Title: Transaxle gearing
Post by: Negrey on March 25, 2020, 12:17:28 am

Gearing options when using a transaxle, Right now I'm setup with a near 1-2 ratio input and 12-1 in top gear to get a total ratio of 6-1. I found another transaxle that had top gear 6-1, (I'm pretty sure) So to achieve the same crank to axle ratio I can go 1-1 on pulleys, Other than the two things that came to mind of benefit, that I can run a significantly smaller engine pulley and my transaxle input will not be over driven.

Is there anything else to be gained from this gearing? any feel differences? any reasons why the overdrive is a better option?

Thanks

Overdrive takes the torque out of the equation, or lessens it,
that keeps from putting too much stress on the gears and
breaking the tranny.

Negrey. 

   You don't say which transaxle you are wanting to use, but I just Posted information on the Peerless 820 and MST transaxles.  You might want to check them out.

Would be a 900 series peerless. I'm reading up on all your posts now. Thanks

Evan, 

   There aren't many parts still available for the 915, 920 or 940 transaxles.  The 930s were quite popular, with many parts still available, and even a few transaxles, but the MST 200-Series was developed to replace the 930s, so if you're using a 930, the right MST will be a bolt-in replacement, with a gear-drive Reverse instead of sprockets-&-chain.   

Respectfully, 
Rodney
