CONTROLS

Become familiar with all of the controls and ad-

justments on the tractor and dozer blade before

operating. Refer to tractor ,_=,_ners manual for
tractor controls. Controls for Operating dozer

blade are as follows:

A. LIFT CONTROL LEVER:

Located on right hand side of tractor. See figure

28. Move lever forward to lower d_ozerblade. Pull

lever back to raise dozer blade, Pulling lever all

the way back locks dozer blade in up position.

ATTACHMENT

DEPTH CONTROL

KNOB

LEVER

C. Attachment depth control knob:

Adjust lift control lever movement with attachment
DEPTH CONTROL KNOB (see figure 28) for

maximum movement between locking notches
and to prevent lever from locking in the down lock

notch. See figure 28.

D. Blade angle handle and grip assembly:

Located on right hand side of tractor. See figure

28. NOTE: Always raise dozer blade and Ioc_

in "up" position before moving angle control
handle. Depress grip assembly to release blade

angle lock and push/pull angle control handle
forward to move dozer blade angle to left, center,

right and release grip to lock.

ADJUSTMENTS

A_

Blade angle lock bars.

If angle lock bars Do Not completely disengage

from slots in pivot plate assembly, adjustment of
cable is required. See figure 29.

B°

Adjust blade springs:

To change spring tension (stand in front of blade
assembly), adjust the nuts at the upper end of the
springs (see figure 29) turning counter clockwise

to relieve tension and clockwise to increase ten-
sion.

Adjust spring adjustment nuts approximately \
from end when moving snow or other light mate-

rial, (keep spring tension light for safety). This
frees the blade to spring trip and return if a hidden

obstacle is encountered.

Attachments That Add to the Usefulness of Your

Craftsman Tractor

Seats offers a wide variety of attachments that for your tractor. Many of these are listed below with brief

explanations of how they can help you.

Most of these attachments do not require additional hitches or conversion kits (those that do are indicated) and
are designed for easy attaching and detaching. You may order these attachments at most Sears retail stores,

catalog sales offices, and through the catalog.
