8.2 TRACTOR MOUNTED VERTICAL CONVEYOR REAPER

 

 

Features:

The machine consists of a 76 mm pitch reciprocating cutter bar assembly, seven crop row dividers, and two vertical conveyor belts fitted with lugs, pressure springs, pulleys and gearbox for the power transmission system. The crop row dividers are fitted in front of the cutter bar assembly and the star wheels are mounted over the crop row dividers. The machine is mounted in front of the tractor and the power to the machine is given from tractor PTO with the help of intermediate shaft running beneath the chassis of the tractor and a coupling shaft. Height of the machine above ground is controlled by tractor hydraulics with the help of pulleys and steel ropes.  After the crop is cut by the cutter bar, it is held in a vertical position and crop is delivered to one side of the machine by lugged belt conveyors and fall on the ground in the form of a windrow perpendicular to the direction of movement of the machine.

8.7 GROUNDNUT DIGGER SHAKER

 

 

Features:

 

It consists of a digging blade of 1200 mm length, an elevator shaker, idlers, driving sprockets, two disc coulters two gauge wheels, fenders and gearbox. The front end of the picker elevator reel is adjusted in accordance with the depth of working of the blade. The angle of the shaker conveyor is 30 degrees with horizontal and has a length of 1270 mm. The digger is operated by a tractor of 35 hp or higher. The PTO through a telescoping shaft supplies power to the gearbox of the machine. It digs the groundnut vines below the pod zone and elevates them by an elevator-picker reel (conveyor) for dropping on the ground. The soil attached to the vines is shaken off in the process and a windrow is formed with the help of deflector rods. The vines are dropped in such a manner that the pods get exposed to the sun for speedy drying.
