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 40/4 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 80 hp, and the rated current is 57.7 A.

The feed-in socket (5-pin CEE, 1 h) is designed for the generator’s maximum output.

The smaller EZG 25/2 II/TN-S suits tractors of about 50 hp. The larger EZG 60/4 II/TN-S suits tractors of about 120 hp.

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 266 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/63 A 1 h E135847 is also available.

EZG 40/4 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 40/4 II/TN-S protects the electrical system from overload. The generator meets the safety requirements 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.
