I just purchased a L4400 with a backblade to plow my 0.8 mile uphill driveway. I have R-4 tires and have a hard time getting up the hill with a foot plus of snow. I was calling around to find some which is almost impossible this time of year and one of the service people told me not to get chains with my 4WD. He said it will destroy the front end of my tractor. On this board it seems many do put chains on and no one makes mention of this problem. Does anyone know about this?
