Building on from the success of the JCB TM320s, the TM420 was on show at Punchestown.

Additional features on the TM420 include increased lift capacity, regenerative hydraulics and tougher chassis and boom construction with larger pins and bushes for its centre pivot and loader.

Heavier-duty axles offer permanent four-wheel drive.

Now shod on 26in rims, it is capable of accommodating larger tyres than previously seen on the TM320s.

Its engine and transmission remains the same as before, using JCB’s EcoMAX 4.8 litre engine, coupled with a six-speed powershift transmission, which can be operated in manual or automatic mode.
