Last summer, we had a brand new Redmax backpack blower stolen from one of our trucks on-site. Last month, our chemical guy was out doing an end of year fert application, and sees a Redmax backpack blower in the back of a pickup in the parking lot. (This was at a townhome complex btw). He walks over to look at it, and lo and behold, it has our unit number and serial number engraved in the outer shroud. (Because for some reason, Redmax only uses a decal that peels off in about a week, so I engrave everything. Springtime, when we stock up on new hand held equipment, the shop sounds like a tattoo parlor with the engraver going) So our chem guy calls me, gives me the S/N, and sure enough, same blower that got ripped off last year. So we call the local cops, they come and collect it, get the plate number and take the blower back to the station. We finally got the blower back, don't know if anyone got arrested or not. I guess you should either a) scrape the serial numbers off of your stolen equipment, or b) don't leave it laying out in your truck bed...it might get stolen.
