Driveline / How fast can I spin a stock craftsman transaxle?
« on: March 24, 2021, 12:11:02 am »
I have what I believe is a DANA 4360-140 transaxle, with the stock 3.5 inch pulley in the front, and a 3 incher in the back. It's going around 14mph with the current setup, but I'd like to swap to a 5.5 in the front, and a 2.05 in the back, which works out to roughly 35mph. Thing is, I know the stock transaxle isn't meant to go 9000rpm, but it's already going about 3 times as fast as stock.

Will the stock transaxle hold up? Is there anything I need to do to make it tougher?

Newcomers / Craftsman riding mower with B&S 287707
« on: March 01, 2021, 01:02:00 am »
Hello everyone, i'm new here but i've seen lots of lawnmower racing and I want in!

My donor mower is an old craftsman with a 6 speed and a B&S 287707 14.5hp engine. I got the engine in working shape, and dropped the mower deck. I switched the transaxle pulley from a 9 incher to a 3 incher, and tuned up the brakes on the thing.

I'd like to know where to go from here, the engine def still needs some work (I can handle), but I want to make the transaxle as solid as possible before I run it super fast. Where should I start with this mower? How can I upgrade the brakes, and get the throttle mounted somewhere better?
