My trencher and power broom attachments are selling on ebay right now. They are both bobcat brand but have the ditchwitch/toro/vermeer type attachment plate welded onto the bobcat mt plate. To use on a bobcat, you would have to cut the toro plate back off. Each will sell to the highest bid or I'll take a reasonable offer on the pair. I can ship each for around $150-250 depending on location.
