Gall adds that farmers also need to install a pressurized vent cap on their tanks rather than the less expensive flip cap. One third of the farms we studied hadn''t followed this drillpressattachments advice."The Pre-Vent cap ($22) seals the tank and holds up to 3 psi of pressure so it reduces the movement of air, dirt, and moisture in and out of the tank," he says.Impact on engine wearThe days when diesel engines were able to burn anything and a trail of black smoke signaled high horsepower are gone. Now, a new generation of diesel engines designed to meet stiffer EPA emissions standards has heightened concerns about fuel quality.

The unique triangular design of drillpressattachments the boom allows for infinite nozzle-tip spacing and nozzle-tip protection while spraying in the field. Visibility from the cab is exceptional and, when traveling from field to field, the boom sits snuggly in a transport cradle.Drawbar hitchIf you''re a producer with a 9000 Series "bareback" tractor or any tractor without a two-point hitch, then John Deere''s new factory-installed optional drawbar hitch is designed for you.The optional drawbar hitch has been developed for use with 177ONT, 16-row, 30-inch; 177ONT CCS 16-row, 30-inch and 1790 planters. This drawbar hitch is the economical choice instead of adding a two-point hitch to the tractor.

Environmentalists have been quick to point fingers at chip mills for devastating forestry practices. But the industry insists it''s "out of the loop" concerning timber cuts, since operators purchase their supply from private landholders. Industry officials are so infuriated, many refused to comment. The line connecting chip mills to clearcuts and destructive forestry isn''t a straight one, but it is visible. Dean Carson of the South Carolina Forestry Commission argues that chips can be transported more efficiently, using less energy, than large pieces of timber, and mills can utilize the whole tree. But processing the whole tree is exactly what has brought the mills under fire: because lumber is chipped into one-inch pieces, any size scrap of timber will do. With new markets opening up for treetops, undersized trees, and forked or crooked specimens, landowners have added incentive to clearcut a site for quick profits, instead of harvesting selected trees to be cut into drillpressattachments boards. And timber previously left behind to continue maturing, or that provided wildlife habitat or eroded to replenish soils, now finds itself in the steely mouths of the chippers. A 1998 U.S. Forest Service report says clearcutting accounts for 13 percent of logged land in the South. And because the chips are needed for everything from rayon and plastics to particleboard and paper, chip markets continue growing. Timber giant Willamette Industries says chip mills allow landowners to merchandise otherwise unusable trees, discouraging forestry practices like "high-grading" (cutting only the healthiest trees). "Clearcutting is often the best tool to assure a rich, diverse forest," claims Willamette''s web site. "Many songbirds and other types of wildlife require open areas for nesting and food gathering."
