    Go to ETA and check out the rotary brooms for compact tractors. They are not cheap and you can get a hyd power setup for additional money (also not cheap).

    I must agree with Coyote Machine and recommend using a skidsteer for the hyd PHD. You would be
    ahead and no chance of damageing your DK.

    Just my worth.

    Don't get the hydraulic motor phd on tractors. Just get a pto driven one with a down pressure cylinder. Why force it.

    I'm sorry, but it is funny to me for you to say to use hydraulic down pressure, and then say "why force it". When that is exactly what you would be doing, is forcing it. The hydraulic down pressure kits work quite well by the way.

    The reason Kioti Manual says to NOT run hydraulic motor is; there is no oil cooler in the loader/remote/3pt circuit. The smaller of the 2 gear pumps sends oil through the steering unit, through the cooler, then back to hydrostatic pump for charge pressure, then gets dumped back into the rear differential to mix with the loader circuit oil. Running a "continous flow under pressure" of the loader/rear remote circuit could cause overheating and damage the pumps on HST. An hydraulic PHD is more of an intermittent operation, unless it is in very hard ground and takes several minutes to dig a hole.
    Running a hydraulic broom to sweep snow could be hazardous to the system, even though, this would be in cold weather. If I was to do this, I would run 1/2" hoses full length to boom to mimimize pressure drop and put an oil cooler in the return line coming back from the broom.

    It only takes me about 30 seconds to dig a post hole with my hydraulic Danuser. I don't even worry about heating the fluid. I do have fairly ideal soil, however.

    Excellent description of potential pitfalls! Does your PH Auger run off 3PH or loader on your bobcat?

    I have a ROTOMEC PHD sold by John Deere. I am wondering if there is a down force kit for this unit? I haven't seen one. The design is generally different than other PHD's that I have seen with a down force system.

    According to the documents on ROTOMEC's web site, they do. See the links for PDF files on this page: ROTOMEC USA - Products - Rotary tillers

That is not the same as assuring one that it will work with YOUR tractor and it's inherent fluid flow, designed to run with very specific implements, NONE of which are running hydraulic pumps as part of the implement's fluid loop.
    No, I'm not convinced of anything. I started a thread 8 months ago to get feedback on building a hydraulic broom and I'm only relaying what I'm told by my dealer regarding the PHD. My dealer matches a hydraulic PHD to my Kioti tractor, EA sells them with no complaints and we have another TBN member saying he loves his hydraulic PHD and it works well. My own sense tells me the intermittent use of a PHD is not going to be a huge issue and I wouldn't have an issue using one that my dealer assures me is a good match for my tractor. For now it's still under warranty and they can't really claim abuse if they gave me the implement.

    Just seems like you'd be back in the same dilemma with it as the front mounted auger.
    No, I'm already switching between the blower and zamboni attachments on the back. The idea is to have 100 gallons of hot water in the zamboni, run around and sweep the ice and then flood it. I have no use for a broom in the summer months.

    Thanks. As I said, I have started a thread about building a hydraulic broom, but this issue has never come up. I didn't realize the manual says not to run a hydraulic motor. I will discuss this with my dealer if I decide to go forward with it and I like your idea of a in-line cooler. I might also butcher my existing walk behind broom and use the engine on the attachment. In the end, this might be the easiest, safest and cheapest way to get it done.

    As I posted earlier, my hydraulic auger is not a problem since the use is intermittent as mentioned. The motor has low inertial momentum (term?) so the motor doesn't "keep going" once I remove the power. Also, I am using a standard spool valve so I am jot "slamming" the port closed. By the time I center the spool the auger has stopped. If I had either a continuous-use motor or a high inertia motor, I would think differently.
