The spade is courtesy of Ian Adams of Glenbranter Forest Office who has collected a considerable amount of old forestry tools.

Ian is holding onto a manufactured Glendaruel Spade used for planting young trees into forest ploughing in the 1960s. At that time the plough ribbons produced by the single furrow Cuthbertson ploughs were very deep getting on for 10 -12 inches thick. The only way to enable a small tree to be planted with its roots close to the vegetation layer sandwich under the plough ribbon was to cut out a block of peat from the top of the ribbon and then in the recess place the tree in another cut that extended down towards the vegetation layer. This operation entailed the use of a well sharpened garden space to make sometimes three cuts to remove the peat block (called a step) and then another cut to open up the recess to take the young tree which was then well firmed in by the careful thump of the booted foot. The Glendaruel spade reduced the cutting actions to at most two and speeded up the job.

The writer recalls visiting Glendaruel Forest in the mid 1960s and seeing the spade being used. It worked well on the soft friable peats of which there seemed to be large areas but much less well so on the tough stringy peats. The ordinary large garden spade had been modified locally at that time but as can be seen here in the attached PDF the design was taken up by Bulldog tool manufacturers. The label appears to read ‘Bulldog Made in England 2’. This spade of course fell into disuse with the advent of a peat step cutter fitted onto the Cuthberson plough.

Any information on and stories about this spade and its invention would be very welcome.

This spade was invented by my father, Tony Polwart, when he was Head Forester at Glendaruel from 1959 until 1967. I believe the first prototype was produced at the Glen Branter workshop. Comment left on 01 December 2019 at 14:27 by Tim Polwart
The theory behind the design was excellent but the spade was quite heavy to use if you were used to planting with the much lighter garden spades. It was very tiring to use with one hand and hold the plants in the other. A way round this was to pair up and one person cut the notches and the other planted the trees. The notcher also carried plants. At break times you swapped round. If the planter caught up, or the notcher got too far ahead, he would go for more plants and place them where they were handier for using. Comment left on 01 December 2019 at 23:05 by Andy MacNicol
The Glenbranter workshop, Jimmy Fleming in particular, came up with quite a few ideas which were put into practice. The Fleming carriage for use on skyline winches, the JF clamp was easier to fit instead of Bulldog grips for clamping wire ropes. I believe the self-release hook was also a product of the workshop but I'm not 100% sure about that. Comment left on 01 December 2019 at 23:10 by Andy MacNicol
