Re: cold in the cab?
The cab heater is great. I 've moved snow all winter for the last 7 years with an L4610HSTC; for 10 years before that I froze on an open
L2550 .. .
We get our share of deep cold (-10 to -20 F or colder) here in Vermont and plenty of snow . .. I've never been cold in the Kubota cab--it's comfortable without a coat. In windy and blowing subzero conditions, if snow's blowing back all over the cab, the side and back quarter glass frost a bit (the rear has an electric defroster) but not so much as to reduce visibility--the defrosters generally take care of it. For what it's worth the air conditioning also holds up under pretty extreme conditions--I've done field work for hours on 90+degree days and was very comfortable. . .
And for anyone who still wonders whether their cab was worth the $$$$$$$, I suggest you try spreading manure on a windy day . . .you'll never question your decision again.
