Jubliee transmission option?

The tractor to me looked like it was multiple tractors put together but the NAA serial number on the bellhousing and the sheetmetal looked like a NAA. Did these tractors have many options that could be ordered when purchasing them new?

The shifting handle located above the clutch pedal on the left side is bolted on on the outside. I guess that make this a "Sherman 3-speed combo". What are the advantages of this tranny that made buyers go to the trouble of purchasing this option? Is it a better transmission than the basic transmission that came out on the tractor from the factory? Would this cause my tractor to be seen as not being a factory original? I do like this transmission because it runs so smooth.

I stopped to see other tractor that started this discussion. The seat is the Monroe seat that Dan pictured. The levers that are missing from under the seat deal with the brakes. There is also a 4" lever located under the right front edge of the seat that is missing. There is a 2" dia by approx 6" long spring that is missing on that tractor also. Other brackets appear to be missing.

I now know that my tractor is the one that is correct and that the tractor on the lot is the one that is NOT complete and original. My goal was to develop that understanding.

The 'Combination' trans is called a "3 speed" because it gives you 3 'ranges' of gears. Overdrive/(hi), underdrive/(lo), and straight thru/(regular or standard). 12 forward AND 3 reverse in your Jube. Do this: pull the handle back/up as far as it will go to check your high range. Forward/down as FAR as it will go will be 'LO' range. NOW, fiddle with it to find neutral right in the middle between these 2 positions and pull OUT/away from the housing while wiggling. It should slide out about an inch. When it does, pull back/up/toward the seat and you will be in 'regular' 4 speed gearing. Sort of a backwards 'h' just like an old car floor shift. This last position 'bypasses' the Sherman and allows you to use the regular 4 speed trans as if the Sherman wasn't even there. Cool, eh? Hope this helps.

Good luck and tractor SAFE!,

Do you know if this adds value to the tractor or does it deduct value? Would the tractor be considered original to a collector or a tractor club? I plan on keeping it for a long time to mow with but I just like to know what I have.

Right side under the seat had a 3" draft/position handle, and then back from that a bigger.. say.. 7" handle in a quadrant that was the lift control.

Take a pic if yuo think it looks different.

The Sherman auxillery transmission was a dealer installed option. There are more without this option than with it. The stock setup did have the exhaust routed underneath the tractor. Also, there are a few aftermarket and dealer installed seat options, one is the Rest-O-Ride seat I have on my NAA (in this pic).

HTH,

Great looking seat!! The seat that was on the tractor I am talking about actually looked like a car spring that was wound tighter at the bottom than at the top. The seat sat directly on top of the spring. I assume it is probably an after market (or home-made). It certainly didn't look as nice as your picture shows. Is your NAA restored? More pics are always appreciated.

My Jubliee has the exhaust turned up and I thought it was factory. That is why I am asking the questions. I don't know what is factory and what is not. It is funny, since I bought this tractor and found this web site I feel like a kid in a club (or candy store). I throughly enjoy it.

Thanks for the compliment, I find old rusted out stuff at my local antique boneyard and fix it up - it is just my hobby and escape from city life. It sounds like you may be describing a Monroe EZ-Ride seat. Here is one I fixed up for my 48 8N trailer queen. They were only made for the 9N and 8N tractors, but the NAA bolts the seat spring the same way as an 8N does, so I guess you might be able to rig something to get it over the hydraulic connections on top of the NAA lift cover(?)

So, you say you want to see more pics of my NAA :-) Click on the link below to a website I put up on my NAA Project Rustbucket, taking it from a scrap heap to a working tractor - with over 200 pics and commentary on each one. That will burn through an evening.

I'm not sure what all was available for the NAA.. but at least for the 8n, there were many brands.. hupp.. etc..

According to John Smiths site, the combo was the most popular, etc.

Considering the step up came out way befor ethe combo.. I'm sure there are a ton of them around... My 2n has a step up.
