My M7060 purchase and usage thread

Sorry I should have said motor not pump. Their standard unit comes with a 10 gpm motor but since my tractor will have 16 gpm flow they put a 15 gpm motor. Cost was the same.

Thanks for posting that. I think I will be taking my tractor to a local fab shop and let them fix be up some good protection.

That is a very interesting looking cutter.

Lookout ! In 2011 I bought a brand new MF2660 and a 5ft super heavy bush hog that mounted on the FEL. My dealer said all was well on paper because my tractor had 14.8gpm hydraulic output and a valve that allows me to ADD flow from the 3pt lift to that feeding the remotes. Total over 17gpm. The hog was bought specifically as a "low flow" unit such that it would supposedly run OK with 14gpm. All was rosy until I tried the cutter on real life brush, clusters of autumn olive bushes with individual stems maybe 1 to 2" thick, etc. Even when I eased into them at full engine rpm and coming down on them so the thinner parts were cut first the cutter bogged down essentially all the time. Unless you are cutting grass and weeds it was worthless. There just was NOT enough flow to have a robust cutting machine at all. If you try to live with such a configuration, make sure you use oversize lines to feed the cutter. And you are going the wrong direction to get a motor that handles 15gpm when you had a 10gpm to start with. You stood one heck of a lot better chance of driving the thing well (without it hanging up and clogging) when the motor needed a lot less flow than you think you are providing. My suspicion is that with long lines from your remotes, losses in connectors, etc. that we really do not get anywhere near the actual flow at rated pressure that the specs claim on paper.
AND a second problem I am betting you have not forseen: "One track mind hydraulics." Essentially ALL open center hydraulic systems have only one pump as the source and in truth will drive, under power, only one function at a time. Manufacturers are masterful using gravity in some axis of a device (esp. the front end loader) to fool you into thinking you are powering more than one function at a time but you are not. The result is that everytime you lift your loader frame or curl the bucket control to tilt your cutter you shut down the cutter motor (!!!) This is a pure mess which indirectly causes abrupt, gut wrenching, starts and stops when you do not want them and prevents any routine "normal" cutting like you anticipate. People do offer expensive flow diverter/divider valves that allow you to keep going on one function a little bit while shifting to doing the other function. That will end up costing you big time $. Strongly advise that you TRY ONE somewhere before you buy it. I learned the hard way that these things do not do what I thought they would.

BY the way, I traded off the hydraulic motor driven front cutter and got a PTO driven rear boom cutter which has 2 of it's own hydraulic pumps -- one for driving the cutter and one for position control. It puts out high flow to the cutter and essentially NEVER bogs down. And with 2 pumps you can change positions, angles, etc. WHILE cutting. Note also that many/most of the skid steers have much higher output hydraulic pumps for implement purposes than our farm tractors AND the loader frame on skid steers is totally independent of the implement pumps. The big front cutter I had probably works really well on someone's skid steer.

Yes, unless it's a dedicated aux hyd pump...you won't get full flow. One tractor here has a 15.4 GPM pump, but it runs steering, 3pt, remote, brakes and PTO clutch. One field I remember loosing power steering while lifting 3pt, turning and having PTO engaged. I think I'd have a PTO pump to run ANYTHING heavily Hyd driven on most utility tractors.

Wow- needed to have some saplings and brush cut on the mowing job We did to get a property ready to sell.
I mowed the large fields with a standard pto brush hog.

My nephew brought over the Bobcat S 250 skid steer with hy-flo, and rented a hydraulic brush cutter.
though it did cut some big saplings it did slow down from time to time.

I guess the flow demands can be pretty high for some of these hydraulic brush cutters.
The S 250 hy-flo pumps out about 36 gallons per minute.

Thanks for the input. Stay tuned, I will be posting results with videos. I have been following these guys and in talking to them several times, it seems to me that they have got their system down. Their standard motor of 10 gpm is designed for smaller tractors than mine with lower flow rates. With my higher flow rate we would have needed a bypass or restriction to limit the flow. I do not foresee using much other hyd uses whiles using it either. The unit will not be run from the third function since that would case instant startup and instant stop which does not work good for the motor longevity. Mine will be ran from one of my 3 rear remotes and the return will go directly to the sump to allow for free wheeling spin down. I will be picking up the unit tomorrow and taking it to my dealer and they will plump the hoses as I have specified and have it all set to go on delivery.

Well my new baby has arrived at the dealer and I got to check it out and take some pictures. Unfortunately a few of the dealer installed options did not ship with the tractor and it will be late next week before I actually get the tractor. Good news is since the delay the dealer will add and plumb up my hoses for my Lane Shark after I pick it up and deliver it to them tomorrow. Tic Tok Tick Tok.... It sure looks good though!

Also got some pictures of my attachments. They said the tiller was there but I couldn't find it, their yard is BIG.

Another cool thing is I found out I will be able to score some of there metal equipment pallet frames that can be easily modified into forever wood racks. Kubota takes all theirs back but they have others that they just dispose of, I will see how many I can make off with
