Angry Beaver project (FEL build)

   / Angry Beaver project (FEL build) #81  
The John Deere quick attach system looks to be a fairly simple system, so if I ever get to that point, that might be the way to go.
In going back and looking at the hydraulic adapter you made for the Beaver, I noticed the two ports appear to be slightly off center from what I think I have found after disassembling that connection on my tractor. It's possible the photo of the adapter in the picture shows some distortion due to angle of the shot, so that might not be the case. Without removing the tubing assembly from the pump to get a much better look at it, I had made a steel template and drilled the bolt hole on the same center line with the two ports in my adapter. Three closely sized pins were used to check the fit between the bolt hole and two ports before marking and drilling the remaining two bolt holes, so hopefully when finished the part will work OK.
I increased the diameter of the adapter to 3" and I believe it is about 1 3/8 thick. With the increased diameter I was able to use a 3/8 pipe tap and actually drill two ports into the high pressure input port and just the one hole into the pressure return port. I figured I could use the second pressure port for a pressure gauge or possibly another attachment point. I haven't bolted it onto the tractor yet, and will have to plug the pressure port that will go to the FEL and connect that extra port to the return port until I get to the point of completing my project.
You have done an awesome job with that tractor thus far. Keep the info coming. Maybe one day I'll figure how to place photos on this site and can show my progress when I get this project off the ground.

You will need to remove the dishcharge line from the pump to the three point inlet. The holes are off center. You will have to remove then to get any chances of making it work, as of now you are just drilling holes in the dark... There isn't much room for error with 3/8 npt. The first one I made only had a few thousandths clearance between both ports, and being that I made it with no cnc mills or fancy measuring software, it was too close. When the pipe thread was tightened down and the hydraulic cylinder bottomed out causing a pressure spike, it ruptured into the bolt hole cavity.

So you are saying that the bolt hole and the two pressure ports are not drilled on the same center line on your tractor. These tractors are pretty well built and I can't imagine the parts being that much different from unit to unit. I suppose this will require a little more investigation.

I might just have to remove the pressure line from the pump, but trying to avoid that if possible. I have been able to install three close tolerance pins into the outer bolt hole and the two ports that are in line with it, and insert all three into the companion part on the pressure line, but will certainly recheck that before installing the new part.

I believe the 3/8 pipe tapped holes will be well spaced because of the larger outside diameter of the part which allowed me to drill the tap drill holes to a good depth and maintain clearance between the bolt holes. The two .317 holes that I drilled into the pressure port did break into one another very close to breaking through to the .317 pressure port. That's no problem, because it all goes to the same source. I'm still miles away from where you have gotten, but plugging along.

I checked out your new thread, and am slightly amazed that the little tractor can handle some of the tasks you have put it to.

Started on my quick attach front end. I have hay forks (with grapple soon), pallet forks , bucket and a top secret front attachment in the works....

I got to try out my rock/brush/hay rake today. I got this with the old loader setup that I cut apart and re-engineered to fit my tractor. I believe it was a hay fork. I added some 1/4" angle reinforcement at the top of the 1" tines. I'm going to weld in some supports on the bottom of the tines and and a grapple for moving brush and rocks. I also added a quick attach similar to john deeres QA

Grapple is one of the most useful tools to have. I think the tines on that old hay rake won't be strong enough. Time will tell I guess.

I like the quick attach, I have an idea of one for myself but it will hopefully be a little bit lighter in weight and also not require modifying the bucket. Before I can do it however I'll need to make the grapple and snow plow all have the same mounting geometry as the bucket which they currently do not.

the tines are bigger than 1"... 1 1/8". like I said I want to add some supports between the lower tines. I'm also going to add more of a hooped cage up top to protect the tractor. the tines are actually stronger than I thought they would be...

Solid bar isn't as strong as you might think.

The Angry Beaver saves starving children in africa! Not really, but I really put her to work this weekend! I'm quite impressed with MY BUILD!'

got the quick attach welded on the fork cage so I could use them today.

how about a thousand plus pound all 1/4" steel work bench, loaded with tons of stuff? three sets of SBF cast iron heads on the middle shelf

Before my big lift, I thought I would try it out on a parts Kubota B6000 I had sitting out back... a good 1200lbs...

she suceeded!

so I moved on to my big project for the day... MY 21' Heavy duty trailer with my 10K chippewa 2 post lift. I've had this sitting in the back garage for about 6 months now... haven't had time to rearrange the garage to install it with all the time I've spent working out of town.
