Avant 528 ArborPro Mini Loader Demostration for an Arborist

The Avant 528 ArborPro mini loader with the Optidrive™ drive circuit that gives more power for driving and hydraulic attachments.

All Avant articulated mini loaders are equipped with a hydrostatic drive system. There is a hydraulic drive motor on each wheel. The drive circuit is equipped with valves with which traction can be controlled in different situations. In order to avoid tyre marks on soft and sensitive surfaces when turning, the system allows the wheels on the left and right sides of the articulated loader to roll at different speeds. This also reduces tyre wear on hard surfaces.

The valves in the drive system work like a hydraulic 4×4 diff lock and equalize the oil flow between the left and right side hydraulic motors, improving traction on slippery and uneven surfaces.
