Trencher attachments for the Farmtrac 555?

[VanWert1]

I own a Farmtrac 555, and I am wondering if anyone knows of a trencher attachment that is made for this tractor? Been looking online and haven't been able to find any information. Any help is appreciated

If your talking about a pto driven tooth trencher, I've been told they require a "creeper" gear. Low range 1st gear is still too fast.
If your talking about a 3pt subsoiler then just google subsoiler. TSC has them, as do most hardware stores.
