"JENZ builds machines the way I would have built them"

Ulrich Laschütza and his HEM 582 Z with hydraulic blower...

Rödinghausen. Ulrich Laschütza just loves agricultural machine technology. This is the reason that Mr Laschütza, now 44, decided not to study after his A-levels but to train as an agricultural machinery mechanic. Once he had finished this, he qualified in his master's diploma. Mr Laschütza, who comes from Rödinghausen, had already gone self-employed at the age of 18 as a private contractor with a combine harvester.

"My grandpa was a self-employed carpenter and had four daughters, of whom one was my mother. In other words he never had a successor, so I was able to use his workshop for my company" said Mr Laschütza. The founding took place more than 25 years ago, and nowadays Laschütza GmbH operates as a modern commercial and service company. Purchase and sales of tractors andagricultural machines, a workshop and the private contracting company are the business areas. Nowadays, Mr Laschütza spends a lot of time in the office "which is a shame, because I miss the dirty hands". The workshop is managed by Björn Kammann, and the Claas Xerion 3.800 with the new JENZ HEM 582 Z mobile chip is driven by Andreas Bartelborth. Both are employed by Ulrich Laschütza.

The company uses the mobile chipper to produce woodchippings as a private contractor, but also to trade in woodchippings for its own purposes. For example, Ulrich Laschütza operates the woodchipping heater (only for boiler operation) at Rödinghausen Comprehensive School and the primary school with its sports hall in Bruchmühlen. "We only sell the schools heat. The boiler unit belongs to us, the heating system itself belongs to the schools" said Mr Laschütza.

Quality plays an ever-increasing role in terms of woodchippings, which was the reason why why Ulrich Laschütza and Bernd Ruhe, JENZ's sales manager for northern Germany, came together to discuss an idea for an experiment. Together with the JENZ construction department, they have developed a mobile chipper with hydraulic fan based on an HEM 582 Z. To do this a large fan originating from the HEM 820 Z was used, and the hydraulic drive was used to regulate the rotating speed of the vanes during operation variably between 450 and 1050 rpm.

A further technical refinement is the displacement pump with constant motor. This means that the ejected material remains at a uniform volume even if the rotor changes its speed, for example when different densities of standing timber have to be chipped. The result is almost as good as a conveyor belt in terms of outfeed technology. The woodchipping quality increases because the optimised fan speed damages less chippings, which means that the zero portion reduces. Dispersion when blowing out the woodchippings reduces - not so much gets thrown past the target. Last of all, this innovation reduces wear costs. Ulrich Laschütza can only conjecture whether regulated fan operation also reduces the Claas Xerion 3.800 drive machine's fuel costs. "At the moment I don't have enough data material to make a reliable statement" he said. One thing he can say, however, is that the technology works.

Since he is an agricultural master mechanic, Ulrich Laschütza is capable of carrying out discussions with JENZ engineers at eye level. He was part of the team right from the beginning during construction, was able to input his proposals and ideas and always felt welcome. "You can really tell that the people at JENZ are keen on their work. JENZ builds the machines the way I would have built them" commended Mr Laschütza, who now fosters an almost amicable relationship with service technician Bernd Ruhe. And this is why the machine wasn't just handed over in January 2013, but "launched" with a bottle of bubbly, as Bernd Ruhe says. After that, he donated a barrel of beer, and Ulrich Laschütza donated the sausages. And it's almost sure that he showed Bernd Ruhe his collection of almost 30 historic tractors during the celebrations. Ulrich Laschütza has collected those over the the years - because he just loves agricultural machinery.
