Trailer PRONAR T682

PRONAR trailer T682 (T682/1) is construction of one of the largest agricultural trailers on the market today. Load capacity of 21 tons meets the requirements of large farms. The trailer is fully automatic – hydraulic rear wall closing by clamping hooks ensures trouble-free operation. Hydraulic power system of the trailer allows it to aggregate with tractors of smaller capacity of hydraulic pumps. Self-steered swivel axle system improves handling, increases safety and significantly reduces tire wear. Minimum tractor power with which it can be aggregated is approx. 180 hp. Excellent price-performance ratio.
