Claims16
A hitched grooming device comprising:
- a tapered main frame,
- a plurality of staggered angled blades
- at least one straight blade attached to the tapered main frame;
- a second pivot, pivoting around a horizontal axis
- a second pivot actuating means to move the tapered main frame in relation to a towing vehicle so as to horizontally level a trail across its width;
- a compactor frame hingedly attached to a beam by way of hinges;
- the beam being attached to the tapered main frame by way of the second pivot;
- a third pivot rotating so as to allow the compactor to rotate along a compactor's horizontal axis;
- the compactor's horizontal axis being in the same horizontal plane but perpendicular relative to the second pivot's horizontal axis;
- the compactor's horizontal axis preventing the compactor's toe to dig into the trail when the towing vehicle goes down a hill or preventing the compactor's heel to dig into the trail when the towing vehicle goes up a hill.

A hitched grooming device comprising:
- a tapered main frame,
- a plurality of staggered angled blades
- at least one straight blade attached to the tapered main frame;
- a first pivot, along a vertical axis, pivotally connects the front frame to the rear frame and is actuated by at least one first pivot actuating means;
- a second pivot, pivoting around a horizontal axis
- a second pivot actuating means to move the tapered main frame in relation to a towing vehicle so as to horizontally level a trail across its width;
- a compactor frame hingedly attached to a beam by way of hinges;
- the beam being attached to the tapered main frame by way of the second pivot;
- a third pivot rotating so as to allow the compactor to rotate along a compactor's horizontal axis;
- the compactor's horizontal axis being in the same horizontal plane but perpendicular relative to the second pivot's horizontal axis;
- the compactor's horizontal axis preventing the compactor's toe to dig into the trail when the towing vehicle goes down a hill or preventing the compactor's heel to dig into the trail when the towing vehicle goes up a hill.
