The Hesston 1375 isn’t only the newest of the 1300 series by Massey Ferguson, it’s also the biggest. Weighing in at over 7000lbs, the centre-pivot mower conditioner is 4.6m (15’3?) wide.
The machine uses 10 rotary discs, each with 10 free-swinging reversible knives, to cut crops at 1.3 to 3? in height. And just when you thought the rock-skipping knives couldn’t be any cooler, you find out that they can reach speeds up to 176 mph at 3000 rpm.
Mowing at speeds around 9mph, the unit has to keep up to avoid plugging. And, according to Dave Orr of Full Line Ag, it avoids plugging through the high speed of the discs, and the unique way it is moved away from the edges.
In this video, filmed at Ag in Motion, Dave Orr of Full Line Ag in Saskatoon talks about the 1375, including a brief explanation on how it is able to reach such high speeds without plugging.
