I have a 22 ton huskee. I picked up a 4 way wedge from speeco the other day and I couldn't be happier. I started with some small white oak and it sped things up. But being curious and not heeding the instructions, I decided to test it on something bigger. rolled a 22inch round of red oak over and hoisted it up and to my surprise, chewed right through it. The wedge cost me 66 bucks and would pay more now that I have used it
