Abstract
A knife guard filler finger assembly is provided with a mounting plate, rearwardly opening slots in the mounting plate which are positionable over bolts and beneath the lugs of original equipment fingers, the bolts securing the mounting plate to the cutting platform of a harvester, and fingers which project forwardly of the mounting plate and are located between the original equipment fingers of a harvester cutter platform. When fitted to a cutting platform, the filler fingers are generally positioned between, and at the same level as, the existing knife guard fingers.
Claims9
For use on a grain harvester cutting platform having as original equipment a plurality of knife guard fingers which project forwardly of mounting lugs in spaced relationship with one another, a knife bar having drive means which reciprocally drives it across the cutting platform and knives thereon which co-operate with the knife guard fingers to sever the stalks of a grain harvester crop, and respective nut and bolt assemblies securing the lugs to the cutting platform:
- a filler finger assembly comprising a mounting plate, surfaces defining rearwardly directed and rearwardly open slots on the mounting plate of such size and shape that the mounting plate is positionable over a plurality of said bolts and beneath said lugs to thereby be secured to said cutting platform,
- a plurality of spaced parallel support bars each extending forwardly of the mounting plate and each being between adjacent said slots therein, and a plurality of forwardly projecting fingers carried by respective said support bars.
On a grain harvester cutting platform having as original equipment a plurality of knife guard fingers which project forwardly of mounting lugs in spaced relationship with one another, a knife bar having drive means which reciprocally drives it across the cutting platform and knives thereon which co-operate with the knife guard fingers to sever the stalks of a grain harvester crop, and respective nut and bolt assemblies securing the lugs to the cutting platform, improvements comprising:
- a plurality of filler finger assemblies each comprising a mounting plate, the mounting plates lying end to end across the cutting platform, each mounting plate having surfaces defining a plurality of rearwardly directed and rearwardly open slots which accommodate bolts of said nut and bolt assemblies, the mounting plate being secured thereby to the cutting platform and contiguous with the undersurfaces of a plurality of said mounting lugs,
- a plurality of spaced parallel support bars extending forwardly of each said mounting plate but between the slots thereof, and filler fingers extending forwardly of respective said support bars.
