I used my heater a few times, but in sunny weather, the sunlight heats you up pretty good even in 30 degree temps. I love that cab, but it is a lot more difficult with a cab to work the FEL and gauge distances and sometimes the glare on the glass is downright impossible to see. That said, I still wouldnt trade for one without a cab. Sometimes, for really finess stuff up against buildings etc, I will fire up the little Yanmar. I really would love to trade my 50 HP Yanmar for a little SCUT Kubota with TLB. That would be perfect companion for the LS.
