Bobcat midi excavators 337 to E85 – the 4.8 to 8.6 tonne class of the skid-steer inventor: 337 to 442 as the range of the 2000s, E63 and E85 as E range from 2010, Long Arm as boom variant

Bobcat's midi excavators complement the minis upward: machines of 4.8 to 8.6 tonnes for sewer work, demolition and rental that Bobcat has sourced since the 1990s at first from the partnership with Kubota and since 2007, under Doosan, from its own development at the Pontchâteau plant in France. The type logic shows two generations: the three-digit 337, 341, 435 and 442 of the 2000s order the size in ascending order, with Long Arm and Standard Arm as boom variants; the E range from 2010 gives the weight class in hundreds of kilograms in the number – E63 about 6.3 t, E85 about 8.5 t. The engines come from Kubota (V2003 of 2.0 litres in the 300s) and Deutz (BF4M 2011 of 3.2 litres in the 400s), four-cylinders at 2,100 to 2,500 rpm; the E models carry Kubota and Doosan engines to emission stage IV.

The register lists 8 versions with 35.7 to 54.4 kW from four-cylinders of 2,001 to 3,210 cm³ and operating weights from 4,788 to 8,608 kg.

In the midi class Bobcat is a mid-sized supplier behind Kubota, Takeuchi, Yanmar and Caterpillar but strongly represented in rental fleets because skid steer and excavator come from the same dealer; the E85 is the brand's largest excavator.

On used machines, operating hours, play in boom, stick and offset-boom bearings, the condition of undercarriage and rubber tracks, leak-free cylinders and swivel joint and parts supply through the Bobcat network, Kubota and Deutz count.
