I've been using the back blade on my tractor a little and realized that I'm not satisfied with it the way it is.
The blade itself works fine but any time I want to change the angle of the blade, I have to get off the tractor to do so.

Originally, I built this with a single spool hydraulic valve.

Awhile back, I picked up a two spool valve off a JD garden tractor.
I removed the single valve from the tractor and mounted this two spool valve in it's place.

Because the single spool valve did not have a float position, I had added this slotted bracket to the hydraulic cylinder for the 3-point hitch.

Posted Image


This allowed the 3-point to float up or down without moving the cylinder.

The pin could also be put into the hole under the slide grooves to lock the 3-point to the cylinder so it would have down pressure.
Again .. I had to get off the tractor to do that.


The two spool valve has a float position on one spool so I no longer need the slide bracket so I cut it off the cylinder.
Now I can let the 3-point float or have down pressure without having to get off the tractor.

Posted Image


I'm going to add a hydraulic cylinder to the back blade so I can rotate the blade with the other spool on the hydraulic valve.
I need to make a bracket for the hoses to mount too.
This is the start of that bracket.

Posted Image


The bracket is finished and bolted to the back of the tractor.
The hoses are run from the valve to the bracket.

Posted Image


A quick coupling fitting will go on the threaded end that is pointing back from the bracket.
The mating quick coupling fitting will go on the end of the hose that is hanging down from the bracket.
When the back blade is not on the tractor, these two fittings will be coupled together to keep the ends of both fittings clean and keep dirt out of the hydraulic system.

I got some quick coupling fittings off ebay but they haven't arrived yet.

Ray, if you could possibly do some half-A work instead of all this Grade-A stuff, it would sure make me feel better about some of my projects! LOL

Ray, I have to agree with Daniel and George. You do some excellent work. Thanks for posting the pics. Now, how can I improve what I do?

........ Thank You all for the nice comments. .........
It makes a person feel good to know that someone else likes what they have done.
I think the best part of these forums is that you can share your ideas and projects with others and you can enjoy what they have done also.

As to " how can I improve what I do ?" ..... that is a very hard question to answer .
First off ,you have to keep in mind that I've been building things since the early 1950's when I was just a kid.
So ( as with anything ) time and experience is a big factor in the quality.
I can't tell you what to do or not do without actually working right beside you but I can tell the sort of things that I think about when starting and working on a project.

Don't be in a rush. ( this project needs to be fun, not work )
I like to lay out all the parts for the job and try to visualize what I want it to look like when finished.
This way, I have an overall idea of what it's going to be and design the individual parts to put it all together as I go along.
Sometimes I make drawings but most of the time I don't.

When making the individual parts, I try to think about the strength of the part first.
Is this metal thick enough ?
Does it need gussets or bracing to keep it from moving or cracking ?

Then function.
Does it need to be welded or bolted together ?
Might I have to remove it later to get be able to work on something else ?

Then form.
When this part is finished, will it look like something that was factory made ?
Does it have smooth edges and rounded corners ?
Does the design of this part blend well with the rest of the project ?
What type of finish does it need to protect it and keep it looking good ?

Don't get in the habit of saying "that will work for now and I can fix it better later".
Take the time to make each part right now.
If something isn't going together right or just doesn't look good, don't be afraid to modify that part or even throw it away and make a new one.

These are all things that I've learned over the years ( often learned the hard way ).
Hopefully, these thought may help you in you projects.

Those are good words of wisdom. I was really thinking out loud when i posted that comment, but you have explained some things that have opened my eyes to look a little closer at what I am doing. I usually get in too much of a hurry to get it completed. And most of that comes from not having a good place to do fab work. Thanks for the insight, I'm too old to get as good as you, but I can get better.

Another awesome project Ray! Awesome words of advice also! When I build a project, the only drawings that I usually make are dimensional in nature, such as where the project will mount, or the sizes of individual parts in relation to one another. I find that it helps me to visualize (the most important part for me) what I'm doing. Sometimes I'll lay them all out in a mock up of their positions so that I can be sure to be able to get at any adjustments or maintenance items after the project is finished. I hope to one day reach your level of excellence! :worshippy1::worshippy1:
