She was pulling yesterday about 5 mph in mid 2nd gear. When I hit a soft spot, if I didn't wanna raise the disk, I shifted into mid 1st year until clear of the spot spot. She pulls good and the results show. It would be a little better if I could push it a little faster. So the Mahindra 6520 4WD is the bottom end for pulling this disc. She did good even with the drag harrow behind the disc.
