Troy-Bilt 546 Manuel D’Utilisation

10

The grass catcher, located at the rear of the mower, is 
used to bag the grass clippings for disposal at another 
site. Once the bag is full, it has to be removed from the 
mower and emptied before any further mowing.

Instead of collecting grass clippings in a grass catcher, 
this mower has the option of recirculating the clippings 
back to the lawn. This is called mulching. Remove the 

grass catcher and the side-discharge chute from the 
mower, and operate with the mulching plug only for this 
purpose.

NOTE:  You must service the engine with oil and
gasoline before starting the mower for the first time.
Check oil and gasoline levels and fill up as necessary
for subsequent starts.

•

Check oil level and add oil if necessary. Follow 
relevant instructions in the engine manual for this. 

•

Service the engine with gasoline as instructed in 
the engine manual. 

•

Attach spark plug wire to spark plug. Make certain 
the metal cap on the end of the spark plug wire 
(inside the rubber boot) is fastened securely over 
the metal tip on the spark plug.

•

(On Model 549 only, Model 546 skip to next bullet 
point) Push primer three times. Wait about two 
seconds between each push. In cold weather 
around 55° F or below, prime five times. Do not 
prime to restart a warm engine after a short 
shutdown.

•

Standing behind the mower, depress the blade 
control handle and hold it against the upper handle.

•

Grasp starter handle and pull rope out slowly until 
engine reaches the start of compression cycle 

(rope will pull slightly harder at this point). Let the 
rope rewind slowly. 

•

Pull rope with a rapid, continuous, full arm stroke. 
Keeping a firm grip on the starter handle, let the 
rope rewind slowly.

NOTE: See your engine manual packed with your unit
for more detailed instructions.

•

Release blade control handle to stop the engine 
and the blade.

•

Disconnect spark plug wire and move away from 
spark plug to prevent accidental starting. 

•

You can use your mower as a mulching mower or a 
rear bagger. 

•

Be sure that the lawn is clear of stones, sticks, wire, 
or other objects which could damage lawn mower 
or engine. 

•

For best results, do not cut wet grass. New grass or 
thick grass may require a narrower cut.

Read, understand, and follow all 

instructions and warnings on the machine and 
in this manual before operating.

Use extreme care when 

handling gasoline. Gasoline is extremely 
flammable and the vapors are explosive. Never 
fuel the machine indoors or while the engine is 
hot or running. Extinguish cigarettes, cigars, 
pipes and other sources of ignition.

Be sure no one other than the 

operator is standing near the lawn mower while 
starting engine or operating mower. 

Never run engine indoors or in 

enclosed, poorly ventilated areas. Engine 
exhaust contains carbon monoxide, an 
odorless and deadly gas. 

Keep hands, feet, hair and 

loose clothing away from any moving parts on 
engine and lawn mower. 

If the mower strikes a foreign 

object, stop the engine. Remove spark plug 
wire from the spark plug and thoroughly inspect 
for any damage. Repair the damage promptly 
before restarting and operating the mower.
