I know that its 100 degrees out with heat indexes in the 110 range, but I was wondering how important is an engine block heater for a Mahindra 6500. Im in the midwest and we do get cold in the winter. Don't know how much work I will be doing when its that cold, but would not want to have trouble starting when its 20 degrees out. Although after being outside most of today, 20 degrees in a duck blind or on a deer stand sounds a whole lot better!!!!
