By pressing the MODE button the
transmission mode can be changed between
Automatic, Manual and Creep.
• Automatic - When the hydraulic
transmission pedal or the mower
circuits are activated the engine speed
will increase to the rpm level selected
by the operator. When the foot pedal

seconds or the mowers are disengaged
the engine rpm will return to idle. Useful
to save fuel and decrease the noise
emissions.
• Manual - The engine speed is
determined by the throttle position
regardless of pedal position or whether
the mower circuit is engaged. Useful if a
constant engine speed is needed.
• Creep - The maximum speed of the
transmission is limited and can not be
exceeded past a predetermined level
even with the engine speed set at
maximum rpm. Useful when you move
the machine in a workshop or loading
for transportation.
