My dealer screwed the pooch when thinking he could get a 512 loader on a 4wd tractor. The frame mounts hit the tires.
So after lying to me a couple times on the phone (I knew of the potential issue for a month) and claiming they needed more time to finish plumbing it (4 hoses needed to be threaded on - I saw it on the pallet as delivered. There's 10 minutes of plumbing!), and then claiming it's an 11 hour job to install (Friday the same guy - service manager - said it was 5-6 hours, now up to 11), they still couldn't guarantee it'd be delivered Thursday (this convo was wed)...
Since I either needed more food or was going to unload them for wasting a month on the wrong loader (I originally wanted a 553, but they couldn't get one), I decided to go see what was up with the tractor at around 2pm wed (tractor was supposed to be done tuesday and returned btw). Upon walking in the door, the service manager looked like he'd seen a ghost - it was "come to Jesus" time and he knew it. So he took me back and showed how the one mount hit the tire, and they were getting a different mount delivered in the morning. I explained to him it still wouldn't work since Deere doesn't support that loader on 4wd models. He questioned where I got that info, and I told him it's in bold print on the loaders manual "two wheel drive tractors." I then told him I wanted out of the purchase agreement.
They agreed to let me walk, but wouldn't give me anything in writing claiming they needed paperwork from Deere to do that. I was livid, but held my composure (barely) and left.
