A young Tannadice team won 4-1 against the Highland League side, with David Goodwilie grabbing a hat trick.
A crowd of around 400 turned up to pay tribute to long serving Mechanics man Neil Whyte, but David Goodwillie was the star of the show, grabbing a hatrick which included two penalties.
The Tangerines' striker converted the first after seven minutes after Marco Andreoni was brought down by John Mutch.
Although United had further chances, mainly falling to Goodwillie, there was no further scoring before the break.
Just two minutes after the re-start, Goodwillie capitalised on an error by home keeper Stuart Knight for his and his side's second.
And twelve minutes later he completed his hat-trick, netting a second from the spot after Ryan Dow was felled in the box by Fraser Bremner.
The goal of the game came midway through the second period, Marco Andreoni crashing home a fourth from 25-yards.
The hosts consolation counter came four minutes from time, David Penwright netting after being played in by Charlie Brown.
