Just a heads up when Massey updated the GC hydraulic quick connect couplers on the loader (2017-2018) they created a bit of a compatibility problem. If you happen to upgrade your pre 2017 tractor to a newer one - your older snowblower with the smaller fittings wont plug in! And of course I just realized this and its going to snow tomorow. Haha. Just figured i would share my whoops incase anyone else has a similar situation with the 2 different size fittings.
