Backhoe update. I'm making progress (Video included)

[chad22]

Well I got quite a bit done to the backhoe. I totally changed the design. It looks totally different. And looks to be much stronger.

The backhoe should dig down to around 6 feet which should be plenty of depth for my use.

Here's a video of it on youtube. YouTube - Update number 1 of my home made backhoe

I was sick with the flu when I took that video yesterday but I couldn't stay in bed and had to get out into the shop anyway.

I've got the last cylinder mounted now. I went and picked it up today at Orschelns. And yes I was still sick with the flu and running a fever as well. lol

I was gonna take a video again today after I worked on it some more. But as soon as I got done painting it a royal blue it started raining so I decided to come home. I would have stayed but the shop leaks really bad. Which were hoping to fix this summer.

Anyway I'll go to the shop tomorrow and get another video of it with it's blue paint.

I forgot to upload another video I had on my camera card. I finally got it uploaded. Here's the link

Great project, can't wait for the snow to melt so I can start digging holes. I know why those prairie dogs have so much fun.

Thanks. I got down to the shop this evening. I took a video but the lighting was bad and the video turned out pitch black for some reason.

But I did take some pics of it with it's blue color and the last cylinder installed.

I can't wait until it's finished. I'm also ready to dig some holes with it. With the progress I'm making. I expect it to be up and running by May or June.

Then I can upload a digging video of it.

I've attached the pics of it I took this evening.

Why did you make the stick & boom so long ?

Having it that long it is going to put a tremendous amount of force on the mount and tractor and it is going to decrease the available force for digging and lifting.

The tubing I bought came in 6 ft lengths. I was gonna cut them down shorter but decided to leave them be seeing as the cylinders wouldn't have enough room to mount.

Well I did cut the stick down about a ft. The part I cut off the stick was used for the linkage on the bucket.

So in other words. If I were to shorten the boom the cylinders that I used wouldn't fit.

The boom is 6ft long and the stick is around 5 ft.

it's hard to pour cold water on somebody who is obviously determined to build.

at the same time, why didn't you stop by your local tractor dealer and look at the backhoes on some of these sub compact tractors that are out there?

even if there is no dealer nearby, there are plenty of pictures available online.

that way you could get an idea of what is required, in terms of structural strength, to stand up to the hydraulic forces you intend to apply.

please have your camera/video equipment running from the very first time you go to use it.

sometimes it's best to have to ability to watch the structural failure in progress to come to a better understanding of the forces at work.

There is plenty of room to cut the boom down. You could have easily made a plate that both cylinder ends mounted to or you could have staggered the mounting locations having the cylinders overlap each other.

As far as the stick goes the pictures show you could have cut it down alot more and still have plenty of room to mount the bucket curl cylinder.

I am really concerned that the forces the hydraulics are going to achieve are going to be way too much for your design. Please keep us posted on your progress and be safe.

I wish I would have though of the overlapping the cylinders idea. That's a great idea.

But since I got all this welded up and everything. I'll try it like it is and see how good it works. If it turns out I need to shorten the boom and stick. Then I will. But I'm hoping for it to work like it is. We'll find out hopefully by June.

I'm a bit concerned myself. Hopefully my design will work out okay. I'll be sure to keep you updated and definitely will get a video when I go to use it for the first time.

I'll try to stay safe.

the metal those cylinders mount to looks mighty thin for the force applied
