i have a 1960's jacobsen chief 1000 with a 3 speed transmission. today i went to go shift it and i could not find the gears its all sloppy like. after a while i found the gears very tricky to find but i can get them. i am supposed to pull in a tractor pull in a week so if you great people could help me fix the problem or lead me to the parts needed that would be so great thank you so much!

I would imagine your shifters rollpin is sheared. It is in the shift lever just where it goes into the tranny. Pull the shift boot back and see if there is a set screw to release the shifter and slide it out of the tranny. You should be able to see whats wrong and whats needed from there. I wouldn't recommend pulling it like that even though the tractor moves like its in gear it is likely only halfway in and could very easily break something when a load is put on it. Let us know how you get along.

Where's my manners? :toilethead:


If it is the rollpin, they are readily available from your local hardware store. Take your shifter with you so you can get one that fits tight. The rollpin serves as a hinge or pivot point for the shifter. GOOD LUCK!!

Welcome to the forum! I'm guessing the pin needs replaced also.

Here's a link to the parts manual for it:
