Manual
Recommended for
confined areas and on steep hills
The Twiga range of reach mowers have as standard a
slew ram to position the machine from transport to
work or any position midway for narrow lane cutting.
This ram also acts as the break back ram for machine
protection should an obstacle be encountered while
travelling forward.
The break back will operate if the machine is
overloaded i.e. a dense patch of vegetation, too high
a forward speed, and when working uphill. The
tractor must be halted and the flail head manoeuvred
around the obstacle before the break back is reset via
slew control lever / switch.
Auto reset
Recommended for
normal use
This is recommended for normal use either verge
mowing or hedge cutting. When auto reset is
selected the flail head rises as the arm slews back
past an obstacle, once past, the weight of the head
causes the arm to automatically slew forward and
down to the original position. Therefore, when verge
mowing, too much weight on rear roller will cause arm
to break back prematurely, as will too high a forward
speed and a dense crop.
Under certain conditions it may be beneficial to turn
off auto reset and operate break back manually,
especially in confined areas and up steep hills.
Warning
Never attempt to operate the machine when travelling backwards, the
break back will not function and any damage caused will not be considered
warranty.
The break back feature does not excuse the machine operator of their need to
be aware of obstacles and to avoid hazards. It is your responsibility to maintain a
long reliable working life.
