Great to see all the JD fans. Two questions: I have a 1980 850, is this the right forum? While cuting grass at my hunting camp it looks like the shear pin broke on the gear box to pully wheel that drives my belly mower belt. My PTO turns but the pully wheel does not. My camp is 75 miles away and I have limited tools. Is there anything special I need to bring and any idea of the size of the shear pin. Can I get at it without a jack? Thanks and great to be aboard.
