TRANSMISSION
The Kubota STV40 features a hydrostatic transmission, providing seamless speed control and ease of operation, especially in varied terrain and task conditions. With its infinite (3-range) forward and reverse gears, it allows for smooth transitions and precise maneuverability, making it ideal for tasks requiring frequent direction changes, such as landscaping or loader work. However, users should note that hydrostatic systems may incur higher maintenance costs and reduced efficiency compared to manual transmissions under certain heavy-load scenarios.

MECHANICAL
The Kubota STV40 features a 4x4 MFWD system for enhanced traction on varied terrains, complemented by a mechanical rear differential lock for improved grip in challenging conditions. Its hydrostatic transmission allows for smooth speed control and ease of operation, making it ideal for tasks requiring precision. The option of a cab provides operator comfort and protection, though the basic two-post ROPS may limit weather and environmental shielding if operating without it.

KUBOTA STV40 TIRES
The Kubota STV40 tractor offers versatile tire configurations tailored for specific applications, including standard agricultural, lawn/turf, and industrial use. Standard ag tires provide optimal traction in field conditions, while lawn/turf tires minimize ground disturbance during mowing or maintenance. However, selecting the inappropriate tire type can lead to compromised performance and potential damage to sensitive terrains, so consider your primary use case before investing in additional tire sets.
| Standard tires (ag) | Front: 6.00-12. Rear: 9.5-22 |
| Lawn/turf front | 24x8.50-14 |
| Lawn/turf rear | 13.6-16 |
