  1. Chapter 5 Outdoor Power Equipment Devices Mechanical Drive Systems • Mechanical Switches • Implements and Attachments • OPE Maintenance • Storage

  2. A hydrostatic drive is a power transmission device that uses pressurized fluid to provide power to equipment without direct contact between driving and driven components.

  3. A disc drive is a power transmission device that uses a friction disc to make contact between driving and driven components.

  4. A V belt is a continuous reinforced rubberized belt used to connect pulleys in order to transfer rotation.

  5. Pulleys are used to transfer power among the components in equipment through the use of a drive belt.

  6. The most commonly used safety interlock switches are operator presence control switches and ignition switches.

  7. A PTO switch is used to control a PTO function on a lawn and garden tractor. It is typically located on the control panel of OPE.

  8. A variety of implements and attachments can be used with OPE.

  9. The most common implement for OPE is the single- or multiple-blade rotary mower deck.

  10. Snow throwers can be attached to a larger piece of OPE such as a lawn and garden tractor.

  11. A water hose or pressure washer can be used to remove unwanted materials from OPE, allowing visual access to most moving components.

  12. Many small engine problems can be avoided by following a regular maintenance schedule, which reduces the costs associated with part replacement and repairs.

  13. When replacing a flexible belt, it is helpful to sketch the belt routing diagram on a sheet of paper prior to removing the existing belt.

  14. The maintenance of a disc drive system usually involves unbolting several components and installing a new disc followed by an adjustment procedure.

  15. Mower deck maintenance consists of flexible belt adjustment and alignment, flexible belt replacement, and cutting blade sharpening or replacement.

  16. To properly maintain a snow thrower, it is critical that the recommendations of the OEM are followed with precision.

  17. Common engine storage procedures include adding fuel stabilizer to a tank that contains fuel, sealing the fuel tank, changing or adding new engine oil, and covering the engine with a plastic sheet.

  18. Storage requirements, which are specified in the OEM-provided owner’s/operator’s manual, may vary among each different piece of OPE.

  19. If a battery remains installed in equipment during long-term storage, regular charging (about once a month) of the battery is recommended.

  20. The most common types of OPE that require seasonal storage include rotary lawn mowers, snow throwers, string trimmers, lawn edgers, and pressure washers.
