Bad battery symptoms
Common symptoms of a bad battery in a Zetor 3011 tractor include hard starting, no response when trying to start, and a clicking sound when the starter is engaged. Additionally, if the battery voltage drops below 12.4 volts when fully charged, it may indicate that the battery is weak or failing.
Basic battery safety
Disconnect the negative cable first, then disconnect the positive cable. Install the new battery, connect the positive cable first, then reconnect the negative cable last. That reduces the chance of shorting a tool against the frame.
