Sprayer rises to the occasion

THE most unusual feature of the Mac 160 Field Leader self-propelled sprayer is the way the saddle-shaped tank and the rest of the machines spray system can be raised on a subframe to give access to the engine and transmission beneath.

The arrangement allows both engine and tank to be positioned half way between the axles for consistently even weight distribution, regardless of whether the 4500 litre tank is full or empty.

Commissioned by Northants spraying contractor Greg Wilcox, the newly-completed machine was shown at last weeks Sprays & Sprayers event by constructor Paul McAvoy.

Power is provided by a 160hp Deere PowerTech engine, with mechanical four-wheel drive transmitted through a six-speed powershift and JCB axles.

Air suspension is designed to give the Field Leader an easy ride and fast travel capability, while 54in row-crop wheels and tyres help crop clearance. Selectable four-wheel steering improves the big machines manoeuvrability.

John Deere provides the forward-control cab, behind which a roomy platform gives the operator access to chemical induction hopper and spray system controls. Its counter-balanced by a Landquip-supplied 42m Alu-light aluminium boom.
