<p>The implement harrows, tamps, sows and fertilises in a single pass, the bulk of its weight being taken by the tractor lifting arms. The covering and fertiliser tools are mounted on a front angle-iron, on which they are adjustable, together with the seed drills and harrow implements. The frame can be used with vibratory harrows. The covering tools can be replaced by 9 to 12 broadcasting tubes, for fertiliser.</p> |
