This was a match in which Howe were disorganised at times, but they did manage to score four tries to earn them their first league point since January 23.
It was also the the first time they had scored four tries since November 7.
It took the homesters only four minutes to get the first try, driving Howe off their ball for a scrum near the line for an unconverted try by Adrian Hamilton.
Angus Guthrie had a pass intercepted by Connor Lavery on halfway and he was clear away to the line for another unconverted try.
A break by centre Peceli Nacamavuto ended with Lavery scoring again, but that try was also not converted.
A piece of Howe bone headedness allowed Hagart a penalty attempt at goal which he kicked for 18-0.
Howe came to life when Fraser Clark made a break, Andrew Steven took it on, and Duncan McIntyre scored, but Guthrie hit the left upright with his conversion.
Another break by Nacamavuto led to a try by Sam Knudson, the scrum half, which Hagart converted, and he also converted the next try by Alex Ratcliffe.
The second half scoring was opened by Aberdeen replacement second row Alasdair Mackie who bulldozed over near the posts for their sixth try.
Rob Lind made ground from a scrum, Stewart Lathangie dummied through and Steven went over at the right corner, the try going unconverted.
some slick Aberdeen handling resulted in Lavery collecting his third try which was converted.
James Lawrie got his hands on the kick off and started another move which ended with Clark scoring out on the right, replacement stand off Cameron Ellison making the conversion.
Aberdeen scored their eighth try when Hamilton went through a tackle to touch down, Hogart converting.
However the visitors claimed the lost try, a throw back to last season, when Clark took a tapped penalty inside his 25, and set in train a move which went the length of the park for Fraser Ellison to run over.
The conversion missed.
