Thanks for the continued "good press" on the plow
gents.
I'm not one who knows all the answers to the tough tractor questions like some of you so if I give this plow stuff to my favorite site on the web it will still be a small contribution compared to what I've gotten from you all.
I wouldn't use it for a log splitter. Even using both sides of the double acting cylinders.
It would be weak and slow.
But there was a real nice pto driven hyd pump in the Classifieds here recently that sure had me thinking about a log splitter... Except I don't need one.
As I've said before, feel free to post my link.

Andrew..... ...on 10? Jan 03, Cannonball asked justabout the same question, do an "Archive Search" at the top of the N-Board. Read the entire thread (18) including all the links for many different pictures of snowplow installations.

Most 3-point operated front snowplows are operated by a cable and pulley scheme. Kinda rinky-dinky IMHO

N-Board contributor "ultradog" shared his homebuilt hydraulic operated snowplow design. If'n I was welder handy, I'd sure 'nuff give his design serious consideration. Its so "elegant"..... ....Dell

That's pretty neat. I might need to steal that there idea!!!!

On that setup, how do you bleed/fill the system without making a mess?

The way I did it was I filled first cylinder with the ram extended. Then attached the hose and tied the loose end up in the rafters of the garage. Took a little plastic funnel, jammed it into the open end of the hose, stood on a step ladder and kept adding oil till it was full and the air bubbles stopped coming up. I tapped it several times with a stick to knock the bubbles loose. It took several hours (while I worked on other things) for the bubbles to stop.
Then I filled the other cylinder (ram closed)brought the hose down with my thumb over it
and screwed it into the second cylinder.
I'm sure there's still a small amount of air in the system but it doesn't affect it at all.

I think maybe Ultradog is missing the boat a little by not putting together a website advertising "no pump hydraulic front plow kits" for any tractor with a three point hitch. I wonder what the cost of such a kit would be assuming a reasonable profit margin for the genius behind it?

Maybe it could be sold as a complete kit with instructions, cylinders, hoses brackets, etc or as a partial kit with proper brackets, but you purchase the cylinders locally, or third option as just a set of plans.

Wow.. Dell.. I really have to commend Ultradog on his innovativeness.... Nice idea of using the n's pump to extend the n cylinder to raise the arms to compress the outboard cylinder to extend the other cylinder....just plain simple and neat...

And if more oil volume was needed, a slightly larger diameter cylinder could be used in the rear..

Question: Can Hyd's be tapped off the pressure check port on the bottom of the tranny case?

And if so, does it bypass the n's 3pt lift? or merely parasitically 'rob' volume/pressure from it?..secondly.. is that port before the lift arm valve.. or after it.. in other words.. to develop pressure at the lower plug, does the 3pt have to be 'extended'?


Thanks

Sounder..... ...That is what I think is great about and is the beauty of ultradogs closed external hydraulic lift scheme. NO HYDRAULIC PUMP TAPPING.

Yes, there are schemes to tap your N's internal hydraulic system by using the corner pressure test port. But to make it work, you have to "chain-down" your external lift arms and you loose the use of your 3-point lift. And besides the N's internal hydraulic pump is a "weak-sister" of about 2.87 gpm and 1725 psi. And besides everytime you clomp yer cloddhoppers down on the clutch pedal, your PTO driven internal hydraulic pump stops pumping.

This why most front end loaders uses the engines front pulley mounted stinger driven external hydraulic pump. Its got the necessary hydraulic power and as long as engine is runnin, you can lift the buckett..... ....Dell

Neat idea closed system.. reminds me of the hydraulic counterpart of an electric servo setup.... just a nice idea... simple displacement..

I love this board...

Ultradogs idea of using a cylinder in the 3 pt lift would also be an excellent way of providing pressure for a log splitter.

After thinking a little more about this, since the 3 pt. doesn't power down, no pressure would be available to retract a wood splitter.

I assume that the weight of the snow plow is what extends the cylinder in the 3 pt hitch.

Just need a small counterweight on the drawbar to "motivate" the retract operation. UD's setup only uses half of the double acting cylinders so you'd need to add the additional plumbing too. I suspect there may be some problems with obtaining the stroke needed from a logsplitter with UD's setup and I suspect splitting force/cycle time would be a problem as well.
