DRYLAND WEEDER (Peg type):

Drylandweeder

The dry land weeder (peg type) is one of the useful manually operated weeders for operation between the crop rows. It consists of a roller, which has two mild steel discs joined by mild steel rods. The axle passes through the centre of discs and is mounted on the two arms, which also constitutes the frame. The small diamonds shaped pegs are welded on the rods in a staggered fashion. The complete roller assembly is made of mild steel. The V-shaped blade follows the roller assembly and is mounted on the arms. The blade is fabricated from medium carbon steel and forged to shape. The cutting edges are hardened to 40-45 HRC. The height of the blade can be adjusted according to the working depth. The arms are joined to the handle assembly, which is made from thin walled pipes. The height of the handle can also be adjusted according to the operator. For operation the weeder is repeatedly pushed and pulled in between the crop rows in the standing position. The diamonds shaped pegs penetrate into the soil and the rolling action pulverize the soil. The blade in the push mode penetrates into the soil and cuts or uproots the weeds.

Uses: The weeder is used for removing weeds in vegetable gardens, basins of orchard trees and vineyard plantations. It is also used for breaking the soil crust and creation of soil mulch.

 

GARDEN RAKE:

KARJAT HOE:

KarjatHoe

The karjat hoe is a manually operated long handled weeding tool used for operation in between the row crops. The tool is similar to the hand cultivator but differs in the design and shape of the blade. The karjat hoe consists of three V -shape blades joined to the ferrule with three staggered tines/anns. The staggered formation of tines aids in easy handling of the soil during weeding operation. The blades are made from medium carbon steel and hardened to 40-“45 HRC. The tines/ anns and ferrule are made from mild steel. The handle is made from good quality wood or bamboo, which is firmly secured in the ferrule. The karjat hoe is operated in the standing posture by pulling action towards the operator. The pulling action causes penetration of the blades into the soil, which uproot the weeds. The shape of the blades creates small ridges and furrows, which help in water conservation.

Uses: The karjat hoe is used for weeding and interculture in row crops in vegetable gardens, flower crops and nurseries.

 

KHURPI:

Khurpi

The khurpi also known as a hand hoe is most commonly used hand tool for weeding. The tool is used in squatting position. The khurpi consists of a sharp, straight-edged metallic blade with a tang embedded into a wooden handle. The blade and a tang are forged in single piece to a shape from medium or high carbon steel. In some cases alloy steel (nickel, chromium or molybdenum or manganese) is also used for the fabrication of blade. The cutting edge is hardened and sharpened. The tang is joined to the wooden handle with the help of rivets. The shape and design of the khurpi are region or location specific depending upon the soil and cultural practices. For operation the khurpi is held in one hand and pushed into the soil for removal of weeds or unwanted plants. The cutting or uprooting of the weed or undesired plant takes place due to shear and impact action of the blade of the khurpi.

Uses: The khurpi is used for removing weeds and unwanted plants from the crop. The tool is also used for breaking the surface layer, aeration and mulching of the soil.

 

MATTOCK:

MATTOCK

The self propelled weeder consists of a box section chassis, 3-hp petrol -start- kerosene run engine, transmission system, drive wheels, tool mounting bar of 70 x 70 mm size. The engine, gearbox and tool mounting bar are fixed to main chassis. The engine is mounted on front side of the chassis on proper foundation. The gearbox with transmission system is mounted in the middle of chassis. Two steel lugged drive wheels of 500 mm diameter and 110 mm width are mounted on both ends of hexagonal shaft connected to transmission box. The wheel tread (spacing between two wheels) can be adjusted from 400 to 650 mm to suit the row-to-row spacing of different crops. The V -shaped weeding sweeps of 150 and 200 mm size are fitted on tynes. These tynes are mounted on the tool bar with clamps. The tynes are raised or lowered for adjusting the depth of operation and locked in position by the clamp. The spacing between sweeps is easily adjusted by sliding the tynes on tool mounting bar to suit the crop row spacing. Power from engine is transmitted to gearbox through V –belt and pulleys. Inside the transmission box power is transmitted through chain and sprockets to two hexagonal drive shafts/ axles. A lever operated clutch! idler pulley is used for tightening / loosening of V -belt, transmitting the power from engine to transmission box. For operation, the tynes are adjusted to the raised position so they do not dig into the ground and the weeder is transported to the field. The tynes are adjusted according to the row spacing of the crop and depth of operation.
