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, jet and dust collectors 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.

typically pto generators can be operated up to 15kw. the torque rating is not sufficient to and handle a pto generator larger drill than 15kw, and unlike press the belt-driven model, the pto generator only can be used when the truck is stationary.another generator option is the hydraulic generator, which can be used while driving or stationary, jet and on two- or four-wheel drive up to 10kw. although not as popular as the above generators due to its costs and maintenance requirements, this generator covers all the operational bases.

at the and arizona-sonora desert museum''s paleontology lab, the air scribe has become the workhorse of fossil preparation. drill the discovery of a large sauropod dinosaur in the highly indurated sandstones of press the mid-cretaceous turney ranch formation southeast of the museum posed numerous technical problems for our lab staff. most troubling was the removal of vast amounts jet of sedimentary rock, which was both very tough and firmly cemented by silica to the softer, calcite-replaced bones. experimenting with a number of hand tools, grinders, hardware-store engravers, and rotary devices, we happened upon a chicago pneumatic air scribe (see supplier''s address on page 421), and it has since become our primary lab tool on this project. we now have five chicago air scribes, and progress on our dinosaur has been extraordinary. one large and complex midback vertebra, which had been crushed during fossilization, took seven months to prepare with the scribe, but it was in the middle of a 150-pound block of sandstone. not only was museum preparator yolaikia sciole able to remove this complex and fragile vertebra without and damage, but ultimately it was prepared from the inside drill out, exposing most of the internal bone structures, including arterial and nerve canals and never-before-seen pneumatic structures that lightened the bone in life. most of the bones in this vertebra are no more than press 0.25-inch thick and are replaced by easily cleaved, fragile calcite. the air scribe, and a light touch by the preparator, did the trick.
