J Parker,<p>We have a 20' folding Pro-Tech and love it. The operator generally folds only 1 side at night and both sides of course during the day. I think the 20' is rated at 28 cubic yards. You needs a decent size loader for it. We have it on a Komatsu 340.<p>You said plows on loaders are a waste of time. I'll have to disagree there. We have a 16' Daniels mounted on a little Cat 914. Sure, it does less work than a pusher, but it's far more versatile. Plus, with a plow, you need far less loader than with an equal width pusher.<p>As far as that big BOSS, be advised there is no trip mechanism for that unit. The Pro-Tech has a 10" rubber cutting edge and the Daniels has trip springs. I think you might need to modify that unit somewhat to make it acceptable for parking lot/commercial plowing.
