COMPARISON TEST Big

COMPARISON TEST Big Results Excerpt from the profi big baler comparison test For the first time ever, profi has succeeded in gathering big balers from all leading manufacturers in the same field for a comprehensive comparison. In powder-dry conditions, the machines were set to work in a field of wheat straw to give of their best while being monitored by testers. The results are really intriguing, and in this first part of our comparison test we look at bale density, cutting quality, input requirement and throughputs. The following extract from the original article covers the results of the two Krone balers that took part in the test. Buyers of a big baler make their decision primarily on criteria such as service and maintenance, longevity, throughput, bale density, tractor input and quality of cut and whether the machine also makes silage bales. Yet throughput, density, input and quality of cut offer the largest scope for speculation. Putting an end to speculation was exactly our intention when we designed this test. We asked all manufacturers of big balers to send along one of their specimens to the comparison. The requested chamber size was 90cm, because this seems to have become very popular with farmers and contractors, the reason being that these models press more material into fewer bales on every hectare. Be_ sides, many insights from this test can be transferred to the smaller 70cm chamber models.

MF 2270 XD) pulled by a Fendt 939 Vario (291kW/396hp) • John Deere L1534 MaxiCut HC23 pulled by a John Deere 6250R (221kW/300hp) • Krone BigPack 1290 XC pulled by a 1050 Vario (380kW/517hp) • Krone BigPack 1290 HDP VC pulled by a 1050 Vario (380 kW/517hp) • Kuhn LSB 1290 iD OC pulled by a Fendt 936 Vario (269kW/366hp) This means the test group also included two ‘regular-specification balers’ from John Deere and Krone XC which ran alongside the higher-density models – the XL from Case IH, the XD from Fendt and the HDP from Krone. In addition, the test also saw the debut of Kuhn’s brand-new iD model with double plunger. The Claas Quadrant 5300 FC (current year of manufacture) was supplied by a contractor after Claas declined to support our project. The test saw each machine complete four different runs, during which different parameters were measured, and of course we were keen to see the results (see ‘How the measurements were taken’). In the first test, we measured the maximum density, which was determined in TEST RESULTS Krone BP 1290 XC 1290 HDP VC bale density Z BB cutting quality Z BB power requirement BB Z throughput BB BB Compliance with bale length Z B weighing accuracy BB BB = very good; B = good; Z = on average; E = below average; EE = deficient Z 322 profi 11 - 2018

ONLINE VIDEO two separate runs: first the combination was operated at a constant forward speed, and then, in a second run, the priority was on maximum throughput at any forward speed. For the first run, we agreed there and then on a constant forward speed of 12km/hr. The individual densities achieved in this run are listed in the graph ‘Bale densities compared’. The highest density on the first run at constant speed was 171kg/m3, closely followed by 167kg/m3 by the Krone BigPack 1290 HDP VC. CUTTING QUALITY COMPARED Share Feinstrohanteil of fine straw
