In order to make the best use of every drop of precious fuel, gravitational forces were used to make lowering and retracting the boom more energy-efficient and efficient.
In addition, the hydraulics operate with load sensing, drawing power only when required to save fuel.
In the cab of the JCB TM420, there is a button to release pressure from the front and rear working hydraulic circuits, ensuring quick and safe attachment changes.
End damping of boom movement during extension/reversal improves material retention and makes work cycles smoother.
High-flow pipework provides greater flow to the boom; a system ideally suited to attachments requiring high flow, such as silage cutters and straw shredders.
For even better load retention when driving fast on road or off-road, opt for the automatic bucket suspension system (Auto SmoothRide = SRS). The automatic SRS activates when the speed exceeds 2.5 mph (4 km/h). This system can be activated manually, at any boom position.
The high back-off power-assisted brakes reduce frictional resistance when driving on the road and when handling, increasing fuel efficiency.

The JCB TM420 is equipped with a JCB EcoMAX Tier 4 Final engine with a variable geometry blade turbocharger. This 4.8-litre, 145hp (108kW) engine provides a boost in performance - such as a high 560Nm torque at low engine speeds. This, in turn, means optimum engine flexibility, cycle times and traction, along with fuel-efficient transmission and hydraulic matching.rnFor exceptional traction and performance in soft, muddy terrain, we install 4WD as standard. For even better performance in difficult conditions, choose limited-slip differentials.rnYou can vary the flow rate on the fly - perfect for a straw chopper or sweeper, while a second optional boom auxiliary circuit caters for a wide range of additional attachments. The constant flow hydraulics are intuitive to operate, with flow rates displayed on the in-cab screen and adjustable on the fly.rnThere is a selectable torque converter lockout in gears four to six on this telehandler to increase efficiency and productivity.rnThe 4.1t capacity is designed to increase performance and productivity

The cab screen on the JCB TM420 wheeled telehandler displays daily checks including coolant level and engine oil level.rnThanks to our graphite-impregnated bronze bushings, we have achieved extended lubrication intervals of 500 hours to maximise machine availability.rnIn this wheeled telehandler, the diesel and DEF fluid tanks are easily filled from ground level. Both tanks have built-in pre-filters in the filler ports for protection against dirt and debris and also have special keys to protect against accidental cross-contamination.rnSelf-lubricating boom operating pads and dry lubrication of the boom ensure true maintenance-free operation.rnFor ease of servicing, the engine oil, hydraulic oil and fuel filters are centrally located. The air filter is also easily accessible and is a two-piece design, simplifying cleaning. The JCB TM420 is equipped with a large, wide service bay, accessible through the gas spring-lifted bonnet. This arrangement allows quick and easy inspection of the three sides of the engine.rnExcellent cab access, with three points of contact and ergonomically positioned hand grips and steps. Hose burst check valves (HBCVs) on the cylinders protect against the boom falling in the event of hose failure. Adaptive load control technology automatically controls the hydraulics, helping to maintain the machine's longitudinal stability.rnFor the protection of your investment, the TM420 is fitted with LiveLink telematics as standard, tracking the machine's position in real time, and an optional immobiliser key as an added safety feature.rnOur optional reversing camera displays an unobstructed view of the field behind the machine on the colour on-board monitor of your TM 420. A reversing alarm is fitted as standard on the JCB TM420 to warn bystanders.

The TM420 telescopic wheel loader's rigorous testing programme includes subjecting the chassis, boom and other key components to heavy loads, as well as repeated thousands of gearbox engagements in typical agricultural work cycles.rnThe centrally-mounted lift, tilt and reach cylinders eliminate boom torsion and are held in place by centrally-mounted special bore castings for even greater structural integrity. rnWe make JCB's own hydraulic cylinders, cabs, axles, gearboxes and engines - all designed to ensure that these assemblies work together perfectly in harmony and achieve optimum reliability.rnWe make JCB's own hydraulic cylinders, cabs, axles, gearboxes and engines - all designed to ensure that these assemblies work together perfectly in harmony and achieve optimum reliability. rnMaximum resistance and rigidity is ensured by the special design central joint, which takes vertical and horizontal loads.rnThe wide-channel cooling block with optional hydraulic reversing fan removes accumulated debris. The reversing fan can be set by a simple switch to manual or automatic operation.rnThe cast-iron rear counterweight of the telescopic wheel loader further protects against impact damage; the recessed rear lights mounted above the counterweight are well protected.

Our new HVAC (heater, ventilation, air conditioning) system provides operators with long-lasting comfort and makes it easy to maintain attention on the job; the 3-speed heater fan serves to maintain the correct temperature for work all year round, from cold winter weather to hot harvest days.rnDamping the end movements of the boom during lift, extension, reversing and bucket dumping reduces the impact on the operator and the machine. rnThe cab of the TM420 telescopic wheel loader is large and spacious, with plenty of storage space for personal belongings and work essentials.rnThe colour LED screen on the dashboard provides operators with useful information such as operating hours, fuel reserve, fuel consumption since last refuelling and average instantaneous fuel consumption. The DEF (exhaust gas disposal fluid) level and any additional information and times until the next service interval are also shown.rnThe illuminated buttons ensure that the controls are quickly and accurately recognised, even in the dark.rnOptional air conditioning makes it even easier to achieve the right temperature in the cab of this telescopic wheel loader.
