Ah yes. My chain top-link. Good eye. Until I find or build a cat 1 hydraulic link, the chain is the way to go when mowing grass on slightly uneven ground. When in the brush, the solid link goes on.
Anyways, the trailer is an Appalacian, made somewhere in Ohio, sold locally by a used car dealer as a sideline. 18' diamond plate deck, electric brakes. $2200.
It doesn't stay clean long. I have a pressure washer that spruces it up nicely.
