Mobile and cost effective scale for tractor three-point hydraulic systems

This specially designed, mobile and inexpensive scale turns every tractor three-point linkage into a 6000 kg scale. The AGRETO three-point scale is simply mounted between tractor three-point linkage and implement.

Easy to attach to various implements

Implements seldom conform to category II dimensions, but the AGRETO three-point scale can be used everywhere nonetheless, thanks to the infinite adjustability of the length of the lower link (85-90 cm) and the height between lower link and top link (48-68 cm).

Certainty with regards to input and output

Continuous information on quantities entering and leaving the vehicle enables the correction of erroneous settings.

Cost savings on resources

You only distribute the needed amounts and thus prevent overdosage.

Highest possible transport and operation security

Even when in an exceptional situation a load cell breaks, the construction of the AGRETO three-point scale prevents the loss of your implement and the enormous damages involved.

How does the AGRETO drive-over-scale function?

The AGRETO drive-over-scale weighs vehicles dynamically while in motion. Weighings are automatically registered and stored on your PC.

Do I have to stand still on the platform with each axle?

Generally speaking, no. The AGRETO drive-over-scale is designed for dynamic weigh-in-motion. Axles are automatically weighed one after the other. Only when you weigh liquid containers or barrels that aren’t completely full, do you need to weigh statically, ie stand still on the platform with each axle. The software contains a separate mode for that.

How fast can I cross the scale?

You have to drive at walking speed. The best results are obtained when driving 2 to 4 km/h with agricultural vehicles, and 4 to 6 km/h with trucks. The AGRETO drive-over-scale monitors your driving speed and issues a warning when a weighing isn’t optimal due to too much speed.

Do I have to specify the amount of axles up front?

No, not at all. The AGRETO drive-over-scale software automatically registers the amount of axles.
