I am wondering if anyone has used both of these models and can comment on one vs the other as regards power. I have ordered the 47 (actually the now 447) and am concerned that I should have gone w/ the 48. I am not planning to do anything too demanding, just some drainage work and the occassional stump removal. Will I be ok with the 47 or should I change my order. Thanks (once again)

If the tractor you have will accommodate a 48/448 get it.
I have the 48 and love it, My neighbor had a 4200 with a 47 hoe and had many problems trying to remove stumps. I had tried it a few times and it doesn't have anywhere near the power of the 48.

Your tractors hydraulic capability has a lot to do with how much power the backhoe has. I have a 47 and stump with it and it does everything I need. You do NOT want to go too big for your tractor. My JD dealer will sell a 48 hoe on the mid size JD compacts but they charge a few hundred extra to reinforce those areas on the tractor that are prone to breakage. I went with the hoe that will be less likely to overstress the machine and have no complaints whatsoever. ....

Run, do not walk, back to the dealer and change the order to the 48. I just went through this and did exactly the same thing...ordered the 447 and then started second guessing myself. I changed the order for the wrong reason...aesthetics. I have the old style loader (430) and wanted the hoe that matched. The 300CX FEL and 447 BH are all curvy and zoomy looking. The 430 and 48 are all no nonsense straight lines. When I picked my tractor up, there was a 447 on a 4310 right next to my 4410/48. I could not believe how much the 447 looked like a toy and how much the 48 looked like a real backhoe. I have been pulling coffee table sized rocks out of my yard in doing some trenching...I would pay to see a 447 tackle the same rocks.

On a side note, I am absolutely amazed at how easy the hoe is to take off and put on. I did it the first time in about 5 minutes with help. After about 4 off and on cycles, I can now do it in about a minute and a half by myself.

As to not over-taxing your tractor, if JD says a 4310 can handle a 48, I would believe them. The way the frame mount bolts to the machine, I can't imagine doing any damage to the tractor. ....

Talk to a JD dealer who has seen the damage with the 48 hoe vs. the 47. Talk to the guys in the shop, not just the salesman. Ask them about fatigued rim flanges and wallowed out holes. My dealer has seen and fixed these problems, and that is why they won't mount a 48 hoe on a 4310 without welding on additional support. They don't do that on the larger framed machines. Maybe they are being conservative - I'd be interested in what other dealers say about it. ....

I'll let you know what my dealer says. I'll be visiting him this weekend. Based on what I've read so far, I'm leaning towards the 48 vs the 447. All the JD literature I've read indicates the 48 can be mounted on a 4310. I haven't found any caveats indicating modifications were necessary. Most manufacturers will not recommend combinations that could cause an incompatibility issue with standard stock items. ....

I have the new 448 Backhoe which I believe replaces the 48. I works great with my 4520. I have not used any others to compare. Also the 448 series will dig a foot deeper than the 447. ....

I couldn't wait until the weekend to see my JD dealer, so I gave him a call. He didn't even recommend the JD BH. He preferred a 3rd party Taylorway(sp?) brand (6 1/2' reach 18" bucket). Mentioned he liked the PTO hydraulic pump on the Taylorway vs the JD set up. Anyone have any comments on the Taylorway? ....

He proabably loves the profit margin also. The one you describe is not even in the same class as the 47 or 48.

I have seen no stresses in any wheels or any place else on my hoe or tractor. I have over 1000 hrs on 4400 and 150+ on 48 hoe. Common sense and a good maintenance program go a long way toward reducing problems.

I've seen lots of 48 hoes around here and only a couple of 47's. I have not heard of any issues locally. But have heard a couple on here. I also drive by the local JD dealer 3-4 times a day and hardly ever see any little tractors in there being worked on. ....

I've never saw a 47 hoe, so I can't judge them. My 48 hoe came on a 4300 and is now on a 4310. I have no idea how many hours of use the hoe has had but it does an amazing amount of work for it's size and I've never had any of the problems mentioned here. Frank. ....

I ended up with the 48 hoe for my 4310. I have not used it a lot yet as my major projects are a month or so out. I am wondering if If the hoe is underpowered. I have read others say they use the hoe to move the tractor forward rather than get off and drive it forward. I don't plan on using this method, but my 48 is not able to lift the back of the tractor in this manner. Is it normal that it can't? ....

When I was looking for a backhoe my dealer had both 47 and 48 in stock. The sales guy, a career man who handled their government sales too, told me they had some history of trouble using 48 hoes on the mid-size frame and they always welded additional support when installing them. The dealer is very reputable and would have sold me either one. So, that's all I know about it. Maybe issues with the 48 have been mostly due to new operators who overstress the equipment or maybe my dealer is extra conservative. The 47 has been fine for me, no complaints at all. It's easy to bang the tractor around pretty good even with the 47. Frankly, unless you use the hoe to make a living I can't see the big advantage to the 48. If the extra reach saves you a few hours a year because you have to move the tractor less you will pay a lot of money for the time saved. If you use it commercially it's easier to justify. ....

Do yo have any thoughts on the 447 vs the Taylorway that my JD dealer recommended? He quoted me $6500 for the Taylorway but I found it on the internet for $4300. He didn't quote me a price for the 447. ....

Sorry, don't know anything about the Taylorway. There are all sorts of backhoes on the market, from homemade junk to high quality stuff. Myself, I like to stick to the name brands. My preference would be to get the JD hoe for several reasons. First, will an aftermarket brand affect the tractor warranty if there's a problem? If the dealer says "no", get it in writing. Second, the aftermarket hoe might be a hindrance in resale. I would tend to shy away from buying a used machine that had a third party hoe. Third, how long has Taylorway been around? Will they have parts and support for your hoe in a year or five? I think you will get back the extra money paid for the JD hoe on resale. All my opinion. ....

By the way, I don't mean to impune the craftsmanship of some guys who have made very nice backhoes in their shops. It is possible to make very high quality implements if one has the skills. I'm envious of those who have the equipment and skills to do that. ....

Like Ken I am very happy with the 47 backhoe. The dealer told me the 48 would require another "plate" to be added - whatever he meant by that. Being a homeowner I have accomplished everything I need to do with the 47. ....

Ahhh the power of the internet! I was able to gather a significant amount of information from the JD website which should answer a lot of the questions in this thread. According to the JD website, a Heavy Duty Sub Frame Kit (LVB24795) is required for 447 BH in rental and commercial applications and recommended for all applications. This HDSFK is required for the 48 BH regardless of the application. The 447 BH also requires a Power Beyond Kit (LVB25085) to get the hydraulics to the BH. Also, a bucket larger than 9” will cost you. (Maybe that’s why the 447 looked less than manly next to a 48 with a larger standard bucket.) ....

I have a 13 inch bucket which seems to be a pretty good compromise. A little to big for some trenching, post hole digging, ground with shale - but good for other general work like planting large trees, shrubs, digging up stone walls, general excavation. ....

I agree that the 13" is a good compromise size. For me it's just a bit big when digging stumps but it was a little small when excavating for a retaining wall. ....
