Indian Standard

TECHNICAL REQUIREMENTS OF AGRICULTURAL TRACTORS FOR

WET LAND CULTIVATION

0. FOREWORD

0.1 This Indian Standard was adopted by the Indian Standards Institution on 30 November 1984, after the draft finalized by the Pgricultural Tractors and Power Tillers Sectional Committee had been approved by the Agricultural and Food Products Division Council.

0.2 Wet land cultivation, popularly known as puddling is an important tillage operation in the cultivation of transplanted paddy. The agri- cultural tractors are increasingly being used for Lj’et Iancl cultivation. The success of mechanized paddy cultivation with the agricultural tractors depend upon how efficiently it can be operated in wet paddy fields. 11 need was, therefore, felt to formulate an lndian Standard on this subject for the guidance of the manufacturers and users.

0.3 In the formulation of this Indian Standard, assistance has been derived from the Central Farm Machinery Training and Testing Institute, 13udni.

0.4 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accor- tlance with IS : 2-1960*. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

1. SCOPE

1.1 This standard covers the technical requirements for use of agricultural tractors for wet land cultivation ( puddling operation ).

2. TERMINOLOGY

2.0 For the purpose of this standard, the following definition shall apply.

*Rules for rounding off numerical values ( revised ).

3

IS : 11082 - 1984

2.1 Agricultural Tractors - See 11.1 ofIS : %X39-1981*.

2.2 Cage Wheel - See 2.3 of IS : 9939-1981*.

2.2.1 Half Cage Wheel - See 2.4 of IS : 9939-1981*.

2.2.2 Full Cage Wheel - The cage wheel used in place of pneumatic wheels ( tyres ).

2.3 Puddling - The mechanical manipulation of soil in presence of standing water in the field to create an m~pervious hard pan below the puddle zone so as to prevent loss of water through Ieacliing and facilitate the transplanting of paddy seedlings by making the soil softer.

3. CONSTRUCTIONAL REQUIREMENTS

3.1 As the tractor is required to be operated under wet conditions, r”e- treatment to sheet metal should be adequate to prevent corrosion.

3.2 The tractor should have independent braking system.

3.3 The tractor may be equipped with differentiai lock.

3.4 Adequate provision should be made for the drainage of water near foot rest and operator’s work place.

3.5 Outside part should be such that they are not affected c!uring the water cleaning of the tractor as normally tractor requires thorough cleaning with water after puddling operation.

3.6 Where choice for fitting tyre is available, it is advisable to use tyres having broader contact area. .

3.7 Exhaust system of the tractor shou1d be appropriately 1:ojirionccl to

prevent ingress of water and mud during operation.

3.8 Provision for fitting half cage wheel and full cage wh~~cl shall 1~ made. The half cage wheel may conform to the requirements given in IS : 11081-1984.7.

3.9 The sealing of the critical components should be eflect;ve. ‘I’he following critiral components and SyStefilS Slloultl be free fIWI:l Cl:i?): Of

water and dust, mud:

a) I.ubricatin,q oil in the cn,gine yump, transmis:.ion, llydraulic housings, final c!rive housings anJ steering box.

*Glossary of term\ relating to agricultur:ll tractors and power tillers. @pecificatioll for half rage wheel for agrirultural tractors.

IS : 11m2 - 1984

1)) firakc assembly.

c) Clutch assembly.

cl) Rear axle assemb!y.

e) Front axle assembly including stub axle, front wllcel liIIl)s, king pin ant1 ccntre ( pivot ) pin assembly.

f) Starter motor and dynamo.

g) Electrical components, such as magneto, battery: and cut Out.

3.10 Provision shoul~l be made to plug various weep ho!cs or inspection 11olcs provided in the transmission housing, clutch housing, rear axle housing, etc.

4. OPERATING REQUIREMENTS

4.1 All the necessary instructions of the manufacturers for preparing tile tractor for wet land operation should be strictly folio\ved.

4.2 Necessary servicing and periodic maintenance during and nftcr the USC for wet land operation should he conducted in accordance with the printed literature of manufacturers.

4.3 ‘L’apcr plugs usetl for plugging the weep holes or inspection ho!es sl~ould be opened to allow the water to drain out at suitable intervals as recommended by the manufacturers.

4.4 While using cage wheels, for reasons of safety and obtaining good cluality puddle, a suitable implement like puddlcr, disc harrow, rotavator may be used.

5. LITERATURE

5.1 The operator’s manual or other printed literature supplied with tractor should include necessary instructions for preparation, safe operation and the mamtenance of the tractor for wet land operation.

5.2 The manufacturers should also provide the information lvith respect to front axle reaction in terms of the front mass for various usage of the wet lancl cultivation, that is for half cage wheel or fu!l cage wheel to ensure stability and steerability of the tractor. ‘1’11~ mass can be varied by the user depending upon the need.
