The diffusers are mounted on a tubular frame designed and adaptable to the front of the straddle. The height of the diffusers is hydraulically adjustable. The two diffusers have a working width of Ø50 cm each. Perfectly adapted and designed for row crops (vineyards, nurseries, etc.), the heat diffusers retract in front of an obstacle and return to their initial position. The carrier can transport 2 racks of 4 P35 bottles, i.e. 280 kg of gas.
