Police arrested 17 men for alleged hare coursing between Friday and Sunday, including a man from St Albans who was found at Moulton Eaugate.
That man was charged and bailed to appear at court after being arrested on Friday.
Police also escorted men found at Deeping St James to the Cambridgeshire county border after being unable to prove their involvement in hare coursing and their details were passed to Cambridgeshire Police.
Two vehicles were seized over the weekend in the police crackdown on hare coursing, known as Operation Galileo.
Chief Insp Jim Tyner, the Lincolnshire Police lead officer on rural crime, said: “My message is clear. Op Galileo is here to stay and by training our neighbourhood officers in the powers and legislation which relate to hunting with dogs, we are better equipped than ever before to tackle this scourge on farming and rural communities.
“Lincolnshire is closed to hare coursers.”
Arrests were also made in New York, near Boston, Brothertoft, Digby Fen, Stickney and Woodhall Spa.
Police are appealing to county residents to tip them off when they see suspicious incidents in the countryside – and to call 999 at the time they see hare coursers in the fields.
Chief Insp Tyner said: “We encourage farmers and members of the public to report all incidents to us by calling 101, or the 999 system if appropriate.”
