Drawbar on Challenger 2 designed portable for not to have any handicap or problem. While installing the machine to the tractor, by moving the side arms; you will have any problem or trouble for balancing the machine and fitting the holes.
Adjustable Wheel System
Row independent maize chopper is a machine, heavier than 1000 kg. To carry all the weight on the arms of tractor can be a risk especially for small tractors. To carry the weight of the machine, an adjustable wheel system placed to the tractor. Thanks to this system the weight of machine can be share between the tractor and wheel, and the machine don’t encounter with the soil on the rough terrain.

Mustafa GÖBEKÇI / Incirliova, AYDIN,

"Diğer marka makinelerle de çok çalıştım. X marka bir makine ile 115 bg lik bir traktöre bağladığımda aldığım performansı Çelikel ile 90 bg lik bir traktörle aldım. Ölçtüm, 90 bg lik bir traktörle 7 km hızı geçti. Diğer markalarla kıyasladığımda çok iyi bir performans. Piyasaya çalışan bir çiftçi olduğum için yakıt çok önemli. Çelikel ile çalışmaya başladığımdan beri yakıt tüketimi % 10 oranında düştü. Bizim buralarda silaj işi 20 – 30 yıldır yapılır. Tabiri caizse biz bu makinelerin ciğerini biliriz. Çelikel makineyi denemeye getirdi. Biz makinenin iyi olup olmadığını sesinden anlarız. Makine iyi değilse traktörün sesini bastırır. Traktörümüzün makine yüzünden zarar görmesini istemeyiz. Ama Çelikel’ i traktöre koştuğumuz zaman tek duyulan traktörün sesiydi. Traktör makine yokmuş gibi çalıştı. Makinenin iyi olduğunu anladık."
