Vehicle configurator

This vehicle is a rapid series model that is available at short notice.

“The hydraulic shifting system has to be one of the highlights of our LOGO 21. It’s really easy to move the rear pair of stakes by up to 1800 mm using the crane. That makes it much easier for us to load the final stack of timber.”

Julian Reith, Forstunternehmen Reith e.K.
