Plus or minus one-eighth of an inch accuracy from a machine light enough to leave no tracks or ruts.
Laser grading has always required heavy equipment: motor graders, compact track loaders, skid steers. That weight is what drives the grade tolerances those machines can hold, but it also compacts the soil, leaves ruts and tracks, and makes working in tight areas around a field difficult or impossible. The ABI Force Z-23 equipped with laser capabilities changes that equation. The Z-23SL, SLT, HL, and HLT are the world’s first stand-on zero-turn laser finish grading machines, with fully automated systems that achieve plus or minus one-eighth of an inch accuracy from a platform light enough to leave no tracks, even at near-zero-turn.
The Z-23SL, SLT, HL, and HLT are the laser-capable configurations of the ABI Force Z-23. Each is built on the same stand-on zero-turn platform but configured for a complete laser electronic system that enables fully automated finish grading. The laser system works in tandem with the mini box blade and VibraFlex mid-mount attachments to control grade precisely across the full width of the machine on every pass.
All four models deliver grade accuracy of plus or minus one-eighth of an inch, which is 0.125 inches or 3.175 millimeters. For context, that is the tolerance level required for professional-grade infield drainage and the kind of precision that eliminates the standing water and slow drainage that costs games and turnaround time. This level of accuracy was previously only achievable with equipment several times the size and cost of these machines.

Traditional laser grading equipment relies on machine weight to hold a cutting edge at grade through varying soil resistance. The heavier the machine, the more consistent that engagement can be, which is why motor graders and skid loaders have been the standard tools for precision grade work. But that weight comes with real costs on a sports field: soil compaction that kills root systems, tracks and ruts that require remediation after the machine leaves, and a footprint too large to work precisely in tight areas around dugouts, warning tracks, and field corners.
The Z-23SL, SLT, HL, and HLT address this through the RVF hydraulic mid-mount system rather than machine mass. Variable hydraulic downward pressure applied directly to the attachment holds the cutting edge at grade without requiring the machine to be heavy. The result is laser grading accuracy from a platform that travels on a standard trailer without a CDL and leaves no tracks or ruts even at near-zero-turn.
A precisely graded infield sheds rain faster than one with grade inconsistencies. Drainage that works correctly means quicker turnaround after rain events, fewer postponements, and more games played on schedule. For a professional facility running a long season, that translates directly into avoided revenue loss and avoided disruption to the schedule. For a parks and recreation department managing community fields, it means the fields stay available for the youth leagues and adult leagues that depend on them.
For field installers, the Z-23SL, SLT, HL, and HLT bring laser finish grading capability to projects that previously required bringing in heavy equipment at additional cost. The compact footprint accesses tight areas that larger machines cannot reach, and because they do not compact the soil or leave ruts, they can work directly on the finished surface material without requiring a remediation pass afterward. The mini box blade handles material distribution at grade, the VibraFlex loosens material ahead of grading passes to keep the blade fed, and the laser system controls the elevation automatically.
The Z-23SL, SLT, HL, and HLT are not just renovation tools. Leah Withrow at the Reno Aces laser grades the infield and warning track multiple times per year, sometimes five or six times depending on the event schedule. Having the machine already on property means those grade corrections happen on the facility’s own schedule rather than requiring a contracted equipment mobilization. The Gwinnett Stripers acquired the Force with the laser-ready system specifically because their multi-use facility needs grade precision maintained across baseball, soccer, and football use.
The Z-23SL, SLT, HL, and HLT are not replacements for earthmoving equipment on rough grade and bulk material work. Use larger equipment for that. These machines are built for finish grading, the final precision pass that establishes the exact grade the field will drain to. Where they outperform larger equipment is in the specific conditions that finish grading demands:
The ABI Force Z-23SL, SLT, HL, and HLT are each available with a complete laser system configuration. Explore ABI Force options and packages at ABI Attachments, or speak with a Sports Turf Specialist about laser grading setup at (877) 788-7253.
It means the finished surface will be within one-eighth of an inch of the design grade at any point across the field. For a baseball infield, that precision ensures drainage flows consistently toward the designed low points rather than pooling in micro-depressions. It is the tolerance level required to meet professional drainage standards and the level at which rain events clear the surface quickly enough to keep games on schedule.
All four are laser-capable configurations of the ABI Force Z-23, each built on the same stand-on zero-turn platform with a complete laser electronic system. To find the right model for your specific facility, field type, and application, speak with a Sports Turf Specialist at (877) 788-7253.
No. The light footprint of the Force platform and the zero-turn design allow them to work at near-zero-turn without leaving tracks or ruts in the finished surface. This is one of their most significant advantages over skid loaders and compact track loaders used for laser grading, which leave surface damage that requires remediation after the machine exits the field.
It depends on the facility and the event schedule. At the Reno Aces, head groundskeeper Leah Withrow laser grades the infield and warning track five or six times per year depending on special events. For most professional facilities, two to four times per season keeps the grade within acceptable drainage tolerance. For a facility that also hosts non-baseball events, additional passes after those events may be needed to restore the grade.
Both. For new field installations, these machines handle the precision finish grade pass on the infield mix before the surface is completed. They access tight areas that larger equipment cannot reach and do not compact or rut the finished material. For ongoing maintenance, they restore grade drift from regular use. For installers, having one of these machines on a job eliminates the need to bring in a separate laser grading machine for the finish pass.
