Apparatus (10) for assisting the exchange of blades on a mowing member of a mower having a mowing disk, a blade carrier and at least one blade mounted on the blade carrier via a pin connected to the blade carrier and extends through a recess in the mowing disk, a lever device (11) having at one end an actuating handle (14) actuatable by hand, and has at a second end at least one bending-open body (15, 16), the blade carrier and the mowing disk being able to be displaced such that the pin connected to the blade carrier can be moved out of the recess, a support device (12) mounted in an articulated manner on the lever device (11) and supported on the mowing disk during a bending-open process, and at least one spring element (13) assists the bending-open process via the at least one bending-open body (15, 16).

A blade replacement tool for use in replacing a combine cutting saw knife. The blade replacement tool includes a cable that is operatively connected to a connection link that is used for transferring pulling force to a connected combine cutting saw knife. A pull handle is fastened to the cable. The pull handle receives a pulling force that is transferred via the cable and via the connection link to a connected combine cutting saw knife. The cable is strong, thin and flexible. The pull handle is at least two feet (2 ft.) long. The connection link includes an attachment bracket having first and second apertures for attaching to a cutting saw knife (sickle) via mating apertures in a cutting saw knife (sickle).

A device constructed of a material strong enough to withstand the torque of a typical air wrench or breaker bar used by a lawn mower repair shop or a homeowner. The device must secure two lawn mower blades together in order to bind the blades. The device captures the opposing torque of both blades to cause a restriction in the blades ability to spin freely. To provide economics for manufacturing, one size should fit most blades and the device should require a limited quantity of materials and fabrication.

A tool for mounting a chopping knife to a chopping drum. The tool includes a clamping mechanism for releasably fixing the tool in an auxiliary bore of the chopping drum, a frame, an adjusting element, and a positioning element. The clamping mechanism is reversibly adjustable from a basic state, in which the clamping mechanism is unclamped, to a clamping state, in which the clamping mechanism is clamped. The adjusting element is reversibly displaceable relative to the clamping mechanism and/or the frame in a displacement direction along a displacement axis. The adjusting element reversibly adjusts the clamping mechanism from the basic state to the tensioned state. The positioning device positions the chopping knife on the chopping drum.
