Allman X-15

It's obvious our tester knows a thing or two about sprayers — including the type of abuse a knapsack can expect. The X-15 is strong. It's well engineered. We reckon it should provide reliable performance for many years.

The operator’s manual is easy to read, has clear illustrations and provides information on calibration. In the box there is also a bag of bits — piston spares — though we think by the time this sprayer needs spares you are likely to have lost them. And what’s this? Our tester pulls out a spanner. “Typical of Allman,” another tester says. “Everything you need is provided. I am impressed that it has spare washers for the pump, although you would need to stow them carefully.”
With straps pre-fitted, the unit is almost ready to go. The filler hole is wide (115mm) and close to the edge to facilitate easy filling and the carrying handle is useful for lifting the sprayer around. The filter is very deep — the deepest we’ve seen.
“It’s a good depth. The base is solid, but I don’t think that will be a disadvantage because it is such a deep filter and the sides are mesh,” says our tester.
The pressure mechanism on the X-15 has a large-capacity chamber to reduce pump strokes. Another tester investigates the lance and trigger. “It’s got an in-line filter but it’s metal. I prefer nylon,” he says. The trigger is fitted with a constant-flow locking device. The pressure valve has two springs: one-bar and two-bar pressure. There is a clip for storing the lance.
The handle is heavy-duty and can be fitted on to the thick metal bar at the base of the sprayer to enable left- or right-handed operation. “This is one strong sprayer. It isn’t going to go wrong,” comments a tester. “If anything, it’s a bit over-engineered and my only concern is that adds to the weight.”
The X-15 has been tested for more than 2,500 hours. The sprayer weighs 4.8kg empty. The capacity of the polyethylene tank is 15 litres.
First-class straps are fitted to the Allman. They are wide and thick, with plenty of padding, and are stitched for strength. Our tester finds them comfortable but has trouble pumping. “It’s got an extremely smooth action but is about four or five inches too short and is a bit too close to the body,” he reports.
The Allman comes with four types of nozzle: fan, flood, cone and an adjustable nozzle.
A good selection of useful accessories is also offered for the X-15, including flow-calibration bottle, spray hood, two-nozzle lance for better penetration in perennial crops, lance extension and two-nozzle and three-nozzle booms.
