How a PTO generator works
The generator is driven by the tractor’s power take-off shaft, so no separate engine is needed. The recommended PTO speed is 430–450 rpm, which corresponds to a tractor engine speed of about 1500 rpm.
Frequency and voltage depend on the rotation speed. For this reason, large indicator lights show the driver whether the speed is in the right range. This is the so-called traffic-light function.
In addition, the frequency and voltage display lets you follow use and load closely. The operating hours counter makes it easier to track servicing.
EZG 25/2 II/TN-S in field use and as standby power
In field use, the generator operates as an IT network with active insulation monitoring. The monitoring detects insulation faults and improves electrical safety in mobile installations.
When feeding a building’s electrical installation, the TN network is used. Protection is then provided by an all-pole miniature circuit breaker.
As a result, the same unit works both as a mobile power source and as standby power.
Sizing and choosing the tractor
The recommended tractor output is about 50 hp, and the rated current is 31.7 A.
The feed-in socket (5-pin CEE, 1 h) is designed for the generator’s maximum output.
It is the smallest model in the series and suits smaller tractors. For a tractor of about 80 hp, the EZG 40/4 II/TN-S delivers 40 kVA.
Mounting, transport and accessories
The generator attaches to the tractor’s category 2 three-point linkage. The sturdy steel frame has forklift pockets for moving it.
The weight is about 220 kg. The dimensions are 1130 x 740 x 942 mm (L x W x H).
Accessories available: wheel kit E161036 and adapter for category 3 E162048. The feed-in socket CEE 400 V/32 A 1 h E135846 is also available.
EZG 25/2 II/TN-S in farm electrification
A PTO generator suits farms, livestock farms, machine halls, worksites and support for service vehicles. You can find all models in our generator range.
If no tractor is available, the same range also includes diesel generators with their own engine.
Safety
The automatic safety shutdown of the EZG 25/2 II/TN-S protects the electrical system from overload. The generator meets the safety standards of the Agricultural Employer’s Liability Insurance Association (DGUV).
Keep the PTO shaft guards in place and stay clear of the rotating shaft. Moreover, place the tractor outdoors so exhaust gases cannot enter buildings.
Connection to a building’s installation is always made by a qualified electrician. The requirements for electrical work are explained on the Tukes website.
