SRS™ Z1 Stand-On Mower
Ride Confidently Into Narrow Spaces with Advanced Comfort and Stability
The Soft Ride Stand-on SRS™ Z1 is raising the bar with our adjustable operator platform, featuring suspension technology, optimizing operator comfort and increasing productivity! The superior balance provides stability and manoeuvrability that exceeds expectations for traction and handling. The Soft Ride Stand-on SRS™ Z1 is designed to allow for quick operator exit and re-entry which is particularly useful if you frequently have to open gateways, pick up litter or often require loading and unloading for transporting the machine to different work sites. Its compact footprint allows the SRS™ Z1 to be transported in the back of a standard-sized van which is a significant advantage because it limits the need of a trailer. This simplifies the search for a parking spot in busy urban areas.
