6-speed and 8-speed question

[Rogue 0]

This may sound silly... But after looking at the tranny manuals I'm having trouble seeing a difference between the following transmissions. Can anyone give me some insight as to why one is referred to as a 6speed and the other an 8 when the ratio's appear to be the same. Also, is there a "better of the two scenario"?

Thank you for any help you may be.

Starting in 1973, high and low reverse were counted as "speeds" (no one ever said in what direction "speeds" had to be ) for a grand total of 8.

It's my guess that it was a marketing ploy by WH and nothing more. ("Our transmission has more speeds than brand X.")

With proper maintenance, the most reliable and durable manual transaxle is the 8 speed Uni-Drive with 1 1/8" axles and the 8 pinion differential. They are normally found in the majority of the C series tractors, the 400/500 series and the '76/'77 B-60/80/100 models.

Thanks TT I very much appreciate the explaination. One more question... Do you happen to know if the 5060 6-speed is problematic?

If they are properly maintained and used normally (no heavy "jerking" from pulling) they have a very long lifespan. I know of quite a few from the late 60's that are still going strong!

The biggest problem with all 6 & 8 speed transaxles is shifting the range selector without completely stopping which can result in gear damage and/or a bent/broken shift fork.
