Dyno Tractor is a diagnostic system developed for agricultural vehicles provided with cardan shaft.
Supported by a management unit, it allows to measure a number of parameters like the engine power value. Dyno Tractor’s shaft brake is released with high quality material that warrants high twist resistance. A standard joint cardan shaft (optional) allows easy connection to the vehicle and makes it possible to quickly perform the following measurements: 

  • Maximum take-off power
  • Maximum engine power
  • Maximum take-off torque
  • Maximum engine torque
  • Cardan shaft rpm
  • Intake manifold pressure
  • Water / oil temperature
  • Exhaust gas temperature


Dyno Tractor is equipped with eddy current brake. Two models are available: the  single brake version -  allowing the measurement of up to 250 Kw engine power – and the double brake version - allowing the measurement of up to 500 kw engine power. Its modular structure allows you purchasing an upgrade to update the machine from the single brake version to the top version.

The available test for the measurement and diagnostic are:

  • Timed constant engine rpm test
  • Constant traction test
  • Manual braking test
  • Decelerative test
  • Real time data logger


A user-friendly software and no hardware allow to work with a notebook directly from the driver’s seat of the tractor. Measured values can be assessed thanks to both the digital displays and the graph. By moving the cursor on the chart, the related value is automatically displayed.

Con DYNO TRACTOR TRAILER raggiungi il trattore ovunque!

No matter where the tractor is… reach it with DYNO TRACTOR TRAILER and test it!

New born in the DIMSPORT dynamometers range, to support specific mobility needs in the Agricultural industry: a brand-new application has been developed to make any testing/diagnostic operation more practical and to allow time savings for Professionals of the engine calibrations and their clients.

Dyno Tractor Trailer DF2TR-TR is an evolution of the already existing DYNO TRACTOR platform, so far available with single brake (DF2TR - 250 kW version) and double brake (DF4TR – 500 kW version) frames. Like the previously released modules, this new application supports tests on Agricultural machines provided with PTO (Power Take-Off),but the distinctive aspect is the new wheeled frame to allow road transportations and so to reach the vehicles directly in the field.

Provided with single brake 250 kW mobile frame, Dyno Tractor Trailer introduces the portability as new business concept for Professionals aimed at offering the most efficient “on site” testing service.  No need to wait for Agricultural vehicles at your workshop (with all the problems that this transportation may involve…): just go and test it wherever this is needed.

A new feature added is represented by the possibility to test any kind of PTO. Dyno Tractor Trailer supports the rotation from both sides: it is now possible to test and support also front PTO (available on combined harvesters and some tractors),other than rear PTO.

The trailer on which the dynamometer is installed is equipped with identification number, certificate of conformity and all the necessary documents required to obtain a valid registration certificate.

Like other DYNO TRACTOR modules, this new application is provided with data acquisition probe kit as standard. Optional items are available: a cardan shaft, a kit of 3 universal adapters for the cardan shaft and a fuel consumption meter device.
