| Production | 1991–present |
The JCB Fastrac is a high-speed agricultural tractor series manufactured by JCB Landpower, part of the JCB group.
Production began in 1991, with continual development to the present day. Generally the maximum speed of most models is 65 km/h (40 mph), but slower (40 km/h) and faster (80 km/h) versions are produced.
Design
[edit]Engine
[edit]All models have six-cylinder diesel engines. Initially supplied by Perkins Engines then Cummins, the current supplier is AGCO Power and FPT.
Gearbox
[edit]Three different gearboxes have been fitted to the Fastrac in production.
- The first type has evolved over several years.
- On introduction of the Fastrac this style of gearbox had 18 forward gears (6×3) and 6 reverse (6×1). These were organised as 6 manual gears in each of 3 ranges (Low, Medium and High). The range box also selected reverse giving 6 reverse gears with speeds similar to medium in forwards. All gear changes were made with the use of a dry clutch.
- This gearbox then had a 2-speed powershift section added after the dry clutch and before the 6-speed gearbox. This resulted in 36 forward gears (2×6×3) and 12 reverse (2×6×1).
- Following this the 2-speed powershift section was changed to 3-speed version. Giving 54 forward gears (3×6×3) and 18 reverse gears (3×6×1)
- The latest version of this gearbox a wet clutch replaced the dry clutch still with 54 forward and 18 reverse gears.
- The second type fitted to 4000, 6000, 8000 Fastrac models features a CVT (IVT) hydrostatic power-split gearbox which is one of the most advanced tractor gearboxes available.[1]
- The third type developed most recently and fitted to 7000 Series and 3000 Xtra machines has a wet main clutch, a six-speed powershift section and a four-speed range box. As reverse is at the front of the powershift section the reverse gears are spread throughout the speed range. This arrangement gives 24 forward gears (2×3×4) and 12 reverse gears (1×3×4). Note that the top three reverse gears are not available for use.
Four wheel drive
[edit]All models are selectable four-wheel drive. The rear axle is driven as standard and drive to the front axle selected by the driver, through a hydraulically controlled clutch. This clutch is sprung on to give four-wheel drive and hydraulically disengaged to give two-wheel drive.
Axles
[edit]Most Fastrac axles have a central differential and epicyclic gearing reduction units built into the hub ends, where the wheel bolts.
The 7000 Series rear axle has a central differential and has in-board epicyclic gearing reduction units.
Axle locking differentials
[edit]A standard locking differential is provided in the rear axle of all machines.
100, 1000, 2000 and 4000 Series machines have a Detroit No-Spin-style differential lock in front axle.
3000, 7000 and 8000 Series machines have a driver-controlled clutch pack engaged locking differential.
PTO
[edit]A two-speed power take-off (PTO) is standard at the rear and a factory option at the front. Depending on the model either speeds of 1000/540 or 1000/750 are available.
Suspension
[edit]Multi-link suspension is fitted between the chassis and both the front and rear beam axles.
The front suspension on most machines uses four links, a panhard rod and anti-roll bar. On the 4000 series a V-link is used at the front.
The rear suspension uses two lower link and a V-link on top plus an anti-roll bar.
Hydropneumatic suspension is used on the rear of all models and on the front of the 4000 and 7000 series Fastrac. This is similar to that used on some Citroën cars.
Front axle steering
[edit]- 1000, 2000 and 4000 Series Machines
These Fastrac machines have hydrostatic steering similar to most agricultural tractors with only a hydraulic link between the steering wheels and the front wheels. This limits the maximum speed of these models to 50 km/h (31 mph), except now in Germany where 60 km/h (37 mph) is allowed.
- 100, 3000, 7000, 8250, 8280 and 8310 Series Machines
These machines have mechanical power steering similar to a large truck. This system gives a mechanical link between the steering wheel and the front wheels. Generally these machines have had a maximum speed of 65 km/h (40 mph) except some 100 and 3000 series machines having a maximum speed of 75 km/h (47 mph).
