Every once in a while I get Lucky!
Picked up a regular duty 61" bucket a guy had on Facebook. His dad purchased it some years ago brand new and was going to buy a tractor to put it on and never did. It had never been on a tractor.
I bought it for $350 and bought $50 worth of material and made it an HD bucket.
I added the 1/4" piece under the top lid. (JD uses 3/16" but I couldn't find 8" wide flat stock 3/16" so I went 1/4")
End pieces are 1/4" and hooks are exactly like the ones on my 72" HD John Deere bucket.
I also added 2 - 2" strips of 1/4" underneath as my big bucket had 4 and this one only had 2.
Have not had the time to purchase extra grader blade and drill bucket for it but I'm pretty sure it will happen.
If I do I will have about $600 in a bucket the dealer quoted me for $1300+ and mine has hooks like 48" and 72".
