The invention provides engine heating and cab warm air supply equipment and method and an operation machine, and relates to the technical field of mechanical equipment. The engine heating and cab warm air supply device comprises a first control valve assembly, a main loop and a fuel oil heater assembly. A first liquid inlet of the first control valve assembly communicates with a main liquid outlet of an engine. One end of the main loop and a main liquid inlet of the engine are jointly connected to a second liquid inlet of the first control valve assembly, and the other end of the main loop communicates with a first liquid outlet of the first control valve assembly. A radiator of the cab is connected in series with the main loop; the first control valve assembly has at least an open state and a closed state. The engine preheating pipeline and the cab warm air supply pipeline share one fuel oil heater, so that a set of fuel oil heater and an oil supply system are reduced, the integration level is higher, the structure of the system is simplified, the production cost is greatly reduced, and the product competitiveness is enhanced.
