The JCB 4190 is a tractor in the category of agricultural tractors, manufactured by JCB. This model belongs to the four-wheel-drive variant and is powered by a six-cylinder engine from AGCO Power. The engine designated 66AWF has a displacement of 6,600 cm³ and reaches its rated speed at 2,100 rpm. The drivetrain design is optimized for high traction and continuous adaptability, supporting use in various agricultural scenarios.
With an output of 189 hp and a maximum torque of 850.1 Nm, the JCB 4190 provides sufficient power for demanding field work and the transport of heavy loads. The high torque enables efficient movement of large implements or trailers without overloading the engine. Turbocharging with intercooling ensures optimal combustion efficiency and keeps engine temperatures within the permissible range. The ground clearance of 450.1 mm allows traversal of uneven terrain and high crop residues without damaging the vehicle's underside. The two-range continuously variable transmission enables precise speed adjustment, which is particularly advantageous for variable working speeds.
Within the model series, the JCB 4190 is positioned as a model with high power density. The combination of the powerful six-cylinder engine and the continuously variable transmission makes it suitable for tasks requiring constant power delivery across a wide speed range. The technical design with four-wheel drive and the specified ground clearance supports operation in difficult soil conditions. The specific engine configuration with 6,600 cm³ displacement and turbocharging ensures robust power transmission, designed to meet the requirements of modern crop farming and soil cultivation.
JCB – other models: the collective page of farm equipment outside the named ranges, from the Fastrac 145 and 155-65 through the 2135, 3185 and 3230 Xtra to the 4160
This page gathers the JCB farm machines the register could not assign to a named range – above all the Fastrac, the tractor with which the backhoe-loader maker from Rocester in Staffordshire entered agriculture in 1991, and the Agri telehandlers with which JCB shaped the farm-loader market. The type logic of the Fastrac: the early types 145 and 155-65 give the hp class (and the top speed in km/h), the 2000 and 3000 ranges of the 2000s the series in the first digit and the power in the following ones (2135 about 135 hp, 3230 about 230 hp), Xtra the equipment line; the 4000 (4160 to 4220) and 8000 (8250 to 8330) ranges since 2005 and 2014 follow the same logic with stepless transmission. The Fastrac is a systems tractor with full suspension, disc brakes and central cab that is the only tractor approved for 70 km/h. The telehandlers give capacity and lift height in the digits – 531-70 3.1 t to 7 m, 536-70 3.6 t to 7 m, 560-80 6 t to 8 m – Agri, Agri Super and Agri Pro the equipment lines. The engines come from AGCO Power (Sisu) in the Fastrac 4000 and 8000, from Perkins and JCB (Dieselmax, EcoMax) in the others.

The register lists here 130 versions with 12.9 to 185 kW from three- to six-cylinders of 784 to 8,268 cm³, unladen weights from 840 to 11,870 kg, gross weights from 1,360 to 16,000 kg, lengths from 2,980 to 6,030 mm and widths from 1,520 to 2,600 mm.
The Fastrac is the tractor of contractors and haulage farms in Britain, Germany and Scandinavia; the Agri telehandlers are market leaders of their class in Europe.
On used Fastracs, operating hours, suspension and brakes (disc brakes take road wear), transmission (powershift or stepless), engine and electronics count, on the telehandlers boom, wear pads, hydraulics and axles; parts run through JCB dealers.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
