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.
A disc drive is a power transmission device that uses a friction disc to make contact between driving and driven components.
A V belt is a continuous reinforced rubberized belt used to connect pulleys in order to transfer rotation.
Pulleys are used to transfer power among the components in equipment through the use of a drive belt.
The most commonly used safety interlock switches are operator presence control switches and ignition switches.
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.
A variety of implements and attachments can be used with OPE.
The most common implement for OPE is the single- or multiple-blade rotary mower deck.
Snow throwers can be attached to a larger piece of OPE such as a lawn and garden tractor.
A water hose or pressure washer can be used to remove unwanted materials from OPE, allowing visual access to most moving components.
Many small engine problems can be avoided by following a regular maintenance schedule, which reduces the costs associated with part replacement and repairs.
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.
The maintenance of a disc drive system usually involves unbolting several components and installing a new disc followed by an adjustment procedure.
Mower deck maintenance consists of flexible belt adjustment and alignment, flexible belt replacement, and cutting blade sharpening or replacement.
To properly maintain a snow thrower, it is critical that the recommendations of the OEM are followed with precision.
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.
Storage requirements, which are specified in the OEM-provided owner’s/operator’s manual, may vary among each different piece of OPE.
If a battery remains installed in equipment during long-term storage, regular charging (about once a month) of the battery is recommended.
The most common types of OPE that require seasonal storage include rotary lawn mowers, snow throwers, string trimmers, lawn edgers, and pressure washers.
