A spade seems like a good way to bend a bucket or cylinder.
Prudence, of coarse, is important in all types of tractor operation to avoid tractor damage.
Consider just the force of gravity on the Bucket Solution's Bucket Spade on my Kubota
L3560 with LA805 Loader:
LA805 weighs 1,279 pounds.
LA2296 SSQA H-D, R-B bucket weighs 180 pounds.
Bucket Solutions' Bucket Spade weighs 110 pounds.
Some of the LA805 weight bears on the BS/BS, say 400 pounds.
So FEL + LA2296 + BS/BS total weight = 690 pounds, bearing on the sharp edge of the bucket spade.
Once the bucket spade is positioned in the ground, you push it to depth with wheel power. You do not use FEL hydraulic power to push the spade into the earth.
I used spade first on a Kubota 'B' and now a Kubota 'L' for a total of five years without tractor damage, excavating relatively soft Florida soil. I have removed tons of tenacious Palmettos and planted dozens of trees.
While there may be some instances of bucket problems related to Bucket Spades in the archive, I cannot remember reading a post concerning bucket problems in TODAY'S POSTS since January 2011, when I joined.
There have been a few posts about chain attached spade failures.
I wish Bucket Solutions would produce an SSQA Bucket Spade.
