The “Swaraj 724 FE” tractor had undergone “Initial Commercial Test” at this Institute

and a test report No.T- 413/840 released on March, 2001 and “Swaraj 724 XM” tested under

Variant Test vide test report No. T-686/1192/2009 released in August, 2009. The firm has made some changes in the technical specification of tractor and had requested vide letter No.

no. 20/1702073 dated 16.02.2017 for supplementary testing of “Swaraj 724 XM” tractor.

The applicant informed that the last chassis cut off number and engine serial number of

tractor model “Swaraj 724 XM” and engine model number “RV2TRXM” generated on

production line is WQTM14705029216 and 38.1337/SNL3786S respectively.

Now the applicant vide letter No. 20/1804036, dated 10.04.2018 has declared that the

base model “Swaraj 724 FE” tractor is obsolete and submitted last chassis cut-off number as

WQTD10705026814 and requested to consider “Swaraj 724 XM” tractor as a base model
