1889 Rose Disk Harrow Detail
Date : 1889, 2003
Description : In 1889, Henry Rose appllied for another patent for his line of harrows (number 416,346). This detail drawing shows the cleaner on one disc. This model was a sulky, so the disks were under and behind the seat.
The scraper C is a thin, elastic strip of steel with a beveled scraping edge. It is attached to a movable frame with a screw. The spring attached to a second bar allows the driver to raise and lower the scraper as needed with a treadle.
