Troy-Bilt TB2450 Manuel D’Utilisation

Shut the engine off, remove the 

ignition key and engage the parking brake before 

making adjustments. Protect your hands by using 

heavy gloves when handling the blades.

NOTE: Check the tractor’s tire pressure before performing 

any deck leveling adjustments. Refer to Tires on page 25 for 

information regarding tire pressure.

The front of the cutting deck is supported by a stabilizer bar that 

can be adjusted to level the deck from front to rear. The front of 

the deck should be between 1⁄4” and 3⁄8” lower than the rear of the 

deck. Adjust if necessary as follows:

Park the tractor parked on a firm, level surface and place 

1. 

the deck lift lever in the middle position.
Rotate the blade nearest the discharge chute so that it is 

2. 

parallel with the tractor.
Measure the distance from the front of the blade tip to the 

3. 

ground and the rear of the blade tip to the ground. The 

first measurement taken should be between 1⁄4” and 3⁄8” less 

than the second measurement.

Determine the approximate distance necessary for proper 

adjustment and proceed, if necessary.

Loosen (thread outward) the hex lock nut on the end of the 

1. 

deck hanger rod. See Fig. 6-4.

To 

2. 

raise the front of the deck, tighten (thread inward) the 

inner hex nut against the front hanger bracket.
To 

3. 

lower the front of the deck, loosen (thread outward) the 

hex nut, away from the front hanger bracket.  

See Fig. 6-4.
Retighten the lock nut against the hex nut when proper 

4. 

adjustment is achieved.

If the cutting deck appears to be mowing unevenly, a side to side 

adjustment can be performed. Adjust if necessary as follows:

With the tractor parked on a firm, level surface, place the 

1. 

deck lift lever in the middle position and rotate both blades 

so that they are perpendicular with the tractor.
Measure the distance from the outside of the left blade 

2. 

tip to the ground and the distance from the outside of the 

right blade tip to the ground. Both measurements taken 

should be equal. If they’re not, proceed to the next step.
Loosen, but do NOT remove, the hex bolt on the left deck 

3. 

hanger bracket. See Fig. 6-5.

Using a wrench, raise or lower the left side of the deck by 

4. 

turning the adjustment gear. See Fig. 6-5.

The deck is properly leveled when both blade tip measurements 

taken earlier are equal. Retighten the hex bolt on the left deck 

hanger bracket when proper adjustment is achieved.

If the tractor does not come to a complete stop when the brake 

pedal is completely depressed, or if the tractor’s rear wheels can 

roll with the parking brake applied (and the hydrostatic relief 

valve open), the brake is in need of adjustment. See your Troy-bilt 

dealer to have the brake properly adjusted.

Refer to the Set-Up and Assembly section of this manual for seat 

adjustment instructions.

Warning! Before operating the tractor, make sure the 

seat is engaged in the seat-stop. Engage the parking 

brake. Stand behind the machine and pull back on 

seat until it clicks into place.
