Operation (1)
Warning:

To eliminate injuries, make sure that the deflector chute is installed and works properly. Never
use the mower deck unit without a chute or with the chute raised.

To eliminate injuries, never direct the discharge of the mowed grass on people in the vicinity
and ensure that no one is in the vicinity of the machine during operation.
Notice:

To eliminate injuries and damage to the device, tighten after the first hour of operation all
fasteners, including the fasteners of blades and spindles.
The operator is responsible for the safe operation of the tractor.
Before starting operation, the operator must be familiar with all tractor controls, their functions and how to
control them, and all safety features.
The tractor is designed for final cut mowing.
Only the operator may drive on the mower. Under no circumstances may anyone other than the operator be
present on the tractor.
The cutting height of the mower deck is adjusted by adjusting the position of the hitch pin at the rear of the
three-point hitch and allows the hitch pin to rest on the drawbar. For the correct setting, see the ''Adjusting
the Cutting Height'' chapter in this manual.
Lawn anti-scalp wheels on both sides of the mower deck are used for guidance while mowing.
When mowing, adjust the mower deck so that the anti-scalp wheel overlaps the edges of the previously
mowed lawn. This guarantees full coverage of the area to be mowed.
When mowing, the tractor engine must run at the recommended speed.
Do not mow at high travel speed. Operating the mower deck at the recommended engine speed will ensure
adequate blade speed for efficient mowing and grass removal from the mower deck.
For best results, it is recommended that during the first two passes around the area to be mowed, the
discharge chute is directed towards the center. After completing the first two passes, turn the direction, the
discharge chute should be directed outwards. This will ensure a better look of your lawn.
The sharpness of the blades affects the appearance of the cut surface. Blunt or damaged blades will cause
the appearance of the lawn to look ripped rather than cleanly mowed.
Do not mow the grass too short. Short grass supports weed growth and yellowing in dry weather.
In the heat and dry season, let the grass grow longer. Longer grass reduces heat accumulation, retains the
necessary moisture and protects the grass from heat damage.
Mow often. Do not allow the lawn to be tall. Mowing areas with tall grass may require pre-mowing the lawn to
the maximum cutting height. After mowing to the maximum cutting height, you can mow the area again with
the mower deck set to the requested cutting height.
