High clearance front boom self-propelled sprayers from US manufacturer Hagie have been refreshed with a new cab and several precision farming technology options from parent company John Deere.

The Hagie STS line-up of single tank machines has been slimmed from four to three, with the smallest capacity model from the current range dropped as a bigger capacity model completes the line-up.

The STS line available to order from mid-year 2021 comprises the 4,500-litre (1,200 gallon) STS12, which comes with a 300hp engine, and two larger frame machines – the 6,000-litre (1,600 gallon) STS16 with 400hp; and the 7,570-litre (2,000 gallon) STS20 also with 400hp.

9.0-litre John Deere PowerTech engine

As with current versions, the engine is mounted outback with the solution tank in the middle and the cab in a forward control position. But the engine is now the 9.0-litre John Deere PowerTech engine across all three models, powering a four-wheel drive hydrostatic wheel motor transmission on slim leg axles with all-wheel steering.

Working widths of the front-mounted steel and aluminium booms are unchanged at 27m, 30m, 36m and 40m (90ft, 100ft, 120ft and 132ft) and are equipped with a Norac sensing system designed to maintain the required height over ground undulations and through turns.

John Deere ExactApply system

However, in addition to a regular sprayline installation, John Deere’s ExactApply system is available as a new option, providing twin nozzle assemblies, one in a fixed position and four on a turret, with individual spray on-off control.

This enables the operator to put pairs of nozzles in place across the boom before setting off and then quickly switch between them – or use both at the same time – using a control switch in the cab.
This facility can be used to change from one tip size to another or from a fine to a drift-supressing design, for example.

Most desirable system pressure maintained

An automatic speed-related control system, switch between two nozzles of different sizes – either A, B or A and B together – will maintain the most desirable system pressure in situations where working speeds cover a wide range because of terrain, surface conditions and other factors.

AutoTrac satellite guidance, ‘touchy feely’ RowSense guidance along crop rows and the new AutoTrac Vision are also available on the new Hagie sprayers, which now have a Deere-sourced cab with improved visibility from the operator’s seat.
