It's getting to be that time of year where I need to get a blower for my BX2380. I have a fair amount to blow but I have done most of it with a 27" walk behind and 4 wheeler with a plow so even the 50" will be a major upgrade. I can get the 50" for $3,500 vs over 5K for the 55". It's my understanding that the 55" is standard for hyd. rotation and I would have to add more cost to the 50" so it might not be quite such a difference. I really don't need the hyd. rotation because to me it isn't that big of a deal. I live in central MN so we can go years with barely any snow and maybe 1/5 we can get some decent snow, our yard doesn't have much of a problem with hard drifts so I usually don't work it that hard, in fact with the 27" walk behind that is far from commercial grade I usually use the 4 wheeler to make a windrow to make it quicker to blow.
