CPU systems are unique to Parker and provide a simple solution that reduces interference between functions without bdt10a the need for individual compensators or load sense shuttles. Spools are tailored to provide the maximum required flow for the function hydraulic at the pump compensator pressure and can be flow compensated to reduce interference.Outriggers, steering and brake manifolds can be put in parallel with the main valve where signal shuttles send the highest load signal to the pump. As with a typical load sensing system, the pump will seek an intermediate pressure position. But if lift or telescoping functions are activated, the signal line is blocked and the pump goes to its compensated setting.

The land, which had been neglected for many years, consisted of about two hydraulic acres of lawn, another pump two acres of badly overgrown pasture and the remainder was wild woods. We knew we needed a tractor to help us take care of it all, but what kind, how big, what features and how much were all questions bdt10a we hadn''t a clue how to answer. Since then hydraulic we''ve learned a lot about tractors from friends, neighbors, tractor dealers and, of course, the Internet. We also learned we weren''t alone: Lots of other people moving from a city environment to a rural one had many of the same questions about tractors. This article is condensed from the information we''ve learned about pump tractors over the past several years. I decided to gather the common questions and answers we''d discovered into a Web site called "The Small Tractor FAQ (Frequently Asked Questions)." You are welcome to visit bdt10a the Web site (www.andrew.cmu.edu/user/kb13/TF_home.htm), hydraulic which contains links to tractor manufacturers, implement pump suppliers, tractor discussion groups and lots of other information and resources for and about small tractors.
