Backhoe Any info on Ford 758A Backhoe??????

RedDog · Sep 1, 2003

I am looking at this particular model hoe that is for sale. It is a Ford hoe and is on a Ford tractor,, cannot remember model of tractor.

It works well,, I tried it, and is in good shape. He wants $2000 for it. Has two buckets 12" and 15".

I'm somewhat interested in it, but would like to know more about them from someone that is in the know!!!

I'm considering trying to mount in on my Kioti or a Massey 65 gasser. I know the color wouldn't match /forums/images/graemlins/wink.gif

Thanks if anybody has any info they can relay /forums/images/graemlins/smile.gif

Don't claim to be in the know . . . but, if it works good (cylinders, rods ok etc.) for $2k I'd jump at it.

I don't know if the 758a is like the c's, but if so the subframe comes off with the hoe itself when removing it. This requires a different setup than say Bradco etc.. If it does. it requires fittings underneath (where the FEL mounts are) to guide the sub-frame into place, and, a fitting under the rear axle for the rear subframe support to slip into. Since it's mounted on the Ford now, you could see how easy it would be to transfer the mounting fittings to the MF65. Don't forget, Ford & Ferguson used to be married before they got a divorce in the late 1940's.

My suggestion would be to look at the mounting setup on the existing Ford and see how it can be transferred. Then you could see what the requirements would be. You could certainly bolt something up if you don't need a quick mount/demount. Just remember there is a lot of twisting stress on the tractor. DO NOT try to 3pt mount it. The MF65 is certainly strong enough if mounted correctly. But, don't know about the hydraulic PSI (and flow rate). If the hyrdaulics are lower pressure, or flow rate low, the thing would work ok, but just be a bit slow in operation. The 758c works VERY quick with a 9.8 GPM flow at 2600 RPM, an adequately with a lesser flow at 1900-2000 RPM. Pressure is around 2500 PSI. I don't know anything about the Kioti nor the size you might have so can't comment on that.

In short, my advice is to deal with the mounting arrangement on the "a" with how it would have to be setup on yours, how easy it would be to get/make up mounting pieces, compare hydraulic flow, etc. to see which to use it on, and go from there. If you can use it, the price is certainly right. Even with $1k into mounting issues, you'd only have $3k in it. What a deal for a BH!

W/ that smaller size hoe on your bigger tractors I'd go 3 pt and use on either one.
U should have more than enough flow for it, maybe too much flow but slow the rpms down and it will be fine.

Yeah I know the MF 65 is a sturdy tractor, but its still only about 4,000 lbs. and even a smaller hoe can put a lot of twisting stress. I personally know of tractors that were cracked with a 3pt mount BH. His probably wouldn't, but better safe than sorry if he can get a subframe mounted.

I appreciate the replies /forums/images/graemlins/smile.gif /forums/images/graemlins/smile.gif.

Yes I saw it mounted on the Ford. It has a rather weak subframe to me. Looks like about a 2" square tube going under the tractor on both sides up to the loader bracket. It has notches in it to allow it to slide into the loader subframe.

We were basically going to do away with that and make it a 3 point. I real do not think it could hurt either tractor especially the Kioti,,, in fact as stout as the hydraulics are on it, I think it could hurt the hoe!!! /forums/images/graemlins/blush.gif Both tractors have loaders on them.

BTW Grimreaper are you the guy that I would occasionally chat to on Off-Road.com???

Thanks again, RedDog Kioti DK65

You're probably right - in fact you might get away with a 3pt mount on an 8n (if the hydraulics on the tractor would lift it!) and a PTO mounted hydraulic pump to drive it, and you only dug straight in soft soil. The subframe you saw sounds like similar to current set-ups on these BHs. You didn't say what model Ford it's currently mounted on. You're correct in that this type of subframe could be stronger (what couldn't!). My only concern would be the twisting forces in certain operations. If those forces move from the BH, thru the "subframe" to the loader mounting they do not apply torque (or certainly not nearly as much) to the engine/trans/transaxle. Under certain types of work (say moving/repositioning the whole tractor with the hoe, a turning motion when prying out, say, a tree trunk, etc.) they can become pretty great. And, on the MF (I havn't ever examined the Kioti DK65 so can't say about that) the engine/trans IS the frame. If you imagine taking the tractor in both hands (front & rear) then imagine twisting it you get the idea. Personally (but I'm pretty conservative) I'd feel better about a 3pt mounted BH if it were on a 6,000-8,000 pound tractor. I wouldn't be worrying about the hydraulics as long as the pressure generated by the tractor pump is not excessive (it certainly shouldn't be). Your MF should be less than around 2500 psi and I suspect the Kioti isn't any more than that (check your manuals). The BH should have pressure relief valves which pop relieving pressure if it gets too high. In fact, if the tractor hydraulic flow were too high (and assuming the relief valves were working and set correctly) you couldn't use the BH because the relief valves would be popping off continually. The GPM (flow) can easily be adjusted by the engine RPM as Hoeman00 suggested. Remember, the flow will affect how fast it works, the pressure affects the force generated on the BH cylinders.

Again, I certainly can't guarantee you'll have any problems. Probably you won't. My suggestion was just trying to be conservative. What I can guarantee is that if you use a 3pt mounting and end up with broken studs on the engine/trans connection, or a cracked casting you'll be one pissed puppy.

Never visited off-road.com so it couldn't have been me.

Good luck with your hoe. They're sure handy.
