In moving from Stage IIIA to Stage IV emission compliance, Househam Sprayers is changing its engine supplier from Caterpillar to MTU. First self-propelled Househam to get MTU power is the flagship model, the 6,000-litre/36m Merlin M6-36, and over time the Lincs firm’s smaller SP sprayers will gradually follow suit. Other points of interest on the new M6-36 are the use of secondary disc braking and various modifications to the machine’s suspension: previously there was a fixed link axle at the rear, whereas there’s now an A-frame axle at both front and rear. The end suspension result, says Househam, is reduced stress in the chassis and a better ride for the sprayer operator. Price of a fully specced M6-36, complete with stainless steel tank, is about £230,000.
