Today we had a test and tune. I had the chance to compare my 26" Firestone 23 Degrees against my AT101s. The track was damp and biting. The AT101s killed the Firestones by 10 feet in the same gear. There was a lot of interest in the AT101s after that. Disappointed me as the Firestones cost a lot more and looked like they would do better. They needed a higher gear.
The tractor did well. Gearing is too low. RPMs did not drop at all using a 13 tooth top gear and a 17 tooth high gear. I am adding 23% overdrive to bump high gear up to 19.5 tooth.
I will keep the Firestones for now. They might work better on a loose track. Next I will be trying a pair of Vogel TT26" against the AT101s.
