Troy-Bilt 77T Manuel D’Utilisation

Engaging the PTO (Blade Engage) transfers power to 
the cutting deck or other (separately available) attach-
ments. To engage the blades, proceed as follows:
1.  Move the throttle control lever to the FAST (rabbit) 

position.

2.  Grasp the PTO (Blade Engage) lever and pivot it all 

the way forward into the engaged (ON) position.

3.  Keep the throttle lever in the FAST (rabbit) position 

for the most efficient use of the cutting deck or other 
(separately available) attachments

IMPORTANT: The PTO (Blade Engage) lever must be in 
the disengaged (OFF) position when starting the engine, 
when traveling in reverse, and if the operator leaves the 
seat.

  Refer to Safety Interlock Switches on page 12.

To raise the cutting deck, move the deck lift lever to 
the left, then place it in the notch best suited for your 
application. Refer to Setting The Cutting Height earlier in 
this section.

The following information will be helpful when using the 
cutting deck with your tractor:

•  Do not mow at high ground speed, especially if a 

mulch kit or grass collector is installed.

•  For best results it is recommended that the first two 

laps be cut with the discharge thrown towards the 
center. After the first two laps, reverse the direction 
to throw the discharge to the outside for the balance 
of cutting. This will give a better appearance to the 
lawn.

•  Do not cut the grass too short. Short grass invites 

weed growth and yellows quickly in dry weather.

 

• 

GO UP AND DOWN SLOPES, NOT ACROSS. 

 

• 

AVOID SUDDEN TURNS.

 

• 

DO NOT OPERATE THE UNIT WHERE IT COULD SLIP  

 

OR TIP.

 

• 

IF MACHINE STOPS GOING UPHILL, STOP BLADE(S)  

 

AND BACK DOWNHILL SLOWLY.

 

• 

DO NOT MOW WHEN CHILDREN OR OTHERS ARE  

 

AROUND.

 

• 

NEVER CARRY CHILDREN, EVEN WITH BLADES OFF.

 

• 

LOOK DOWN AND BEHIND BEFORE AND WHILE  

 

BACKING.

 

• 

KEEP SAFETY DEVICES (GUARDS, SHIELDS, AND  

 

SWITCHES) IN PLACE AND WORKING.

 

• 

REMOVE OBJECTS THAT COULD BE THROWN BY 

THE    

BLADE(S).

 

• 

KNOW LOCATION AND FUNCTION OF ALL CON-

TROLS.

 

• 

BE SURE BLADE(S) AND ENGINE ARE STOPPED  

 

BEFORE PLACING HANDS OR FEET NEAR 

BLADE(S).

 

• 

BEFORE LEAVING OPERATOR’S POSITION, DISEN-

GAGE BLADE(S), PLACE THE SHIFT LEVER IN NEUTRAL, 
ENGAGE BRAKE LOCK, SHUT ENGINE OFF AND REMOVE 
KEY.

•  Mowing should always be done with the engine at full 

throttle. 

•  Under heavier conditions it may be necessary to go 

back over the cut area a second time to get a clean 
cut. 

•  Do NOT attempt to mow heavy brush and weeds and 

extremely tall grass. Your tractor is designed to mow 
lawns, NOT clear brush.

•  Keep the blades sharp and replace the blades when 

worn. Refer to 

Cutting Blades on page 21 of this 

manual for proper blade sharpening instructions.
