Electronically controlled front hitch with implement relief marks a milestone in agricultural machinery
Working with the front hitch has never been easier. The electronic front hitch (EFH) sets new standardsin its class and makes the Multi a true master of versatility. The “Steyr — Improving the efficiency of tractors in Alpine environments with the electronic front hitch” project has been heralded as a milestone in agricultural machinery.The EFH automatically raises implements up to the preset height only, while the ground pressure is kept constant in the lowered position. This means better control of front-mounted implements, such as mowers, front packers and many more.

Benefits of the EFH over the standard front hitch


Standard front hitch
The entire weight of the front mower is exerted on its sliding plates.The high pressure exerted on the ground reduces the quality of the grass and silage and does not conserve the soil effectively.
Electronic front hitch (EFH)
The load sensor of the EFH control valve detects the ground pressure exerted by the front-mounted implement and allows the operator to make adjustments from the cab. The lower ground pressure exerted by the implement improves the quality of the grass and helps to conserve the soil.The higher load on the front axle also makes it easier to steer the tractor on level terrain, as well as when driving across slopes.

Behaviour of the EFH on terrain


Standard front hitch

When working with a standard front hitch, the height of the front-mounted implement is controlled in relation to the position of the front wheels.

However, the front wheels reach uneven terrain after the implement. The ground pressure exerted by the attachment therefore initially increases, while the pressure of the wheels is reduced. This damages the turf and may cause the crop to become contaminated by earth.

with implement relief

The load sensor of the EFH automatically detects changes in the ground pressure exerted by the implements on uneven ground, and raises or lowers the implements accordingly to keep the pressure constant. This results in higher grass quality, better soil conservation, enhanced steering control and increased comfort for the operator.
