  Forage harvester recutter screen - Patent 4505434
A forage harvester having an axially transverse generally cylindrical cutterhead mounted for rotation in a housing.
In a forage harvester as set forth in claim 1 wherein said first and second series of apertures are slot-like in shape with elongated generally parallel opposite sides.
This invention relates to forage harvesters and, more particularly, to a removable recutter screen mounted in the cutterhead housing adjacent to and rearwardly of the generally cylindrical cutterhead to further reduce crop particle size before it is discharged by urging the crop material into engagement with shearing edges of apertures in the screen.

 Cost of Silage Harvest and Transport Systems
For option 3, for a forage harvester with a two-row head, hitching and unhitching would be acceptable from a time perspective, but for a self-propelled harvester with a six-row head this would result in too much downtime for the expensive forage harvester and reduce field efficiency to about 50%.
The number of forage wagons required to transport silage from the field to the field edge depends on crop yield and moisture content, the forage crop head used, and its associated rate of operation (ha/h or ac/h), and the hourly capacity of each wagon.
Forage harvesters are expensive to operate, costing between $55 and $121/h and $67 to $106/ha ($27 to $43/ac) (including labor) at 70% field efficiency.

 Forage harvester - Wikipedia, the free encyclopedia
A Forage Harvester (also known as a Silage Harvester) is a farm implement that creates silage.
Forage harvesters can be implements attached to a tractor, or they can be self-propelled units.
In either configuration, they have a blower that blows the silage out a chute at the rear of the harvester into a wagon that is connected to the harvester.

 Forage harvester knife and mounting apparatus - Patent 5779167
The present invention relates generally to forage harvesters and more particularly to a new knife design and associated knife mounting apparatus for a harvester cutterhead unit having a segmented knife configuration.
A typical forage harvester operates in a field to process windrowed or standing forage crop and includes a mobile base unit that is either self propelled or pulled by a tractor.
In segmented knife cutterheads, as in all forage harvester cutterheads, the rake angle of the knives is an important design consideration, i.e., the acute angle of the knife relative to crop material being fed across the shear bar.

 Cut crop processing mechanism for a forage harvester incorporating a pivotable auger - US Patent 6125617   (Site not responding. Last check: 2007-10-16)
The harvester of claim 10, wherein the discharge mechanism comprises a discharge blower defining an intake opening, and further comprising means for providing passage of cut crop material from the auger housing outlet to the discharge blower intake opening when the auger and auger housing are in both the first position and the second position.
It is a further object of the invention to provide a forage harvester which incorporates components which operate satisfactorily to cut and discharge crop material either when a roller mill section is positioned in the cut crop material flow path or removed from the cut crop material flow path.
While the drawings illustrate harvester 20 as discharging into a towable vehicle such as forage box 24, it should be understood that harvester 20 may be used to discharge cut crop material into any other collection receptacle, such as into the box of a truck or any other arrangement as is known in the art.

 NIOSH FACE Program: Massachusetts Case Report 00MA014 | CDC/NIOSH
The machinery involved in the incident was a corn chopper attachment (figure 1) for a self-propelled forage harvester.
The corn chopper head was used for cutting corn stocks during harvesting and was attached to the front of a forage harvester.
The victim had positioned the corn chopper head, which was unattached from the forage harvester, approximately 12 feet inside the garage by the overhead door entryway.

 The Application Of Harvester-Mounted Forage Yield Sensing Devices
A precision-chop forage harvester (JF 850) was instrumented to monitor: (i) the opening of the feed rollers; and (ii) the force exerted by the chopped forage in the chute (Fig.
Grass is delivered from the forage harvester by the impelling force of the cylinder, which throws and blows the grass through the delivery chute to the trailer.
In a forage harvesting situation the crop dry matter may change significantly as the crop is being harvested.

 The Application Of Harvester-Mounted Forage Yield Sensing Devices
The opportunities to assess grass flowing through a forage harvester are less than those available to measure the quantity of grain flowing through a combine harvester.
However, harvesting grass from perennial crops is likely to cause greater difficulties, as the delivery of grass from a pre-cut and picked-up swath is likely to be more uneven than from direct-cut maize or whole-crop silage.
All trailer loads of harvested grass were weighed using a conventional weighbridge and sampled for grass dry matter content.

 Dáil Éireann - Volume 304 - 08 March, 1978 - Written Answers. - Forage Harvester Aid Scheme.
Bruton asked the Minister for Agriculture why he proposes to end the grants scheme operating through the county committees of agriculture since 1964 for the purchase of forage harvesters by contractors and groups of farmers in all parts of the country; and the amount of money paid out under this scheme last year.
Its continued operation is not, therefore, considered justified, particularly in the light of the introduction in 1977 of the EEC scheme of grants for farm groups in disadvantaged areas purchasing machinery for fodder production.
The forage harvester scheme has been operated on a year-to-year basis through the committees of agriculture, the terms being notified to them in the [1122] month of March or April each year.

 To Buy or Not To Buy
In the case of a forage harvester, Buckmaster said, there is a wide range of factors that bears on PWD: today’s weather, yesterday’s weather and whether you mowed yesterday, for example.
With this harvester example, the producer could work fewer days (10.5), fewer hours/day (7.5), or even finish the harvest in the 14-day window in a poorer year where the PWD is as low as 30%.
For the harvester in the example above, the 83 tons of silage per hour would require a forage harvester with at least 83 x 4, or 330 horsepower.
