310 Starter troubles

[mtg6251]

I have been through 3 rebuilt John Deere starters in the last 3 years on my John Deere 310(late 70's). They work fine at first but after a few months I push the start button and it just clicks. If I keep hitting it eventually it cranks. No problem starting once it cranks.I replaced the positive lead to the starter but not the ground wire from battery to frame , also replace the start button.Last time I had a John Deere mechanic out who replaced the starter again last summer and said he found nothing else wrong with the system.But true to form it worked fine for a few months and same troubles.And couldn't get it to start this winter and could use it to plow. IS it possible that theses rebuilt starter are just crummy? Any suggestions would be greatly appreciated.

Have a similar problem with my IH. It will click, click, click ... and then engage. Then there is times it starts first push. Gets annoying pretty fast. There is either just a bad place in the starter (its original like much of the tractor) or there is a bad ground somewhere.
