3.1 TRACTOR DRAWN LEVELLER

 

Leveller

 Features

 The leveler consists of frame, 3-point linkage, cutting or scraping blade, and thick curved sheet closed from sides to form a bucket. The scraping blade is made from medium carbon steel or low alloy steel, hardened and tempered to about 42 HRC. The blade is joined to the curved sheet with fasteners and can be replaced after being worn out or becoming dull. The working depth of the implement is controlled by hydraulic system of the tractor.

3.2 LASER GUIDED LAND LEVELLER

 

 

Features: 

The laser land leveler consists of a laser transmitter, a laser receiver, an electrical control panel, a twin solenoid hydraulic control valve, two wheels and a leveling bucket. The laser transmitter transmits a laser beam, which is intercepted by the laser receiver mounted on the leveling bucket. The control panel mounted on the tractor interprets the signal from the receiver and opens or closes the hydraulic control valve, which raises or lowers the bucket. Some laser transmitters have the ability to operate over graded slopes ranging from 0.01% to 15% and apply dual controlled slope in the field. The leveling bucket can be either 3-point linkage mounted or pulled by the tractors drawbar. Bucket dimensions, number of wheels and capacity will vary according to the available power source and field conditions.

3.3 SUB-SOILER

 

Features:

 

It consists of beam made of high carbon steel, beam supports which are flanged at upper and lower edges for rigidity, hollow steel adaptor welded to the bottom end of the beam to accommodates share base having square section, share plate made from high carbon steel and shank drilled and counter bored for set board which secures the base in the adaptor. Share plate is made from high carbon steel, hardened and tempered to suitable hardness. Two symmetrically located bolt holes allow reversibility of share. The working depth of the sub-soiler is controlled by hydraulic system and linkage of tractor.

 

Specifications:

 

Length (mm)                                              :     600

Width (mm)                                               :      490

Height (mm)

   :      1325

Maximum working depth (mm)

   :      535

Weight (kg)

   :      62

Power requirement(hp/kW)

   :      55/41.25 and above

 

 

Uses:

 

It is used to break hardpan of the soil, loosening of the soil and helps the water to seep into the soil for improving drainage. A mole ball can be attached to create a small tunnel in the soil, which serves as drainage channel for water.
