Stumpgrinder direction

[woodlandfarms]

With only 1200lbs of lift a chipper is an interesting conversation. I am thinking about buying one of those Chinese versions and hooking a hydraulic motor up to it. A pro system is gobbled up around here, even with all the logging going on. Burning is allowed so not a lot of systems to be had.

Yeah, that stump grinder is cool. Out of my price range but cool as all heck. We have stumps left over from logging. That is the large ones. We are taking down 10 and 12" trees on occassion...

Carl,
How about something like this.

Wow that seemed to carve up that stump pretty fast. How does the PT version compare to that? Anybody got a video of their PT in action?

Notice the Grind Zero Turn needs to reverse their motor too?

 

[woodlandfarms]

So, where do you put these reversers on the PT?

 

[ponytug]

It depends on what attachments you have or will have. Not all of the PT motors can be reversed. If all of yours can be reversed, you can reroute your PTO hoses and put it on/adjacent to your dashboard, and then switch the whole thing, but do remember that when you do, your input becomes your output.

If you have both reversible and non-reversible attachments, you will need to put it on the attachment itself.

e.g. Terry mentioned that my tiller motor is not reversible, although he said that some of the older ones are. YMMV.

All the best,

Peter

If you have the ability, you can replace the one way PTO valve with a two way electric valve. If not, then you could mount an electric valve on one of the lifting arms, and take the output from the PTO valve and route it to the new 2 way electric valve. When you want forward direction, activate the normal PTO switch, and then activate the fwd switch on the reversible valve. The new switch would have a forward position, and a reverse position. I posted a manual valve in an earlier post. but the electric valve would work quite well.

JJ-

Wouldn't the valve have to be an electronic 4 way valve to switch both the pressure and the return lines simultaneously, downstream of the existing PTO solenoid?

All the best,

Peter

Yes, you are right, the picture below is similar to a valve that could be used.

I was referring to a two way valve as forward and reverse. The valve shown is a motor control valve, open center. The valve would have to match the output of your PTO. The label on the switch would be fwd, and rev. or an arrow to show direction. Post hole diggers could use something like this, if jammed, just flip the switch and reverse direction.

Taking out stumps. Some over 50" wide.... Any thoughts on this upcoming fiasco?

Don't fall into the whole!

Here is a new type cutting blade with lots of teeth. The company says that it is 50 % better than the standard cutting wheel.

I have seen these up here in JUMBO size.

Do you think this would fit the PT Stump Grinder?
