VIDEO: Australian Kelly MPH cultivator is said to be fast and effective

Weaving Machinery had on its stand what was probably the most unusual cultivator at LAMMA – although it only had room to show one section of the machine (hence the working shot shown here).

It’s called the Kelly MPH (as in multi-purpose harrow) and was designed in Australia 25 years ago. Several units are working in Denmark, where the machine is now made under licence.

It uses four sets of flexible chains-and-discs in a diamond-shaped pattern to perform really high-speed work – 7-9mph is said to be typical. What’s unusual is the small diameter of the discs and the fact that each of the four chains moves at 43% to the direction of pull. Working depth is typically 2-6cm and fuel consumption is just 2.5-3.5 litres/ha

Where would you use it? Either straight into stubble to get a stale seed-bed or for pulling down ploughed land. Either way, it’s said to be fast and indestructible and happy to work in damp conditions.

Folding and unfolding is a joy to behold, with long ram-operated arms draping the chain-and-disc units across the main frame rather like you’d drape coloured lights on a Christmas tree.

Heavy duty bearings are fitted at the ends of the chains, says the company, with wear and maintenance costs said to amount to 59p/ha. There’s also a 1000-hour/five-year warranty.

Three models are available – a 6m version at £33,000, a 9m at £46,000 and a 12m at £60,000. Power requirement is 120hp, 200hp and 300hp respectively.
