Yes, im getting into racing lawnmowers. :mask:
I am looking to change the pulleys but i have a problem.
i have the pulley on the motor and the pully on the tranny.
But, i have another pulley in the middle of the two so that the belt from the engine hooks to in and so does the one on the tranny.
Do i leave the middle pulley the same and change the front to big and back to small?
Thanks for the help. :D :D

What you're describing is a variable speed. Not the best choice for making a fast mower. First off, the vari-drive itself is fine for mowing, but will eat belts left and right if you over-drive it. Second the transaxle in your mower (assuming it's a single speed, not a dual range from a GT) is not a particularly strong transaxle when it comes to abuse. Another issue is the 20:1 reduction.

I'd suggest ditching the driveline you have now and replacing it with a Peerless manual shift transaxle. Even better would be to use a live axle and a Peerless transmission.

Just how fast do you want this thing to go?

[put the small pully on the motor and the big pully on the tranny it should go pretty fast,faster than stock its probley cheaper than putting a manual shifter on it::cool:

Smaller on the crank will slow it down, not speed it up.
As will larger on the transaxle. ;)
