Below you will find an in-depth overview of the machine’s design, typical specifications, applications and operational considerations.
Design and Powertrain
The heart of the T8.350 is a high-output, six-cylinder diesel engine tuned to deliver roughly the performance expected from a 350-class tractor. New Holland equips the T8 series with engines that meet current emissions standards (Stage V in many markets) by using aftertreatment systems that commonly include selective catalytic reduction (SCR) and particulate filtration. The overall result is an engine package focused on combining high torque at low revs with compliance to modern environmental rules.
Key mechanical and drivetrain attributes that define the platform include:
- Engine: robust six-cylinder diesel, designed for strong low-end torque and extended service intervals. Depending on configuration and market, rated power is in the 330–380 hp class, with the model designation T8.350 indicating the approximate nominal output in horsepower.
- Transmission: New Holland’s acclaimed Auto Command continuously variable transmission (CVT) is available for smooth, stepless speed control and optimized fuel economy under load. The CVT is especially useful for precision tasks and when matching tractor speed to implement needs without constant gear shifts.
- Drivetrain options: configurations include two- and four-wheel drive setups, as well as factory-fitted tracks or duals. The SmartTrax (tracked) option provides improved flotation, lower soil compaction and better traction in soft conditions.
- Hydraulics and PTO: heavy-duty hydraulic systems support large implements, with high flow rates (typical delivery in this class can be in the 150–250 L/min range depending on the pump setup) and multiple remote valves. PTO outputs match the engine capability and are designed for mounted and trailed equipment typical of large farms.
Typical Specifications and Performance Indicators
Exact specifications vary by market, optional equipment and year of manufacture, but the T8.350 typically sits within the following ranges and characteristics. Where precise figures can differ by configuration, note ranges rather than single fixed numbers:

- Maximum torque: substantial torque output at low rpm to ensure pulling power for deep tillage and heavy loads; torque rise characteristics prioritize traction and hitch capacity.
- Transmission: Auto Command CVT with infinite ratios within the working range; top road speed usually 40 km/h (many markets offer 50 km/h gearing options).
- Hydraulic flow: high-flow variable displacement pump options are common; typical factory choices often range from about 150 to 250 L/min depending on specification.
- Rear linkage capacity: capable of lifting large implements; typical lift capacities for this class can be in the 8,000–12,000 kg range at the hitch, depending on specification and country calibration.
- Fuel tank: large tank capacities to minimize downtime on big farms—typical capacities in this class range from roughly 500 to 800 liters depending on fitment and market options.
- Weight: gross vehicle weight and operating weight vary; ballpark operating mass for a fully equipped T8.350 is often in the 10–14 tonne range depending on tyres/tracks and ballast.
- Axles and tyres/tracks: heavy-duty axles to handle high drawbar loads, with multiple tyre options including narrow, wide, flotation and dual wheels; track options for reduced compaction.
These figures place the T8.350 firmly in the large-tractor category, catering to operators who need both high field productivity and road transport capability for long distances between sites.
Applications: Where the T8.350 Excels
The T8.350 is engineered for large-scale, intensive agricultural operations and contractors who require a single machine capable of performing a wide variety of demanding tasks. Notable application areas include:

- Advanced guidance and autopilot systems compatible with GNSS for precision farming, enabling headland management, section control and variable-rate application when integrated with implement electronics.
- Telematics solutions such as PLM Connect (or similar) which allow remote monitoring of machine status, fuel consumption, location and basic diagnostics—helpful for fleet management and preventative maintenance planning.
- Automated functions such as programmable work modes, economy settings and sweet-spot engine mapping to balance fuel economy and performance automatically.
These systems reduce operator workload and improve consistency of work, which in turn increases effective daily outputs.
Fuel Efficiency, Emissions and Economics
Large tractors like the T8.350 are designed with fuel economy and emissions regulation compliance in mind. New Holland’s approach typically combines engine calibration for low-RPM torque, aftertreatment systems and transmission logic that helps keep the engine in the most efficient operating window.
- Fuel economy: actual fuel consumption depends strongly on the task, loading, soil conditions and operator choices. In general, CVT transmissions and engine “sweet-spot” tuning can reduce fuel burn compared with older multi-range transmissions by matching engine speed more closely to load.
- Emissions: equipment for many markets meets Stage V/ Tier 4 Final emissions standards using SCR, DPF and related technologies to minimize NOx and particulate emissions while preserving fuel efficiency and power delivery.
- Total cost of ownership: factors include purchase price, fuel consumption, maintenance intervals, resale values and uptime. New Holland aims to provide competitive service intervals and dealer support to lower operating costs across the machine’s lifecycle.
Maintenance, Reliability and Serviceability
Maintenance considerations are critical for machines working long hours in difficult conditions. The T8.350 platform emphasizes accessibility for routine servicing and long component life. Typical maintenance and reliability features include:
