TERRACE BLADE
.
|
Features:
Terrace blade attached to tractor with the 3-point linkage system and
is hydraulically controlled. It consist of replaceable blades attached
to curved steel body, side wings and indexing arrangement for tilting
and angling of the blade. The blade has provision of reversing back
for filling

Cost (Rs): 30,000-40,000 |
3.2
SUB-SOILER
 
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
TOP
Power Requirement(hp/kW) : 55/41.25 and above
tractor |
|
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 |
 3.3
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.
