I have serviced several Yazoo mowers most were custom built nursery mowers but one is a ZTR ZKH61253 which was actually built by Husqvarna but it now longer has parts available.

I have the YR60 (60in deck) 1980 model, bought it in 1990 and still going today. (actually just change the axle seals #1902-012 this week first time since i owned it)
Amazing how a 20Hp engine could manage to run a 72" deck quite fine but now days you seem to need 20 Hp to run a 42" deck
So either those old horses were a lot stronger or modern grass has become a lot tougher .
FWIW just finished servicing one of those MTD RER's running a 30" deck from a 190cc 7Hp engine and it did a fine job on the 3 acres of 2' tall seed heads but struggled a bit with the tussock grass . SO I had to run back over a few spots with my powerful 8-24

Many lawn mowers have more horsepower than the original VW bug.
