Point me in the right direction (Please)

Hey guys,

I have been tinkering on and off with building a tree snipper (for about 2 years now)

I saw a thread on here a few weeks ago about using the PB from the loader instead of buying the block from kubota. I cant find it again. I was going to buy the parts from kubota to install the rear remote on my B1700. I am a cartoon kind of guy so I will need pictures. Or just point me to the thread. I will continue looking but havent had any luck yet.
More information is better for you guys so bear with me. I have the Snipper built with some minor tweaks to go yet. I have a Cross, open center, valve. I will only be useing one cylinder for now. Later I hope to add TNT. I need plumbing advice.

Thanks in advance for your help

Jamie

Show me some pictures and exactly what you want to do, and I will try and help. Do you want to go electric or manual valve. If you have the PB, and the valve, then you are almost there. Where to mount may be a problem, that is why I suggested a 12v solenoid valve. You could place the toggle switch anywhere. Did you want to tilt it, or turn it 90 degrees, or anything in between.

I already have the valve. So I may stick with that for now. I wish I had known exactly how the solenoid valves worked I would have used one. I still may take the valve I have back and order a 12V valve. I am not to far along to change. I only need one valve as of right now but later when I add TNT it another valve sure would come in handy. I thought maybe a set of QD to switch between the TNT and whatever I am using on the front....ie snipper, grapple ect.

OK J_J what valve would you recomend sir? The more I think about it the more I like the idea. Instead of a couple of mounting options there are quite a few more possibilities. I would like to save as much money as possible. (I guess everyone says that)

I am almost positive it is the PB comming off the LA301 loader valve to the rear of the machine. I didnt get a chance to even look at the tractor today. I am on a night hitch and caught flight late or rather early this morning. Didnt feel like doing much today. I will get some pictures as soon as I can though

Here is the 12v solenoid valve, and you will need a one station sub plate on the right side of the page to connect things together, and some terminal connectors for the wire. If you have a joystick valve arrangement, you could make a hollowed out ball with a toggle switch inside, or purchase one. If you are thinking about another cylinder, they make a 1 or 2 or 3 station sub plate to mount the solenoid valves. The sub plate is where you hook up the hoses. This valve will handle up to 10.5 GPM

Thanks for the info. If I use the solenoid valve my thinking is I could tie it into the curl. Then I would be able to control my attachment or the TNT with the joystick for the loader. It could be feathered and wouldnt be full open or closed. Am I on the right track?

jamtuc- I did a similar thing when I built my grapple, but used a different selector valve. Here's the thread: http://www.tractorbynet.com/forums/build-yourself/143329-unveiling-willl-da-beast-ii-2.html Some reason I can't post the link Go to Supply Center, It' part # 9-1782
The valve is pricey, but no sub-plate. J_J could answer the advantages of either. The valve mounts on my loader tower, is plumbed into my bucket curl circuit. Activated by a button on the joystick. Pressing the button is a positive change from one circuit to the other, but you can the 'feather' with the joystick, right (open) left Close grapple. I ran hoses out the right lift arms to two quick disconnects. Pics tell the story. Click on them to enlarge. Good Luck! ~Scotty

The single solenoid valve and sub plate would take the fluid from the PB port, and simply give open and close.

You would need two solenoid valves and sub plates to tie it into the curl cyl, and the tree snipper. The switches would be wired different, and now , the cost would be doubled.

Yes, you could use the valve that Scotty used. It diverts fluid that would normally go to the curl cylinder, and sends it to the grapple, allowing you to feather. Like Scotty said, it is pricey.

I decided after looking at all the pricing and the need to actually start removing trees that I will stick with the parts I have on hand.
The valve I plan on installing has a 3/4 inlet and outlet. The loader valve is a 3/8ths (99% sure on this) the working ports are 1/2 inch.
The next question is. Or should I say series of questions. What size hoses do I need to go with? Can I go from 3/8ths to lets say 1/2 inch back down to 3/8ths. Will I have problems with the pressure changes, speed of system, or any other problems. I would like to go with one size hose if possible.
