3.2 SUB-SOILER

super_subsoilerDSC00354

Features:

it consists of a beam made of high carbon steel, beam supports which are flanged at upper and lower edges for rigidity, hollow still adaptor welded to bottom end of the beam to accommodate the share base, 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. Sub-soiler is used where land is not cultivated from many years. It is used to break the hard pan. It breaks the subsoil. It takes depth up to 60 cm.

 Specification:

Length (mm)                                              :      600

Width (mm)                                               :      490

Height (mm)                                              :      1325

Maximum working depth (mm)      :      535-600

Weight (kg)                                               :      62-125

Power Requirement(hp/kW)                   :       55/41.25, tractor and above

Uses:

It is used to break hard pan of the soil and helps the water to seep in to 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.

Cost (Rs) :   20,000-60,000

Laser Land Leveller3.3 LASER GUIDED LAND LEVELLER

 

 

 

 

 

 

 

Features:

The laser land leveller consists of a laser transmitter, a laser receiver, an electrical control panel, a twin solenoid hydraulic control valve, two wheels and a levelling bucket. The laser transmitter transmits a laser beam, which is intercepted by the laser receiver mounted on the levelling 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 levelling bucket can be either 3-point linkage mounted or pulled by the tractor’s drawbar. Bucket dimensions and capacity will vary according to the available power source and field conditions.

Specifications:

 

Laser Source                                         :      < 5mw 635 nm

Operating diameter                               :      ( Above) 800

Grade Range (%)                                  :      -10 to + dual Axes

Grade accuracy (%)                              :       0.015, 3mm@30m

Remote control type                             :       Full two way communication

Power Requirement (hp/kW)                 :     60/45, tractor & above

Uses  :

It is used for precision levelling o f land in single or both the directions. It can be used for grading, leveling of fields, filling of depressions and

Smoothening of field for irrigation. It saves 30 % water.

Approx. Cost: Rs.3,50,000
