Why do I need one?

All horse owners must be aware of the need to control weeds. Ideally, you should identify all the plants that occur in your paddocks and tackle the undesirables, but make the most of the ones that enhance the grazing and palatability for your horse. As well as poisonous plants there are those that are just a nuisance. Spraying is the accepted method for weed control in many instances.

You should follow the chemical manufacturer’s guidelines for where and when to spray, paying particular attention to the amount of time after spraying that you need to leave the paddock clear. Whether you’re spraying over a wide area with a boom, or spot-treating weeds with a hand-lance, a dedicated trailed sprayer tackles the job with maximum convenience and speed.

All applications

Whether it's spraying arable headlands, spot control in grassland or around buildings and sheds there will always be a use for an on-board sprayer.


Product Features

A rotational moulded tank and a high quality pump designed for use with chemical are at the heart of a good, reliable spraying system.  Fitting of the tank is very quick and straightforward, using the 'T' bolts supplied. The unit also comes with a complete wiring harness with in line fuse. All booms are height adjustable and have a break-back facility.  All nozzles can be individually swithched on and off.  The hedgerow nozzle is very useful for spraying  electric fencelines and the bottom of the hedgerow/wall.
