I've had mine for 2 seasons and really like it. Driving over the snow before the blower gets to the snow is not a problem. It also allows me to keep the FEL on the tractor in the event I need to push something to the side. I'm still working on getting the proper angle and height while using it so I don't blow all of my gravel into the woods , but other than that, it's been great. Hope this helps.
HI I would look at the Agro trend 72'' snowblower for your JD3320 i'ts a good fit for your tractor Elmira farm service brings them in JD green. $1900.00 apox. I just bought one for my JD2520 I know it's over kill, but I think it will handel it.
