Abstract
Abstract A spreading device is disclosed which is particularly suitable for use with drum mowers. The spreading device includes a crop divider of a unique shape and configuration which extends in front of the forward mowing direction of the mower and which is positioned between the two mower drums, or between each pair of mower drums in a large scale mower. The crop divider includes two fins extending in an angled relationship with respect to a main body portion thereof forming a Y-shaped configuration when viewed from the top. A pair of feeder chains is connected to each of the drum mowers in the pair for moving the cut crop through the mower and adjacent to the crop divider fins.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
138 words
In a rotary mowing machine including a frame member and at least a pair of rotary mower drums rotatably mounted to said frame member, a spreading device for evenly distributing a mowed crop over a mowed swath comprising: a crop divider for dividing crops to be mowed, said crop divider secured to said frame member at a position between said mower drums and extending forward of said drums in the direction of mowing, said crop divider including an upstanding main body portion having rewardly extending crop channelling fins; said mower drums rotating toward said crop divider in said direction of mowing; and, feeder chain means coupled to each of said mower drums for sweeping said mowed crop toward said crop divider and cooperating with said crop channelling fins for distributing the mowed crop uniformly across the mowed swath.
Claim 2
Dependent Claim
138 words
In a rotary mowing machine including a frame member and at least a pair of rotary mower drums rotatably mounted to said frame member, a spreading device for evenly distributing a mowed crop over a mowed swath comprising: a crop divider for dividing crops to be mowed, said crop divider secured to said frame member at a position between said mower drums and extending forward of said drums in the direction of mowing, said crop divider including an upstanding main body portion having rewardly extending crop channelling fins; said mower drums rotating toward said crop divider in said direction of mowing; and, feeder chain means coupled to each of said mower drums for sweeping said mowed crop toward said crop divider and cooperating with said crop channelling fins for distributing the mowed crop uniformly across the mowed swath.
Claim 3
Dependent Claim
28 words
A rotary mowing machine as in claim 1, wherein: said crop divider includes a curved, sloping front edge with a rounded element secured thereto to prevent crop bunching.
Claim 4
Dependent Claim
207 words
In a rotary mowing machine including a frame member and at least a pair of rotary mower drums rotatably mounted to said frame member, a spreading device for evenly distributing a mowed crop over a mowed swath comprising: a crop divider secured to said frame member at a position between said mower drums and extending forward of said drums in the direction of mowing, said crop divider including a main body portion having a pair of crop channelling fins at the rear of and extending outwardly from the plane of said main body portion, and chain means for sweeping said mowed crop toward said crop divider, said feeder chain means including at least two pairs of feeder chains, each pair of feeder chains coupled to a respective rotary mowing drum, one of the feeder chains in each pair coupled to the respective rotary mower drum at a height substantially the same as that of the bottom edge of said crop channelling fins, and the other of the feeder chains in each pair coupled to the respective rotary mower drum at a position above that of said one of the feeder chains for cooperating with said channelling fins and distributing the mowed crop uniformly across the mowed swath.
Claim 5
Dependent Claim
207 words
In a rotary mowing machine including a frame member and at least a pair of rotary mower drums rotatably mounted to said frame member, a spreading device for evenly distributing a mowed crop over a mowed swath comprising: a crop divider secured to said frame member at a position between said mower drums and extending forward of said drums in the direction of mowing, said crop divider including a main body portion having a pair of crop channelling fins at the rear of and extending outwardly from the plane of said main body portion, and chain means for sweeping said mowed crop toward said crop divider, said feeder chain means including at least two pairs of feeder chains, each pair of feeder chains coupled to a respective rotary mowing drum, one of the feeder chains in each pair coupled to the respective rotary mower drum at a height substantially the same as that of the bottom edge of said crop channelling fins, and the other of the feeder chains in each pair coupled to the respective rotary mower drum at a position above that of said one of the feeder chains for cooperating with said channelling fins and distributing the mowed crop uniformly across the mowed swath.
Claim 6
Dependent Claim
