Best Mower for the Money
I retired my old craftsman mower, and went shopping for my replacement. After looking thru the specs, reading quite a few reviews, I went to look over the list of three contenders in my price range. I went to each store, looked the mowers over, tried sitting on them, ease of reaching controls, and for smooth operation of levers and peddles.
I chose the 42' Bronco mower, and I'm glad I did! It has more horsepower then the other two contenders, cut a level lawn on a hilly piece of land, and my back didn't hurt when I was done!
The higher back seat was really nice!
The mower has a mow in reverse feature that many do not have, but as it states. Be very careful that no children or animals are near you when using this feature.
Oil changes are simple, and a piece of drain hose is supplied in the owners packet. Just slip one end over the drain plus and put a container under the other end. no big messes to clean up with this rider!
The 18' turn radius is also nice for a mower of this size, you can just get in real tight to shrubs, trees, and other plants.
Am very happy with this rider, and am considering one of Troy Bilt's 4 cycle grass trimmers as my next purchase. Would highly recommend this rider to anyone looking for the best bang for the buck!

Mulch Kit WARNING, 2015 Bronco manual is WRONG #
The mulch kit that is listed in the manual for the 2015 Bronco is the WRONG one. The one listed in the manual is for models that were made from 2010-2014. It absolutely will not fit the 2015. You need the mulch plug that is dated "2012-"

Every time we use this mower, something it breaks. 2nd time we used it the motor disenegrated. Warranty covered that but now it is out of warrantyand the motor disenegrated again. Probably less than 24 running hours on it. In the shop more than out and constantly breaking ball joints and steering gears, which I was buying in bulk. I won't get it fixed this time and will buy a better made product. Never again.

Need parts (mulch kit)
I bought this mower yesterday and also purchased the mulch kit. I put the blades on with no problem, but the part that replaces the Shute does not fit. I took it back to Lowes and they said that there was no kit for this mower ( bronco 2015). What am I to do???????????

Information
Unfortunately troy bilt does not manufacture these units with the option of cutting in revers anymore. Due to safety reasons. Only if you are very very mechanically inclined, I also would not recommend trying to "rig" the unit to cut in reverse. May void your warranty

Bronco Lawn Tractor
Very nice tractor. I like the way it handles. I do wish it cut the grass in reverse. Starts easy, handles easy. Less vibration would have been nice.
Overall a nice mower. i would recommend to my friends.

Best Mower I have ever owned.
I purchased my Bronco in 2010. Worked great until 2013. The engine blew up. Troy-Bilt connected me to the Kohler folks and they stood behind the engine. I have my mower back and just finished the last mowing of the season. I would highly recommend this mower. It was a good price and takes care of my 2-plus acres without any problems.

Riding mower, Bronco
I have two issues. First issue I have is the mulching kit. The plate blocking the discharge shoot allows grass to build up between the frame and plate. The second one is the battery. It is just able to turn over the motor to start it.
The biggest plus to me if the 19 HP Kohler engine. There is power to spare which is a huge improvement over the mowers with the smaller engines. When I hit heavy grass there just isn’t any change in speed or cutting power. I would strongly recommend getting this larger engine. The other big plus is how easy and sharp it turns. This has reduced the amount of trimming I need to do and the time it takes to cut the lawn. A great little mower.
