Troy-Bilt 77T Manuel D’Utilisation

A mulch kit is sold separately and incorporates special 
blades that incorporate a process of recirculating grass 
clippings repeatedly beneath the cutting deck. The ultra-
fine clippings are then forced back into the lawn where 
they act as a natural fertilizer.
Observe the following points for the best results when 
mulching:
•  Never attempt to mulch if the lawn is damp. Wet grass 

tends to stick to the underside of the cutting deck 
preventing proper mulching of the clippings.

•  Do NOT attempt to mulch more than 1/3 the total 

height of the grass or approximately 1-1/2 inches. 
Doing so will cause the clippings to clump up beneath 
the deck and not be mulched effectively.

•  Maintain a slow ground speed to allow the grass 

clippings more time to effectively be mulched.

•  Always position the throttle control lever in the FAST 

(rabbit) position and allow it to remain there while 
mowing. Failing to keep the engine at full throttle 
places strain on the tractor’s engine and does not 
allow the blades to properly mulch grass.

NOTE: It is not necessary to remove the discharge chute 
to operate the mower with the mulch kit installed.
To operate the cutting deck without mulching, simply 
remove the mulch plug by unthreading the plastic wing 
nut which fastens it to the cutting deck. This will allow the 
clippings to discharge out the side. See Figure 9.

•  On some models, the lamps are ON whenever the 

tractor’s engine is running. On other models, the 
lamps are ON whenever the ignition key is moved out 
of the STOP position.

•  On all models, the lamps turn OFF when the ignition 

key is moved to the STOP position.

NOTE:  It is not neces-
sary to remove the 
discharge chute to 
operate the mower with 
the mulch kit installed.
