Uphill at full power.

High-performance forwarding, flexible use and quick conversions are also possible in combination with Pfanzelt Professional series forwarding trailers. A thrust of 6.1 metric tons is available if the forwarding trailer features a powerful wheel hub drive.

More details on Pm Trac 8-wheel

The chassis

From the outside, the Pm Trac hardly looks any different. However, much has been further developed on the chassis, and new components are used. The chassis is built over a frame in which the individual units are installed. The biggest change to the chassis concerns the transaxle. The transmission and rear axle unit was previously purchased from ZF. With the new series, Pfanzelt produce the unit themselves – the variaDRIVE transmission as well as a new, planetary-driven rear axle from Pfanzelt are used. The Pm Trac Generation 38 is now based on an almost 100% Pfanzelt tractor chassis. This enables the complete adaptation of all components to heavy-duty use in forestry and as a multipurpose tractor. The days of using components from agricultural tractors are over. The Pm Trac plays in a new league.

variaDRIVE

The comfortable and powerful handling corresponds to that of familiar power-split transmissions. However, additional comfort is offered when changing the direction of travel. This operates more gently and quickly. In this way, it is comparable to that of a hydrostat. The new transmission is also efficient and performance-oriented thanks to the three travel ranges in forward drive and two travel ranges in reverse drive.

  • Top speed 40/50 km/h
  • Motor gear management
  • No switching of clutches in shunting mode up to approx. ±7 km/h
  • Reduction of the engine speed when the final speed is reached
  • Individual preselection of maximum speed for special applications (for example, forestry milling)

Implement and mounting compartments

In addition to the rear mounting compartment which is positioned with a favourable centre of gravity above the rear axle, the Pm Trac has a three-point implement compartment on the front and rear. Optional front loader consoles are available.

  2. Rear three-point linkage
  3. Front three-point linkage
  4. Front loader console

Pfanzelt System for Attachment (PSA)

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.

Forestry protection

The Pfanzelt forestry protection concept of the Pm Trac also includes complete protection for the chassis in addition to the dashboard, roof and engine hood.

Road travel

A roadworthy transmission technology and a standard road approval for 50 km/h allow the operator to approach or change locations quickly and without additional transport technology. The vehicle can also be driven on public roads in combination with a forwarding trailer or a trailer chopper.

The lighting system and fenders required for road travel can easily and quickly be converted for forestry operations. The four fenders, which are mounted as a pluggable system, are taken off the vehicle. The side indicators and front lights are concealed behind protective devices.

XXL cab

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.

The new machine software

The intelligent machine control system, which is operated via a touchscreen monitor on the seat, allows presettings to be stored for four operators. A Pfanzelt default user, which cannot be modified, is also stored.

An additional operating terminal for road travel is located next to the steering wheel. All important parameters are displayed there in the driver’s best possible view.

The new command centre on the rotating operator station

  • Driver management for four drivers incl. individual assignment of joysticks and control levers
  • Presets for hydraulic control units, crane functions, and auxiliary pumps
  • PTO management
  • Engine speed management
  • Adjustment of the driving characteristics

Excerpt from the extensive menu navigation

  • Adapted to the driver; he can individually preselect the assignment of all joystick functions and operating levers for hydraulic control units at the operator station, and save them in the driver management system.
  • The hydraulic management allows presetting of all crane functions (including flow regulation, adjustment of characteristics of individual hydraulic functions and ramps).
  • In addition to the preselection of speed and start-up characteristic, an automatic switch-on and switch-off can also be preset in the PTO management.

Service friendly

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.

Stowage space

Chainsaws, fuel canisters and other useful accessories can be stowed practically and tidily in a large tool box under the entrance into the driver’s cab.

Create an 8-wheel system thanks to forwarding trailers

In this combination the Pfanzelt Professional P17 forwarding trailer boasts a payload of 15 metric tons and a drive force of 6.1 metric tons. As a result the 8-wheel system generates a thrust of 16.1 metric tons. This means the vehicle can also cope with challenging terrain and it keeps damage to substrate to a minimum. The Pm Trac electronically and fully automatically controls the forwarding trailer’s drive speed. Operators can make any required adaptations. Consequently, it is possible to adjust the lead or lag.

The range of the steerable draw bar totals 68 degrees to thus make the combination agile and enable manoeuvring in confined spaces.

The electronic terminal features a large display to monitor the drive system and all important operating states. The terminal also enable a configuration of different adjustment options.

Using the cable winch with the forwarding trailer

If required, the remote-controlled, dual-drum cable winch that has been installed at the rear below the crane remains fully functional, even with attached forwarding trailer. Consequently, the unit provides an unrestricted attachment of tree trunks outside the crane’s reach using cables as well as felling with cable winch support.
