Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I'm restoring an old Ariens Sno Thro and one of the rakes is seemingly locked to the shaft. Guy at work put it on a 40 ton hydraulic press and it still didn't budge - just started distorting the rake. He didn't heat it though.

I have a second parts snowblower and the rake is stuck on that one as well. The difference is that one is on the "closed" side of the gearbox so I could remove the axle shaft if necessary.

I'm was thinking of getting as much penetrating oil on it as possible, putting a gear puller on it, leaving ot for a few days, tighten the puller, etc. Any other suggestions? Both gearboxes are nice and tight and they're the old cast iron ones so I'd like to rescue both of them.