- 8290 and 8330 Machines
These machines have dual circuit hydrostatic steering allowing legal speeds over 60 km/h.
An automatic Global Positioning System-controlled steering system using a (Differential GPS) is available for the 3000, 4000, 7000 and 8000 series machines.
Rear axle steering
[edit]Rear wheel steering (four-wheel steering) is available as an option on 2000 and 4000 series machines. The electronic system has 5 modes of operation, and only allows four-wheel steering below 20 km/h (12 mph).
- Two-Wheel Steer
- Proportional
- True Track
- Delay Mode
- Crab Steer
Brakes
[edit]All models are fitted with large diameter external disc brakes at both front and rear individually on each wheel. An anti-lock braking system (ABS) is fitted on some models, depending on the maximum vehicle speed and legal requirements.
Auxiliary hydraulics
[edit]An auxiliary hydraulic system (hydraulic drive system) is standard on all machines. It is used to control the front and rear linkages and through quick connectors at the front and rear of the tractor to control and power implements.
Three-point hitch
[edit]A three-point hitch is standard at the rear of the machine and on option on front.
Rear trailer hitch
[edit]There are several types available depending on the country the machine is built for.
Cab
[edit]Traditionally the cab has been centrally mounted. Some models, the 7000 series and latter 8250, have the cab mounted at the rear of the tractor. The most recent[when?] Fastrac iteration, the 4000 series tractors, have forward sloping cabs, similar to those on combine harvesters.[2] All cabs have a full-size passenger seat and an air suspensioned driver's seat.

View on GrokipediaHistory and Development
Origins and Launch
In the late 1980s, JCB initiated the development of a revolutionary high-speed agricultural tractor to address the growing need in Europe for road-legal machines capable of efficient field-to-field transport without compromising draft capability. The project began with the construction of the first prototype in 1987, secretly developed under the office block at JCB Transmissions in Wrexham, North Wales, followed by 11 prototypes built through 1988 and 1989 for extensive evaluation.[5][6] JCB Landpower Ltd., the division focused on agricultural tractor production, was incorporated in 1988 to spearhead this initiative, establishing its manufacturing base in Cheadle, Staffordshire. A key prototype, designated P14, was publicly previewed at the 1990 Royal Smithfield Show in London, generating significant interest among farmers for its potential to revolutionize on-road mobility in agriculture.[7][8] Commercial production of the first Fastrac models commenced in June 1991, marking the official launch of the 100 Series, including the 125 hp and 145 hp variants, at JCB Landpower's Cheadle facility. These initial tractors achieved a top road speed of 40 mph (65 km/h), enabling large-scale operators to cover distances between fields rapidly while maintaining full tractor functionality.[9][10][8] The core design philosophy emphasized blending robust tractor utility with automotive-inspired performance, featuring all-round suspension, four-wheel steering, and a rigid chassis structure to deliver car-like handling at highway speeds. This approach, drawing from JCB's engineering expertise in construction machinery, positioned the Fastrac as an innovative solution for progressive farming operations requiring versatility across varied terrains.[10][9]Evolution Through Series
The JCB Fastrac's evolution has progressed through distinct series since the mid-1990s, each building on prior designs to enhance power, speed, and operational efficiency in response to agricultural and regulatory demands. The 2000 and 3000 series, introduced in 1998, succeeded earlier models with enhanced power outputs reaching up to 170 horsepower in variants like the 2170, alongside improved hydraulics providing flow-on-demand capabilities up to 100 liters per minute for more versatile attachment handling.[11][12] These series incorporated a 3-speed powershift transmission with 54 forward and 18 reverse gears, enabling smoother operation and higher productivity in field and transport tasks.[12] In the 2010s, the 4000 series, launched in 2015, emphasized greater road-going capabilities with top speeds up to 70 km/h (approximately 43 mph) and integrated advanced features like CVT transmissions for optimized fuel efficiency and traction.