Substitute Harry Clifton notched the only goal of the game late on as Grant McCann's side moved into the automatic promotion spots.
James Maxwell produced a daisycutter that warmed the gloves of Harrogate's James Belshaw in a tame first half. The visitors had better sighters of goal in truth: Ted Sharman-Lowe produced a fine save to keep out an acrobatic attempt from Josh March from close-range and was in the right spot to clutch an Anthony O'Connor header from a free-kick.
Oliver Sanderson then blazed over a better chance for the visitors, after evading Charlie Crew in the box.
Rovers toiled second half and just when it looked as though it would end goalless, Clifton popped up with the winner - albeit thanks to a slice of luck as the ball squirmed under Harrogate's James Belshaw.

10. Ethan Ennis 6
Full league debut and the loanee did ok. Some lovely flicks and turns but also times where he made the wrong pass, as is to be expected at such an early stage in his career. Photo: Andrew Roe/AHPIX LTD
11. Joe Ironside 7
Never gave the Harrogate backline a moment's peace as he hassled, harried and scrapped. Gave his all to the cause. Photo: Howard Roe/ahpix.com
12. Harry Clifton 7
Diligent in his defensive duties when he came on and scored the winner, albeit thanks to a huge dollop of help from Belshaw. Photo: Howard Roe/ahpix.com
