122 Started Right Up

Nailhead · #1 03-15-2016, 12:17 PM

i was a given a 122 last fall by a customer, and have put quite a bit of work cleaning/updating the fuel system, replacing the water emulsion in the gear box, replacing rear tires, among other things.

After finally fabricating a choke cable bracket, it was ready for startup, so that's what I did.

Some bugs flew out of the exhaust, a few pops, and it did indeed start.

The clutch was frozen after sitting in the weather. Once I got it freed up, I could get it into gear, but only by using my heel to push the pedal flat against the footrest. I adjusted the linkage twice, but it still engages way too low in the pedal stroke.

It ran great after a few carb adjustments, and I drove it around a bit.

It has the turning radius of a subcompact car, though; is that right?

Congratulations on the 122, glad to hear things are going your way.

More than likely it will turn sharper to the left, some believe they intentionally "set" them that way so it would be easier to mow close on the left side of the tractor.

You can adjust that out if you like, set the front wheels straight, disconnect the drag link, turn the steering wheel all the way each way and find the middle, then adjust the tie rod ends to go back into their respective holes without moving the steering wheel or the front tires.

If you can't adjust your clutch pedal to get it up higher, the teaser spring on your drive shaft may be gone, or the lever could be badly worn or bent causing your pedal to be so low. Here's a link to an exploded view of your clutch, you can check it against what you have to make sure everything is there and as it should be.

Good luck.

Love how easy it can be to bring these back from "the dead."

Good luck.

Thanks very much for the info.

I'm not going to mess with that steering if there isn't a way to give it a little more lock. I've got enough to do, what with the mower deck in pieces on my shop floor.

After giving the clutch mechanism a second look, I adjusted the pedal freeplay to 3/16" per the chassis manual. The teaser spring appears to be there & in good shape, and the pedal & linkage don't appear to be worn. The freeplay was at about 7/16" previously. I didn't have a chance to test it, but it has to be better than it was.
