1,157,121. Mowing-machines. INTERNATIONAL HARVESTER CO. 17 Aug., 1966 [3 Sept., 1965], No. 36801/66. Heading A1F. A clamping member 40 which holds the knives 30 against stationary cutters 24 is adjustable to compensate for wear. The adjustment is effected by a pair of screws 61 which cause the member to rock about axis X while tightly held by nuts 54 on a pair of fixing bolts 12. The member has a pair of fingers 45 which engage a pair of adjacent knives and are joined by a crossrib (not shown). In a modification (Figs. 3 and 4, not shown), the knives are accommodated in recesses in stationary guards and the clamping member has a single knife-engaging finger.
