Bob,
First, to give credit where it's due, I need to correct a mistake in abbreviation-when I wrote PJ, I meant Pequeajim, not Pajoube.
For side mount implements, I've got in mind a bank mower that owes more to a string trimmer than a lawnmower. PT's boom/bank mower wouldn't work real well on my rocky terrain. It would probably be a tossup between the damage to the mower from the rocks, and the damage to everything in the vicinity from the shrapnel.
I've also thought of a sprayer attachment, and an offset ditch scraper.
I could really use the side mounts right now to provide supports for the duct pipe sticking out about 4 or 5 feet sideways from the big ugly leaf blower that's been my latest project. (I'll try to post photos before too long. It works pretty well, but it's not exactly a tour-de-force of elegant engineering). /forums/images/graemlins/tongue.gif
