Abstract: An open center trailer with spring suspended axles which straddle a detached cargo bed, which was loaded on the ground, said trailer level lifts the cargo bed by pulling said cargo bed up its channel ramps to an elevated transport height, and consequently level lowers and detaches from this load bed at another location. This load may be a cargo utility platform, or an enclosed cargo box, or a horse traveling compartment, or a dump bed, or a highway light, or a traffic speed sign.

Abstract: A brush chipper that enables easy and ready access to frequently maintained areas of the chipper comprises a chipper-knife assembly, a feed-roller assembly, and a sliding apparatus that allows the feed-roller assembly to move away from the chipper-knife assembly. This sliding apparatus, preferably, includes at least one track and at least one friction-reducing apparatus. The brush chipper preferably includes a chipper-knife assembly that comprises a knife with at least one threaded opening for attaching the knife to a support. To attach the knife to the support, a bolt threads through the support to secure the knife. The bolt includes a head and a stem, and the support is positioned between the knife and the head of the bolt.

Abstract: A brush chipper for chipping wood and debris into smaller pieces. The chipper includes a feed hopper for inserting the material, and upper and lower feed rollers that prepare the material for chipping in the main body of the brush chipper by a chipper disc and bed knife. Debris that collects in a chamber below the lower feed roller is vacuumed out into the main chipper body by fan blades attached to the chipper disc. Components of the brush chipper requiring frequent maintenance, including the disc components and bed knives, are easily accessed because of hinges that allow the feed hopper and the upper body of the brush chipper to swing open.
