Rated 5 out of 5 by from It doesn't get any better I bought the troy bilt bronco based on my experience with a troy bilt push mower I bought 15 years ago that is still running strong to this day. I have had my bronco for 1 year now and use it every ten days or so on my 3 acre lot. The bronco is easy to use and perform maintenance on (oil changes, air filter, ect.). The one of the two items I would recommend improving on is the oil drain spout on the engine, it can be slightly harder to open than I expected. The other item would be a mulching blade because this mower cuts grass on effectively that it produces a lot of clippings. Neighter of these small issues would have deterred me from buying this mower by an means and even if these were improved on the next in the future I have a feeling that I will not need a new mower for a very very long time. There are many easy to install asssesories you can and to this already excellent machine, I personally added a deck washing attachment and a bagger. For this price point on a mower I am very confident there is no better mower out there both in quality and performance. The bronco rides smooth, turns on a dime, and cuts like a champ leaving your lawn looking like a golf course. It is extremely easy to operate even for the most novice of operators, with many safety features to keep you safe such a the reverse mowing safety ( yes this beast mows in reverse) , the parking break that holds even on steeper hills, and that "dead man's" seat sensor that shuts the mower off immediately when the diver leaves the seat. I currently only have experience with the bronco and a 15 year old push mower but troy bilt products have not failed me and have proven to be very reliable and easy to work on. If you are in the market for a riding mower the bronco will not disappoint. Very satisfied with my bronco and troy bilt's products. Keep up this quality going!

Rated 4 out of 5 by from Solid tractor so far I bought this tractor about a month ago, & am very happy with it so far. Well built, runs great, does a great job of doing an even cut on the lawn, handles well, comfortable ride, the reverse mowing process is pretty easy & works great. So far, I have only found 2 small changes I would make. 1, I would have some type of hold down for the hood. I don't like that it doesn't fasten to the body. Just my taste. I would also have some way to pick up the plastic side discharge chute other than leaning way down to hold it up by hand, for when I put it in the garage or have to mow right up next to an obstacle like a flower bed or building. I will probably jury rig some type of bunge cord to the chute so I can pick & hold it up as needed. Again, just my taste. Other than those 2 nitpicky things, I am very happy with my choice.

Rated 5 out of 5 by from Cuts great I bought the Bronco 42" rider about a month ago. Happy with it so far. Installed the mulch it and it works nice. The only thing so far I wish there was an option to turn the headlights on and off while it is running.

Rated 5 out of 5 by from Tough as an old Ford pickup truck! I'm not the most careful user and my 2011 Bronco has a number of dents and dings. I keep the Kohler engine serviced though, and the lube points oiled/greased, but I don't worry much about its appearance. The engine purrs, the deck cuts smoothly, and the machine steers easily. Like I said, it's like the old '48 Ford pickup my uncle had on his farm -- looks like heck, runs like a Swiss watch.
