Backhoe For real 3 point damage.

tman1020 · Apr 28, 2014

Ok. I've heard lots of rumors and have pretty much been on the sub- frame band wagon myself But I have yet to see a 3 point backhoe damage a tractor. I'm not saying it does not happen, just that under normal, heck even rough use (with outriggers) down I don't know of 1 single reliable report. I have seen on this website a frame mount factory backhoe snap a tractor in the middle. If I'm off base feel free to correct me. But I'm just wondering if all the sub-frame hype is all that it has been built up to be. Especially on today's modern tractors.

Lets try it....on your tractor!!

Too much money in my tractor to take chances for me. I hire any backhoe work done. If he hits something it is on him.

I chose the subframe mount since I operated Backhoes and Loaders professionally in my younger years and have seen (and done) damage to a machine just operating normally. I am not as rough and tough as I once was but rather safe than sorry!!

Never seen or heard of a tractor 'broke' from 3pt backhoe but I am sure they are plenty!!

My neighbor has a late 80s Kubota with a 3tp backhoe attached. It has a HARD 6000 hours on it, and other than the 2nd stage boom braking in half and being rewelded, has has yet to have any other issues

Titan is selling a brand-new three point Backhoe for like three grand delivered

For the old iron tractors, I too have seen 3 PH backhoes used for years with no damage but those old farm tractors were built out of good stuff and LOTS OF IT. I am not sure a CUT would fair as well which is where I think the sub-frames came into being. I wouldn't use a 3 PH backhoe on any of the CUT tractors but on full sized tractors of yesteryear, I wouldn't hesitate to put one on. I really haven't looked hard at the new AG tractors of today to see if they are still heavy cast iron/steel bodies and steel frames like tractor as late as 80's models but I would assume that they are since weight is needed for traction on those beast.

Wonder which one would be better would love to see how much easier it is to put on one versus the other. I've heard both can be a real pain I've also heard both can be very easy

this might be a little off subject, I have run a 3ph fransgard winch on my Kubota b7800 scut (30 hp). tractor with loader weighs around 3000lbs. winch has 7600 lbs pull capacity all on the 3ph with no sub frame, just the dozer blade/spade on the winch to anchor it. run it ALOT over the past 3 to 4 years with no visible damage yet. I am assuming that the forces of a winch are a little bit similar to a backhoe. I have always wondered since Kubota tractors are usually the lightest of the manufactures if that doesn't play to the tractors advantage when these pull forces are put on them by allowing the tractor to slide or move easier then a heavier tractor thus allowing the 3ph or tractor frame to not take all the brunt forces before something gives.

It seems the 3 pt would not be nearly as solid of a mount. I will take my frame mount any day.

I can't speak to tractors breaking in half, but I'm not sure I would call it "sub-frame hype", its engineering and physics and distribution of forces. My dealer sells two brands of tractor and will not sell a hoe unless it's sub-frame. I'm sure there are thousands of 3 point hoes out there with no issues but if those outriggers start digging in and lose footing , the forces on the 3 point are insane. Even with solid footing the force on the top link has got to be well over design .

As far as real life advantage,this is my second NH with a Bradco on a subframe and I won't hesitate to swing around and do quick light hoe work (pop a small stump, move a rock) without even dropping the outriggers and move on. Easy on and off too, and it doesn't interfere with my three point links.

As far as today's modern tractors, maybe less iron now than older stuff.

Kubota L4850

I had cracks to develop in the shuttle shift housing on this tractor. I notified Kubota and the southeastern district representative did come to my farm. The line of BS that he gave me would fill a tandem dump truck to overflowing! He said, and I quote," the reason the part failed was because I had attached an aftermarket, three point hitch backhoe (Bush Hog Brand) to the machine. If I had used a Kubota brand, it would not have happened because the Kubota brand has a sub-frame with it."
I have a front-end loader on this tractor which already has a sub-frame to the rear axles. I don't know where this fool thinks another "subframe" would attach. Incidentally, the shuttle shift housing costs almost $2000.00 plus tax, plus freight. Kubota left me "high and dry" so now I tell everyone that I know that is even thinking of buying a tractor my story and suggest buying a mule instead. At least you know what kind of manure you are going to get.

When I bought my tractor I was told usage of three point BH will void warranty. The top link anchor point is not designed to take the force that could be generated by the BH. The dealer told me that it will rip the bolts out of the housing. I looked on the subframe for BH while ago. It is bolted together with the FEL subframe.

I have a 3 point mounted backhoe and Fordson Major with sub frame and a large backhoe. The first that will break is the top link / top link bracket or mounts to the lower arms. And you are going to be mean to backhoe before it happens. Main advantage of the sub frame is that you get less movement between the tractor and back hoe

tman1020 · May 1, 2014

well i am thoroughly convinced now. i thought it was better but just did not think that it was that big of a deal. i can see where it would prevent excess movement also. i hear people say 3 point is ok if you are easy with it but i know that even if i plan to there is always going to be that time( probably most times) that a root or rock or something is being stubborn an u push it to far. the cost of the sub frame is not really the issue its the cost of the backhoes that offer subframes. which happens to be the ones that i think are of better quality. i guess that should have been enough right there but my cheapness combined with my unwilling to accept the obvious if it can save me money gets the best of me. thanks for the wake up its what i needed.
