What machine  are you using it on? Are you just taking it in at night, across the cement  or are you working it in a barn?I have a 310 Case with a loader and it comes in around 11,000 lb.s and run that in and out of the barn on the cement and it really doesn't mar the cement much. The little OC-3 is only 3,300 lbs or thereabouts and neither  will  do enough to say so in my lifetime. I don't turn on the cement however.... . only straight in/straight out..... and the pads are all quite warn. Many years ago I used to run a 450 John Deere and used to run that straight in on the shop floor much to the irritation of the boss. <!-- s:lol: --><img src="{SMILIES_PATH}/icon_lol.gif" alt=":lol:" title="Laughing" /><!-- s:lol: -->   If he was around I'd lay down 3/4 inch pine boards and put it up on that.
