it was originally designed to be water filled, but it rusted out long ago. filled it with quickrete about 7 years ago. i figure i'll use it till it falls apart. i was just going through the bearings and they look ok, but the main shaft has some bad pits in it. i think it should be ok since it doesn't spin very fast.
i am painting the new tow bracket kubota orange this afternoon and regreasing all the "needle" bearings (they about as big around as 5/16" dowel rod) and it should be good for another 10 years or so! works great for rolling flat mole hills to found out which are active tunnels. i've also compacted fresh white rock with it with good results.
