Backhoe converting 757c to self contained ?

grl1961grl · Jan 23, 2019

looking for any and all info, it is going on my 1520 ford tractor. i do not have rear hyd ports. from what i read on here, its a real pain in the behind to plumb up some thing. so im looking for info on size of hyd t,ank, and gpm pump to use. my tractor spec says pump flow is 6.4 gpm. Total flow is 9.2 gpm , and pressure is 2133 psi. the spec on the 757c says operating pressure is 2000 psi. SO, if i get a pump that is roughly 7gpm, and at least 2000 psi. and say a 5 gal hyd tank. Will that work.????????? thank you for any info

I have a 757 on my New Holland TC29DA. Very nice backhoe. One hydraulic hose from it comes forward and plugs into one of the fittings associated with the loader. This is between the right front wheel and the loader frame. The other hose connects at the rear. I wonder if you could just add a fitting for the rear hose and run your hoses as needed? That seems so much better than adding a pump, reservoir and all the other stuff needed to make it work.

thank you for the info, i got it figured out now, but rear bracket for subframe , that mounts to the bottom of the rear end didnt come with my hoe attachment, wish i could find a used one, or see one up close , so i could copy it

If you don't want to order the bottom bracket, you could probably make one. It's just a simple slot across the back of the gearbox, on the bottom, that the backhoe crossmember slides into as the front pins line up with their holes. There are no pins at the rear bracket.

I can send a picture if you wish.

The trick to installing the backhoe is to drive up close and be in good alignment with it. Then hook up the lines and use the hydraulics to lift it up or tilt it as needed. Then you can back the rest of the way in. The rear three point arms must be positioned properly to clear the backhoe frame. The stabilizer feet will lift it and the bucket will tilt it. Once the rear bracket is all the way into it's slot, the tilt will move the front of the frame up or down to line up the pins. Be careful with the front hydraulic hose to keep it out of harms way and not where it will snag while driving around. Bungee cords work well for securing the front hose to the frame.

Hi Raspy, id enjoy some pics, maybe a few measurements also, i notice my front brackets arent the correct ones either, i guess ill have to fab those too. thanks for any info you could help me with. the front brackets i recieved are kinda long, and must attach up the side of the frame somewhere, and the ones i need must attach to possibly to at least two off the lower bolts on the post that stick out on each side that the loader is attached too, thanks again
