A friend of mine has the same tractor that I have(1025R) and would like to use a couple of my attachments from time to time. Everything I have is set up for my I match and he's to cheap to buy one for his tractor. My question is how difficult is it to pound out the roll pins which hold the bushings in place on the attachment. I banged one one last night for just a couple min. And it didn't budge. Thanks.
