| The Institute conducts testing of tractors, power tillers,
combine harvesters, irrigation pumps, threshers , agricultural tyres, engines,
all kinds of farm implements and components. Detailed performance results are provided in
the test reports released on each machine. The brief outline of various types of tests are
as under:
TRACTOR TEST
Tractor test is carried out in accordance with IS:5994-1998 as
amended from time to time. A tractor is subjected to the
following tests & evaluation
Lab Tests
 Checking of
specifications
|
PTO performance test |
Belt pulley
test(optional) |
Drawbar performance
test |
Power lift &
hydraulic performance test |
Brake test |
Air cleaner oil pull
over test |
Noise measurement |
Mechanical vibration
measurement
|
Location of centre of
gravity |
Turning ability |
Visibility |
Field tests:- For Initial commercial tests 50
hrs and for batch test 40 hrs. of field tests with the following implements
Plough/ Rotavator(35
hrs. for I.C.T & 30 for Batch Test ) |
Puddling under actual
field condition followed by Water Proof Test.(5 hrs.) for ICT and 5 hours each
internal field condition and laboratory conditions respectively |
* Note:- Depending upon
implements & field conditions the duration with each implement can be altered.
Haulage test with 2/4 wheel trailers and the gross load
recommended by the manufacturer.
Components & assembly inspection- to assess the wear,
breakdowns, etc.
POWER TILLER TEST
Performance evaluation of power tiller is conducted in accordance
with IS:9935-2002 as amended from time to time. A power tiller is put into the
following tests and evaluation:
Lab Tests
Specification
checking. |
Engine
performance test. |
Rotary shaft
performance test. |
Drawbar performance
test. |
Parking brake
test. |
Noise measurement. |
Air cleaner oil pull
over test. |
Mechanical vibration
measurement. |
Turning ability test. |
Chemical composition
test and wear characteristics test of rotavator
blades. |
Field tests: For Initial commercial tests 75 hrs
and for batch test 50 hrs. of field tests with the following implements
Mould
board ploughing (10hrs.for I.C.T. only) |
Dry rotavation
(40 hrs.for I.C.T & 25 hrs. for Batch tests) |
Puddling under
actual field condition ( 25 hrs for I.C.T. & Batch tests
both) |
* Note:- Depending
upon implements & field condtions the duration with each implement can be altered.
Haulage test
Components and assembly inspection : to assess
the wear, breakdowns, etc.
COMBINE HARVESTER TEST:
Combine harvester testing is done in accordance with IS:
8122-1994 Part-I & IS: 8122-2000 Part-II as amended from time to time. A combine
harvester is put to the following different tests:
Lab Tests
Specification checking. |
Engine
performance test. |
Turning ability
test. |
Location of centre of
gravity test. |
Visibility test. |
Brake performance test
. |
Air cleaner oil pull
over test. |
Mechanical vibration
test. |
Noise
measurement test. |
Field tests: 200 hrs of field test on the following crops are performed
Wheat harvesting
. |
Paddy
harvesting. |
Any other crop (if
recommended). |
Component and assembly inspection: to assess the
wear, breakdowns, etc.
TESTING OF MISCELLANEOUS EQUIPMENTS/MACHINES (On request) :
Paddy
Transplanter :
The Institute is testing transplanters for evaluating
performance of the engine & field performance to assess suitability & its output
in the field.
Tractor Tyres
Drive wheel tyres of tractors are being tested for assessing the
performance on drawbar work as well as wear of tyres on dimension and on mass basis
per unit of time.
Irrigation
Pumps
Irrigation pumps are being tested for power requirement,
pressure discharge characteristics, efficiency etc. as per the requirement of
relevant Indian Standards.
Power Units:
Power units viz. engines under ISI mark certification scheme or
as requested by the manufacturers for different application
Tillage
& Sowing Implements
Tillage & sowing equipments are being tested for material
composition of soil engaging components and assessing the field performance for the
intended purpose.
