Xtreme Mower Mayhem

i have a 12.5 motor with 4 inch on it and dont know which pulley on the tranaxle i have a 6inch 7in 8in 9 in and a 4 in and the tranaxle is a peerless for best for going mudding and stay in 20-30mph range

use the 4 inch its good combo 1:1 it gets you to about 20 mph and any higher will just slow it down and it still allows you to mudd

i had a four inch on the back with a two on the front and i was doing 20 already

then i would say keep them the same if you want it to go 20-30

Keep the same, just different size tires.
