Bought a TCII, 61" deck, Kohler 29hp engine last April (2017). Mowed about 5 acres weekly on varying terrain. Had a bum fuel pump replaced. Otherwise, the mower's been an absolute beast. I'm looking forward to this year's mowing season if I can wrestle the mower from my boy. It's the only chore he actually likes. Can't compare the Kohler to a Kawi; never had one. I'm sure they're fine. I've only used B&S and Kohler (just sort of happened that way) and have never had a problem with any of them.
