i have the Warn plow system,and am very pleased with it too
mounting hardware was a bear (no pun intended,but just on the two brackets that mount underneath,because one bolt on either side was too close to the underside of the footrest,you can only get a quarter turn at a time on it
the brackets tuck up under enough that it doesnt interfear with ground clearance at all
and it has two pins,to pop in,or pop out underneath for the push tube,to the brackets,,,takes about 5 minutes,and im plowing
as for chains,i pushed snow all last winter with just stock tires,with zero problems
