craftsman 917.28934 To Adjust Mower Cutting Height, • Put attachment lift lever in desired cut

TO ADJUST MOWER CUTTING HEIGHT

The position of the attachment lift lever (A) determines the cutting height.

• Put attachment lift lever in desired cut-

ting height slot.

The cutting height range is approximate- ly 1" to 4". The heights are measured from the ground to the blade tip with the engine not running. These heights are ap- proximate and may vary depending upon soil conditions, height of grass and types of grass being mowed.

The average lawn should be cut to ap- proximately 2-1/2" during the coot sea- son and to over 3" during hot months. For healthier and better looking lawns, mow often and after moderate growth. For best cutting performance, grass

over 6 inches in height should be mowed twice. Make the first cut rela-

tively high; the second to desired height.

TO ADJUST GAUGE WHEELS

Gauge wheels are properly adjusted when they are slightly off the ground when mower is at the desired cutting height in operating position. Gauge wheels then keep the deck

in proper position to help prevent scalping in most terrain conditions.

NOTE: Adjust gauge wheels with tractor on a flat level surface.

1.Adjust mower to desired cutting height (See "TO ADJUST MOWER CUTTING HEIGHT" in this section of manual).

2.With mower in desired height of cut posi- tion, gauge wheels should be assembled so they are slightly off the ground. Install gauge wheel in appropriate hole. Tighten securely.

3.Repeat for all, installing gauge wheel in same adjustment hole.

TO OPERATE MOWER

Your tractor is equipped with an operator presence sensing switch. Any attempt by the operator to leave the seat with the engine running and the attachment clutch engaged will shut off the engine. You must remain fully and centrally positioned in the seat to prevent the engine from hesitating or cutting off when operating your equip- ment on rough, rolling terrain or hills.

1.Select desired height of cut with at- tachment lift lever.

2.Start mower blades by engaging at- tachment clutch control.

TO STOP MOWER BLADES - disengage attachment clutch control.

_CAUTION: Do not operate the mower

without either the entire grass catcher, on mowers so equipped, or the deflector shield (S) in place.

REVERSE OPERATION SYSTEM (ROS)

Your tractor is equipped with a Reverse Operation System (ROS). Any attempt by

the operator to travel in the reverse direc- tion with the attachment clutch engaged will shut off the engine unless ignition key is placed in the ROS "ON" position.

_IbWARNING: Backing up with the at-

tachment clutch engaged while mowing is strongly discouraged. Turning the ROS "ON", to allow reverse operation with the attachment clutch engaged, should only be done when the operator decides it is necessary to reposition the machine with the attachment engaged. Do not mow in reverse unless absolutely necessary.
