Thanks. The builder has spent a good bit of time on this. Notice all the holes in the frame have been filled. The price for the body was just too good a deal to pass up.

Getting closer to being done.

Tractor's looking great!, thanks for the updates.

Well, I got the tractor back from the builder yesterday. Spent today adjusting the seat and stuff. AAAnd installing more stickers. Here are a few pics. The skull stickers came from Greece. Actually ordered a second set to make sure I have spares.

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.

With that motor and setup you have you definitely have the need for speed! With similar tractors in our club we run 20-22 gears. Mike:biggrin2:

The Firestone's really need to be cut to perform well.

I agree with Stacey that the stones need to be cut but also you have to play with gearing with each tire and balance to really get a feel for each tire.

The first run with the Firestones was 125 feet. I upped the air pressure from 3 lbs to 7 lbs for the second run. The second try they went 140 feet so there is room for improvement. The AT101s went 150 feet on the first try with 7 lbs of air. Really surprised me.

I have been a bit skeptical about the 15/17 gear set up. With my engine, I tried a 23% overdrive. Too high. The 15/17 works just fine with a 13 tooth pinion and my setup. I can pull in 3rd gear on most tracks and 2nd on sticky tracks.

Bought some of the new Lawntechs from Midwest. They are 81.5 inches around so they fit under the fenders without mods. They beat a set of super lugs by almost 50 feet. Had a good day pulling.

Got a look today. The Lawntechs rubbed on the inside of the fender and the edge of the fender under load. Moved the fenders up an inch. Going to add another 1/4"to the wheel spacers.
