ZTR (zero turning radius) mowers, like all lawnmowers, operate in a dirty environment. Proper and regular maintenance is needed to keep your mower operating at top efficiency and minimize costly repairs and downtime.

ZTR stands for "Zero Turning Radius." ZTR mowers have separate hydraulic pumps driving the left and right tires, and each side is controlled separately. One tire can be turning forward while the other is turning in reverse, thus the mower can pivot around its own center. This feature allows amazing versatility in trimming while mowing.

Zero-turning-radius (ZTR) mowers are popular among professionals and homeowners with larger lawns. ZTR manufacturers offer many new and/or optional features on their mowers that further increase their versatility and ease of use.

Some ZTR mowers are designed with a serious fire safety hazard. These models should be avoided.

Commercial-size riding mowers, including the popular ZTR (zero turning radius) mowers, are covered by a safety standard promulgated by the American National Standards Institute (ANSI). Even though many of these mowers are used by homeowners, those that are designed primarily for commercial use are considered commercial machines and they fall under a commercial mower standard.

A relatively new class of products in the commercial grounds maintenance industry is the self-propelled spreader and/or sprayer. This kind of equipment can potentially reduce the effort required to apply fertilizer or pesticides to lawns, but it comes at a substantial cost and will require some trade-offs in operating mode.

ZTR mowers have taken over the commercial riding mower market. In the past, there were few low-cost models available to homeowners, but this has changed. Low-cost homeowner models are now available from several companies.
