Abstract: A grass and soil trimming system comprises a motor driven yard tool. The tool has a housing in a generally cylindrical configuration with a periphery and a female threaded interior and an interior locking screw. The female threaded interior of the mounting screw is adapted to screwably couple to a male thread of a drive shaft on the tool. A first pair of metal cutting blades is coupled to the periphery. The blades are adapted to cut and dig soil. The blades have a generally triangular configuration. A second pair of metal cutting blades is coupled to the periphery. The blades are adapted to cut grass. Each blade has a generally triangular configuration. The second cutting blades have a generally 90 degree bend.

Abstract: A moveable tailpiece for use in association with a slip form on a curb forming machine. The tailpiece is selectively rotatable from a parked position, away from the slip form, to an engaged position at the end of the slip form. The tailpiece has the profile corresponding to a lowered curb profile as required to form, for example, a driveway access or handicap ramps. Utilizing the tailpiece in a curb formation considerably reduces the amount of manual finishing work required to produce an acceptable curb.

Abstract: A folding ramp is provided that includes an upper ramp, a lower ramp, and at least one handle assembly for providing ease of transport of the folding ramp. The upper ramp extends between a first end and a second end, and includes an upper ramp loading track, an upper first side support, an upper second side support, and a vehicle mounting member. The lower ramp extends between a first end and a second end, and the lower ramp includes a lower ramp loading track, a lower first side support, a lower second side support, a ground engaging member, and the rotation member. The upper ramp and the lower ramp include a rotation member that extends between the upper and lower first side supports and the upper and lower second side supports to allow rotation of the lower ramp relative to the upper ramp. The lower ramp loading track includes a first side and a second side and extends from the first end of the lower ramp to the second end of the lower ramp.

Abstract: A clearing chain is mounted on a mobile track maintenance machine for excavating ballast material from a track bed. The chain is composed of shovel-type clearing members for gathering the ballast and intermediate chain elements positioned between the adjacent clearing members and connected thereto by means of chain joints, thus forming an endless chain. Each intermediate chain element comprises two chain joints spaced from one another in the longitudinal direction of the clearing chain. The chain joints are designed for receiving a hinge pin articulatedly mounted in the joint and releasably fastened to the clearing member.
