So I helped a buddy rip a stump out of the ground yesterday. Not really big so I didn't think it would be a problem. Put it in 4 low, dropped it in reverse gave her a little juice and she yanked it right out. No problem. Then I put it back into 2wd and as soon as I dropped it into drive it made a wierd grinding ticking noise. I threw it into neutral and it stopped. Haven't heard it since but I don't know what it was or where it came from. Any ideas?
