General
Gason Delta mowers are designed and built to with-
stand the toughest of conditions from everyday
contractor demands to the seasonal roadside slash-
ing requirments, when cared for and maintained as
suggested in this and the general operators manu-
als.
Operating Speed
It is recommended that the Gason Delta mowers
be used at speeds of up to 8 - 15km/h Travelling at
speeds in excess of this may affect cut quality and
finish.
The speed will be dictated by the application, ground
conditions, tractor HP and cutting height.
Gason recommend always commencing cutting
at low operating speeds then steadily increasing
speed. The operator should always be observant of
the machine’s cutting performance at all times to
ensure a neat, even finish.
Cutting Height
The Gason Delta Mower is designed to slash grasses
and general pasture and provide an even spread of
cut material. It is designed to cut at low heights. In
order to avoid premature wear or fatigue it is im
-
peritave the machine be set-up correctly to avoid
ground contact when cutting low.
Pull Angle
The Gason Delta Mower is designed to work through
a fore-aft angle of ±15°from the horizontal. Working
the machine over ruts and bumps greater than this
may cause premature failure of the tow eye , pull or
PTO’s and may also damage blades and rotor bars.

Machine Application & Capabili
ties
165°
Wing Angle
The Delta Mower can operate in ground up to 45°
above and 20° below horizontal as represented in
the below image by letters A & B.
Gason recommend that at all times the wheels re
-
main in contact with the ground when in operation.
Failure to do this may result in excess stress on cyl-
inders and may result in premature failure of the
machine.
Trouble Shooting
Why am I getting excessive skid wear?
In most cases excessive skid wear is a result of in-
correct machine set-up. Read the Tractor Connec-
tion section of the General Operators manual to aid
in finding the set-up error. As a guide, skid position
should always be approximately 12mm from the
ground level when operating.
Why does my machine not follow the ground con-
tour?
The Delta Wing Mower uses an hyraulic float sys
-
tem. In order for this to work the tractor control
lever for the wing lift circuit must be put into the
float position. Refer Tractor Operators manual for
more information on how to do this. Failure to do
this may result in premature wear of cylinder con-
nection points or in extreme cases cracking around
the hinges of the machine.
Why have my gearbox bolts come loose?
In most instances the bolts on the gearbox loosen
as a result of severe load being placed back into the
gearbox generally caused by continous scalping of
the ground.
Note: refer to torque specification page.
