I am thinking about chains for the front of my
L3200 also. The rear blade can really "rudder" the tractor when moving heavy snow with a slippery base. The tractor doesn't run out of traction so much as it runs out of steering capability. So I think chains on the front would be a great improvement.
I think the only hassle for me is that I'd need to remove them before clearing snow on the concrete apron by my house, and at the street, and before driving into the barn. So it might take some planning -- use them for the initial passes to clear the drive and then take off.
