<p>An engine device provided with an engine (70) as the power source, an exhaust gas purifying filter device (60) which is disposed in the exhaust path of the engine (70), and a control means (311) which performs low rotation control for reducing the rotational frequency of the engine to a predetermined first low rotational frequency when a preset low rotation condition is established. The control means (311) is configured in such a manner that, when both the low rotation condition and a preset forced regeneration condition are established, the control means (311) maintains the rotational frequency of the engine at a second low rotational frequency in order to minimize a reduction in the temperature of exhaust gas, said second low rotational frequency being higher than the first low rotational frequency.</p> |
