Use Attachment Handle to lower mower into cutting position, Start mowing at stow speed and 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.
6.
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

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 a grinding 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 balance 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 most Sears Retail Stores=

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 tractor,. 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 a discharge when being operated,
