A three-wheeler, this sprayer has a jockey wheel at the back to give it total manoeuvrability and maintain the boom at the right height for spraying.
Our tester spots the boom has no breakback mechanism. “There’s no room for carelessness,” he says. But he likes the fact the boom folds vertically to give access through narrow gateways. We reckon, however, an R-clip to hold the booms vertical would be an improvement on the current “blood blistering” jaw-type clips. The handles adjust for comfort and detach for transportation.
The pump on the Scout has a general working pressure of three-bar, giving a flow of 14 litres/min. Liquid is re-circulated, taking a little of the pump capacity but ensuring nothing settles out of suspension. A sump in the bottom of the tank serves as a drain-down point. The 12A battery gives approximately three hours of use and is supplied with charger. A quick-release connection is supplied for a hand lance.
In use we find the flow switches off immediately. “There is a diaphragm check valve so as soon as you switch off, the valve snaps shut and all the nozzles are instantly off,” explains the tester. “Pressure regulation is fairly crude but perfectly effective.”
What really impresses our testers, however, is the optional foam bout-marker. It’s a new product from Sherriff and, to our tester’s mind, is “absolutely brilliant”. “Some bout markers are just expensive chunks of machinery,” he says. “But this is a very simple system and value for money.”
Called Turf Tracker, the marker drops blobs of foam from the ends of the boom to create an easily visible track.
The Cub, as the name suggests, is the Scout’s little brother. It works on a similar principle and has the same width boom but comes with a 25-litre tank and is aimed at smaller areas.
Our tester notes, “The Scout has a jockey wheel to fix the height whereas this is a bit ‘up and down’, and with the smaller tank it covers a much smaller area and needs refilling more often. That’s fine, providing you don’t expect it do to the same job as the Scout.”
Without a jockey wheel, our tester finds the Cub has to be lifted a little before pushing. “It is more difficult to manoeuvre than the Scout. I’d much rather use the bigger one,” he says.
Neither machine left tyre marks, even though the ground was soft.
