When equipment in your operation fails for reasons that you don''t think it should have, you have an obligation to tell the manufacturer that he needs to change the design and offer more reliable products. Owners need to attend trade shows and reach out to manufacturers. They need to share their concerns about existing products and provide ideas of what they need in future equipment.Manufacturers constantly relate how little feedback they receive from end users and owners. The product engineers who do attend the trade shows tell how they beg for input and ideas from end users, and only rarely receive any.

The pumps drive Poclain wheel motors, one for each wheel. The rearwheel is steerable and direction control is obtained with a foot control or optional column-mounted shifter.The drive system also incorporates an electric-over-hydraulic Tracloc system designed to provide superior traction control in rough conditions. "With the flip of a switch, the system directs a prescribed amount of oil to each wheel motor to prevent one tire from freewheeling if the unit encounters rough or slippery terrain," Pohl said. "It allows the driver to keep consistent drive power to all three wheels and pull out of bad ground.

Here we have the rhythm of the book, which resembles the surface of a pond disturbed by a thrown pebble. Anyway, there are screws in Ramelli''s book, presuming absent screwdrivers, and we have retreated another century.De Re Metallica backs up again, to 1556, with the illustration of a slotted screw to attach the leather to a bellows. An illustrated manuscript of 1475 to 1490--a sort of household manual for a castle--shows slotted screws fastening a leg iron and a pair of manacles--castle staples. This train of thought leads the author to war, a great stimulus to invention, witness radar and the jet engine. Pollard''s History of Firearms illustrates a fifteenth-century German equivalent of the sawed-off shotgun in which the stock is screwed to the metal. Research in the Metropolitan Museum of Art turned up a screw of the 1480s attaching parts of a suit of armor. Screws were slotted with a hacksaw and the threads were filed by hand until, in 1760, Job and William Wyatt in Staffordshire patented a machine that turned out more consistent screws at the rate of one about every six seconds. The author comments that, a century before the industrial revolution, "their factory was the earliest example of an industrial process designed specifically to shift control over the quality of what was being produced from the skilled artisan to the machine itself"
