LATEST ROTARY CULTIVATORS CAN TAKE DOUBLE THE POWER

Dowdeswell has extended its range of Powavator rotary cultivators with three models suitable for tractors producing up to 260hp at the power take-off. Previously, the implement was only available for tractors developing a maximum of ~30 PTO horsepower.

Known as the Powavator 260 series, the new models come in working widths of l2Oin (3.05m), l4Oin (3.56m) and l6Oin (4.06m). All are of heavy-duty construction, engineered to deliver high workrates in the toughest of working conditions behind tractors equipped with 1,OOOrpm PTO speed and Category 3 linkage.

A novel feature on the new machines is a split input shaft driving gear trains at both ends of the main rotor, which helps to balance power delivery and weight distribution. The splitter gearbox has a safety clutch and offers rotor speeds of l87rpm, 222rpm and 265rpm at 1,OOOrpm PTO input speed, selected by an automobile-style gear change lever.

Users have a choice of traditional 'L' bladed, spiked, speed-bladed or stubble rotors. The first-mentioned has a cutting, lifting and turning action, ideal for chopping vegetation and working down most soil types. The spiked rotor has straight tines designed for tougher, drier soils where a percussive action can help<

break down clods. The speed-bladed rotor is an alternative to the spiked rotor and is suited to deep cultivations, particularly on potato land. The stubble rotor has rectangular tines with a slight twist in the blade close to its mounting point. The resultant cutting, churning action has proved very successful breaking down and mixing in stubbles.

Degree of soil finish can be altered on screw-adjusted rear trailing boards, spring-loaded to minimise stress or damage in stony or heavy conditions. Options for all three machines include a choice of either twin depth wheels, a crumbler roll or a packer roller at the rear of the machine, front disc openers, a rear linkage for a bed former, and a front frame equipped with subsoiler legs.

Prices of the Powavator 260/l2Oin, Powavator 26O/~4Oin and Powavator 260/l6Oin are from ~2,O7O, L13,042 and £14,850 respectively.
