McCombe made over 200 appearances for the Vale Park outfit after previously enjoying spells with Huddersfield Town and Hereford United, respectively.
After putting pen to paper, the 6 ft 2 defender said: Â "Hopefully we can kick on from the players' achievements last season and have another good year. Â I've had quite a bit of interest this summer [from other clubs], but after speaking to Paul (Cox) and the rest of the staff, it seems like this club is heading in the right direction. Â
"I'm a centre half who gives 100% and I'll be giving everything now for Mansfield," he added.
Manager Paul Cox said: Â "We've signed an accomplished centre half in John who already has promotions on his CV. Â He is a commanding player who will add knowledge and experience to our defence."
His contract will commence on 01 July 2013. Â
