The New Cub Cadet 42 in. 22 HP Kohler V-Twin OHV Zero-Turn Riding Mower features a steering wheel instead of lap bars, so it’s easier to learn and use. The 42 in. cutting width helps mow large areas of grass to reduce mowing time and the heavy-duty double-blade cutting deck is rust resistant for long-lasting use. The zero-turning radius offers efficiency and control when mowing and the automatic transmission lets you set your own pace. Even while mowing at different speeds, the dual hydrostatic transmission provides true zero-turn performance all while protecting your lawn and providing unparalleled stability. For added comfort, the simplicity of gas and brake pedals matches the arrangement of a car’s control and movement. To go forward, press the gas pedal. And to go in reverse, simply push the reverse pedal that sits right next to the gas. And with Synchro Steer Technology, the steering wheel controls both the front wheels and the independently controlled back wheels for greater maneuverability, tracking and stability on tough terrain and steep hills.

Rated 4.6 out of 5 by 12 reviewers.
Rated 4.0 out of 5.0 by somewhat dissappointed This review is comparing to a lap bar zero turn. This mower is not a true zero turn. It will not get as close to tight objects as a lap bar. You must go a couple feet past end of mower to do the "zero" turn, or you will have an uncut area. If you go to a unmowed area, turn on blades, and "zero turn", there is a 16-18 inch uncut area! Otherwise, this mower has an excellent cut with good scattering of clippings. It mows hills great. However, I have more trimming and weed eating to do compared to old mower. Might do just as well to save $1200 and get a tight turn lawn tractor. Also a big gas hog. May 10, 2015
Rated 5.0 out of 5.0 by Waited - Studied - Purchased - Very Satisfied Took over a year to finally buy the RTZ. I researched the web, read other reviews, went to the big box (HD) store and independent dealers and asked questions. The independent dealer I purchased from let me ride around on the mower -- something I couldn't do at HD. I had the mulch kit installed. Haven't had a problem with the blades stopping when going in reverse -- got used to it. Fun to mow with this machine. I used to borrow my neighbor's lawn tractor and find the RZT has much better traction and much more control on hills. It is loud because the engine is not covered and is right behind the seat so I use ear protection headphones and listen to music while I mow. I have about 20 hours on my RZT now and it runs perfectly. I'd buy it again and recommend it. November 16, 2014
Rated 1.0 out of 5.0 by Piece of junk I have the 42" ZRT-S. It has the two blade system. There is about 1/2-3/4 " space between the two blades. Well you can imagine what this does. Yep, it leaves a neat little strip of uncut grass hanging around right in the middle of your cut. This requires you, yes you to double your passes. Might as well just by a 21" mower because that's exact! yep what it is. August 30, 2014
Rated 5.0 out of 5.0 by Great machine Great cut, fantastic control, great power, does not clump. Love my ZTRS. Now had it for 2 years. It's a winner. August 30, 2014
Rated 5.0 out of 5.0 by very impressed I have a residential yard with some pretty steep hills that I used to cut with a gt2542 that was a great tractor but always felt top heavy and at least half the time I was nervous. I sold it for half what I paid 8 years later which is impressive and says a lot for cubs. I decided that the rzt s that says for hilly terrain had to be safer with the lower center of gravity? Boy was I right it is so impressive I can turn around in the middle of the hill and go back up without any fear. The 22 hp motor is crazy powerful. I wrote this to give back to the cub engineers for giving me peace of mind. If your wanting something for residential hills I doubt you could do better thanks cub cadet I for one am a very happy customer! August 30, 2013
Rated 5.0 out of 5.0 by Saves time and makes the yardwork enjoyable This is really a great product. Just bought mine in May '12 and can't believe the time it saves me. I look forward to cutting grass. It's great on Westen Pennsylvania hills, provides a clean cut with nice lines and runs like a champ. My yard looks spectacular after a fresh cut. The steering wheel on a zero turn is brilliant. I've never thought I could own a riding lawn mower with so much maneuverability and ease of use. I really like the deck wash system and the tractor is just really comfortable to drive. I'd recommend this product to anyone - and already have to a few neighbors. August 27, 2012
Rated 5.0 out of 5.0 by lawn boss Bought my RZTs 42 spring of 2013. I'm very satisfied with the speed and quality of the cut this mower provides. A well built machine. On top of that, it's fun to ride and I actually look forward to mowing! September 20, 2013
Rated 5.0 out of 5.0 by Finally!! Someone got it right This is what a zero turn mower has always supposed to have been. The steerable front wheels work great on hillsides and the steering wheel makes for a very intuitive experience. It just goes where you want it to without all the lapbar learning curve...and panic mistakes. Why would anyone even want a regular garden tractor or conventional zero turn? Kudo's to the entire Cub team for an excellent execution of a superb product. April 10, 2013
