I got the mower from my father-in-law. Everything worked well on it for the most part.
It had about 200 hours on the meter when the Peerless 2000 transmission started to bog down. There is a YouTube video showing a backdoor method to service the transmission, but the guy is long winded and uses some foul talk. However, it's worth viewing to restore the transmission back to great condition.
Around the 300 hour mark, the single cylinder Briggs & Stratton 18.5 horsepower engine just blew up.
Rather than pay a few thousand for a new mower, I found a Kohler 18 horsepower (M18) V-Twin to swap easily. This mower behaves better than my neighbor's GT5000 in tackling any tall grass. I really mean tall, like over 18 inches!
By the way, the deck adjustment arm broke shortly after getting the mower. I just use the deck wheels to adjust the height.
