| Abstract | 'A rice panicle harvester prototype has been developed by
incorporating a number of modification in Kubota AR - 120 reaper.
The prototype is equipped with a reel for lifting and guiding the
paddy plants, cutter bar for cutting the plant stalks, rotor for
holding the incoming plants and a temporary collecting tray.
The prototype is intended to harvest only the panicles. The
h eight of the knives at 45 c m from the ground with provision for
adjustment up to 30 cm. Reel was set at 45 cm horizontally and 42 cm
vertically, rotor was set at 15 cm vertically from the tip of the
knives
Tl1e prototype can cut plants evenly at the desired height.
Average the stubble height ranged from 40-54 cm. 'The cutting
efficiency varied from 96 up to QR %. Length o f c 1Jt ranged from 30 -
40 c m with average 15 cm. The average of grain - straw ratio is 0.75
as compared to manual harvesting of 0. 54. The average shattering
loss ranged from 2 - 12 % at 15.9 % grain moisture content. |
