Have a 463 w/the smaller 722E that I only use for snow removal. Perfect machine for what I use it for. I currently draw heat from the top of the radiator into the RPO behind the seat through a 4" dryer vent tube and a shroud positioned above 1/2 of the radiator. Works good but get exhaust fumes more often than I should. Was wondering how heater hoses hook up on these machines and where the factory installs the heaters in these smaller skidsteers. If anyone has a picture that would be great. Thanks a ton!
