The tractor of the Year 2022 Awards, held at the recent EIMA show in Bologna, handed out a brace of gongs for the Green Giant John Deere.
Designed for use in all types of crops including viticulture, the machine offers the ability to spread conventional materials like urea, superphosphate, lime and chicken manure to the rear, while also incorporating a front-mounted discharge conveyor for banding products like compost, vermicast or mulch - without any changeover time.
Centred around a singleaxle chassis, a 2 cubic metre stainless steel bin is set low and narrow to offer precise manoeuvrability in the vineyard or orchard. Overall dimensions of 4.75m long, 1.6m wide and 1.42m high, means the machine can move easily under canopies, alongside being easily loaded by smaller, specialised tractors. In the base of the bin, an 800mm wide belt conveyor can move loads rearwards or forwards at the flick of a switch.
Material brought forwards meets a horizontal cross conveyor, that delivers to the right hand side, so clearly visible to the operator. Products like mulch can be dropped in a windrow, or placed in piles, while an instant start/stop function controls both conveyors simultaneously, meaning the cross conveyor is pre-loaded for any restarts.
In the case of the rear discharge mechanism, twin spreading discs sit on spinner tubes driven by individual hydraulic motors, with stainless steel used throughout. An in-cab controller allows the operator to select spreading or banding, in the case of the former, using target application rate, product density and tractor centres to deliver the required application rate automatically.
Key components are protected by front and rear nudge bars, while the durability of the machines is enhanced by attention to detail in the final finishes. Painted areas are subjected to an initial grit blasting process to remove any trace of grease or contaminants, before a pure zinc thermal arc spray coat, a primer coat and a two-pack epoxy paint final finish.
Optional extras include a swivel hitch for difficult terrain, LED lighting for road work, axle risers and tyre options, alongside oil cooling and temperature monitoring. For job specific spreading tasks, there are also a right-side only spinner or centre-discharge blocking options.
