Woods backhoe

92wrangler · May 27, 2020

Hey everyone, I have an old woods backhoe that I'm looking to find information on. I dont see a nameplate anywhere obvious, is there anyway I can find out what model it is? My issue is my dad lent it to my uncle who broke it. He replaced the pump but I believe the pump is too small and I need to rebuild some of the cylinders but I want to get some specs on it. Any help is greatly appreciated, thanks in advance.

Can you get some pictures of backhoe and sizes of cylinders?

I "would" suggest contacting Woods. I have everything to believe they are a good company and will do their best to help you out.

I'll take some pics and measurements tomorrow.
I'll try to contact them as well, hopefully they're good.

They are. One thing which I like/hate about them is that you will need to go through your dealer to order parts. It can be a PITA especially for somebody like me who shops after normal businesses are closed, but at least they're not trying to undercut the supply chain.

Not sure how to attach a picture but I took some measurements with a tape measure of the two worst cylinders.
One is 2-3/4" o.d., the piston is 1-3/16, and the length of the tube is 23-1/4"
The other one is 2-3/8" o.d., 1-1/8" piston, and the tube is 23-3/8"

What part of the backhoe are these cylinders used for? Do you see any numbers stamped into the cylinders?
What hp tractor is this on and about how old is the backhoe?
Do you have any hydraulic service shops near you? They can normally rebuild any cylinder just by disassembling and getting measurements.

Im not certain of the official names but One cylinder is for the bucket and the other is for the arm the the bucket is attached to. I'll have to look a little closer to see if any numbers are in there. I do have a good hydraulic shop near me, Unfortunately the cylinders are the easier part. I'm also concerned about the pump, it's a northern pump but it's old, I tried to run the name plate with no success and northern couldn't help me. I'll have to contact woods to find out flow specs and I may take the pump into a hydraulic shop for them to identify it. Thanks for the idea I hadn't thought about an independent hydraulic shop.

My dad purchased the backhoe with his 80's ford, around 25 horse. The backhoe is probably the same age.

I would guess a BH750 then... the same as what I have. I have the manual for it if that's any help.

Like Jstpssng said, the HP rage it could be a BH 65/75. Just for some general information go onto Woods website and looks up the specifications for a BH 65/75 .
I would definitely reach out to Woods, they would ask you to do some measuring of cylinders, arms etc and they will tell you what model it is.
As for the pump, the hydraulic shop could test that and give you the approximate specifications. When you are doing all of this work, I would change the hydraulic filter and fluid also.

If you are willing to rebuild the cylinders yourself take them apart and go to your local hydraulics shop. Take the "O" rings and seals with you, they can match them up with new. I have done the boom, crowd and bucket so far. The swing can wait and the stabilizers don't leak. I think the parts came to $10-15 for each cylinder. My BH has about 25 years of use and it has been on 3 different tractors.

I'd be careful about putting it on your Kioti (if that is what you are planning on). You really need a subframe mount hoe on that. Horsing around a 3 point BH on your Kioti can cause the rear transmission casting to fail. It's a very expensive mistake to make, Know someone who did just that. Cost him 7 grand in parts and labor. Newer tractors aren't built to absorb the strain a 3PH backhoe imparts on them.

Just be aware of that.

You may never have an issue but you get that hoe in a bit of a twist, it will break the casting.

I use my the 750 with 3pth mount which was my father's… just as I used my last "CadPlan" hoe on my old L275. I never work them hard, running barely over idle and if things start binding I back off. I've been trying to find a subframe for it as I'm not clever enough to make one. All of the dealers I talk to just want to sell me a new 'hoe... which will still need a subframe.

Tonight I wrote a letter to Woods asking them if anything is available. If not I'll probably go to a machine shop and have one built.

You can buy a lot of cabbage for the cost of a rear housing....

Got my spuds in the straw bales btw. Haven't peeped up yet but being good Maine seed potatoes, I'm sure they will soon.

I have nothing against a non subframe hoe, so long as you don't impart a twisting stress on the rear case. That twisting stress is what cracks them. Any good fabrication shop worth a plug can build one. All it really does is transfer the twist up towards the front of the tractor.

Awesome, thanks everyone for the feed back. Certainly alot of good info I'll keep in mind!

One thing you never want to do is lift the back wheels of the tractor off the ground with the BH stabilizers or move the tractor with the BH bucket, subframe or not. It puts a huge strain on the back case.

Jstpssng · Jun 2, 2020

Unfortunately, Woods does not make a subframe for my old BH750. I'm back to plan "A", which is trying to find one for my tractor which I can have modified to fit the older hoe. I don't use it enough to shell out the beans for a new one...

I modified an older BH-750-2 to fit a Late Model subframe.

Coming from an "actual BH" background I guess I assumed lifting the rear tires (slightly) was SOP. But I can see that an SCUT/CUT/UT is not designed from the ground up to have a BH on it and that even with a subframe it it not as robust as a true BH. I will try and remember that in the future, and only lift one wheel if/when needed for leveling or getting the right angle on something.

Thanks.
