Original Tractor Cab (OTC) installed w/ glass windshield and electric wiper. No more freezing to death in 45mph wind driven ice. Installation took about 3hrs and was very straightforward. Put my own LED work lights on it, cheap Amazon specials. Also put some red LEDs inside so I can see the controls.
I haven't installed the little electric heater included and don't think I'll need it. The heat of the machine itself seems to keep it warm enough. And the sun definitely makes it toasty. If I was spending hours upon hours in it, I'd probably get the Curtis engine coolant supplied heater. I may need to put a little 12v fan in it for windshield defog if it's humid, we'll see.
For the winters here in MD, this $1700 cab is perfect. A $4-9k Curtis or Mauser cab would be fabulous but totally not worth the $$.
Made in USA, and actual humans from Indiana answer the phone when you call. Shipped same day and delivered 2 days later. Very pleased. Of course now it probably won't snow the rest of the year.
