Re: Austin 7 Tractor

7

Re: Re: Austin 7 Tractor

correct.

Re: Austin 7 Tractor

why not 9?

Re: Austin 7 Tractor

ah realised the answer to my own question as I pressed post, duplication, assuming of course that in reality the actual ratios between the 2 boxes are identical rather than just theoretically identical, so it might actually be 9, just only slightly different.
I'll get my coat....

Re: Re: Austin 7 Tractor

.

Oh! you little tease , you!

If one actually does the maths there are a total of ten forward ratios. But three of these are duplicated.

Thus the answer to your original question is indeed seven forward ratios.

Which are :

1 : 1
1.82 : 1
3.25 : 1
3.31 : 1
5.92 : 1
10.56 : 1
18.40 : 1

Well I never. I've learned something here. Clearly somebody should start a Pre-War A7 Tractor Club. (Don't tell me... there's one already is there?)

Re: Austin 7 Tractor

Haha,I hope the starter motor on the ebay tractor works because the crank handle wont!!

Unless the counterbalance is removeable

Re: Austin 7 Tractor

A 2 gearbox tractor used to take part in the PWA7C Peak Trials in the '70s. Surprisingly, you couldn't guarantee it cleared all the sections.
Or maybe it is still puttering up the last one yet....

Re: Re: Austin 7 Tractor

Phil Merris in west Wales had a very nice tractor for years,indeed he may still have it.
