bobcat 610 aux hydraulics

[haymaker]

what kind of flow do you think you have? is it enough to run a 5 ft snowblower if i go w 3 point PTO adaptor?

My S510 has 16.1 GPM flow and barely drives the old 1812 Erskine made for bobcat that has a working rating of 11 to 21 GPM.
Snow throwers are major hydraulic pressure hogs.
That said, even though I can only get the snow moved 3 feet, it clears the path extremely well, I just have to take 2 passes, usually one in each direction to get the snow out and off of the driveway.

The aux hyd hook-ups are at the back of the machine above the rear of the engine on the right side. There will be two steel tubes capped (usually) with pipe plugs. most guys seem to like to run hyd hoses or lines to the front, down the boom, to the end of the boom and put quick couplers on for convenience. To run it with two cyls like you suggest with a blade is easy, run one hose in one end of the cylinder, then the other hose in the opposite end of the other cylinder. then, run a hose between the two remaining ports on the cylinders, one end will be the ram end of the cylinder the other end will be on the mounting (butt) end. I hope I explained that alright.

would it be easier to use a T connector so you get equal pressure to both

I just got a 610 and I'm wondering if the aux is a dual feed so i can use a grapple bucket or do i need to get a directional flow valve for it?

OK, I don't claim to be an expert on the Bobcat 610....Ahh, who am I kidding! I did a full restoration of a 1972 M610 last winter. I used it for the summer and this winter to make sure it ran well. I sold it for $18k a couple months ago! I love that machine! None of that headache causing electrical crap that was on my 773G! I have one more that I'm going to restore next winter. Anyway, that center pedal is indeed the auxiliary control. I used my grapple and plow on the machine this past year, and one peddle direction opens grapple and the other peddle direction closes the grapple. My two 610s had two different aux hydraulic types of control tubes ending at the back of the machine. I ended up running 3/8" inch lines down the left boom arm to quick connects that fit into a piece of angle iron that I drilled and welded to the boom. Attached are some photos of the auxiliary hydraulics, and of the 610 before and after. I'll take some pictures of the other aux setup in the next couple days and post them for you. Good luck

did you need to put an another control valve so you can use the plow and have it go back and forth or is that the stock system and you use the center pedal to control the side to side motion

Okay, I'll try this again. No on the control valve. That middle pedal on your machine is hooked up to a spool valve that controls the hydraulics. On the 610, there were two types of aux lines. On mine, there were two steel lines with caps at the back of the machine. I ran two 3/8" lines from those down the right lift arm too a bracket I welded to the right arm. I connected the lines to two 1/2" quick disconnects via two 1/2" bulkhead fittings mounted too the bracket. those lines powered the snow plow. I have pictures posted on page 1 of this thread that may help. Hope that helps, and I hope this post actually posts because I'm not submitting it a fourth time

I have a question on this for a snow plow application. As in the post immediately above, I have a 610 with the aux pipes capped on the passenger side (right) of the machine at the back. I ran two hoses to the front, then to each cylinder on my plow. Each tilt cylinder on the plow only has ONE port, which means it only extends, each side at a time (which forces the opposite side to retract. The middle pedal will now tilt the plow left and right, but I'm concerned about doing damage to the machine hydraulics this way, as it is using the force of one cylinder to force the other cylinder to retract. Maybe this isn't an issue and the hydraulics control valve operates that way, but it does seem like it fights itself a little bit. thoughts?

I have run the same set up as you on two different snow plows for 20 plus years on five different bobcats, and have not had any problems. If you think about it, that is basically the same thing that happens in a two port cylinder. One direction extends the cylinder by forcing fluid back into the hydraulic system, and the other direction contracts the cylinder by forcing fluid back into the hydraulic system.
