ABSTRACT:
A ski trail making means, composed of a frame for attachment e.g. behind a snowmobile and to which has been pivotally connected a drag adjustable in vertical direction, following after which is a trail planer with trail making blades side by side, after which follows a cylindrical levelling roll supporting the means. The drag is suspended by linkage arms pivoted to the frame in such manner that it is free to rise upwardly. The trail planer is resiliently attached to the frame. The levelling roll carries projecting trail groove depressor rims. The means of the invention has a light-weight design and is therefore well fit to be towed e.g. with a snowmobile. The means is also advantageous owing to its simplicity.
