TRANSMISSION
The Kubota STW40 features a hydrostatic transmission that provides seamless speed control, enhancing maneuverability in tight spaces and varying terrain. Its infinite (3-range) forward and reverse gears allow for precise adjustments in speed and torque, making it advantageous for tasks requiring fine control, such as landscaping or cropping. However, users should be aware that hydrostatic systems can incur higher maintenance costs compared to traditional gear systems.

KUBOTA STW40 TIRES
The Kubota STW40 features standard agricultural tires (6.00-12 front, 9.5-22 rear) that provide excellent traction and stability for fieldwork, but may compromise maneuverability in tight spaces. Alternatively, the turf tire configuration (24x8.50-14 front, 13.6-16 rear) offers a gentler footprint, making it suitable for lawn care and landscaping, reducing soil compaction but providing limited effectiveness on uneven terrain. Evaluate your operational needs—agricultural use favors the standard tires, while landscaping demands the turf tires for optimal performance.
