hola gentlemen, I got to rent an attachment I've never used yesterday. We of course have been working on this wall and as is typical for us landscapers we come into a filthy environment, do our job without making a mess, and then are told we need to clean up after ourselves... or in this case everyone else. anyways, instead of hand-sweeping a 1/4 mile of asphalt or wasting a ton of water w/ my hydroseeder I called up cat and gave a sweeper attachment a try.. wow did it work great. left nothing but for some dust. anyways, as usually the problem with renting attachments I always want to buy them when I'm done, but if I did buy one I'd want it for my ditch witch instead because we're not usually cleaning on such a grande scale.
