They are both Simplicities, just one is badged a Massey. It will be a K66L which has traction control and a locking diff. The Landlord is a beefier machine with hydro lift and steering but more hours on the clock. While the Massey doesn't have the hydro lift or steering it also means they won't break on you. If you search on my name you can view my postings on my Conquest. It is the exact machine the Massey is, 16HP, K66L, 44" Deck. I bought it from a dealer in WI and had it shipped, I've done a bunch of service on it and posted most of it up here with pictures.
