USING THE PTO  
To Engage PTO:  
TIPS FOR OPERATION  
1. Start the engine.  
Use slow gears when operating the tractor on rough  
ground, slopes, small areas, near buildings or other  
obstacles.  
2. After the engine is warm, move the throttle lever  
just above the SLOWposition.  
3. Move the gear shift lever to the NEUTRAL”  
Use a slow gear and a fast engine speed when  
operating a snowblower, rotary cultivator, or a mower in  
heavy grass.  
position. Depress an operator presence handle.  
4. Pull the PTO control back to the ONposition  
with one continuous, fast pull.  
Walk behind, never between the handlebars.  
5. Move the throttle lever to the FASTposition.  
6. Move the gear shift lever to the HIGHor LOW”  
position.  
NOTE: The gear shift lever must be in either the HIGH”  
or LOWposition to properly power the attachment.  
7. Operate the direction control lever for desired  
travel.  
To Disengage PTO:  
1. Stop the tractor with the direction control lever.  
2. Move the throttle lever to the SLOWposition.  
3. Move the gear shift to the NEUTRALposition.  
4. Push the PTO control in (forward) to the OFF”  
position.  
Using the Steering Brakes (optional)  
The steering brakes are used when the tractor is being  
driven forward.  
To make a right turn, push the brake handlebar to the  
left.  
To make a left turn, pull the brake handlebar to the  
right.  
CAUTION: Use only the tractor  
handlebars to steer when driving in  
reverse.  
To Travel to Another Work Area  
1. Disengage PTO.

MAINTENANCE  
CHECK FASTENERS  
Check all fasteners after 25 hours of operation to make  
sure that they are tight. Replace any fastener that is  
missing.  
MAINTENANCE SCHEDULE  
25 100 200  
CHECK CLUTCHES  
After 25 hours of operation, check the adjustment of  
the forward-reverse and gear clutches.  
The reverse clutch is adjusted correctly when the  
direction control lever stops 15 degrees past vertical to  
the rear. The lever should return to neutral position  
from reverse.  
Check Engine Oil  
Check Air Cleaner

The forward clutch is adjusted correctly when the  
direction control lever is in the full forward position and  
the large spring has a coil clearance of .010(.254mm).  
Check Engine Cooling

CHECK ENGINE OIL  
LUBRICATE TRANSMISSION  
Check the engine oil daily, or before each use. Never  
operate the engine when the oil level is below the low  
mark on the dipstick. See the engine manual for oil  
change schedule and detailed instructions.  
After every 100 hours of operation, check the level of  
the lubricant in the transmission. Never operate the  
tractor when the transmission oil level is below the  
LOWmark on the dipstick.  
CHECK AIR CLEANER  
Check the air cleaner daily. See the engine manual for  
detailed instructions.

Internal Contact: Drink large quantities of water.  
Follow with Milk of Magnesia, beaten egg or  
vegetable oil. Get medical attention immediately!  
7. Clean the area around the ller plug.  
8. Remove the ller plug.  
IMPORTANT: In case of internal contact, DO NOT

The tractor is equipped with a low maintenance battery.  
Check the uid level every 200 hours or at the end of  
the year. Keep the battery clean. If acid is on the  
outside of the battery or the electrical connections are  
corroded, clean the outside of the battery with water  
and baking soda solution. (Figure 7)  
10. Install the ller plug and the dipstick.  
SERVICE BATTERY  
When charging the battery remove it from the unit rst.  
When the battery cables are disconnected, remove the  
negative (-) (ground) cable rst. When replacing the  
battery cable connect the positive (+) cable rst. Any  
time the battery cables are disconnected, clean the  
cable clamps and the battery post or connection.  
WARNING: ELECTRIC SHOCK may  
result in injury and/or damage to unit.  
DO NOT allow objects to come into  
contact with both terminals at the same  
time.  
On tractors not equipped with a maintenance-free  
battery, remove the battery and place on a bench or  
other place which is well ventilated and acid spill will  
not create damage. Fill the battery to the bottom of the  
ll tubes with 1.265 specic gravity electrolyte. Twenty  
minutes after lling with electrolyte, charge the battery  
at 6 to 8 amps for 20 minutes. Follow charger  
REVERSE CONNECTIONS may result in  
sparks which can cause death or serious  
injury. ALWAYS connect positive (+) lead  
of charger to positive (+) terminal, and  
negative (-) to negative (-) terminal.  
ALWAYS connect positive (+) cable  
FIRST, and negative (-) cable SECOND.

STORAGE  
Check each item in "Before Storage" in the  
Maintenance Schedule. See Engine Manual for  
detailed instructions on preparing the engine for  
storage.  
NOTE: Do not use harsh or abrasive cleaners on any  
painted surface. Do not allow gasoline or oil to remain  
on any surface.  
3. Refer to the engine manual and prepare the  
engine for storage.  
When The Tractor Will Not Be Operated For  
Two Months Or More:  
4. Charge the battery initially and then every three  
weeks.  
1. Do the daily and 25-hour maintenance, but do not  
add gasoline.  
To Put The Tractor Into Service:  
2. Clean the tractor. Paint or oil bare metal surfaces  
to prevent rust.  
1. Refer to the engine service manual and prepare  
the engine for service.  
IMPORTANT: NEVER spray unit with water or store  
unit outdoors. Water can seep into sealed bearings,  
which are sealed against dirt and debris only, causing  
reduced component life.  
2. Charge the battery.  
3. Put fresh, clean gasoline in the fuel tank.
