A NEW system which can change tractor tyre pressures from within the cab, was launched at LAMMA this week and will also be on show at the forthcoming CropTec event.

Tractair showed its central tyre inflation systems (CTIS) off at LAMMA and pointed out that tractor and trailer tyre pressures are critical to get the best from your machine both on and off road, whilst avoiding soil damage and wasted fuel.

In the field, low pressures spread the weight of the machine and maximise grip, while on the road higher pressures are needed for stability, fuel efficiency and minimum tyre wear. In both situations the best pressure also depends on the work being carried out and the

load on each axle.

A Tractair spokesman said: "Working with the correct pressures has many advantages – for one there's reduced wheel slip in the field, which can lower fuel consumption by up to 15%. There's also reduced soil compaction to maintain drainage and this could be beneficial in minati8ning crop yields.

"We also see reduced tyre wear and damage by up to 20%, plus there's increased grip and stability on the road and improved self cleaning of tyre tread in the field. This means that soil deposits on the roads near field gates are reduced considerably."

The system launched by Tractair is also compatible with dual wheels. Changing pressures from inside the cab can either be on a dedicated control panel, or built into the tractor's own display unit.

This can be done while at any speed, with the air supply coming from an on board engine driven compressor, or by a separate high performance hydraulic driven unit which can be mounted anywhere on the vehicle.

Trailer and implement tyre pressures can also be controlled from inside the tractor.
