- This is a video on how we chose to make a ripper attachment for my Kubota KX040-4 mini excavator. This video contains poor welding, some lucky welding, and us trying out my new LOTOS 5500 plasma cutter on 1/2in thick plate steel. Enjoy!

nice work
That turned out well. A pushing point as mentioned would be a great addition.
Have you thought about welding on a ripper tooth?
The quick attach ears could use some more passes of weld.
I do believe the 3 pieces sandwiched together are more substantial than one 1-1/2" plate. At least for the welding point on the plate. I like the idea that the outside plates are a tad smaller than the center one.
Sweet ripper, c'mon man... no joke
Just ordered my ears for kx033-4 picked up a piece of 1in hardox AR500 steel 130.00 from a local steel supplier went straight to the scrap room
nice job!
Nice job!
I so want a ripper. Thanks for the tutorial. I may try my hand at making one…
You're welcome, thanks for watching. Good luck building yours.
Great work;

The project turned out nicely. I'm definitely going to look into fabbing 1 rather than purchase. I thing I was noticing in last part of the video, baring on the tree to push over with the thin cross section is a little trickier than with a bucket. Maybe weld a flat plate across on the backside up near the ears to better control the tree.
Yes, I like that you also noticed that problem with this design. After using this ripper on a dozen or so 8-10in dia red oaks now (50+ ft tall, give or take) the biggest issue I have with it is the dangerous slipping at that critical moment when you need to push. I think I want to weld a pair of points/wings off the corners of the base plate to prevent losing the tree to the side if a slip occurs. Also, maybe another improvement would be some stubby bolts to act as teeth along the outer radius of the ripper to help bite in when pushing, instead of having to point the tip into the tree. Thanks for the comment. Hope to hear more from you!
I LIKE TOO MUCH !!!! this is a super fabrication and you'll have a lot of good work done with far less costs, because moving far less earth !!! also time saver ...... Best regards friends from French Guyana !!!
Thank you!
Nice job! How long was your basic ripper? About 24 inches?
Probably something like that. We were just trying to mate the point of the ripper with the thumb, so I didn't really ever measure to see what the length was
@@alwayssomethinggood9244 Spot on decision!! Always see these things mis-matched and it drives me nutz! I think you should have brought your gussets out to almost the edge of the plate for the best strength(at least the outer ones) JMO. Great build, I'll be "borrowing" this idea :)
Would it have been cheaper to buy one. What was your cost
The quick connect ears were around $50, the 1in plate and gussets were around $50 from a local machine shop to cut them square so they fit well, 1/2in plate steel was around $285-300 if I remember correctly. Maybe $10 in welding supplies.
@@alwayssomethinggood9244 That's Awesome. Wish I had your ability with steel.
Thank you, I dont consider myself a great fabricator. My start was just helping fix broken equipment on a farm when I was younger. My advice to anyone interested in fabrication is to invest into a simple stick welder, watch some videos on it, and try to make a few welds on scrap steel pieces laying around. You'll be surprised at how useful of a skill it is. And, if not, just sell the welder and get your investment back. Hope to hear more from you on future videos!
