Iron-base alloys, the most widely used hardfacing materials, combine versatility with moderate cost. They achieve wear resistance by forming carbides and martensite, a hard matrix structure that forms on quenching and toughens with tempering. Pearlitic alloys, usually containing less than 0.30 percent carbon, are comparatively soft and ductile.Nickel-base alloys resist corrosion and heat better than iron-base alloys, They come in three types, depending on the hard phase (boride, carbide, or Laves) that forms on cooling, In boride-containing alloys, large amounts of chromium borides provide wear resistance.Cobalt-base alloys provide more high-temperature corrosion resistance than iron-base and nickel-base grades. Carbides or Laves-phase give wear resistance.

The new separator on the 7460 reduces the amount of green bolls and rocks entering the cleaner. This increases the life of the saws and puts fewer green bolls in the basket, which saves money through reduced ginning costs.Cleaning capacity is also enhanced because of new finger grates that are six inches wider. This design facilitates the use of all 60-inches of the on-board field cleaner.Other cleaner improvements allow faster field speeds, with less plugging, and reduced maintenance time. A new lower saw reclamation brush on the lower saw drum grabs cotton before it falls out of the cleaner and guides it to the basket. This puts more cotton in the basket and less in the burr trail, which improves turnout.

Now one person can do this alone. It''s especially important if you have a gooseneck hitch in the bed of the truck that you need to get to and likewise sometimes need the topper cover. The following is a look at many products that were introduced at or since the Outdoor Power Equipment Institute''s (OPEI) 20th annual International Lawn, Garden & Power Equipment Exposition in October 2003 and will be available in 2004.Hydraulic-driven trimmerDesigned to attach to any zero-turn mower, the H model hydraulic-driven trimmer tackles the toughest trimming jobs with ease. Its users can remain seated while trimming under fences: around poles, tombstones in cemeteries and guardrails on highways; and along driveways and sidewalks. The 3 hp., 8,500-rpm unit features foot controls for the on/off switch and for the lateral movement of the trimmer.
