I have a B2320 with around 140 hours that is leaking hydraulic underneath the floor pan near where the front shaft goes into the transmission. When I start the tractor there is a steady flow that runs out. I showed the Dealer with a video on my I Pad and they thought it was too much leakage for the seal to be damaged, more likely a hydraulic line above. It's hard to get a mirror up above in such a tight spot so they sugested taking off the fenders and floor pan. Is this a difficult job on a 2012 B Series? Any other ideas where this leak is coming from? I'll try to post a view. Thanks in advance!
