The Cub Cadet RZT 50 is a popular design for larger lawns up to 3 acres in size, though it isn't without flaws. Even so, we give it a Budget Buy designation for larger lawns.

The RZT 50 zero-turn riding mower is powered by a beefy 22-hp Kawasaki V-Twin overhead valve engine -- more than ample for larger residential lawns. The twin-cylinder engine is more efficient and has a little less vibration than single-cylinder engines. The engine has a full-pressure lubrication system for longer life. It gets around using a dual hydrostatic transmission with each controlling a single rear wheel.

The 50-inch mowing deck contains three belt-driven cutting blades to mow 25 percent more lawn per cut than a 40-inch mower. Combined with a forward speed of 6 mph (3 mph in reverse) and this mower can reduce mowing time dramatically over many other types of mowers. Cut grass is discharged through the side, sent through a side chute to a rear bagger (optional) or mulched (optional). There are four adjustable-gauge wheels at the deck corners to minimize scalping the lawn.

In fact, there's very little difference between this model and Cub Cadet's RZT 42 except that the RZT 50 has a heftier engine and a wider cut. The frames on both are stamped steel -- good, but not for heavy-duty use. The seat is adequate, but may get a little uncomfortable on long mowing jobs. But the prices for both are on the low end of the marketplace, especially if competitive discounts or off-season sales are available. So if you're looking for a relatively low-cost zero-turn riding mower, consider both of these models depending on how much grass you have to cut. Also consider the weight; the RZT 50 tips the scale at about 525 pounds, nearly 50 pounds heavier than the RZT 42. It's a good thing they are on wheels.

One of the problems we found with this and a few other ZTR mowers is that it's difficult to know how much fuel is left in the 3-gallon tank. The fuel is filled at the left fender and flows into a black tank located below the driver's seat. Some other models have a tank of clear plastic that you can visually check, but this one doesn't. Even our dealer couldn't find the fuel level. If you're good at estimating fuel levels, this isn't a problem. Otherwise, take a look at other models where fuel level is easier to estimate. There are lots of them out there.

The Cub Cadet RZT 50 is a value-priced zero-turn riding mower with some limitations reflected in its lower price, but it's worth a Budget Buy designation.


Pros: Strong engine, dual transmission for maneuverability, lower price than similar ZTRs
Cons: Frame not as solid as others, can't read the fuel level, not comfortable for long rides
