1:1 is a good ratio, only thing is dont go smaller then 3" trans pulley - the belt wont have enough wrap around it to spin it correctly.

Thats the problem i have on my lawn tractor, the belt will just slip, at first i thought the belt was loose but then you can see the belt slipping on the pulley.

If you want around 15mph a 1:1 is the way to go.

Its hit or miss. I know most Peerless transaxles I have swapped ran 5/8, while MTD FNR transaxles used 1/2" bore.

You could try this, CornishMorgan sent me it although I havent used it yet. http://www.baumhydraulics.com/calculators/belt_length.htm

A rope would work too. FearlessFront has a tutorial on how to do it.

If your tractor is a twin, (please be a twin) Then you have about the same year as me, and it IS a 1/2
