Active Suspension System
The first Active Suspension seat
was developed with John Deere & Co. in 2001. The
Active suspension concept was recognised as being
a major advance in seat technology which resulted
in it winning the gold award for Innovation at Agritechnica
This new innovation consists of
a hydraulically powered accuator/valve/contoller/sensor
system that acts upon the suspension linkage to negate
the effects of the vehicle inputs.
Senses and compensates
for vertical movements, and it can isolate up to 90% of the
vertical seat movements.
Speed sensitive to provide superior ride
performance regardless of the terrain, which reduces body
mass vibrations. This puts less strain on the operator, reducing
fatigue and increases productivity.
