| 241 | Ground scraper | US11273403 | 2005-11-14 | US20060081385A1 | 2006-04-20 | Charles Huber |
| A ground scraper designed to be pulled by a tractor or the like includes a pair of parallel frame rails with a scraper blade between them and perpendicular to them. The scraper blade can lowered to a preferred depth of scraping and can be raised above the bottom of the frame for towing. Dual-wheeled trucks on the rear of the frame can be raised off the ground to allow the frame to contact the ground for scraping and can be lowered into contact with the ground, also raising the frame off the ground, for towing on roads or the like. The rear of a tongue can be raised relative to the front of the tongue to pick up the front of the ground scraper frame for transporting the ground scraper and then the rear of the tongue can be lowered relative to the front of the tongue, allowing the frame to contact the ground. The exact angle of the tongue can float up and down in order to allow towing on uneven terrain. | ||||||
| 242 | Rake with four-wheel stabilizing system | US10884908 | 2004-07-06 | US20060005524A1 | 2006-01-12 | Harvey Crosby |
| A rake has two side members attached perpendicularly to the rake so as to form an H-shaped frame system. A swivelable wheel is mounted at each corner of the frame. The frame fully stabilizes the rake in a position approximately level with a ground surface as the rake is pulled across the ground by a tractor or other vehicle. The wheels are adjustable both vertically and horizontally by inserting or removing rings on a shaft holding each wheel, and by telescoping parts of the frame into each other. The invention is useful either as a combined rake/stabilizer system, or as a kit for retrofitting existing rakes. | ||||||
| 243 | Box scraper with scarifier | US11025291 | 2004-12-29 | US20050150668A1 | 2005-07-14 | Jim Williamson |
| A box scraper and scarifier has a scraper box and a mid-blade mounted to the scraper box, intermediate a scarifier bar and a rear wall of the scraper box. The scarifier bar, which can be either fixed or retractable, is also mounted to the scraper box. The scarifier bar includes a plurality of chisels for scarifying the soil. Positioned near the rear wall of the scraper box may be a rear cutting blade. Three actuators mounted to the box scraper and scarifier may be used to achieve a desired cut angle for either the mid-blade or the rear blade. Further, a front drawbar assembly and a rear wheel assembly may stabilize the box scraper and scarifier during use. In one embodiment, a shackle assembly attaches the box scraper and scarifier to a skid loader or tractor. | ||||||

| Banko Manufacturing International has developed an operator actuated electro-mechanical drag mat lift assembly that mounts on the rear of existing lawn equipment that provides a platform for mounting lawn care products requiring deployment for use. Our design differs from other deployment systems in that the Banko Manufacturing International design allows the lawn equipment operator the ability to deploy the assembly while remaining seated with just the flip of a switch. Other manufacturers' designs have failed to consolidate the elements necessary into a comprehensive semi-automated concept. In addition, the innovative drag mat design, when used with the lift assembly, provides an effective method of distributing both dry and damp grass clippings improving turf appearance. | ||||||

| 258 | Land surfacing apparatus | US52284 | 1979-06-26 | US4269273A | 1981-05-26 | Hume W. Colville |
| Land surfacing apparatus, comprising an elongate blade and a towing structure which includes a tow connection portion forward of the blade and which is connected to the blade so that the blade can be towed with its longitudinal dimension transverse to the tow direction while biased by its own weight into engagement with the ground with a longitudinal edge thereof serving as a soil cutting edge and a leading face extending upwardly from the cutting edge. The connection of the tow structure to the blade permits adjustment of the blade through a range of forwardly leaning orientations at which it extends both upwardly as well as forwardly in the tow direction from said cutting edge. The blade is carried by an elongated hollow triangular structure which carries ground wheels mounted on supports extending toward the towing structure, and inboard of opposite ends of the blade. A hydraulic cylinder is operable to effect pivoting of the tow structure and hollow structure and cause the ground wheels to be brought into engagement at an extreme forward leaning movement of the blade. | ||||||
| 259 | Tines | US450671 | 1974-03-13 | US3943999A | 1976-03-16 | Ary van der Lely; Cornelis Johannes Gerardus Bom |
| A steel soil cultivating tine has a lower soil working portion and an upper fastening portion. The tine has zones of differing hardness along its length, the hardest zone including the lowermost end of the tine. The tine can take different shapes and configurations, but in general the soil working portion has sides, at least several of which taper towards the lowermost end. The fastening portion can be threaded for reception in a threaded holder. Near the juncture between the fastening and soil working portions a zone of reduced hardness lends flexibility to the tine. | ||||||
