PTO dynamometer

The Sigma-60 PTO dynamometer is currently the most modern dynamometer for measuring power and torque in agricultural tractors from all over Poland.


It allows current reading of power, speed and torque.
this is extremely important when diagnosing tractors and increasing power
Sigma-60 can finish measuring successfully in a couple of minutes.


Simple yet sophisticated design means that there is no need to warm up the dynamometer and to perform calibration before measurement. The testing facility can carry out tests on a full range of agricultural machinery from tractors to combine harvesters.

  • high sampling rate - the tester collects measuring points every 100 ms - very high accuracy of measurements,
  • continuous, not discrete, measurement- this allows you to examine points that other dynamometers overlook
  • measuring length - the dynamometer can virtually work without interruption under maximum load,
  • full automation of the device guarantees trouble-free measurement - quickly and accurately,
  • limit parameters are 700 HP and 5000 NM - only Sigma-60 can actually measure it.

 The Sigma series is used around the world to confirm the power and

performance of a given engine. They are used for routine inspection

before deliveryof new tractors (including John Deere and JCB plants).

Repair services use it for diagnostics and troubleshooting in used tractors.
