Claim 5

A flail type rotor assembly as claimed in claim 1 in which said blade comprises a length of high carbon steel rod stock bent to provide said shank and said side arm including said extension, and said extension being flattened with respect to its longitudinal axis to provide said cutting edge.

Claim 6

A flail type rotor assembly as claimed in claim 1 in which said confining means is a clinch nut.

Claim 7

A flail type rotor assembly as claimed in claim 1 in which the axis of said extension is disposed at from 30* to 45* to the axis of said rotor drum. 7 A flail type rotor assembly as claimed in claim 1 having a plurality of hingedly mounted paddles located on the surface of said drum.

Claim 8

A flail type rotor assembly as claimed in claim 1 in which said blade mounts are arranged in four rows, a, b, c, d, spaced from each other by 90* with rows a and b 180* apart, and rows c and d 180* apart, the axial location of the mounts of rows a and b being identical to each other and the axial location of the mounts of rows c and d being identical to each other and being midway between the axial location of the mounts of rows a and b.

Claim 9

A flail type rotor assembly as claimed in claim 8 in which said extension is provided with two oppositely disposed cutting edges so that one of said cutting edges will be a forwardly facing cutting edge irrespective of the orientation of said blade within said blade mount, the blades associated with the mounts of rows a and b respectively being oppositely oriented to each other, and the blades associated with the mounts c and d respectively being oppositely oriented to each other.

Claim 10

A flail type rotor assembly for a mowing machine comprising a rotor drum, a plurality of loop type blade mounts extending from the surface thereof and having their axes parallel to the axis of said drum, a plurality of blades, each comprising a length of high carbon steel rod stock bent to provide a shank and a single side arm, said said arm including a diagonally disposed extension, said extension being flattened with respect to its longitudinal axis to provide a cutting edge, said shank being received within one of said loop type blade mounts with the free end thereof extending beyond same, said free end being threaded, and means engaging said threaded end and loosely confining said shank portion within said blade mount, said blade being oriented within said blade mount so that said cutting edge faces in the forwardly direction with respect to the rotation of said drum.

Claim 11

A flail type rotor assembly for a mowing machine comprising a rotor drum, a plurality of loop type blade mounts extending from the surface thereof and having their axes parallel to the axis of said drum, a plurality of blades, each comprising a length of high carbon steel rod stock bent to provide a shank and a single side arm, said said arm including a diagonally disposed extension, said extension being flattened with respect to its longitudinal axis to provide a cutting edge, said shank being received within one of said loop type blade mounts with the free end thereof extending beyond same, said free end being threaded, and means engaging said threaded end and loosely confining said shank portion within said blade mount, said blade being oriented within said blade mount so that said cutting edge faces in the forwardly direction with respect to the rotation of said drum.

Claim 12

A flail type rotor assembly for a mowing machine comprising a rotor drum, a plurality of links hingedly mounted on the surface of said rotor drum, each link having at its outer end a loop type blade mount, a plurality of blades, each comprising a length of high carbon steel rod stock bent to provide a shank and a single side arm, said side arm including a diagonally disposed extension being flattened with respect to its longitudinal axis to provide a cutting edge, said shank being received within one of said loop type blade mounts with the free end thereof extending beyond same, said free end being threaded, and nut means engaging said threaded end and loosely confining said shank portIon within said blade mount, said blade being oriented within said blade mount so that said cutting edge faces in the forwardly direction with respect to the rotation of said drum.

Claim 13

A flail type rotor assembly for a mowing machine comprising a rotor drum, a plurality of links hingedly mounted on the surface of said rotor drum, each link having at its outer end a loop type blade mount, a plurality of blades, each comprising a length of high carbon steel rod stock bent to provide a shank and a single side arm, said side arm including a diagonally disposed extension being flattened with respect to its longitudinal axis to provide a cutting edge, said shank being received within one of said loop type blade mounts with the free end thereof extending beyond same, said free end being threaded, and nut means engaging said threaded end and loosely confining said shank portIon within said blade mount, said blade being oriented within said blade mount so that said cutting edge faces in the forwardly direction with respect to the rotation of said drum.

Claim 14

A blade for a flail type mower comprising a blank of rod stock of high carbon steel bent so as to provide three sections, the axes of which lie in a substantially common plane, the first and second sections being disposed substantially perpendicular to each other to provide a shank portion and a connecting portion, and the third section being disposed at an obtuse angle to the second section, the outer portion of said third section having two cutting edges facing in opposite directions and away from said substantially common plane, said blade having been heat treated after said edge formation and said bending, the free end of said first section being threaded.

Claim 15

A blade for a flail type mower comprising a blank of rod stock of high carbon steel bent so as to provide three sections, the axes of which lie in a substantially common plane, the first and second sections being disposed substantially perpendicular to each other to provide a shank portion and a connecting portion, and the third section being disposed at an obtuse angle to the second section, the outer portion of said third section having two cutting edges facing in opposite directions and away from said substantially common plane, said blade having been heat treated after said edge formation and said bending, the free end of said first section being threaded.
