Hurst, whose last three-goal show was also in greater Manchester against Rochdale last season, scored with his right foot, left foot and an opening header.
It earned him the praise of delighted boss Gudjon Thordarson who said: "Glynn might have had five, and was outstanding today not just because of his goals but also because of his work-rate and committment.
"I'm very pleased with this win but it was a fight in the end, Bury didn't give up. When we were 3-0 up we stepped off the gas and we can't afford to do that."
In addition to his treble Hurst had another goal ruled out for offside and two more chances saved by Neil Edwards.
In addition Hurst was heading for a fourth in stoppage time when the keeper brought him down. Referee Darren Drysdale handed the ex-Stockport and Rochdale goalkeeper a red card to go with his first-half yellow.
3-0 down Bury at least made a fight of it with Tom Kennedy converting a penalty after Whaley's header had been handled. Whaley himself netted his fourth of the season but despite nine minutes and a further four of injury time the Shakers couldn't prevent a first league defeat in six outings.
"I would expect the players to show character when they are 3-0 down because they are professional footballers" said manager Chris Casper. "What I want to see is the same commitment and attitude when we are 3-0 up."
