Hydo Pole Saw

[Couple of Achers]

Provideing the flow of the tractor is adequate, can you run a hydraulic pole saw off a full detent remote valve without any further valving? In other words, is all the necessary valving contained within the pole saw?

Which hydraulic pole saw do you have?

Look closely at the saw, it should have something stamped on the housing to indicate the type. I believe the pressure is about 1500 psi. I also have the hyd pruner.

Some of the hydraulic chainsaws, are CC, and some of the newer ones had a switch to switch between OC, and CC .

I have a hydraulic backpack for one of my pole saws. It dose not have a cooler for the fluid on it, so I am thinking that it is CC. I also believe the bucket trucks are CC, but am not positive.

Operating Pressure: 1,000-2,000 psi

Thanks for your answers guys, but I am becoming aware that when it comes to hydraulics, there can be no yes or no answer. Who knew it could be so complicated? Guys like me aren't smart enough to even ask the questions correctly so we assume too much. Let me try again. If I wanted to buy a hydro pole saw and run it off a set of rear couplers. I am assuming (see there I go again) you need to run it off a full detent valve, not a regular valve. If I am wrong, let me know and I'll stop here.........

If I am assuming correctly, then wouldn't it then also be true that I would need a pole saw the allowed the oil to flow back to the tractor even when I didn't have the chain spinning. If so, then isn't that what is called an open center?

In my mind, that is the only way it would work. Now remember, that's my mind.

You mentioned a closed center pole saw. Wouldn't the tractor hydraulics constantly be in relief mode then until you spun the chain?

It's all too confusing for us non-hydrolites.

Your patience is appreciated.

As you figured out, there are two types of hydraulic systems, OC and CC. A lot of industrial equipment, like the bucket truck tree companies use are CC-so the pole saws are also. Your machine is OC, so you would need a saw that could be used on OC systems.

Yes.

Yes. That is why you need to make sure it can be used with OC systems.

Clear as mud?

I thought I had it figured out. Sometimes I just need to hear it in simple terms to get it to sink in. Thanks.

Well, if you need simple then I am your man

Like I said before, the newer pole saws can be switched between OC and CC. So the answer is yes you can use a pole chainsaw, hand held hyd chainsaw, hyd pruner, spinning 10 in disk, etc.

I have even thought about locking down the trigger, and activating the CC saw from an OC type circuit using remote valve. Might work.


I have 6 of the hyd pruners, that will cut limbs 2.25 in thick. Like this one below.

If you are going to be using the hyd pole saws, then I would recommend adjusting the tractor remote valve relief setting to about 1500 psi.

Nice saws, JJ. I have never considered hydraulic saws for this application;
perhaps I should. I have tried the best of the Stihls, and it was SOOO
heavy, esp in a bucket lift that was waving all over.

Looks like the chain saw in the photo can do at least 6-inch, yes?

 

[J_J]

Yes, it should do 6 in very well. A trick so it doesn't peal the bark, it to cut a little on the bottom first. The hand type hyd chain saw will take just about whatever bar and chain you put on it. That is the one I was going to put on a boom pole and be able to trim up about 20 to 25 ft. Here is a picture.
