I installed my Heisler overdrive on the F-12 last night. I've been taking it out driving through some pasture and crop ground behind my house. I still have yet to get my 40" rear tires purchased so I'm running on steel. Let's just say it's made for a wild ride!!
I took my GPS out to see what speeds I'm getting. Everything is exactly what I had figured from the posted speeds books. With the overdrive in high 1st gear is running 5 mph 2nd 8-9 mph and 3rd 14-15 mph.
I expect these numbers to be a little higher when I get the tires and I'm on pavement and not running through mud. The tractor isn't lacking for power at all and I still have yet to try some modifications to my carb and tweak my throttle linkage some.
