I worked this weekend on a friend's '72 John Deere 2520 Row Crop w/loader. It needs a hydraulic pump. I was doing some carpentry work for him and he was moving a TGI beam suspended from the bucket. Sitting there idling I thought it was rattling a good bit. This guy isn't much on maintenance so I wasn't surprised. Then "TINK" and I notice something drop under the tractor. It was the coupler to the pump had broken. time for some maintenance-free repairs
. It turns out the pump had been leaking, which he knew about. So, this weekend I dismantled it down to the pump. The parts should be here by Wed. I'll upload the pictures of the tractor and edit them in
