All the latest take a bow

The scene is set for Ciba Agricultures annual Sprays and Sprayers event. Held at the companys Whittlesford, Cambs, site on Jun 27/28, it has all the ingredients of an entertaining and informative show. Andy Collings provides a preview

THIS years Sprays and Sprayers event occurs at a time when sprayer makers are, by their own admission, enjoying a bonanza.

According to the Agricultural Engineers Association, mounted and trailed sprayer sales have risen by as much 10% in the past year. And the market for self-propelled sprayers also looks buoyant.

Current predictions from the AEA are for about 1600 mounted, 325 trailed and 230 self-propelled sprayers to be sold in 1995. Such demand has encouraged manufacturers to invest in development of their wares, with the result that several new models make their debut at Sprays and Sprayers.

Latest from Knight Farm Machinery is a 3000-litre trailed sprayer equipped with a Degania sleeve boom. Though the sprayer unit, with its chemical induction hopper and clean water tank are by now considered standard features, the new development is found in the boom construction.

Protection for the inflated sleeve and spray nozzles is provided by a series of vertical deflectors, with the sleeve itself suspended from the top bar of the boom. It is a design which is also claimed to be stronger than previous models.

Boom-line recirculation

Knight is also set to launch a boom-line recirculation system which continually presents chemical to nozzles along the booms entire length, so positive, instant starts can be made when spraying. Unlike similar designs which pump the chemical around the spray lines, the Knight system sucks the liquid – providing a negative pressure and ensuring chemical does not dribble out of the nozzles. The flow is reversed when spraying commences.

A range of lightweight 12m, 15m and 16m booms for Berth-ouds Mack mounted sprayers are set to make their debut at the event. Aimed at the vegetable grower where crops on just one side only may need to be sprayed, the new booms can be operated with one boom folded in without affecting stability, claims the maker.

For farmers and contractors looking to get more use from their machines, the demount option will always be a consideration. Latest contender for the demount market is Hydro Chafer, which intends to display a new range of demount kits. Available with tank volumes of up to 2000 litres for use with the JCB Fastrac and up to 3000 litres with Clayton Buggies, boom sizes can be specified.

For the true self-propelled enthusiast, the launch of the Gem 2000-litre Sapphire could be worth taking note of. The second delve into the SP market for the company, the Sapphire follows hard on the heels of a 2500-litre version introduced last November.

Weighing 750kg less than its larger stablemate, the new 2000-litre with its £47,500 price tag, is aimed at the medium to large farmer. Power is provided by a four-cylinder, 110hp John Deere engine driving through a hydrostatic transmission.

Lincs-based Househam is set to launch a hydraulically adjustable track-width system as an option for its range of Imp, Sprint and Swift self-propelled sprayers.

Track widths can be changed from 60in to 72in or 68in to 80in and within any 12in variable to suit requirements. Controlled from the cab, the operator drives forwards as the system is initiated – the new width setting is then hydraulically engaged and locked in position.

And for orchard spraying enthusiasts, Tecnoma has developed the Turbocol – a mist-delivering system which directs chemical horizontally, rather than through an arc as with conventional mist blowers. Units can be assembled to a height of 4m. &#42
