Riding lawn mowers

Do tell us the details about the engine in that sucker!
US built Lastec 4520 x 10' cut zero turn with 5 articulating anti scalpe decks. You can drive it over a mound like 5 guys pushing 25" lawnmowers. Cuts 10 acres/hour at 9mph... which will be nice as it currently takes me about 6 to 7. 45hp x 4 cylinder Kubota diesel. Weighs 2700lbs. The one I'm hopefully getting is 3 years old with 900 hours on it and meticulously maintained by my Wife's cousin. He owns a golf course and is negotiating a lease buy out for me to get it "cheap". New was $65k... getting it hopefully for 22. They sell at auction for over 30k with a lot more hours on them. If we can't do the deal with Lastec... it'll be goats!
