I just bought a 2007 John Deere 3520 with a 300 CX loader and a 72" belly mower. It has about 800 hours and in great condition. I'm super excited about the new tractor but I also made a slight mistake by not putting pins in the ROPS while pulling in the garage. The ROPS brushed against the rear SCV and I cannot figure out how to reconnect the hose. It seems the line is still under pressure. Any assistance will be greatly appreciated.
