Abstract

1326900 Mowers MASSEY-FERGUSONPERKINS Ltd 13 Nov 1970 [5 Dec 1969] 59412/69 Heading A1F A mowing-machine rotor 10 comprises a circular centre portion 11 and an oval flange portion 12, the latter carrying cutting blades 13 by means of set-screws 20 cooperating with nuts 21 welded to the flange portion 12. Each nut is elongated on its leading side to prevent excessive wear, and the head of the set-screw 20 is protected by a shroud member 22 having flanges 23 welded to the flange portion 12, allowing the cutting blade 13 to be inserted in the resulting slot 24. The shroud member 22 is provided with a lip 25 which lessens the tendency of the blade 13 to be deflected upwardly, and a deflector plate 26 is welded to the flange portion 12 such that the upper end of the plate 26 coincides with the leading edge of the shroud member 22. A typical output of known drive means is in the form of a rotatable flanged member 17 to which the rotor is secured by means of set-screws 18. To protect the set-screws 18 and to prevent out crop winding around them, a protector cap 27 can be welded to the top of the centre portion 11. Several of these rotors can be used in line, when the alternate oval rotors are rationally staggered by 90‹. In other embodiments, the rotor 10 may be of circular shape, and the deflector plate 26 and lip 25 can be omitted.
