Off set Miller Attachment - Milled Peat
Type I – used with L.H.T. Tractor - Type II
This attachment is used to form a bevel on the edges of milled peat fields, to assist surface drainage.
The attachment is a miller drum, projecting from the rear of the tractor unit on a casing arm which is pivoted at a central position on the rear of the tractor main frame, and is extended to carry a ballast weight. The drive is taken from the tractor P.T.O. Shaft, through a bevel gearbox which forms the pivot assembly of the arm and a universally jointed propellor shaft extends to the actual milling drum.
The milling drum is set backwards as it extends from the tractor so that the spoil is thrown back towards the centre of the milled peat field, where it can be harvested.
A supporting trolley fixed to a projecting bracket at the centre of the tractor track and supported on a roller behind the drum, carries the drum arm on an adjustable suspension. The trolley, complete with extension arm and drum can be lifted by a winch rope passing over a mast frame mounted on the tractor.
For bogs in early development a bladed drum is used, while a pin drum is used on production bogs.
