The innovative drive system adapts its operation automatically to all variations of operating conditions, contributing to the gun's great flexibility. The drive system is mounted on a strong and rigid drive arm.

The gun's slow, steady rotation with greatly reduced vibration in both directions has the advantage that the carts of reel hose machines stay straight on track and the risk of tip-over is reduced. This smooth operation is suitable for all irrigation systems, especially as an end gun on center pivots where stress on the end boom is kept to a minimum.

The unique drive system allows a better stream diffusion. Over the whole pressure range its operation is excellent. An additional advantage of the drive system is that at the start-up procedure of the gun, the normally compact stream is dispersed into a spray before the gun is set in motion. This greatly reduces furrows and run-off. Because of the Twin's superior distribution close to the gun, spreader nozzles are not needed.
