Effect of tine velocity The earlier prediction models did not consider the inertial effects of the soil on the tine forces. In later work, an inertial factor was introduced which takes into account the volume of disturbed soil and the amended model includes a force term which incorporates the kinetic energy imported to the soil.

tines were used to develop an equation to estimate the maximum sustainable pull exerted by a land anchor, together with a model of the static equilibrium conditions acting at the anchor components.

Spreadsheet calculations The procedure for the calculation of implement forces is not mathematically difficult but requires considerable computation. In addition, the final results depend upon a number of interdependent and complex expressions and derivations which require some experience in their use. In order to facilitate the calculations, spreadsheets are particularly useful and a number has been prepared by the authors to enable the Fig. 5a.

Fred Walters (brimmed leather hat in centre of photo) is one of the country’s pioneering farmers in the development of the planting and growing of willow as a fuel crop. On our day visit to Sutton Grange near Retford, we were taken through the growing cycle from seed bed preparation to harvesting. The planting machines were demonstrated – he said that a hard brimmed hat was essential when handling three and four metre long whips of willow on the planting machines! The long whips were fed into the planting machines which cut them into short lengths as they planted them. We were also able to study the special header that Fred was developing for the Claas Jaguar forage harvester. The visit concluded with a field walk through crops at varying ages and stages. It was explained that it is an exceptionally valuable crop for the reclaimed gravel land of the Trent valley, although it grew faster stations but those chips were being due to change in that Drax is planning to on better land.
