摘要： The adjustment between the stub guards of a sickle knife arrangement of a crop cutting apparatus is improved by the provision of an adjustment plate which is positioned between the upper stub guard and the support bar. The upper and lower stub guards are clamped onto the support bar by carriage bolts with the lower stub guard engaging against the under surface of the support bar and the upper stub guard engaging against the upper surface of the adjustment plate. The spacing and orientation of the adjustment plate relative to the support bar is adjusted by the three set screws which are threaded into the adjustment plate and engaged against the upper surface of the support bar. The adjustment technique is simple, requires few parts and avoids the necessity for shims.

摘要： In a sickle cutting system including a plurality of guard fingers at spaced positions across a cutter bar across which a reciprocating sickle knife passes, each guard finger has a forwardly projecting tip portion in front of a ledger surface and a rearwardly projecting tang portion connected to a rear end of the tip portion and extending therefrom over the ledger surface to a rear edge of the tang portion located over the blade. The lower surface of the tang portion includes a first portion adjacent the tip portion which is generally parallel to the ledger surface and a second portion adjacent the rear edge which is inclined at an angle away from the ledger surface. The width of the tang portion across the rear of the tang portion is equal to or greater than 1.5 inches.

摘要： Decisive modifications are proposed to a cutting system reducing cutting losses and having a floating disk, in order to improve the efficiency of the system. The lower finger (1) cuts at the lower level and has a tip pointing upwards to prevent the finger from entering the ground; weeds passing past the lower finger pass over the upper finger (3), the accumulation of branches between the fingers being thus prevented. The upper finger (3) has a guard (4) that prevents grains from dropping out of the cutting platform, and the guard is also used to mount two bearings which act to orient the cutter bar (2).
