Operation (2)
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.
At certain times of the year and under certain conditions, the tractor may leave stripes of uncut grass.
The main cause is tall grass and weeds. Under these conditions, it may be necessary to mow the lawn once
more to achieve an even cut.
Cutting a large proportion of the length of grass blades at once can damage and weaken the plant's growth
system.
A good guide is the one-third rule: do not cut more than one-third of the height of the grass and never more
than 2.5 cm.
Mow the grass if it is between 7.5 and 10 cm tall.
The time of day and the condition of the grass will affect the result of mowing.
Mow at a time when the grass is cold and dry. The most ideal mowing conditions are in the late afternoon or
early evening.
