A method of securing a blade to an apparatus for cutting vegetation, wherein the apparatus includes a first and a second blade contacting structure. The method includes providing an elongated blade that is configured and arranged to be relatively flexible; and positioning the elongated blade between the first blade contacting structure and the second blade contacting structure such that the first blade contacting structure makes contact with a first surface of the elongated blade and the second blade contacting structure makes contact with a second surface of the elongated blade. The positioning step results in a plurality of bending forces being applied to the first and second surfaces of the elongated blade via the first and second blade contacting structures, thereby bending the elongated blade, and whereby the bending forces secure the elongated blade to the apparatus for cutting vegetation.

A mower for turf or lawn includes a frame for use on a tractor, or to form a structure of a trailer, and a plurality of cutting units, at least six, generally disposed side by side, each cutting unit including at least one roller for rolling on the ground. The mower includes lift means linking the cutting units to the frame and configured for articulating the cutting units between a mowing position and a non-mowing position. In the mowing position, the lift means are configured for pressing the cutting units against the ground in order to distribute, at least partially, the mower's weight on the ground via the rollers of the cutting units. The mower includes lateral articulated beams linking the cutting units. The beams are foldable inwardly and forwardly.

A chopper system and method for cutting crop material with a rotating first drum having first blades and a counter-rotating second drums having second blades. Blade pairs with one first blade and one second blade contact one another and cut the crop material. The blades of each blade pair contact one another for at least ten degrees of rotation. The blades can have beveled cutting edges, and the blade pairs can make bevel to bevel contact. The initial contact of the blade pairs during each rotation can form a swipe angle of 15 degrees or less. The initial contact of the blade pairs during each rotation can have the acute end of the first blade contact the second blade near the middle of the beveled edge. During each rotation, the acute end of the second blade can contact the back of the first blade.

Differential speed stalk rolls mountable to a row unit of a row crop head. A first stalk roll body has an outer peripheral speed less than the outer peripheral speed of a second stalk roll body in lateral spaced relation. The stalk roll bodies may have modular and interchangeable body segments of different configurations.

The stalk eliminator chops stalks, uproots stalks, and re-chops stalks. The apparatus includes a front stalk chopper on a rotating cylinder with angularly attached blades. A plow tool attaches to the apparatus and provides a subsoiler wing behind and under the front stalk chopper. A rear stalk chopper on a rotating cylinder with angularly attached blades follows the plow tool.

Methods of using a mower are provided. The methods include providing a mower having a plurality of cutting heads, a first driven wheel supported at a first end of the plurality of cutting heads, and a second driven wheel supported at a second end of the length of the plurality of cutting heads. In some methods, each cutting head of the plurality of cutting heads is at least one of pivotably connected or translatably connected to at least one other cutting head of the plurality of cutting heads. Some methods include driving the first driven wheel such that the mower pivots about the second driven wheel.
