Toro Hydroject

The Hydroject is a pedestrian machine that aerates by injecting water at high velocity to penetrate the ground. The water is delivered in 10-millisecond pulses at extremely high pressure. Working at 5,000psi, the water is injected at a speed of 966km/h.
It punches through the soil to relieve compaction, improve drainage and gaseous exchange and — as an extra bonus — flush out damaging materials, such as salts, that would affect the overall health of the turf. It also provides an effective route for moisture and nutrients to the roots.
It’s the only water-injecting aerator on the market and was developed in response to the need to aerate deeper than the 75mm of conventional core aerators. The Hydroject will penetrate down to 150mm and with repeated shots, it is possible to penetrate as
far as 500mm. It’s easy to use, having the necessary controls on a panel at the handlebars.
First developed in the 1990s, when it was seen as a breakthrough in aeration technology, the Hydroject has recently been upgraded and now includes a Kohler 27hp engine. It offers four spacing control settings — 38mm, 76mm, 115mm and 150mm. Depending on spacing and speed, an experienced operator can cover the ground at a rate of 2,400sq m per hour. The latest model, the 3010, has a dosing unit, so wetting agent can be added to the water.
A lot of thought has gone into the design of the Hydroject. It needs to be tough. The internal high-pressure water components are made of corrosion-resistant materials and an on-board, five-micron filter protects internal components from premature wear. Accessories include a transport trailer, enabling the machine to be towed to work by a utility vehicle, and a dosing system for supplementing the pulses of water with wetting agent. There’s also a lift kit to enable operation in a raised position. This creates larger holes to receive top-dressing materials.
It seems Toro thought of everything when it designed the Hydroject, and because it uses no mechanical means of ground penetration, there is never going to be a broken tine.
