An electric water pump allows the cooling system to operate at the flow required to maintain optimum engine temperature and could eliminate engine overcooling that can occur with mechanically driven pumps. If additional flow is required for a specific application, it can be provided via software commands, not necessarily a larger pump. These electrically driven pumps are designed with fully enclosed, electric motors that could eliminate shaft-seal leakage problems, the most common failure mode with today''s mechanically driven water pumps. The setup lets him cover about 100 acres a day, "if you really stay after it and the conditions are right."Hay wraps save timeHay wrapping equipment is mentioned by several producers as a top management change."A 12-foot discbine has reduced our cutting time in the hay field'' says Keith McConnell, Owen Sound, drillpresschuck Ontario, Canada. "The best thing, though, is the new 648 baler we bought last year with the net wrap. I can''t believe how fast it is. It is like baling with two drillpresschuck balers."Net wrap costs more up front," says McConnell, "but it saves time, fuel, and wear drillpresschuck and tear on our equipment." So begins this detective story tracing the history of the screwdriver back from the first source he consults, which claims it is a nineteenth-century invention. Even the Oxford English Dictionary cites 1812 as the first instance of the word in print Gradually, the road leads back to the mention of a turnscrew, the word for a screwdriver in the Midlands and North of England. Since this is a literal translation of tournevis, drillpresschuck the French drillpresschuck for screwdriver, the author consults Diderot and d''Alembert''s Encyclopedie, where he finds several screwdrivers. We are now back to 1765, and shortly to 1723, the date of the first known mention of tournevis.
