3.0 LAND DEVELOPMENT MACHINERY
3.1
TRACTOR DRAWN 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 tractor’s 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.

Power requirement(hp/kW) |
: 55/41.25 |
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.
