8.1 SELF-PROPELLED VERTICAL CONVEYOR REAPER

Features:

 

It is an engine operated, walk behind type harvester suitable for harvesting and windrowing cereals and oilseed crops. The reaper consists of engine, power transmission box, pneumatic wheels, cutter bar, crop row dividers, conveyor belts with lugs, star wheels, operating controls and a sturdy frame. The engine power is transmitted to cutter bar and conveyor belts through belt pulleys. During forward motion of the reaper, crop row dividers divide the crop, which come in contact with cutter bar, where shearing of crop stems takes place. The cut crop is conveyed to one side of the machine by the conveyor belt fitted with lugs and is windrowed in the field. The crop is bundled manually and transported to threshing yard. There are no shattering losses due to vertical conveying of the crop.

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.

8.5 SHRUB MASTER

stuble shaver

 

 

 

 

 

 

 

Features:

 

It consists of cutting blades (swinging flails) fixed to the rotating bar, gear box for transmission of power at right angle, universal joints with telescopic shaft to connect the tractor PTO and gearbox, adjustable side skids for controlling cutting height of shrubs or grass, safety guard and hitching frame. It is operated by tractor PTO. The bar having cutting blades fixed at the ends is mounted on the gearbox shaft. Thus, the vertical shaft of the gearbox provides rotary motion to the bar. The cutting blades mounted on the bar swing open to the cutting position due to centrifugal force as the bar rotates in the horizontal plane. The cutting takes place purely through impact and flails need not be sharp-edged. The blades are made of medium carbon steel or alloy steel and hardened.

 

Specification:

 

Overall dimension(mm) : 200016601000

No's of Blades : 2

Cutting width : 1600 mm

Total weight : 350 kg

Power drive : PTO operated

Power Requirement (hp/kW) : 25/17.5 or above.

 

Uses:

 

It is used for the clearance of shrubs, monsoon growth in forests, fields, verges, helipads and general clearance of grasses in fields.

 

Cost (Rs) : 40,000
