The Cub Cadet iSeries ZTT 46 is an innovative entry in the world of zero-turn tractors. In this machine, the company combines the advanced hydrostatic twin transmission system that is used in zero-turn mowers with the design of a traditional riding tractor. The result is a hybrid machine that maneuvers at tight angles, yet still has the versatility and familiar steering of a tractor. It also provides the attachment capability of a traditional tractor.

Purists will note that the closer wheelbase does not offer a true zero-degree turn, but it comes pretty darn close; in fact, it is an interesting sensation to spin in place (more or less) by merely turning the steering wheel. Cub Cadet promotes the ZTT 46's balance and smooth maneuverability on hills, and we find this to be one of its winning features. Tight, clean turning ensures a nice, even cut, and the 20-hp Kohler Courage Twin-cylinder overhead valve engine pushes the mower's top speed to a modest 6.0 mph, which is a little too pokey for commercial use but is fine for most homeowners. The standard steering system is very easy to use; this eliminates the learning curve often associated with the control levers found on other zero-turn mowers. The 46-inch cutting deck is adjustable to heights of 1.5 to 3.75 inches, which again points to the fact that this mower is ideally used on well-maintained lawns with low-growing grass and weeds.

As with most ideas that seem to be too good to be true, the ZTT 46 does have some shortcomings that must be noted. While the trademark transmission and steering is exceptional, we find that the cutting deck is occasionally prone to gauging grass on 90-degree turns and on slight inclines. Also, this mower is a bit light (550 pounds), so the cutting deck jars when turning at higher speeds; this makes rugged yards and steep inclines more challenging than they probably should be. When used in mild residential conditions, the ZTT 46 will do just fine, but working even moderately rough terrain can result in a rough ride; in fact, the iSeries line is known to have mechanical issues when pressed outside the realm of light duty.

We have no problem with the ZTT 46 being geared towards residential use, though the versatility it offers has to be taken with a grain of salt. The variety of attachments available for this mower is wider than that of than any other zero-turn machine. Most of these attachments -- including two different carts, a spreader, a 25-gallon sprayer/tank, a bagger, a mulch kit and an aerator -- make perfect sense and work nicely with the ZTT 46. Given the machine's performance when tested in mildly rough summer conditions, however, the available snow thrower, dozer blade and lawn roller attachments are likely to put a good deal of strain on the tractor. Again, the key to harnessing the versatility of the ZTT 46 is confining it to light-duty jobs.

The Cub Cadet iSeries ZTT 46 is a nice, versatile machine that will perform well as long as you don't expect more out of it than light-duty jobs.
