Backhoe Size?

[straightsix240]

Hey everybody, I'm new here. I've got a Kubota L3750 4wheel drive tractor with a front end loader on it. I've got the opportunity to buy a Bush Hog brand backhoe, model 860 H. Would this backhoe go on this tractor? It is a 3 pt hitch mount, but it's on a Ford 4610 right now and I wasn't sure if it wasn't a little big for my Kubota. The backhoe has a 16" bucket on it right now.

Thanks!

My Bush Hog brochure lists the BH850, and the current 8.5-ft hoe is called
the 85CBH. I don't know of any "860" hoe from BH.

If it is like the BH850, I would be inclined to think you can mount it safely to your
L3750 with a good subframe. It calls for 6-8 GPM/2400psi hydraulics.

It should be fine.

:welcome: to TBN! That hoe requires 5-7 gpm, 2,200 psi, weight less bucket 1,095 lbs direct from manual found on ebay right now.

I would probably get a frame mount from the dealer for it. Thats a lot of weight on the hitch, especially when digging.

Thanks guys! The Bush Hog 860 H is a three point hitch mount, and it has it's own hydraulic pump (PTO powered). I don't know exactly what year the backhoe is from, but it's on a Ford 4610 tractor right now, that is probably an '88 to '90 model, so the backhoe would be similar age. I don't know what the lady is asking yet, so that's the biggest unknown.

But if I have to have a sub-frame mount then this won't be practical for the Kubota as I need the 3 pt for several other implements... Any other ideas?

Thanks again.

The lady also has a Goossen Chipper/Shredder, PTO powered. Anyone ever use one of these; how powerful are they, how do they hold up, etc.?

David - The subframes made for Kubota tractors like the L3750, for mounting Kubota or Bradco backhoes, do not interfere with 3-point hitch implements. Even if you don't find one of those sub-frames (getting rare these days) the L3750 has a strong enough chassis to handle a 3-point backhoe if operated within reason. The L3750 is one of the older Kubotas with big bones - very rugged. It has a 2-speed pto as well which will do a nice job with the hydraulic pump on this bh.

I have been thinking of a small backhoe for my BX2230.Does anyone know of a hoe that would fit or will I have to get a bigger tractor? It would sure beat a bar and shovel:laughing:

Thanks rbargeron. So the subframe is just something bolted onto the tractor frame that you hook the backhoe to when you put it on the 3 pt hitch? Sorry for being dense, I'm new to these 3 pt backhoes.

The L3750 does indeed seem to be a rugged old beast. The hydraulic pump went out a few months ago, but with a new pump the old girl can pick up 2400 lbs on the front end loader with pallet forks!!

Where's a good place to hunt for a sub frame?

Check with the manufacturer of the bh, or if you're up for a welding project there's several threads on making subframes for backhoes. Other sources might be eBay.

If the backhoe is a subframe type, it connects directly to the subframe and does not use the 3-point hitch arms or top link. If it is a 3-point type, it attaches to the arms & top link. The nice thing about the 3-point hitch is it is universal. The drawback is it isn't as strong & rigid.

BH subframes are reinforcing frames bolted under the tractor - they usually connect in several places to the rear axles, bell housing, front loader frame, etc. Backhoes and tractors are all different so backhoe subframes are REALLY all different. The tractor is the harder thing to match. Once you have a frame that fits your tractor model, getting the backhoe to fit it is the easier part.

Short of custom-making one, the best place to find a subframe to fit the L3750 might be a tractor recycler or a large dealer's attachment/parts yard, Craigslist, eBay, etc.. You'd be looking for anything that is intended for a L3350, L3750, L4150, L4350, L4850, or L5450.

Today's backhoe manufacturers offer subframes for current models but fitting to older stuff is hit-or-miss and spendy. For the L3750 I'd try it without a subframe and see how you like it. A lot of digging has been done by 3-point backhoes. Have fun - Dick B

The Goosen is a good unit! There is a backhoe completing kit for the bush hog backhoe that is current for that model tractor. What has been said about the backhoe's not having rigid frames is true of tractors of that vintage not having frames but connecting to the three point hitch. It was right after tht that they started putting frames on them.

Thanks for all the info guys! I'm busy reading that backhoe thread; lot's of good info!

Your (rbargeron) description helps me a lot just understanding how these things work. This backhoe is really the first one I've ever seen, and I was looking with a flashlight in an old dark barn!

Glad to hear the Goossen is a good unit. We'll see about this equipment when the lady prices it...

When buying a used hoe attachment, condition and location are everything. For
the past several years, I have seen decent units going for only a couple $K or
less in my area.

It is perhaps useful to note that virtually all hoe attachments from the major
non-OEM vendors (Woods, Bradco, BushHog, Rhino, etc) were offered with
a selection of subframes and a 3-pt option. The 3-pt option was so the hoe
could be sold to anyone with a CAT 1 3-pt hitch. The 3-pt option or
the subframe just bolts onto the back of the hoe and either can be easily
removed if you want to go the other way.

The only common hoe attachment I can think of that came ONLY with a
3-pt connection was the Kubota 4672/4690 series. If you made a
subframe to mount one of those, you would have to cut the 3-pt parts off.

Sadly, I have just sold my last tractor that I made a subframe for, and I
am soon to have only one tractor to use around here.

Good to know dfkrug. Thanks!

Down to one tractor, what a shame! 'Grin'
