SPECIFICA'fION FOR SHAFT ASSEMBLY FORROTAVATOR FOR POWER TILLER

o. FOREWORD

0.1 This Indian Standard was adopted by the Indian Standards Institu­tion on 28 November 1986, after the draft finalized by the AgriculturalTractors and Power "fillers Sectional Committee had been approved bythe Agricultural and Food Products Division Council.

0.2 Rotavator is an important equipment attached with power tiller forwetland and upland cultivation. Shaft assembly is an important assemblyon which blades are fitted. To ensure interchangeability in various makesof the rotavator, a need was felt to prepare this standard.

0.3 Power to rotary shaft can be transferred either from one of two endsor from the centre through chain and sprocket. Considering the presentmode of transmission in most of the indigenously manufactured powertillers, the essential dimensions have been provided only for the rotaryshaft having po\ver transmission at the ends.

0.4 For the purpr)s(-~ of deciding whether a particular requirement of thisstandard is complied with, the final value, observed or calculated, express­ing the result of a test or analysis, shall be rounded off in accordancewith IS: 2-1960*. The number of significant places retained in therounded off value should be the same as that of the specified value in thisstandard.

1. SCOPE

1.1 This standard specifies materia), dimensions and other requirementsof shaft assembly for rotavator attached to the power tiller.

2. MATERIAL

2.1 The material for various components of the assembly shall be as givenin Table 1. The material should conform to the relevant Indian Standardand grade given in col 4- and 5 of Table 1.

6. WORKMANSHIP AND FINISH

6.1 The rotary shaft shall be free from cracks, scams and other visualdefects which may be detrimental in use.

6.2 The rotary shaft shall be free from rust and shall have a protectivecoating which will prevent surface deterioration in transit and storage.

7. MARKING AND PACKING

7.1 Marking - Each rotary shaft shall be marked with the followingparti culars:

a) Manufacturer's name or recognized trade mark; andb) Batch or code number.

7.1.1 Each rotary shaft may also be marked with the Standard Mark.

NOTE - The use of the Standard Mark is governed by the provisions of theBureau of Indian Standards Act 1986 and the Ru lei and Regulations made there..under. The Standard Mark on products covered by an Indian Standard conveys theassurance that they have been produced to comply with the requirements of thatstandard under a well-defined system of inspection, testing and quality control whichis devised and supervised by BI S and operated by the producer. Standard markedproducts are also continuously checked by BI S for conformit y to that standard as afurther safeguard. Details of conditions, under which a licence for the use of theStandard Mark may be granted to manufacturers or processors, may be obtainedfrom the Bureau of Indian Standards.

7.2 Packing - The rotary shaft shall be packed for safe handling intransit as agreed to between the purchaser and supplier.

8. SAMPLING FOR LOT ACCEPTANCE

8.1 Unless otherwise agreed to between the purchaser and the supplier,the sampling of the rotary shaft for lot acceptance shall be done in accor­dance with 3 of IS : 7201-1974*.
