Studies on Harvesting Machines (28)

Design and Trial Made of Small Windrower

Abstract

We have reported about our windrowers named E52, E54 and E55 with cutter bar length of 30cm or less which could cover one or two rows of crops.
Recently some extension works to drill wheat, barley and rice by tractor mounted drill seeders were took up into activity, and this tendency urged us, to develop other types of harvesters with which to harvest drilled crops.
From 1959 to 1961, we constructed and tested three types of small windrowers attached to small tractors (2-5PS), cutter bar length of which was 60cm. Two of them, namely HR601 (fig. 4) and HR 604 (fig. 7), gave good results. Many partial mechanisms were also tested in field conditions.
These two were found to be suitable for windrowing 4 rows of drilled/50cm width of broadcast wheat or barley, or 3 rows of transplanted rice. When the width of cutter bar, poor results were obtained. The adaptability of these machines for lodged crops is illustrated in fig. 8.
HR601 has simple mechanism, and several agricultural machinery factories began to commercialize it.
Though HR604 is larger and much complicated than HR601, the former makes it easy for farmers to band. le the windrowed crops manually. Further, the divider board of the harvester can divide lodged crops farely well.
