Can't compare gear to HST. Gear wins every time!

It is surprising that the much lighter
B7510 could out push the 50% heavier JD. Makes sense it if was a poorly designed HST transmission that couldn't put all the power down. I'm guessing that if he was spinning sometimes and bogging other times the difference was if he was adding weight or removing it from the tires with the FEL. Still, he couldn't put all the power down when pressuring the tires with the FEL and that is just poor design. I've heard of several HSTs having that problem years back. You don't tend to hear about it anymore (a assume they figured it out and fixed it) I had a similar tractor to the
B7510. It was a Kioti LB1914. 19 to 21 hp depending where you look. Would run out of engine in 4th gear. Would spin all 4 tires in 3rd gear ballasted to 3800 pounds (2100 pound bare tractor).
