The Mott is most likely an 88" cut Super Heavy Duty model with the 4 1/2" dia. cutter shaft. It will cut a lawn just fine and pretty much any type of grass and weeds you would ever encounter. They do make fine cut models but unless you're on a golf course or a sod farm , the rough cut will still do a very nice job. A new one is over $5000 but make no mistake, a Ford or JD flail is no comparison to a Mott/Alamo. Just compare the thickness of the deck for starters. The ring mount Mott knives swing in all directions, don't plug up, are reversible and use less power than other types of knifes. You must run 540 RPM on the PTO or the knives will stretch. It is a weird phenomenon that was discovered when some users were trying to run them at a lower RPM (to save fuel) or on too small a tractor. They are not made for cutting brush but will cut 5' tall grass and weeds without a problem if you have the H.P. Yes, it's worth buying but remember $1800 is the asking price, not the selling price. $1500 wouldn't be a bad price if all the knifes looked fairly good and it worked properly without vibration. Check out the Alamo web site. That's the same mower they use on the back of an Interstator. They haven't changed much in 40+ years because they were such a superior design to begin with. 40 PTO H.P. would probably run an 88" in 6" grass but you'd might have to take a narrower swath if it was really thick or wet. 40 engine H.P. would be a little low for an 88" unless you were cutting grass on a regular basis. A commercial mowing contractor up here used to use 74" Mott's behind MF 245's with 42 PTO H.P and they pretty much cut anything they encountered. Parts shouldn't be a problem at all. They list some parts manuals on the Alamo site too.
