Inch pedal
An inch pedal or inching pedal is a pedal used in many models of mobile machinery with a hydraulic pilot pressure output proportional to the pedal position, or an electronic pedal with a proportional electric signal output. The pedal is used in hydrostatic transmissions to temporarily affect the preset characteristics for hydrostatic gear ratio versus diesel engine Revolutions [per minute|rpm]. It thus allows the operator to "inch forward" or "inch backward" slowly over short distances for fine positioning of the machine. Common applications include forklift trucks and farm tractors.
