Kubota ZG222A-AU, ZG227A-AU Common Problems This Manual Covers
Hard starting or no start
The engine is slow to fire or will not start, often from choke setting or a safety-system fault. The engine section covers starting, cold-weather starting, and warming up.
Manual Section: Operating the Engine p. 28Uneven or scalped cut
The deck leaves a stepped or scalped finish when it sits out of level. The adjustment section covers deck leveling and the anti-scalp setup for an even cut.
Manual Section: Adjustment p. 88Weak drive or will not move
The mower feels sluggish or fails to move under load. The machine-operation section covers correct operation and break-in of a new machine that keep the drive strong.
Manual Section: Operating the Machine p. 35Poor blade engagement
The blades bog down or leave a ragged cut in thick grass. The mower section covers cutting height and getting the most from the deck.
Manual Section: Operating the Mower p. 45Battery goes flat or slow cranking
The engine cranks slowly or not at all when the battery is weak or poorly connected. The battery troubleshooting chart helps trace charging and connection faults.
Manual Section: Troubleshooting p. 99Low tire pressure spoils the cut
Unevenly inflated tires tilt the deck and leave an uneven finish. The tires and wheels section gives the correct front and rear inflation pressures.
