The invention comprising a counter-rotating cutting device used for harvesting plant material in a field setting. Said cutting device having two overlayed cutting elements. Said device being attachable to a moving tractor device. The invention further providing individual shears attachable to each of said two cutting elements wherein each individual shear protrudes outward and capable of flexibly bending upward and downward in along the vertical plane.

A cutting apparatus for a header of an agricultural harvester includes a first wheel and a second wheel. A drive source is configured to selectively drive the first wheel in a clockwise direction or an anticlockwise direction. A knife carrier, including a loop having a running side and a knife-carrying side, is tensioned around the first and second wheels for transmitting torque from the drive source to rotate the wheels and the knife carrier. A plurality of knives cut crop mounted to the knife-carrying surface of the knife carrier. A sensor monitors operation of the knives.

This disclosure describes a cutting unit for cutting sphagnum moss. The unit comprises a first pair of substantially parallel blades, laid out substantially according to a first orientation, and spaced apart from about 2 cm to about 30 cm and a second pair of blades, substantially parallel, laid out substantially in a second orientation, and spaced apart from about 40 cm to about 400 cm. The blades of the first pair and second pair being positioned and configured to cut said sphagnum moss.

This disclosure describes a method of collection of sphagnum moss comprising a motorized cutting and collection of at least a portion of the sphagnum moss. The cutting is performed in a direction substantially parallel to the ground and in a direction substantially vertical to the ground, while leaving the sphagnum moss anchored to the ground.

This disclosure describes methods for collecting sphagnum moss. The methods comprise, for example, the motorized cutting and the collection of at least a portion of the sphagnum moss, in which the cutting is carried out at least in a direction substantially parallel to the ground. The disclosure also describes sphagnum moss cutting units and systems for harvesting sphagnum moss.

Vegetation cutting apparatuses may include a wheeled apparatus frame. A cutting assembly may be carried by the wheeled apparatus frame. The cutting assembly may include an elongated chain support member having a chain support member edge. An elongated debris removal slot may extend into the chain support member from the chain support member edge. A cutting chain may be configured to traverse the chain support member edge of the chain support member. An engine may drivingly engage the cutting chain.
