JCB’s new TM 420S telescopic wheeled loader delivers performance, productivity, and comfort

JCB TM 420S telescopic wheeled loader

The new JCB TM 420S telescopic wheeled loader sets new industry benchmarks for performance, productivity, and comfort, boasting the most powerful engine in the category and an industry-first 50km/h, eight-speed powershift transmission with torque converter lock-up in all forward and reverse gears.

Claas Harvest Centre product manager (JCB) Steve Gorman says telescopic wheeled loaders combine the power and articulated steering of wheeled loaders with the manoeuvrability and telescopic reach of a telehandler.

"TM telescopic loaders are already highly regarded by farmers and agricultural contractors for their versatility in restricted spaces, and this new series sets the bar even higher," he says.

"Fitted with a huge range of attachments, they are capable of performing a range of tasks, including silage rolling, hay stacking, lifting potato boxes, loading bulk seed and fertiliser bags, and intensive feeding operations."

The TM 420S is powered by a 4.8-litre JCB 448 DieselMAX engine that delivers lively performance and silage clamp climbing ability with a maximum output of 173hp, 690Nm of torque, and an impressive power-to-weight ratio of about 17hp per tonne.

"The engine meets EU Stage 5 emissions standards via a clever single-canister DPF/SCR system," Steve says.

"This minimal requirement comes largely thanks to the inherent efficiency of the engine, which also makes a significant contribution to fuel economy. This is further enhanced by the ‘autostop’ feature that shuts down the engine after a pre-determined period at idling speed."

The TM420 boasts a maximum lift of 4.1T and a maximum reach of 5.45m

JCB’s new 50km/h eight-speed Powershift transmission is based on its proven six-speed unit but has two extra forward gears for optimum traction in all conditions and smooth progression through the ratios.

"The high-speed gearing allows rapid yard-to-field and farm-to-farm travel and a quieter and more economical 40km/h cruise at low engine speed," Steve says.

"The torque converter lock-up in every gear, including the four reverse speeds, ensures optimum performance during repeated forwards-and-backwards work or when travelling on the road, especially when tackling hills or towing."

The transmission can be operated manually using the joystick buttons or by via an automatic power-shift for gears five to eight.

"In auto mode, the transmission responds to light use of the accelerator pedal by shifting up and down at a relatively steady engine speed for optimum fuel economy," Steve says.

"More aggressive pedal use results in delayed upshifts to exploit the full power and torque available at higher revs for maximum acceleration and productivity." A heavy-duty chassis, 10-stud axles, 660mm diameter tyres, limited slip differentials, disc brakes in both axles and an electric parking brake complete the package.

The TM420 boasts a maximum lift of 4.1 tonnes and a maximum reach of 5.45 metres.

Twin hydraulic piston pumps deliver an on-demand flow rate of up to 160 litres per minute using only modest engine power.

Regenerative hydraulics exploit the weight of the boom to bring it down faster but still under safe control.

The new Command Plus cab features a one-piece windscreen that sweeps up and over the operator’s head, a redesigned internal safety grille, larger rear three-quarter windows, a rear-view camera, and an optional roof wiper.

"All told, forward visibility has been increased by 13% while overhead visibility has been increased by 52% for even easier placement and retrieval of stacked items, such as bales and potato boxes," Steve says.

"Inside, the new ‘memory’ steering column can be pushed away to enter or leave the cab more easily, while the illuminated cab steps and delayed ‘lights off’ function ensure safe approach and exit at night." 

The assignable ‘hot key’ button on the hydraulics control joystick can be used for a number of functions, including switching between transmission modes, torque lock-up engage/disengage, auxiliary hydraulic valve control, radio and phone controls, or a master switch for the work lights.

A mobile phone holder can be added to the switch panel on the right-hand pillar.

The cab includes a pressure release button for front and rear hydraulic services, ensuring quick and safe changeover of attachments.

The 420S can be equipped with the Pro Edition specification, which adds the JCB Smoothride boom suspension, transmission belly guard, and a variable-speed reversing engine coolant fan to the package.

Accompanying these productivity-enhancing features are a chromed exhaust stack, 360-degree LED cab- and boom-mounted lighting system, twin flashing beacons, an in-cab storage box, toolbox, grease gun, and Bluetooth radio.
