Use Attachment Handle to lower mower into cutting posi-

tion, Start mowing at stow speedand increase ground speed

by increasing throttle as conditions will permit,_ Average

cutting height is approximately 2 - I/2 to 2 -3/4 inches,

Height of cut can be adjusted by means of the Depth

Adjustment Knob (Fig, 25). Turn Depth Adjustment Knob

(clockwise ((_} or counterclockwise (f_,) to match pre-

selected Lift Control Lever mowing height.

Drive so that clippings are discharged onto the area that has

been cut. Have the cut area to the right of the machine°

This will result in a more even distribution of clippings

and more uniform cutting. When mowing large areas (Fig.

24), start by turning to the ;ight so that the clippings will

be discharged away from shrubs, fences, driveways, etc.

After two or three rounds, mow in the opposite direction

making left hand turns until f_nished. If grass is extremely

tall, it should be mowed twice. The first time cut relatively

high_ The second time to the desired helght, The left hand

side of mower should be used for trimming.

BLADE CARE

For best results mower blades must be kept sharp, The blades

can be sharpened with a few strokes of a file or on agrinding

wheel We suggest they be sharpened after every 15 hours of

mowing° Do not attempt to sharpen while on mower.

1. When grinding, care should be taken to maintain blade bal-

ance and the blade should be checked for proper balance

before reinstallation on mower_ Unbalanced or bent blade

will cause excessive vibration when running and eventual

damage to mower or engine° Replace bent or damaged

blades_

2. To ensure satisfactory operation, it is recommended that

before the start of each mowing season, the oldblades be

discarded and replaced with new blades. Mower blades can

be purchased at any Sears Service Center/Departments and

INSTRUCTIONS

To keep your tractor running better', longer; perform nec-

essary service using the following Maintenance Schedule.

Each time you start your tractor, check your Ammeter (Fig,

34), The needle should move towards the + (charging) mark

indicating the battery is being charged as you operate the trac-

tor,. The headlights wlll not show a discharge on the ammeter

because they are not connected to the battery (they have their

own electrical source, see page 26). If you have a lift motor

connected it wilt show adischarge when being operated,