[13][14] Concurrently, the 8000 series debuted in 2017, delivering up to 335 horsepower from Cummins engines for superior reliability, full independent suspension across all wheels to reduce operator fatigue, and adaptations for EU road regulations including ABS braking and high-speed lighting to ensure legal compliance at 65-70 km/h.[15][16][8] The latest advancement came in September 2025 with the launch of the 6000 series at JCB's headquarters, introducing refined electronic systems for precise control and FPT N67 engines compliant with Stage V emissions standards to balance performance with environmental requirements.[17][18] This series features updated chassis structures and selectable four-wheel steering, further adapting the Fastrac to modern farming needs for year-round versatility.[19] Throughout these developments, production and R&D for the Fastrac have been centered at JCB's Landpower facility in Cheadle, Staffordshire, enabling iterative improvements that have sustained the model's reputation for high-speed, road-legal tractors.[9]Design and Engineering
Powertrain Components
The powertrain of the JCB Fastrac series is engineered for high-speed road travel and demanding field operations, delivering reliable power through a combination of diesel engines, semi-automatic transmissions, permanent four-wheel drive, and flexible PTO configurations.[1] Fastrac models predominantly feature turbocharged inline-6 diesel engines, with displacement varying by series to match performance needs. Early production models, such as those in the 2000 series like the 2140, utilized a 5.9 L Cummins engine producing 142 hp at 2,200 rpm.[20] The 3000 series adopted 6.7 L Cummins QSB6.7 engines in later models, while the 4000 series uses 6.6 L AGCO Power engines, delivering outputs from approximately 155 hp in base configurations to 217 hp rated (235 hp max) in higher variants like the 4220.[21] Starting with the refreshed 4000 and 8000 series in the mid-2010s, JCB transitioned to AGCO Power engines for better performance tuning and Stage V compliance in recent models. The current 8000 series features 8.4 L AGCO Power engines, rated at up to 335 hp with peak torque of 1,328 lb-ft (1,800 Nm), emphasizing efficiency for heavy-duty tasks; earlier models used 8.3 L Cummins QSC engines up to 260 hp.[16][15] Following 2014, engines across the lineup incorporated Tier 4 Interim/Final emissions technology, including selective catalytic reduction (SCR) systems, to meet stringent environmental regulations while maintaining power density; as of 2025, the 6000 series uses 6.7 L FPT Industrial NEF engines compliant with Stage V/Tier 4 Final standards, achieving 335 hp and 1,033 lb-ft (1,400 Nm) of torque for enhanced productivity.[22][2] The transmission system employs JCB's proprietary Powershift or P-Tronic semi-automatic design, which facilitates clutchless gear changes for smooth operation at elevated speeds. Configurations typically include a 6-speed synchromesh gearbox combined with a 3-range section and 2-speed powershift, yielding up to 36 forward gears and 12 reverse gears, with top speeds reaching 65 km/h in high range.[23] Later models, such as those in the 4000 and 8000 series, offer optional continuously variable transmissions (CVT) like the V-Tronic, providing infinite speed adjustment from 0 to 65 km/h with dynamic torque management for optimal fuel use during transport and fieldwork.[24] The 6000 series features the ZF Eccom 3.1 stepless transmission. This setup ensures precise control without interrupting power flow, supporting the Fastrac's reputation for car-like drivability. Permanent four-wheel drive (4WD) is standard across the lineup, distributing torque equally to front and rear axles via a center differential for superior traction on varied terrain.[20] The system maintains stability at highway speeds up to 65 km/h, with selectable engagement modes in some series to optimize performance for road or field conditions.[14] Power take-off (PTO) options include independent electro-hydraulic rear units operating at 540/1,000 rpm, driven directly from the engine for consistent implement power regardless of ground speed.[21] Front PTO is available as a factory option on select models, matching rear speeds for versatile attachment use. Ground-speed PTO variants, synchronized with wheel rotation, support high-speed operations such as crop spraying or mowing at rates up to 50 km/h, enhancing efficiency in large-scale applications.[25] The powertrain's integration with the chassis suspension contributes to overall stability during high-speed maneuvers.[17]| Series Example | Engine | Displacement | Rated Power (hp) | Transmission Type | Max Speed (km/h) |
