Troy-Bilt ZT50 Manuel D’Utilisation

The front of the deck should be approximately 

1. 

1⁄4” lower 

than the rear of the deck. Adjust if necessary as follows:
With the deck raised off of the ground, rotate the outer 

2. 

blades so that they are parallel to the frame of the tractor.
If the side to side leveling was done correctly, measuring 

3. 

just the right blade should be acceptable to attain the 

correct back to front pitch of the deck. 
Measure the distance from the front tip of the blade to the 

4. 

ground and the distance from the rear tip to the ground. 

The front distance should be approximately 1⁄4” less than 

the rear. If it is not, proceed to the next step.
From the front of the tractor, loosen the outer hex nuts on 

5. 

the deck front hanger rod and turn them away from the 

inner nuts. Refer to Fig. 6-5.

If the front of the deck was too low, turn the inner hex nuts 

6. 

clockwise against the hanger bracket to shorten the front 

hanger rod and raise the front of the deck. Refer to Fig. 6-5.
If the front of the deck was too high, turn the hex nuts 

7. 

counterclockwise to lengthen the front hanger rod and 

lower the front of the deck.
NOTE: The deck front hanger rod should be at the front of 

the slots of the front deck bracket. If one side of the rod is 

not at the front of its slot, turn the inner hex nut on that 

side until rod just touches the front of the slot. Then re-

measure and re-adjust the front hanger rod as necessary.
When the correct pitch of the deck is acquired, secure the 

8. 

inner hex nuts with a wrench and tighten the outer hex 

nuts against the inner hex nuts to lock them in the adjusted 

position.

Keep hands and feet away from the 

discharge opening of the cutting deck.

NOTE: The deck gauge wheels are an anti-scalp feature of the 

deck and are not designed to support the weight of the cutting 

deck.
The mower deck cutting height can be set in any of six height 

settings using the tractor’s deck lift handle. The deck heights 

range from 1-1⁄2” to 4”. The deck gauge wheel position should be 

approximately 1⁄4 to 1⁄2” above the ground when the deck is set in 

the desired height setting.
Using the lift handle, set the deck in the desired height setting, 

then check the gauge wheel distance from the ground below. If 

necessary adjust as follows:

Visually check the distance between the front gauge 

1. 

wheels and the ground. If the gauge wheels are near or 

touching the ground, they should be raised. If more than 

1⁄2” above the ground, they should be lowered.
Remove the lock nut securing one of the front gauge wheel 

2. 

shoulder screws to the deck. Remove the gauge wheel and 

shoulder screw. Refer to Fig. 6-6. 

Insert the shoulder screw into the one of four index holes 

3. 

in the front gauge wheel bracket that will give the gauge 

wheel a 1⁄4” to 1⁄2” clearance with the ground. 
Note the index hole of the just adjusted wheel, and adjust 

4. 

the other gauge wheels into the respective index holes of 

the other gauge wheel brackets on the deck.
