D-15's 3rd gear was very sound-never slipped out of gear. Permitted a nephew to rake some hay this summer without instrucing him to use the foot clutch to shift gears. The tractor has been returned and it slips out of 3rd gear. Can the gear be damaged with just a few bad shiftings? Should I check on some adjustment before I replace the gear? Thanks Marlyn

Marlyn, Easiest way to tell is pull side cover off.Check your fork first, then look at shifting collar and gear.You should be able to tell if collar and or gear is bad. Might possibly put temporary fix by moving detent on rail. HTH Tracy Martin

I doubt he could have caused the gears to grind down enough to make a perfectly sound transmission start jumping with just a little use. You can bend a shift fork in a shift or 2 if you are determined enough to do so, however...

Mine was pretty bad and I modified the rail 3 years ago and hadn't had any trouble since and mine gets used quite a bit. But if he was pretty rough on it he could have sprung the fork a little. It wouldn't have to bend but a few thousandth's to make it start falling out of gear. You can move the detents on the rail about 1/16 inch pretty easy. I have been thinking of making up some replacement rails that you could change out but haven't got started yet. I have a D14 in the shop to do that to this week.JP

I agree on bending the rail...3rd gear is the most abused of them all and it's a wonder you're just now having problems. If the gear is still silent with no clacking or clicking it's doubtful the cog was hurt. My D15II's 3rd gear has been lightly clacking for 25 years and it still doesn't jump out of gear. Good luck!
