Power measurement and engine testing of agricultural machines
TractorTest performs power measurement of your tractor with one of our PTO dynamometers, where the entire power and torque curve is described.
At the same time during testing, extended logging is carried out by several computers on the tractor, which works either external physical sensors and/or CAN-Bus tracing. This gives an indication of the mechanical condition of the engine and the overall efficiency of the entire tractor.
The logging system describes, among other things, the fuel consumption and the tractor's general efficiency.
If the gearbox or hydraulic system is misadjusted, this will affect the test. In addition to this, the test can also reveal any future faults on the vehicle, without necessarily having any fault codes.
The logging system is made (written code) by TractorTest.eu and is therefore one of the only in the world that offers this within agricultural and industrial engines of brands such as Deutz, Fendt, Massey Ferguson, JCB, John Deere, Case, New Holland, Claas and Valtra.
TractorTest has tested hundreds of agricultural and industrial engines over many years, and has a huge database of logging values from all different manufacturers. In this way, it is always possible to compare whether there is an opportunity for optimization or whether repairs need to be made - before a total breakdown!

Power is defined as "work over time", i.e. "joule/second", whereby work is defined as "force*distance traveled", i.e. "Newton*Meter".
Power is controlled by torque at a given rpm. The relationship between power and torque can be described by the fact that 1 Watt is equal to 1 Nm/second and that 1 horsepower is equal to 746 watts.
It is only the power that controls how much work can be done per unit of time.
The effect is read via the line below on measurements made at tractorTest.eu, in addition to the relevant rpm.
Torque is defined as "Rotational Force". This is defined as "force*length", i.e. "Newton*meter".
If the torque is increased at 1600 rpm, then the power, at 1600 rpm, will increase accordingly as the torque controls the power in conjunction with the rpm.
The relationship between power, torque and rotational speed is described as: Power=Torque*Angular velocity. Angular velocity is defined as: ω=2·π·Rpm/60. Hereby, power and torque can always be converted. Torque is read via the line below next to the relevant rpm.
When measuring power, an environmental correction is usually corrected to the measurement. Tractortest' dynamometers support, among other, the standards DIN 70020, SAE J1349 and ISO 1585. The power correction means that a power measurement made on a cold winter's day will approximate a measurement made on a warm summer's day. Older engines actually perform differently for the two scenarios. This is what is corrected for.
The J1349 standard prescribes, for example, that the power measurement be adapted to an air humidity of 0%, an air temperature of 25 degrees C and an air pressure of 101.3 kPa.
About
Tractortest.eu was founded in 2014. Before that we had 10 years of experience within agricultural machinery. In 2008, focus changed to electrical control systems.
Over the years, intensive work has been done to build up a network within the electronic part of the machinery industry.
Later, I took a mechanical engineering degree specialized in software design, and continued this with a specialization in CAN systems and software design of controller systems, especially the SAE J1939 protocol which is used in e.g. Agricultural and construction machinery.
Tractortest has partners throughout Europe, enabling customized solutions, as well as the latest information on upcoming technologies.
20 years of experience with agricultural machinery.
10 years of programming and software design experience in agricultural machinery (J1939, J2534, ISO15765)
Large network with many business partners ensures you the best and most tested solutions
