I found this Hay Budden being used as a ballast on an Orchard Tractor in Dallas, Oregon

This was a $35 farm find in Oregon.  

Nice find!  It reminds me of a "metal block" that we used as a tractor weight in our orchard growing up.  My dad said he got the block at an auction and was used for metal working.  Had lots of grooves and holes. Didn't give it much thought till another thirty years passed and I was getting more into metalworking.  I realized it was a swage block.  Went back to the homeplace now owned by cousins and asked my cousin for it and brought it home.  167 lbs from what I can make out from looking online.  I still need to make a stand for it.  That will be on the back burner till I modify my workbench to hold a hydraulic lifting arm that I had got for my pickup....we call this a circular vortex at our house....one project has to be done to complete another project to do the third project!
