With over 85 years of expertise in crawler tractor design, the TK4 Series continues to deliver trusted performance in demanding terrain. The latest models feature Stage V compliant engines, offering improved fuel efficiency, lower emissions, and reliable power. Farmers and contractors can count on exceptional stability, operator comfort, and productivity—whether navigating steep slopes or working in specialized crop environments. The TK4 Series is a testament to New Holland’s ongoing commitment to innovation and sustainability in the crawler segment.
The TK4 Series crawler tractors are built with you in mind. The updated platform features a spacious layout, ergonomic controls, and enhanced visibility to make long days in the field more comfortable and productive. Whether you're working on steep slopes or in specialty crops, a TK4 delivers a smooth experience that helps you stay focused and efficient.
TK4 crawler tractors are built to perform where wheeled tractors fall short. Their track system delivers outstanding traction, stability, and flotation—ideal for steep slopes, soft soils, and specialty crop operations. For even greater versatility, the TK4.80F and TK4.100M models feature SmartTrax™ rubber tracks, offering a smoother ride, reduced ground disturbance, and easier maintenance compared to traditional steel tracks. Whether you're navigating orchards, vineyards, or rugged terrain, TK4 tracks help you stay productive and in control.
The TK4 Series is powered by advanced FPT Industrial engines that meet Stage V emissions standards, delivering cleaner performance without compromising power. Thanks to HI-eSCR 2 technology, the after-treatment system is fully integrated under the hood—preserving visibility and safety while remaining maintenance-free. Hot components are safely isolated to protect both the operator and surrounding environment.
The TK4.80V and TK4.80F do not require Diesel Exhaust fluid, making operation simpler and more cost-effective. Whether you're working in orchards, vineyards, or on steep terrain, these engines offer the reliable power and fuel efficiency you need to get the job done.
TK4 crawler tractors offer two transmissions designed for smooth operation and precise control in challenging conditions. The standard 8x8 transmission, featuring carefully selected forward and reverse gears that help maintain consistent traction and performance across varied terrain. For tasks that demand ultra-low speeds—like working in vineyards or orchards—the 16x8 transmission with creeper is available, giving you the flexibility to operate with precision and care. Whether you're climbing slopes or navigating tight rows, TK4 transmissions deliver the dependable control you need to stay productive.
You get more flow to handle more demanding implements with two hydraulic gear pumps in two separate open-center hydraulic circuits. A high-volume 11.9 gpm (45 Lpm)* implement pump delivers dedicated flow to the three-point lift and remote valve circuits, while a separate 5.8 gpm (22 Lpm)* steering and services pump allows you to maneuver with precision and ease without robbing flow from other hydraulic functions.
*The TK4.80V and TK4.80F offers a 9.4 gpm (35.5 Lpm) implement pump and a 5.4 gpm (20.4 Lpm) steering pump.
