Double drum winch set up Glentress Forest

This is a more distant view of the cable crane and tractor and a closer view is in the attached PDF. The third image is that of the men in the previous image on this website Record No 4164.
The cable crane unit FC62893 is a little unusual as the tower indicates manufacture and assembly by Forestry Commission Chapelhall Workshops but initially the tractor units they used were Ferguson then British Leyland. The other unusual feature is the actual set up of the cables, no skyline cable drum on the tractor wheel but it could all be in the process of being dismantled to move another site.
The tower anchor system was normally two separate ropes directly onto the tower to allow for setting up of accurate opposing forces to the haul in rope and often offset haul back rope. Here they have no trees to anchor onto and will have had to use ground anchors quite some distance back down the slope. They have used a single tower anchor main rope dividing into two short strops to fit to the two anchor rings on the tower. A second tower anchor rope is hanging loose on the system and may also have been attached to ground anchors in the same area as the first.
This could of course just be a high lead set up but the large volume of timber at roadside would seem to indicate a longer haul distance more indicative of a skyline.
Does anyone know the purpose of the light coloured box like structure at the rear of the tractor just below the bottom of the tower?
