Troy-Bilt 1942/2246/2350/2454 Benutzerhandbuch

Shut the engine off and remove 

ignition key before removing the cutting blade(s) for 

sharpening or replacement. Protect your hands by 

using heavy gloves when grasping the blade

Periodically inspect the blade and/or 

spindle for cracks or damage, especially after  you’ve 

struck a foreign object. Do not operate the machine 

until  damaged components are replaced.

To remove the blades, proceed as follows.
1. 

Remove the deck from beneath the tractor, (refer to 

Cutting Deck Removal earlier in this section) then gently 

flip the deck over to expose its underside.

2. 

Place a block of wood between the deck housing baffle 

and the cutting blade to act as a stabilizer. See Figure 7-6.

3. 

Remove the hex flange nut that secures the blade to the 

spindle assembly. See Figure 7-6.

4. 

To properly sharpen the cutting blades, remove equal 

amounts of metal from both ends of the blades along the 

cutting edges, parallel to the trailing edge, at a 25°- to 30° 

angle. Always grind each cutting blade edge equally to 

maintain proper blade balance. See Figure 7-7.

If the cutting edge of the blade has 

previously been sharpened, or if any metal separation 

is present, replace the blades with new ones.

A poorly balanced blade will cause 

excessive vibration, may damage the tractor and/or 

result in personal injury.

5. 

Test the blade’s balance using a blade balancer. Grind 

metal from the heavy side until it balances evenly.
NOTE: When replacing the blade, be sure to install the 

blade with the side of the blade marked ‘‘Bottom’’ (or with 

a part number stamped in it) facing the ground when the 

mower is in the operating position.

Use a torque wrench to tighten the 

blade spindle hex flange nut to between 70 ft-lbs 

and 90 ft-lbs. 

The V-belts found on your tractor are 

specially designed to engage and disengage safely. 

A substitute (non-OEM) V-belt can be dangerous by 

not disengaging completely. For a proper working 

machine, use factory approved belts.

All belts on your tractor are subject to wear and should be 

replaced if any signs of wear are present . To change or replace 

the deck belt on your tractor, proceed as follows:
1. 

Remove the deck as instructed earlier in this section under 

Cutting Deck Removal.

2. 

Loosen, but do not remove the hardware on the right and  

left idler pulley.
NOTE: On some decks it may be necessary to remove the 

spindle covers to remove and/or install the new belt. To 

remove the spindle covers, remove the screws securing 

them to the deck.
