No plans on a cab with heater for my x738 but if they ever come out with a cab with AC I'll be first in line.I have an X734 with cab, heater and 47" blower. Amazing machine for snow. I'm 50, and I went with a used machine that already had the cab and blower. Got a decent deal on it. You might think it's overkill, but I tell ya what, we aren't getting any younger, and the x7 series machines are a lot easier to change over that the smaller series. The only thing I wish I had was the diesel engine. The gas versions tend to guzzle the petrol.
Future you will appreciate the x7 series. Besides, it kinda becomes a side hobby.
Check out Roger's x7 series with cab. He set himself up for life.
