A 1971 price sheet lists a model T-B Shredder Grinder for the 1455, 1476, & 1477 tractors. ....Also, a model T-B-18 for the 1886 tractor. .....Both of the above attachments were made by Amerind-Mackissic.
The shredders for the tube-frames mounted in front. .....I never saw the units for the large frames, so I can't say.
