Stearman Patent - Cutting Apparatus
This invention relates generally to a cutting apparatus for mowing machines.
In the past, operators of mowing machines have had many difficulties with conventional sickle bars in that they have gummed up easily. This gumming up, caused by the hardening of plant juices and dirt accumulating on the sickle bar, greatly increases friction and often makes the mowing machine very difficult to operate. Frequently this gummed up material must be removed necessitating a tedious scraping or soaking operation since normal, periodic lubrication is not adequate to prevent this gumming up.
In general, it is an object of our invention to provide an improved cutting apparatus which will prevent gumming of the sickle bar due to accumulation of dirt and plant juices and other foreign material on the sickle bar. Another object of this invention is to provide an improved device of this kind which will make the mowing machine easier to operate and at the same time prolong the life of the sickle bar.
