I'm learning the hard way about these tractors. I bought a 2006 3320 that I knew didn't have the mid PTO drive. One of the reasons for buying the tractor was to use it to mow our 3 acres. So I bought the drive kit from the local Deere dealer and installed it. Not a bad job. Probably took about 4 hours with my engineer son helping. After getting it all installed and checked out, I finally realized that every tractor doesn't come with a lifting mechanism. I had already bought a deck separately from a guy who had it on a 3720, so I figured it would fit. And it will once I get a lift kit installed on it. And that's where I need some help. Does Deere have a lift kit that includes all the parts? If I have to buy all the parts individually, it's going to be a really expensive list of parts. I'm looking for some help on this. Does anyone out there have an unused kit? or would be willing to sell a couple of the brackets that are so expensive when new? I'm looking for the parts that mount to the tractor, not the ones that come off when the deck is removed.
