I too have a 4100, and am very happy with both the quality of build and the performance from a 20HP tractor. I use mine for lots of things from mowing, plowing, tilling, to box blade and scraper blade use. I also do snow plowing with the scraper blade. This tractor has done everything I've asked of it, even some pretty heavy dirt moving and shaping. It works amazing for such a small tractor, just does the big jobs a little slower than the bigger machines. Now if only I could scrape up enough cash for a 410 loader. Then I could really have more fun.
