What ploughs are you guys using?If you can pull 4 furrows with 100hp sumat like a TM150, 155, 165 would be ideal.
they will lift a heavy 6 furrow not bother as long as the front has plenty weight on it.
Proper land workhorse .Case Magnum
50 series valmet
A shear coupling from the gearbox output shaft to the pinion shaft iirc.I've had a 35X with retractable strakes on struggling to pull 2 x 12" furrows here - Down into 1st gear which I was told was protected by a shear pin.....
10" furrows--7" deep. saw that outfit demonstrating 5+yrs ago.72hp is more than enough for 6 furrows
Love those old style tractor promotion clips.72hp is more than enough for 6 furrows
