Tohr 987S Harvester in Bennachie Forest

Tom does not remember this machine but believes it was on trial as a thinning machine at Bennachie for a short period. It was about this time that a variety of harvesting machines were trialled for thinning in the Forestry Commission areas of Aberdeenshire due to the increasing difficulties in retaining felling contractors due to the rise of the better paid jobs in the oil, gas and related industries.
The PDF shows more views of the felling head which looks large in comparison with the base machine. Note the Jonsered crane assembly with a short extension boom housed in the end segment. The felling head appears to have had a stump spraying facility for covering the felled stump with a urea water mixture as a protection against a butt rot fungus.
Can anyone remember this machine, its origins, the owner and where it was based?
