Light disk my @ss. I have one behind a 4-150 and you sure know it's back there. I think it will work the tail off a 2-135. I used to pull one a bit bigger with a 2-155 or a 4-180 and the 2-155 would do ok if you were disking shallow but bury it an it's another story. The 4-180 or 4-210 was a much better match. If you get that 2-135 on any wet spots whatsoever it will be game over right now. If you're just going to go out and play around on some light ground and disk 3 inches deep you will probably be ok. If you have any hills or wet gulleys or heavy soil forget it.
