I'm pretty sure most commercial mowers will cut just about anything if you slow down.I have cut my 10 acre field with all 3 of my machines without any trouble,just slow down a little and listen to the engine. I always make sure to clear the deck after in the event it's wet and clogged.My mowers are 05 Dixie chopper 50 hp 72" turbo diesel XXWD5000,and a 2001 dixie chopper 25 hp kohler command xw2500..also cut with my ventrac 4231G 72", no problems with any of them...
