Findings on my mystery attachment

Jason the Red · Nov 9, 2009

OK. Here"s what I learned.

I performed the test of my mystery attachment just now and me findings were not exactly as I had expected. With Transmission in neutral and clutch pressed in, I engaged lever on attachment, released clutch and tractor took off like a bat out of hell, until I stopped it by pressing clutch back in. I did not let it run out to see the top speed but could tell it would probably out run road gear.
Now for my question. What crazy person would want to run faster than 15 MPH on a tricycle tractor? And furthermore what, if any, application would need to run that fast? The tractor has an interesting history but I don"t know how it was used in the field. When I purchased it the rear tires were offset which leads me to believe it was used on terraces somewhat. Anyway I just thought I would report my findings and try to pry some more knowledge from you folks. Thanks again

geez, im not sure actually, If you want to sell it however let me know haha,ill even give you a belt pully, My guess that it is a high range that lets you get a little more range becuase 1-4 are kind of close, but thats my best guess

Can't say for sure how fast an M will go with a Heisler OD, but they are pretty fast... over 20MPH. Dad had a 1940 A JD with a Behlen 5/6th gears and it would run well over 20MPH also. Not all that unusual in tricycle tractors it seems.
Neighbor kid, who's dad had a Heisler OD M, and I used to argue all the time about which was faster, but we never got the chance to find out... probably wouldn't be alive today if we had. :lol:

I wouls jack up one wheel and block it (and the tractor) so it is sturdy and safe. Then I would let it Idle and put it in high gear. let out the clutch and then count the wheel revolutions in one minute. Then do the same with the auxillary gear running. This will tell the story W/O being unreasonable. JimN

I am guessing that the constant mesh gear is engaging a compound gear on one shaft which is engaging another gear and shaft. That secondary shaft and gear is engaging the IH sliding 4th gear. You are overdriving the mainshaft of the transmission.

Cool. Let me know if you ever want to sell it. I always wanted to drive my H down the interstate and pass everyone.

Hmm, didn't see that one coming...

Hopefully you had the tractor pointed in a harmless direction.

I can see wanting to go faster when traveling between farms and fields.

I remember reading about tractors that were used for mowing highways, sometime had high speed gears.

I have a 1951 Farmall M with a Heisler 9 speed. It has no effect on 5th gear and adds the 4 additional gears between the standard 4th and 5th gears. Your post mentions a Heisler Overdrive and that may have been something different then the 9 speed setup on my tractor. We had a 1952 8N Ford when I was a kid that had a Sherman transmission and it in fact in high range did about double the standard 4th highway gear. I had the tractor in town one day to get new rear tires installed and picked it up after high school classes. I caught the school bus outside of town a few miles and passed it going up a hill with all the kids hanging out the windows. The bus was one of those late 1940's Chevy 6's which had to get in low gears for anything other then being on the flat or going downhill. But I believe that Ford 8N would come close to 30 mph though. It's a wonder we did survive some of the stuff we pulled as kids, Hal.

Aww that is not too fast for a tricycle tractor.

I have an Avery A that has been clocked over 45.

My FIL put a Datsun 60 HP engine on it with the Datsun tranny in front of the Avery tranny. Darned thing has at least 4 reverse speeds now and 12 forward forward ones I think.
