For application of scientific water management techniques various agricultural operations are required to be done like earth moving, levelling, bunding, filling pits, makingwidedrainandroads,backfillinegt,c.Blade terracers are commonly used for this purpose. Aneed has, therefore, been felt to bring out an Indian Standard to help the manufacturers to produce quality blade terracers. Thisstandard wasfirstpublished in 1981andhasbeenrevisedtoenlargethescopeofthestandardbyincorporating therequirements ofIS7353 :1974’ Specification forbladefortractor-operated terracer’ andtoupdatethestandard. The figures given in the standard are intended to serve only as illustrations of components and dimension of blade terracers and should not be considered assuggestive of any standard design. For the purpose of deciding whether aparticular requirement of this standard iscomplied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with 1S2:1960 ‘Rules for rounding offnumerical values (revise~’. The number ofsignificant places retained inthe rounded off value should be the same asthat of the specified value inthis standard. 1S9813:2002 Wwfh?mm *wl-Rm * N-TR- Mm (~ y-~~) Indian Standard TRACTOR-OPERATED BLADE TERRACER — SPECIFICATION (First Revision) 1 SCOPE Thisstandardprescribes thematerials, dimensions and otherrequirements fortractor-operated blade terracers. 2 REFERENCES The following Indian Standards contain provisions, which through reference in this text, constitute provisions ofthis standard.
