I have the front blade, two-stage snowblower, and broom for my 4100. They all also work on my friend's 425 quick-tach mount for his single-stage snowblower. I would assume that the implements are all still the same on the newer tractors.
I actually bought the snowblower from a dealer who only handles garden tractors, but he was able to order the correct adapter kit for my 4100 I think the drive shaft may have been a slightly different length (different part number). There was also a difference in the length of the hydraulic hoses. The kit for the larger tractors also included some bolt-on end-plate reinforcers and drift-bars. They must figure that the larger tractor can carry the weight of the extra 1/4" of steel.
The blade works great for removing snow, buts sucks for any dirt work other than maybe backfilling a trench. Part of the problem is that the mount on my machine is fairly worn in. The slack in the adapter, angle mount, and quick-tach allows the whole works to kind of flip down and wedge the front of the tractor up. The pivot point isn't really quite low enough to maintain a nice level shaving/grading action. The sub-frame mount somebody mentioned would probably be better for dirt.
The slack also leads to an inability to generate down-pressure when pushing snow. When I really want to scrape the pavement clean, I am not always able to push down enough to lift the front tires off the ground when going over a slight hump.
Finally, I also wish the blade was a bit wider to carry more snow. Maybe 66" or 72" instead of 54". My 4100 has no problem pushing as much snow as the blade will hold. A wider blade would take fewer passes to clear a given area.
