We are looking at picking up a couple new Turf Tigers. In the past we have been running the 29 Kawaski DFI. I've been looking at the Kohler 31 EFI model. Does anyone have any experience with these on the Scag mowers? Dealer says they're $500 less than the 29 Kawaski - and they're 2 hp higher - so I've thought about giving them a go..... Thanks.
