New Holland’s new T8 SmartTrax Series brings rubber track traction and wheeled tractor versatility. Although based on the established T8 Series, SmartTrax tractors have important design differences. These include purpose-developed high torque axles that match large-diameter front wheels with the rear tracks. This enables full power to be delivered between the front wheels and rear tracks for optimum performance.
"SmartTrax T8 Series tractors have been developed to deliver the proven versatility of a wheeled tractor with the enhanced traction and flotation of rubber tracks," says Dan Valen, New Holland cash crop marketing segment leader. "The rubber tracks are matched to large diameter front wheels to deliver excellent maneuverability and to overcome some of the issues that may arise with conventional twin tracked vehicles. A key feature of SmartTrax is the ability to turn tightly and cleanly at the headland. This improves versatility as the tractor is also suitable for top work, such as spraying and top dressing."
Designed for high power applications, SmartTrax is offered on the top three models in the T8 Tier 4B Series: T8. 380, T8.410 and T8.435, offering a rated horsepower of 311 hp, 340hp and 379 hp, respectfully.
A T8 SmartTrax has a larger contact patch with the soil to enhance traction and reduce ground pressure and compaction. The contact patch of the 24" SmartTrax system is up to 65% greater than a 710/75R42 single rear tire set. The 18" SmartTrax system is 35% larger than a set of 480/95R50 rear duals. The reduced ground pressure allows earlier access to drying land and can extend field work in the season with a reduced risk of damage to the structure of the soil.
T8 SmartTrax tractors benefit from wheeled tractor agility. Topsoil disturbance in a tight headland turn is minimized, with the rear tracks following the path of the front tires without forming a "berm" ridge. The combination of wheeled front axle and rear tracks enables a New Holland T8 SmartTrax tractor to operate at full power in turns around wet field areas or on the headlands. This full power capability is a key advantage over twin tracks, which loses power at this critical time when full power can get you through the tough working conditions.
Purpose-developed axles have the high strength build required to transfer high power and torque to the ground as well as carry heavy loads. The front axle is designed to transfer full power to large diameter wheels while still allowing a 55º turn angle. This ensures a T8 SmartTrax can turn tightly for optimum productivity.
Seven different working widths.
By offering a choice of undercarriage, New Holland T8 SmartTrax tractors can be specified to offer a choice of working widths, with track spacing choices of between 76" and 152". The actual track width can also be matched to suit specific needs: "conventional" narrow undercarriage models have a choice of 16", 18" or 24" tracks. For use in more extreme conditions, including steep terrain or extremely wet conditions, wide undercarriage models are available in 24" or 30" tracks.
Farmers still have a choice of Auto Command continuously variable transmission (CVT) or Power Command full powershift transmission on the T8.435. Both the T8.380 and T8.410 come standard with full powershift Power Command.
The addtion of SmartTrax increases the overall height of the tractor, so New Holland designed new access steps to make getting in out of the cab safe and easier. To accommodate the revised steps, the fuel tank is re-profiled but fuel capacity remains the same—178 gal.—as the wheeled tractors. AdBlue DEF capacity of 99 gal. is also the same.
