I ran my Woods 750 3pt backhoe on a 1710 with no problems. Just don't horse it around and you'll be fine.

going to pickup steel tomorrow for the subframe. wanted to play with the new toy. worked it today doing some light digging on a 3pt hookup. had to fab up a solid 3pt link as a standard adjustable length top link wont fit in the mount under the seat.

few notes on operation.
I can see how many people feel that "out of the box" the controls feel quick even at a mild 1500rpm. but within an hr or 2 i was getting the hang of it and really wanting 2 or even 3 movements at once. At which point the speed of the movements really drops when you start opening both spools simultaneously. The controls on my 2000 7500 allow a movement from both sticks at the same time. effectively sharing available gpm. IE the more you open a second spool, the progressively slower the first movement travels. Interestingly enough woods has valved the spools such that (or perhaps based on geometry of the hoe) that if you pull back on both sticks simultaneously, it will raise the boom and draw the dipper to you in the ratio that is correct to dig a flat bottom trench. I assume this was intentional as it really helps digging when all you have to do is set the bucket curl right and then yank back on both sticks.
Is that also the case for full size hoes also?
a thumb will have to be fab'd up also :-D

I've had a 7500 for 10 years now. I consider it a very well built backhoe for our size machines. The only improvement I would like to see would be dual cylinders for boom swing, instead of the single cylinder and chain.

I have a 750 mounted on a 3pt with pump. The tractor is a 34hp and this seems to be a good match. I echo the concern about the hoses at the stabilizer joints. I rarely run the BH above idle as it is rather long in the tooth.
Take care on a temporary 3pt setup. The concern is having enough strength to prevent the upper arm from crushing you into the ROPS. A way to demonstrate the forces would be to 'mentally' try and push the tractor forward by pushing the bucket away from you. My upper link (from the woods kit) has two vertical braces that lock the arms and top link into one position. For example the 3 pt control can not move anything once it is all locked up.
Enjoy!

For the factory NH subframe mount, you leave the three point arms on. I raise mine all the way up before switching the QD to backhoe. They aren't too much in the way but right next to the feet pads on the backhoe.
Don't know how alike our tractors are, but if you need a measurement or something, just ask. My hoe is off now, so I can measure parts easily.

Holy Cow! That's all I can say about what you've done here.

how can that be?
the only spot i see on the rear to "hang" the subframe off of is either
1) the axle casting which doesnt seem to have enough space with the ROPS mounted like it is
2) the lower pins were the rear of the 3pt arms connect
3) the draw bar.
so what does the rear of the sub frame hang off of for your setup?

trying to plumb the PB again... (been running off the rear remotes up till now)
1,2,3 lead to/from FEL spool control. none are marked on distribution block or on FEL spool bock. other than 1 and 3 tie into the "back" side of the spool block and 2 ties into the front of the block. (i can add pic)
4 is hard line that seems to feed the rear 3pt and remote spool pack.
5 is a hard line that ties into the bottom of the tractor casting toward the rear axle.
If i understand the system right, its one big loop utilizing open center spools for all items in the loop. So if one were to trace the path of a single drop of oil in the system it would go on this path.
from the pump on the side of the engine,
in to the "distribution" block and past the relief valve.
onto a inlet hose for the FEL up to the FEL spool
through the fel spool (if the FEL is not being operated) to the return hose
back to the distribution block (these are hoses 1,2,3 above)
onto the hardline that supplies the rear remotes/3pt
through the center of the rear remote pack, makes a 180deg turn in the end plate of the remote pack and back through the remote pack on a separate return path to the 3pt valve.
from the 3pt valve dumped into the rear casting were the filter is connected, through the filter, back through the LARGE hardline seen above to the low side of the pump.
only item in this path not covered is hardline #5 above which is the "return" path for any fluid that passes when the relief opens anytime the pressure in that loop exceeds the preset level.
SO to plumb a power beyond for any implement that needs unregulated flow for an open center spool you can interupt that loop at any place.
for instance, route the "return" from the FEL spool to the rear for (in my case) the backhoe. which means if you pull a FEL lever and backhoe lever at the same time, the backhoe will stop because flow upstream is being diverted to the FEL.
or you can interrupt the hard line that supplies the rear remotes (line 4 above) and divert it to the backhoe. thus the rear remotes wont work when the BH is connected.
or add a endplate to the remote pack stack that routes the fluid through the BH before returning it. as woods sells for there BH's (see http://www.tractorbynet.com/forums/...7b-bh-my-1720-woods-90x-install-manual-pg.jpg)
any of these points can be used to supply fluid to the powerbeyond item.
but as others have said, YOU MUST MAINTAIN THE LOOP AT ALL TIMES!
SO
if my understanding of the "auxiliary" hydraulic system is correct, can anyone help me better understand which of the 3 hoses above (1,2,3) that all lead to/from the FEL is the supply to the FEL and which is the return from the FEL.
would you have 2 supply and one return?

Ok so I just picked up a woods 7500 with a subframe to mount on the back of a TC45DA with a 16 loader.... well it appears I am missing something not sure yet.
There is 3 hoses coming of the 7500, and I have 2 remotes on the back of my NH that in the past I have only used for my log splitter....
The 3 hoses are 2 female and one male connector, the back of the NH has to female.... not enough males lol...
anyway no idea which goes which, no manual. I have the subframe mounts and will start with that I believe the previous owner said to remove the rear lift bars.... would be much easier if I could connect the hydraulics and just use the stablizers to lift the woods up to the right height and just back into it....
Not sure what to make out of the hook up instructions I saw here... so the 2 rears I have now is one loop ? like one going out, one coming back... confusing ... help could be useful
