Rated 5 out of 5 by from Great Lawnmower From the first time I got on this lawnmower it was the best experience I've ever had mowing my lawn. I have about 2 acres and did it in about half the time it took on my old tractor type mower. The handling ease is wonderful and even mowing grass close to a foot tall no bogging down. The other thing is this mower makes it fun to mow the grass. I haven't had it long but the quality and durability is fantastic to this point. I would highly recommend this mower to anyone who wants the best!

Rated 4 out of 5 by from mustang 42 XT Over all the machine appears to be well made, handles well, does a good job of cutting. There was an issue which I resolved. I started having a problem getting it to start without running the battery down. Investigation showed that the fuel filter and line had drooped down so that there was an air pocket above the fuel in the filter which prevented starting. I tied up the fuel line so the filter was horizontal and that fixed the problem. The one thing that stops me giving a top rating is the fact that you cannot keep the mower going when in reverse. This makes mowing around bushes difficult when you have to go back and forth several times.

Rated 5 out of 5 by from Beast of a mower best I ever owned! I have owned my Troy-Bilt for three years now and love it! I have change the blades once and it was not that hard to do.It takes me about have the time it used to on the tractor type mower. It takes me longer to do the weed eating part of my 3/4 of an acre then it takes to cut the rest of the yard. This is the first Zero turn I have had and would buy another one if I ever have to. But the way this mower runs it should last forever. Best running mower on the market in my opinion!

Rated 5 out of 5 by from THE BEST!! Enjoy your ride! Buying same one again, lost ours in our house fire. We loved ours, my husband is 75 and this mower is so easy to turn, operate and does a beautiful job. No problems at all. Best mower we have ever purchased, so in process of buying another, we have 1 acre at new house and can't live without another. I would most definitely suggest buying this if you want to enjoy doing your yard work with ease and no worries about problems!

Rated 5 out of 5 by from Greaaate Machine Back in the 70's I purchased a 6HP (Horse) Troy-Bilt Tiller and it still runs. The rope for starting the engine has broke but will get it fixed. It's right at 45 years of age. An excellent Machine. Have a question - my Mustang 42, the zero-turn machine I purchased last year from Lowe's, came with an Operator's manual. I read front to back several times, but can find no place about type of oil to purchase (10-30, 5-20 etc) nor how much the engine carries. My eyesight may have failed me, being 4 score plus 3. My grandson has a different type mower at his house and once he used this machine, he now finds fault every week why his won't run and needs mine badly. He gets it of course but this is the first mower I've ever own that I enjoy just getting on and mowing . Really pleasant to mow with. I do have a John Deere, plus a Kioti tractor for the field, but I push the JD to the wife. Any help on my question about the oil will be appreciated. Thanks and regards to all. Cbuck

Rated 4 out of 5 by from Most Excellent mower We are very happy with the Mustang 42" mower. In particular, the wife can easily use it. We followed the instructions with 30 minutes of now mowing to get used to driving it. Far exceeded our expectations. The changing of blades and deck removal couldn’t be easier. Wish the instructions had more picture or if there was a YouTube on it because all the YouTube videos we watched made us thing it would be a big project and it was almost too easy. Only criticism I have is the mulching system outlet cover didn’t seem to fit right and we had a little problem figuring it out. We alternate between mulching and bagging and wish there were better instructions on switching between them.

Rated 5 out of 5 by from Great product thus far The only thing I would add is a sun shade and a easier seat adjustment.

Rated 3 out of 5 by from Most is okay, but nothing is great. I have now owned this about a year and a half. I have been frustrated with a few things: The extra mulch kit that I ordered with the lawnmower doesn't fit right. Grass blows out of areas that I had to duck tape (embarrasing). The blades don't cut all the grass. After I mow I look around and find blades that peek out that never were cut. The reverse safety feature of cutting off your engine is obnoxious. Why have a zero turning mower if you can't have freedom to move around? Last, the mechanism to move right doesn't perform well. Most of the time it lags and I don't know how to fix it.
