Contractor Kortum – small, but mighty.

ROLLANT 455 / 454 UNIWRAP

When Gunnar Kortum purchased a MARKANT 65 for his contractor business, which he set up in 1991, he could hardly have imagined that the machine would still be an essential component of his vehicle fleet today. In that time, however, the MARKANT has been just one of four CLAAS balers that the highly specialised company in Egeln near Magdeburg has used to serve its customer base. The latest is a UNIWRAP 455, purchased in 2010.

Gunnar Kortum runs the contracting firm together with his son, Martin. Needless to say, such a two-man operation cannot cater to a mass market, but the Kortums have made the best of what is undoubtedly a very challenging business environment and, with their family business, occupy very specific market niches – amongst other things, they aim to keep busy through as much of the year as possible. Targeting these niches with professional technology is part of the company’s approach. With this aim in mind, the duo specialise primarily in beet sowing, vegetation clearance and forage harvesting, while also carrying out mowing and swathing to tie into the harvest chain.

In 1994, the company began baling silage, using a CLAAS VARIANT and a separate wrapper. “We found this a good way to wrap the bales within the shed environment, but we discovered that the silage quality suffered as a result. So it was clear to us that the bales needed to be wrapped immediately after baling and dropped onto the field or stack directly.” Thus, after eight years in the field, the VARIANT made way for a CLAAS ROLLANT UNIWRAP 255 RC baler-wrapper combination. The two contractors used the ROLLANT 225 to bale up to 4,000 bales per year, and were very happy with the machine overall. However, their ROLLANT 255 RC ultimately revealed a few weak points: chain wear was an issue, for instance, while the wrapper arm drive and two baler rollers broke after some eight years in service and more than 30,000 bales produced.

Since 2010, the contracting company has been using a UNIWRAP 455 RC, which the Kortums purchased as a replacement for the ROLLANT 255 RC. They have been extremely impressed by the improvements made to the UNIWRAP 455 RC over its predecessor: “A very sturdy baler! The entire chassis including the wrapper and all chains and rollers have been strengthened, and the chopping performance is fantastic.” Gunnar Kortum adds: “We always try to achieve the highest bale density we can, and harvesting alfalfa demands 100% performance from the baler at all times. In such cases, we don't take any unnecessary risks.” After two complete seasons and 14,132 bales produced, there has been only one repair made to the machine to date. He also praised the excellent configurability of the baler via the CLAAS COMMUNICATOR, particularly in conjunction with the hydraulic MPS PLUS system. “The COMMUNICATOR itself offers a wide range of configuration options, and these have been highly beneficial for our operations – for example, clearing rotor blockages by lowering the chopper housing from the comfort of the cab – that saves precious time”, he says, describing his experience with the UNIWRAP 455 RC. The Kortums deploy the baler behind an ARION 640, one of four CLAAS tractors.

“With the UNIWRAP 455 RC, we’re a fully fledged service provider when it comes to silage harvesting, without having to compromise on area coverage, throughput, bale density or chop quality”, Gunnar Kortum says. “This baler is a good addition to our line-up, and is by no means in 'competition' with the chopper.”
