Starting at 20F isn't a big deal. My dad's JD 730 would start with minimum issues at -20F in ND when I was growing up. It was a sad day when he traded for more power, it was an easy tractor to work with.
I’d like to but axle mounted duals are difficult to do on a 730 but it’s been done before. Clamp on duals are possible too but I’d rather not go that route
First of Mae is the best thing about coming home NOT the pork burgers I grilled especially for you??? Second, you will be doing multiplication and division worksheets this summer!
