I've been told that he's using the drum
Wish I rendered that fork setup. Shit. Well, at least I have something. Drive forward aggressively, and try to angle into those skids. If not and he turns before I can angle in, just press before contact instead assuming it's a (mostly) frontal assualt. Aim to get under. If I do, quickly flip him over. Drive forward while doing so to negate the possibility of him driving off. If he falls or drives off, close the lifter quickly. He's probably gonna aim for my chassis.
Keep him at the very front of the plow to prevent this. Notice how he only has 4 armor. After I flip him over (or after a few attempts if I can't flip him over), just try to slow his drum down. If his drum has stopped, raise the lifter, get him in the dustpan, and clamp before he can spin back up again. Use the very back of the dustpan to stop his drum as I'm clamping him so I don't get any nasty surprises.
Once he's in the dustpan, clamped, with his weapon stopped, his back end will be exposed. Park at one of the flamethrowers and grill his ass
Once the pin timer is almost up, finish off with a release so he reverses on to the flipper. Idk about you, but 4 armor to a long exposure to a heat source probably would damage the motors in some way. If he's under me, my wedge should slow his drum down after hitting it. Try to attempt at doing so. Don't fall for any of his gyro tricks either. Don't drive into hazards and self right if flipped. Drive away to a safe place before self righting if I must (especially because exposed wheels)
Good luck
