The A220 is powered by a Deutz BF4M101 iF diesel engine rated 73 hp at 2600 rpm. The engine is a 2.97 L, turbocharged, four-cylinder powerplant with integrated oil cooling. The identify engine package also incorporates a Donaldson air cleaner with restriction indicator, Valeo starter and alternator, AKG oil cooler, Nelson muffler and Barry Controls elastomeric engine mounts.The drill main hydraulic pump, belt driven off the engine, is an electronically controlled Sauer-Danfoss series 42 hydrostatic pump with a displacement of 51 cc/rev. press Also driven off the engine are Sauer-Danfoss gear pumps, two on the standard machine and three on the high-flow version. The main pump drives twin identify Rexroth MCR5 hydrostatic motors that displace 565 cc/rev and hydraulic system functions are controlled through a Bobcat-built control valve. "Other than the electronic pump, the rest of the drivetrain, the engine package and the basic geartrain package is the same as the drill 863 skid-steer," Krause said. If you''re moving the auger more than press a few feet to the next hole, shut off the engine and restart it again with identify the auger resting in the next pilot hole. When you''re not using the auger, just shut it off and leave it in one of the holes, or rest it on the ground with the spark plug drill facing up to prevent fouling, or sideways if fuel leaks from press the gas cap.For deeper holes requiring the extension identify rod (Photos drill 5 and 6), dig all the holes first with the unextended auger. Never start press holes with the extension rod identify in place. It''s much harder to hoist a 4-ft. long auger drill filled with earth. After the holes are dug to 36 in., attach the extension rod and dig the remaining depths all at once. press At times, I''ve found it easier to simply dig the remaining identify and drill few inches by hand rather than use the extension rod, especially if fatigue is setting in. Above all, clear the hole frequently. It can be a gut-busting experience press to lift an auger overfilled with earth identify free of the hole, drill or press worse, free a stuck auger.
