Midfielder Eddy Birch and attackers Jordan Harrison and David Brown have all moved on.
Brown has left on loan to Harrogate Railway, he played in their defeat at the weekend, Birch has joined Pickering Town and Harrison has signed for landlords Bridlington Town.
Boss Steve Kittrick said: "These lads all want game time, which is fair enough.
"We have spoken to them all and they have decided to go and get some football.
"We still have plenty of options available going forward and we are also always looking to strengthen."
