I have a b6100 and I want to hook up a hyd cylinder for my new snow blower I bought. I have only one port on my power beyond block , I have a open circuit valve I know I have to get back to the pressure line do I cut and install a tee or is there a block adapter that goes at the banjo nut where the pressure line goes back to the tranny or get the power beyond block w/ two ports. What hyd fluid do I use ( TDH ?? ) one more question is it common that a Kubota b2510 blower is very loud, I oiled all bearings , turned by hand easily. THANKS

Re: b6100 hydraulic probblems
Does your hydraulic cylinder have one hose or two? If you are only wanting to lift and lower a snowblower you can use the three point hitch valve that is now on your tractor. ( this is true for most Kubota's I use the tph valve to lift the snowblower on my BX)

It is double acting cylinder, if I did have a single acting where on the 3ph can I connect a hyd line .
Did you buy the valve for the blower or did it come with it?
It may have the ability to convert it to a power beyond valve. The conversion is usually a special plug screwed into the valve body.
The power beyond feature is also called high pressure carry over.
With the PB feature, you could direct hydraulic power to the new valve and then through its power beyond feature, to other devices downstream of the new valve.
A few pictures would help.
Re your blower noise question, it ,may be that you are rotating it far too fast.
From what I see on Messicks.com, it appears your blower is a single stage unit so no fan just a place on the auger to force the snow up the chute.
Do you have any spec's on the unit?
How are you driving it?

Dave the valve that came with it, to me is junk, I build hyd systems for my bigger trucks, this system is new to me, trying to figure this out. I have smaller hyd valves that will do any operation in my garage. There was nothing on this tractor as in hyd's, all I found was a port on my pb block trying to find a place to return the the out flow hose. Thanks
Most B6100's that I have seen have a selector valve on the hydraulic lift right under the front edge of the seat with a fitting right beside it. This is for operating a single acting cylinder. If you remove the fitting and install a hose to a cylinder there you can use the TPH lever to raise and lower a single acting cylinder. you use the selector valve to select whether the TPH operates OR the cylinder does. You could install a vent with a filter in the rod end of your cylinder to convert it into a single acting cylinder. This works good on snowblowers because you don't usually want down pressure on them anyway!
Even if that sel;ector is missing as on later model tractors there is a "test port" on the head end of the TPH cylinder thay you can attach a hose to for operating a single acting cylinder. on some models it might be necessary to mechanically block the three point hitch so it cannot come to the top and cancel the valve.
This is the simplest and best way to operate a snowblower in my opinion!
I do it that way on my BX24 because it frees up my loader valve to operate my chute rotator AND my chute deflector!

Some people think the selector under the front of the seat is for locking the TPH and it does serve that purpose but the intended function is to operate a single acting cylinder.... Back in the old days many front end loaders were operated from that valve, they had single acting boom cylinders and a simple mechanical trip to dump the bucket! I loaded 100's of manure spreader loads of manure with such a system and it worked great.
I still would like to see pictures of the blower to see if I am correct in it being single stage. I have not heard of single stage blowers on Kubota's of your vintage.
Does your valve have a float position? Many operators find that without a float position they loose steering as the blower starts exerting forces to lift the front tires. Eserv's comments about single acting cylinders follow the float position goals. You also gain the ability to have pressure say for when you want to scrape.
This is an image from a B7100 hydraulic block that enables multiple control valves to be powered. It was bolted on top of the existing block. It was a Kubota add on. If it does not help I will look on a B7100 to see where the return line from the two additional spool valves got flow back into the transmission

A Kubota B2510 is a single action snowblower ( Properly called a snow thrower) That's all we had back in those days!

What rpm did they run at?
I don't think the B6100 would have had a mid pto but rather front implements came off the front of the engine pulley down to a shaft with V belts.
Am I correct in this recollection?
Dave
I don't know if they all had mid pto but my service manual clearly shows one and doesn't say whether it was optional or not.
Unless the tractor is HST the belt drive off the front of the engine would be better anyway. A snowblower is no fun to use if it stops when you depress the clutch to stop tractor movement. The gear drive Kubota's hardly ever had live pto's in those days

This site is great, love all the help THANKS eserv I did think of doing that idea of venting down pressure on cylinder , I have nice little vent filters in the garage, I don't have a valve on that 3ph port , so if I hook up to that port ( under the seat ) I should put a valve or quick coupler in line and shut when not using blower , right. Dave the blower I bought ( b2510 ) is a single stage blower and I was going to use a valve with float , which I have on my shelf. I just think the blower is loud, may be its me , we had snow yesterday and tried the blower w/ a turnbuckle in place of cylinder today, works great just have to get my hyd's installed, THANKS for the help.
Yes, I would put a quick coupler on there. And in your case you need to vent the base of the cylinder and hook the hose to the rod end because of the way the cylinder is mounted. If you go that route, make sure the vent is such that it can never draw in moisture.
Because of the speed the rotor it turning and the fact that it is mostly open those blowers do make a lot of noise!

Scraping with a snowblower is mostly futile anyway because the blower is riding on wear shoes. ( at least it should be LOL)I still would like to see pictures of the blower to see if I am correct in it being single stage. I have not heard of single stage blowers on Kubota's of your vintage.

I have a 2510 blower for my B5100D. Yes, it is obnoxiously loud. As suggested by others, I use the 3-pt with a cable to lift and lower the blower and my blade (which I honestly think works better than the blower most of the time). If you want to use a double-acting cylinder on these machines, take the pressure line off of the valve under the seat, run it to your control valve, and run the return into the fill cap on top of the trans. That's the way I was told to do it.
Just to clarify in case anyone reads this in the future. The B5100 and B6100 gear shift tractors had no mid PTO, but an electric clutch PTO run directly off the front of the engine crankshaft which then drove a belt. This was used to run the mower decks as well.
