Remote Controlled - BuWizz 3.0 / 2.0 or LEGO® Power Functions
Prinoth Leitwolf R3
This snow groomer, based on the original Prinoth Leitwolf, is a release 3 redesign and succeeds the Prinoth Leitwolf NT model designed in 2007. Since then, the LEGO® Company launched a variety of new parts to justify an upgrade.
The model is powered by a BuWizz 3.0 unit, controlling a mix of LEGO® powered-up and power functions. A 100% power functions ONLY version is applicable as well, based on the LEGO® PF IR-receivers. A summary of the applied release 3 changes: The front blade is now able to tilt forwards or backwards - which was not the case in the previous version - and is still able to raise or lower; both functions can be remotely controlled. Blade rotation is manually, as well as opening or closing of both blade wings. The rear tiller remained almost the same. From an operational reality perspective, the model is now equipped with multiple mini-Linear Actuators (6x in the front blade, 1x in the rear tiller). The drum winch faced an increase drum size and a recolor to black. Added are LED headlights and rear light. Finally, the looks are significantly changed to have a new fresh appearance.
Functions still remaining are the track tension system, the pneumatic level adjustment and working V6 engine inside.
The drum winch can easily applied afterwards and can tilt to provide engine access.

BuWizz Profile
Front blade positions
Snow groomers do have occasionally a drum winch, used to anchor the snow groomer on - for instance - a concrete block when crawling very steep slopes (the 'black' ones).
The Prinoth Leitwolf equipped with a drum winch is able to anchor itself over 850 meter distance!
The drum winch can be added afterwards to the model, because the mounting points are already available.
