How to improve your Land leveling efficiency？

No need to install accessory tank

Clever design of the solenoid valve circuit, the whole system can complete the automatic operation control by using the original hydraulic output, without the need to install the auxiliary tank, reducing costs.

Automatic control blade

Obtain the average height of a plot or the height of a specific point and set it as a datum to start working without the need to manually manoeuvre the hydraulic lever.

No line-of-sight distance

The advantage of GNSS levelling is that it does not rely on the laser of laser levelling, only need satellite signal, it can guarantee high precision operation.

High accuracy for improved efficiency

The system is compatible with horizontal mode and achieves a levelling accuracy of ≤2.5 cm (1 inch). Operating with high accuracy in land levelling reduces the effects of droughts and floods, optimises soil moisture levels and ensures even irrigation. It also conserves water and fertiliser resources, retains soil nutrients and ultimately increases agricultural productivity.
