These are the largest backhoes in the LEWIS range. More heavily built than the 300 range, the 400 range are for the largest of compact tractors as well as agricultural tractors of 60 HP+. These
backhoes are used in applications where increased digging depth and lift capacity are a must.
The 420 is a centre pivot machine with a digging depth of 3.3m, butis only available for larger tractors with a CAT, 3-point linkage fitting.
