Culter survived an early scare to secure all three points in a game that was often fractious, with both sides giving no quarter.
Jamie McAllister scored yet another hat-trick as he moved ever closer to Neil ”Toastie” McRitchie’s all-time season record of 64 goals in the Junior leagues.
Deveronside ended up with nine men, while Allan Youngson was also shown a red card late in the game.
The Deesiders now sit proudly clear at the top of the table, while closest rivals Hermes drew and Banks O’ Dee lost.
The home side were first out of the traps with Duncan Philip having two shots blocked before Culter could get going.
The visitors eventually got into the game when Jamie McAllister followed up on a spill by Sean McIntosh, and the ball eventually fell to Ian Leith, but his attempt flew well over.
Culter were now pushing forward at every opportunity but were caught napping when a great Scott Davidson shot flew past Neil Duffy in the Culter goal.
At the other end, Jamie McAllister went close following a superb turn in the box.
Culter equalised with a goal of high quality when Davie Greig waltzed past his marker before crossing the ball for Jamie McAllister, who finished off with his usual aplomb.
Late in the first period, Deveronside crept back into it, with both Stuart Flett and Scott Davidson going close.
The Culter management team made a change at the start of the second half in an attempt to bolster the midfield with Adam Wilson replacing Scott McArthur, and it didn’t take him long to turn the game when he was felled in the box by Ernie Milne, who earned himself a yellow card.
Jamie McAllister stepped up to send an immaculate spot kick high into the net.
The Deesiders then made another telling change, with Allan Youngson replacing Ian Leith as they sought to build on their lead, but it was Dod McBain who almost grabbed a third, but the Deveronside ‘keeper saved well.
Hesitancy in the Culter defence almost let the home side back into it, but Andy Sim came to the rescue when he blootered the ball off the line from a Mike Smith goalbound effort.
The game looked over as a contest when Jamie McAllister released Allan Youngson who sent a telling cross from the left across the face of the goal, and the ‘keeper could only palm the ball into the path of Dod McBain, who stroked the ball home.
It was all over bar the shouting with nine minutes to go, when a Dod McBain fizzler was spilled by the ‘keeper and Jamie McAllister was on hand to poke the ball into the empty net.
Although the game was over as a contest, the action continued to enthral the crowd and the referee had no option to send Stuart Flett for an early dook for retaliation.
With a little fewer than two minutes of normal time remaining, both Allan Youngson and Colin Legge were sent packing following an altercation in the middle of the park.
A great three points for Culter at a difficult place to win.
