The Pfanzelt Pm Trac III tractor system, thanks to its unique vehicle design. is optimised for combined service in agriculture and forestry as well as in landscape management. With the new generation, a completely new vehicle chassis has now been developed with key components, however, that are based on tried and tested series production parts. The core of the Pm Trac machine are the central attachment bay over the centre of the rear axle and the rapid and flexible adaptation to various working conditions.

For handling long and short timber, the winch and the forestry crane are area mounted directly above the rear axle. Depending on the application, a forwarding crane or a loading crane can mounted while maintaining a favourable centre of gravity.
A high-pillar loading crane lends itself to operation in combination a forwarding trailer. The various crane types and the forestry cable winches can be dismantled<br/> quickly and easily via the Pfanzelt system mounting.
With the tail attachment bay with rear power lift other working implements such as boom-mounted mowing machines can be operated in combination with an additional green shoulder mower or flail mower. The Pfanzelt system mounting serves in the Pm Trac as the carrying frame. The extreme forces generated during the operation of heavy forwarding cranes or mowing booms are absorbed via the bearing frame and dissipated in a controlled fashion.
The Pm Trac deals capably with other forestry tasks beside standard forwarding. In addition to being used with a forest mulcher for surface cultivation, the Pm Trac can also fully exploit its strengths in combination with a Pfanzelt fuel wood felling gripper. When used with a felling unit or a mulching head on the forest crane, which requires greater hydraulic power, an auxiliary hydraulic system can be installed at the rear instead of the winch.
Operation with a shredder is also an option with the Pm Trac. Besides shredders with their own motors, the Pm Trac can also be combined with shredders driven by the tractor’s PTO. The rear PTO of the Pm Trac is always accessible even when a crane and cable winch are mounted.
When the forestry implements have been detached, the tractor can be used for agricultural purposes without any additional conversion work, as no modifications have to be made to the rear power lift or other components that are relevant for forestry operations.
In addition to the rear and front attachment area, the design of the system tractor also includes front loader mounting brackets. For local authority applications, a special coupling plate can be installed instead of the front hydraulics.
The Pfanzelt Forsttrac 2380 is a special version of the Pm Trac tractor system, optimised for the heaviest duty applications with cable winch and logging grab in the forest. A new vehicle configuration with front winch ensures optimum weight distribution and a high degree of soil protection. The sliding tube front axle with hydraulic suspension and automatic locking offers a new dimension in stability for crane operation.
The Pm Trac II has been mounted on a vehicle chassis from a leading tractor manufacturer. The frame was, however, originally designed for agricultural use and as a result had to be redesigned for use in forestry applications. With the new production series of the Pm Trac III, a completely new vehicle chassis has now been developed. The basis is a vehicle frame that has been designed from scratch for forestry use. The new front axle, in the form of a sliding tube axle with hydraulic suspension and automatic immobilisation, also constitutes an integral part of the new chassis. As soon as the Pm Trac comes to a halt, the hydraulic suspension is automatically locked. The vehicle now achieves a degree of stability that was previously only attainable by special forestry tractors.
The smooth-running and high-torque 6-cylinder DEUTZ engine of the Pm Trac models 2380 4f and 2385 4f with power ratings of 133 kW or 174 kW ensures maximum performance and minimum fuel and total operating costs.
The relocation of the cab to the centre of the vehicle means that additional implements can be mounted in the tail attachment bay by means of the Pfanzelt System for Attachment (PSA); as a result the attachments are directly over the rear axle.
Via a special quick conversion system, attachments can be changed without requiring tools in a very short time. For example, it now takes less than 20 minutes to attach or remove a crane or cable winch.
The operator can rapidly reach working locations or change between them with a permitted road speed of 50 km/h and a transmission suited for road use, and all without requiring an expensive transporter. Even in combination with a forwarding trailer or a trailer-chipper, the vehicle can still be driven on public roads.
The lighting systems and mudguards required for road use can be easily and rapidly removed for forestry operations. The four mudguards that are mounted with a snap-on system are in this case detached from the vehicle. The indicator lights and headlights are concealed behind protective panels.
The tractor cab developed by Pfanzelt with pneumatic suspension enable smooth and vibration-free operation.
The view over the working environment is further extended by 7 m² of window area. The driver has an even better view of his working zone, this means less stress and increasing safety. The driver has a relaxed and ergonomic sitting and working position on the operator stand that can now can be turned through 350° by electric motor. The intelligent machine controller which is operated via a touch screen from the seat – also saves the individual preferred settings for different drivers.
The Pfanzelt XXL cab has been especially created with the demands of our customers in mind – low vibrations when working in standing timber yet with maximum comfort when driving at 50 km/h on public roads.
All operating and monitoring functions are mounted on the seat and therefore always in the operator’s field of vision.
An additional control panel for on-road driving is provided next to the steering wheel. All key parameters are conveniently displayed in driver’s field of vision.
Unique in the forestry industry and essential for municipal use is the possibility to install a passenger seat in the driver’s cab as an option.
For forestry work, the steering column is simply and rapidly folded to one side.
Pfanzelt’s carefully designed service concept begins with easy access to the radiator and engine compartment for cleaning. The vehicle cab can be tipped up for easy access to the remaining machinery compartment. The loading crane and cable winch can be removed in a matter of minutes, exposing the remainder of the chassis.
The floor pan of the tractor can be additionally opened via a cable winch. This means that one person can safely work on his own.
