anybody have the same issue? i have a mtd 25ton splitter and once i get the coupler (that's on the spliiter) onto the 2" ball on my truck or atv.........it's brutal to get off.....i mean really brutal. I had to take the ball off the atv to get the splitter off my atv. i've verified that in the unlocked position the spring device isn't interfering at all. So...I put the splitter on the ball and if i push down a bit on the ball it snaps into place. at that point it's not coming off to easy....and there's my problem. I actually brought a caliper from work to check the 2" ball.....both of mine are within .005". They're fine. I put a new coupler on that I bought from napa and it works great. it's a 2" ball, 2" sleeve, 3500 ton coupler (just like i had). I'm guessing the coupler the splitter came with was machined to tight? Either way, i don't really want to get a replacement part from mtd...i figure they'll send me the same coupler with the same issue. any thoughts?
