What looks like a simple attachment can go very wrong and very right depending on the fabrication and design process.  When you use a tool as much as you do with your bucket, it is worth investing in a great one. 

These heavy duty buckets are made with 1/4" steel and 3/8" end plates .

They have a 3/4" x 6" single bevel, carbon steel cutting edge.

They include a 3/8" thick lateral reinforcement along the entire height of the bucket and a double reinforced base to improve longevity and material handling.

The top of the bucket is reinforced with 3" x 4" x 1/4" square tubing and 3/8" additional steel reinforcements are added underneath the bucket.

Heavy duty buckets ranging from 1.54 to 1.87 cubic yard capacity.

They are recommended for tractors of 120 to 200 hp or telehandlers.
