The Troy-Bilt TB230 self-propelled mower features a reliable starting 159cc Troy-Bilt OHV engine with Check, Don't Change system that eliminates oil changes. By simply checking the oil each time and topping off as needed, this system reduces maintenance time and having to dispose of old oil. True variable speed front wheel drive transmission will turn more easily around landscape features and obstacles. Equipped with the TriAction cutting system, this system includes a rake bumper to lift grass upright, a specially designed blade for a finer mulch and a symmetrical deck for superior grass flow, eliminating clumping. The TB230 self propelled mower comes with three options to dispose of grass clippings, including side discharge, mulch or rear bagging capabilities. Equipped with 11 in. rear wheels for improved traction and maneuverability on hills and uneven terrain, plus dual lever height adjusters for easy change of cutting height, you can depend on a Troy-Bilt mower to be rugged and reliable. Your work in the yard inspires us to design, test and build the most reliable mowers we possibly can.

Better than expected!
I ordered this lawnmower in July 2019 to replace another Troy-Bilt mower i purchased in 2003. The old one still works pretty good, but decided to give to my Niece. This new Troy-Bilt TB230 operates with ease and cuts the lawn in less time because I no longer need to cut it twice for the grass to look perfect. The self propelled lever makes it easy to control the speed of the mower for all.

Good Mower
I have used this mower 7 times it starts on no more than two pulls, has a nice even cut even on rough areas. It is a little heaver than my last mower but that has not been a problem. I will add at this point I am 80 years old and a lot of things are heaver than they used to be. Good product

I bought this mower on line. I have only used it twice but I love it. great cut, very easy to use. starts on first pull.
I would have given it 5 stars but the rubber on the handle grip has already started to come apart. It is rough and rubbed a blister on my hand. I can wrap the handle so no big deal but it should really bee looked into
