The lower sieve on my Tr86 is getting pretty loose, so I picked up a new Harvest services sieve with the plastic louvers today. A lot cheaper than the New Holland and can't seem to find a Loewen or a good used one. The fingers are shorter than the one I have and the spacing is wider between the wires. My old one is 1 1/8" and I think the new one is 1 9/16". Anybody using these? I eventually would like to use this with the rigid air foil chaffer I got a year ago but haven't gotten installed yet because I still don't have the divider kit.
