James Gershfield kept alive Harmen's treble hopes following an almighty battle against first division promotion hopefuls Real Sosobad.
Dan Lassman and Scott Kay had put Sosobad 2-1 up and they had a goal chalked off before Harmen battled back to take the game away from them.
Harmen joint-manager Joe Marsh told JC Sport: "Respect to the Sosobad for putting up a valiant fight but our class finally prevailed; as a squad we are getting stronger and stronger each week with some of the boys stepping up there came to put on some key performances which has seen us go six unbeaten."
Sosobad boss Dan Shafron told JC Sport: "Unfortunately the result on paper doesn't do our performance justice. We were excellent and pushed Harmen all the way. At 2-1 up, I thought we could have gone on to win but lack of concentration from a set-piece allowed them back in the game."
Shafron believes James Law's disallowed goal - 35-yard wonder strike - was the turning point after "the ref gave a very contentious offside decision".
Shafron said: "It's frustrating conceding three goals in the last five minutes, two of which could have been prevented but I really can't fault my boys.
"They worked tirelessly, competed for every ball, played some excellent football and showed real desire and belief. It was a performance collectively and individually to be proud of."
