The EGGERS dynamometer PT 401 covers the complete spectrum of all performance classes for both tractors and harvesters.

Whether in the practical box trailer as the PT 401 K for mobile use, or stationary as the workshop version PT 401 W – you will get a lot of performance with this dyno. With a power of 900 kW (1224 HP) for the quick test and 510 kW (694 HP) for a full load curve, you can handle any engine.

Equipped with a torque measuring shaft in the drive train, the highest levels of accu - racy are achieved. With this dynamometer you are also prepared for the future in terms of precision and performance. With ever performance increasing agricultural machinery and the growing demands on performance test benches, an EGGERS dynamometer PT 401 is certainly the first choice for future-oriented companies.
