I'd think about using the 8 ball mains

OK. I ordered the 15/17 gear set, a 13 tooth pinion, and a billet pinion carrier. My transmission has a heavy fine tooth carrier, not the 2 piece. I have a 2 piece carrier. When I get the transmission rebuilt, do I need to install the two piece carrier? The engine will have no more than 20 hp. Is there anything else I need to do to the transmission given 20 hp.?

in my opinion I'd put the 2 piece in. save the other for a second tractor. also weld and reinforce your 2-3 shift fork

The deal from Midwest includes a new 2-3 fork, so I am good there. Thanks

aftermarket or stock? if its a stock one it needs work.

Aftermarket.

I am thinking about buying some cut tires. Our local track is soft until you dig down about three inches, then it gets hard. What is the best tire to buy for hard or soft tracks for a 4000 rpm tractor with about 20 hp.?

What size and style are you required to use?

26x12 professional pulling tires. Vogel has too many choices. The track is definitely not a biting track. Usually very dusty, dry, and loose. Once you dig past that it is very hard.

there's allot of choices in tires. I don't believe any of them work decent "out of the box" . they all need cutting or hardening or both to get the most out of them. right now the Nichols Edge tires are about the best you can get if they are cut properly. before that the original Lawn Tec L or S tires were the hot ticket. the new Lawn Tecs show hope but when tested heads up to a Edge tire the Edge seams to preform better. I've not had much luck with Vogel tires. most guys that run them like the 08's or 11's if I was going run a Vogel tire I'd chose the Riot , its a radial tire that is a copy of the 11. We've been watching them pretty close and they seam like a nice tire. Vogel says the preform nice "out of the box" but you talk to real good tire cutters and they have their own opinions.
there's allot of things to keep in mind for tire cutting that most people don't think of. tire angle: anywhere fro 23 deg to 10 deg. snub nose tires; 2 inch snub to 3 in snub. lug front angle and side reliefs. and then you have the multi angle Edge. most people that run Edge tires run a 17 deg lug with side reliefs and they leave the compound angle part of the lug on.
I wish we had the money spent on tires that just didn't work or worked on only 1 type of track and the wasted cuts.
it would be interesting to hear others opinion's on this
