Farmall F-20 Overdrive

Andy Motteberg · Oct 5, 2008

Hi all, here is a picture of the overdrive on my F-20. Could anyone tell me who made this overdrive? I'm thinking maybe a Heisler, but I'm not sure. If anyone could give me any info on this, I'd appreciate it.

Thanks,
Andy

Andy,

That is a road gear only not a overdrive, to work it put your trans. in neutral than shift that road gear in it's a 5th gear. I have three 20's one is a road gear like your and the other two have overdrives in them. Overdrives step up all the gears that gives you 8 speeds forward and 2 in reverse. It should run about 12 mph in road gear have fun be safe.

This is a Behlen, it will give you a road gear only! Heisler is cast iron & gives you a range of 8 forward gears & 2 reverse.

Thanks, I knew I only get high gear, just wanted to know who manufactured it.
