Efﬁciency and safety gains for Lincs contractor maize foraging season when moisture contents are higher and will compact better,” says David. “Also for rye and grass there will be a far greater benefit.” He has been pleased so far: “We have been towing it behind an Arion 650 with air-brakes and the hydraulic drawbar and the swivel eye means it runs really well on the road. The Kompactor trailer is a branch out for Hi-Spec Engineering which is best known for its high-capacity paddle or auger type diet feeders, vacuum tankers and muck spreaders. Kompactor is available in four sizes – the K30 (18ft), K33 (20ft), K36 (22ft) and K40 (24ft). A demount version is also available, which enables the trailer body to be swapped for a Hi-Spec vacuum tanker body. Emptying the Kompactor involves raising the tailgate, then fully extending the headboard. Depending on load, the trailer can be empty within 30 seconds. The load is pushed off so the trailer body does not need to be tipped. This, alongside the push-off mechanism and low centre or gravity reduces or removes many of the risks of tipper trailers, says Hi-Spec. The push-off appeals to David who

has five 600t grain stores which don’t have access for a tipper trailer so grain usually has to be tipped outside and bucketed in. “With the Kompactor we will just be able to back in and push the grain out, which will be far easier and quicker,” says David. The Kompactor is lighter in weight than a conventional trailer. As standard all models feature commercial running gear, air/hydraulic braking and a hydraulically sprung drawbar, through which all the hydraulic and electric lines are routed, LED lighting and reversing light. Options include

With more than 3,000ha of feed crops to harvest for seven different anaerobic digestion plants, efficiency is key for Lincolnshire contractor David Fox. David, who is based near Scunthorpe, harvests some 2,000ha of maize, 480ha of whole crop rye, 480ha of grass and 80ha of whole crop wheat. He runs two Claas forage harvesters and a fleet of 14 trailers (16t). Looking for ways to increase trailer capacity led him to consider alternatives and in particular the Hi-Spec K36 Kompactor compaction/ push-off trailer. The key feature of the Kompactor is the hydraulically-operated headboard which is powered by a three-stage hydraulic ram. With the tailgate shut, the headboard can be used to compact material such as grass or maize silage, which can increase load by up to 80 per cent compared to a conventional trailer. However, due to its size the Kompactor trailer is also suited for transporting bulky materials, such as woodchip or grain. “On average, a trailer will hold around 13–14t but with the Kompactor we can increase the load for the same size trailer, especially earlier in the
