We have a 199? 14hp single cylinder Manual trans. We have converted it into a pulling tractor for our grandkids.
It pops out of 2nd gear. We thought it was a lose set screw, but once we tightened it up it did it again. Any ideas?

Please post your units model numbers so we can see which transmission you have.

My husband found a broken pin and he replaced it and it seems to have worked. Thank you so much
