BREAK-IN PERIOD Figure 3
As with a new car, your new HUSKY Tractor should
receive special attention. During the first few hours of
operation, it is best to vary the engine speed (see
inside front cover of engine manual) . . . . . . avoid full-
throttle driving . . . . and avoid quick starts and stops
until you have become well acquainted with your
tractor. IMPORTANT: THE TRACTOR IS SHIPPED
FROM THE FACTORY WITH OIL IN THE ENGINE
CRANKCASE. CHECK THE CRANKCASE AND THE
HYDROSTATIC TRANSMISSION OIL RESERVOIR
FOR PROPER OIL LEVEL BEFORE ATTEMPTING TO
START YOUR UNIT. BECOME FAMILIAR WITH THE
LOCATION OF EACH CONTROL. BE SURE
TRANSMISSION LEVER IS IN "PARK" POSITION.
Both the tractor and engine have been fully tested by
the factory and your dealer to assure your complete
satisfaction. Keep this manual available at all times,
read it carefully, if you have any questions that are not
answered in the manual, consult your Bolens dealer.
CONTROLS
Before operating the tractor, the operator should
become familiar with the function and location of each
control to ensure proper and efficient operation.
The following listed numbers and accompanying
information correspond to those numbers assigned to
the controls indicated in Figure 4.
1. Choke. Pull choke knob out to operate choke.
2. Ammeter. Indicates level of charge or discharge to or
from battery.
3. Light Switch. Pull light switch knob out to turn on
lights . . . . push in to turn lights off.
NOTE
Ignition-starter switch (4) must be ON to turn on head
and tail lights.
4. Ignition-Starter switch. Turn ignition switch against spring
tension to actuate starter. Release when engine starts.
5. Throttle. Pull throttle knob out one-half way for starting.
More or less throttle may be required due to grade of fuel and
temperature variations. Allow engine to warm up, then adjust
throttle to full engine R.P.M. while operating under load.
6. Foot Brake. Use when vehicle is being towed or freewheeling; when moving transmission lever (12) from
NEUTRAL or PARK position to DRIVE position.
7. Speed Control. Depress with toe of foot for forward motion.
Depress with heel of foot for reverse motion. Provides instant
braking and speed regulation. (See Figure 7.)
8. Speed Hold. Can be used to hold speed control (7) at a
desired speed setting. Depress with toe of left foot to hold,
and depress with heel of left foot to unlock. See Figure 6 for
operation of speed hold on page 5.
9. Depth Indicator Gauge. Allows operator to locate original
height or depth of attached implement.
10. Hydraulic Lift Lever. Push lever forward to raise and pull
lever back to lower attachments. Pull lift lever all the way back
for FLOAT position.
11. Power Take-Off (P.T.O.) Lever. Engages and disengages
power to attached implements. Lever positions indicated on
etched plate.
12. Transmission Lever. Place transmission lever in :
- NEUTRAL for towing .
- DRIVE for infinitely variable speeds from 0-8 mph forward
to 0-4 mph in reverse .
- PARK for starting and when tractor is At Rest.
CAUTION
Do not place transmission lever into PARK position while
tractor is in motion. Premature shifting into PARK may result
in serious damage to the hydrostatic transmission.

PRE-OPERATIONAL CHECKS
EMERGENCY STARTING
The operator should become familiar with the following
pre-operational check list prior to starting or operating
the HUSKY.
1. Thoroughly clean area around crankcase oil dipstick,
and check for proper level of engine oil. See Engine
Manufacturer's Manual.
2. Thoroughly clean area around hydrostatic
transmission fill plug area, and check for proper level of
transmission fluid. See Lubrication Chart.
3. Check battery for proper water level.
4. Check gasoline tank for sufficient gas supply.
5. Check that air cleaner screen is free of debris. Check
and clean regularly. Replace if necessary.
6. Clean flywheel screen. Check and clean regularly.
7. Visually check for loose nuts and screws.
8. Check for 6-8 Ibs. tire inflation. TIRE INFLATION
SHOULD NOT BE LESS THAN 6 LBS.
In case of an electrical failure, proceed as follows:
1. Recharge or replace battery.
2. Jumper cables may be used. NOTE: If jumper cables are
used, cables must be connected, Positive (+) to Positive (+)
and Negative (-) to Negative (-).
3. After engine has started, allow it to warm up. Move choke
knob slowly forward, pull out throttle and lock at full speed.
4. Remove battery and have it fully charged as soon as
possible.
5. After the battery is fully charged, reinstall it in the tractor,
being careful to connect ground cable last.
6. Check generator belt for proper tension. Belt should
depress 1/4 inch between pulleys as shown in Figure 5.
Should adjustment be required, loosen generator mounting
screws and generator adjusting screw. Pivot generator
outward from engine until proper tension is obtained.
9. Do not allow ignition switch to remain in the on
position when engine is not running.
STARTING THE ENGINE
ELECTRIC STARTING
1. Be sure power take-off (P.T.O.) safety clutch is in the
OFF position, and the transmission lever is in PARK
position.
2. Pull out choke. Experience will indicate need for
more or less choking due to temperature variations,
grade of fuel, engine heat, etc.
3. Pull out throttle one-half way. More or less throttle
may be required due to grade of fuel and temperature
variations.
4. Turn ignition key against spring tension to actuate
starter. Release key when engine starts.
5. Allow engine to warm up. Move choke slowly
forward; pull out throttle and lock at full speed while
operating.
6. To stop the engine, bring engine back to idle, place
transmission lever in PARK and turn ignition switch off.
Remove the ignition key when the tractor is not in use,
or left unattended.
Figure 5
NOTE
Never pry out generator with a long heavy bar or tool as this
could result in premature bearing failure.
7. Tighten the generator mounting screws and generator
adjusting screw. Make sure all bolts are torqued securely.
