Article in Journal of the Forestry Commission 1962 - Ledmore Lining Out Plough
This article by Sandy Rose, Head Forester at Ledmore Nursery, explains in detail the design and operation of the new Mark III lining out plough. The full article is reproduced in the PDF which can be accessed in the link below the text. This was just one of the machines and mechanised tools designed by Sandy at Ledmore and expertly built at the nearby Red Gorten blacksmith engineers.
THE LEDMORE MOUNTED LINING-OUT PLOUGH MARK III
By
A. ROSE
Forester, East Scotland
Introduction
The plough is designed to fill and level one lining-out treach and to cut and prepare the next simultaneously. An important feature of its operation is that it fills a trench in two stages, first turning and compacting well tilthed soil against the seedling roots and then turning in and levelling the bulk of the soil.
The Mark III plough is a much-improved version built for mounting on a wheeled tractor. The plough has been simplified and made more compact (it now measures only 6 ft. by 4 ft. length and width overall) and the depth control has been completely re-arranged so that the plough, which Is tested and preŽset when made, largely controls its own depth of working.
The plough is not upset by soil conditions except where there are a lot of
large buried stones, and it will operate on gentle slopes. Working with a well organised squad and capable supervision, 10,000 seedlings per member of the squad (including tractor driver and supervisor) can be lined-out each working day at costs considerably lower than corresponding hand-lining costs.
The plough has been in use at Ledmore for some time and recently in other nurseries. From evidence at Ledmore the quality of plant produced is as good as by hand-lining and the percentage survival of plough-lined seedlings is at least as high as that of hand-lined seedlings.
