8B Backhoe On A 4200?

[arrabil]

You guys see the exploding fireballs from Benzomatic MAPP and Propane cylinders when the tops break?

Thanks to avc8130 I finally have a mounting comparison between the stock 47 and my 8B. Looks like I might have done slightly better than Deere did.

I think the turf tires larger diameter is creating an optical illusion. If you're adept with a decent paint program, you could cut and paste the turf tires onto the rig with the R4's to get a better comparison.

I was actually measuring from the center of the axle hub. See the new pic for what I mean.

How about this then.... my mounting isn't any worse than Deere's....

I agree that the different diameter of the turfs vs. the R4s make it hard
to compare the mounts visually. Of course, the 47 is much different than
the 8B, too.

It DOES look like your departure angle is better for the 8.

It looks good, and it works, so in the end that's all that matters.

Good job.

More of a rhetorical question cause there is soon going to be an 8B on my 4200. Picked it up Wednesday. And I removed all the brackets from the 970 tractor it came from too. The "leak" is from the fluid coming out of the connecting hoses. Too late to reposition them not to do that.

The 8B specs out in between the 47 and 48 weight and strength wise while utilizing the same hydraulic specs. This is unlike the 7 hoe which take less hydraulic pressure to operate and is much weaker than the equivalent digging depth 47.

I figure since the 42/43/4400 frame can handle the weight of the 48 hoe I can install a few hundred pound lighter hoe that still digs deeper than the 47 and costs a good bit less on the used market. And since I need to build a subframe for it anyway, I might as well have a hoe that came with half the subframe already there.

I'm probably gonna keep the brackets in case I need/want to sell the thing, but the plan is to copy the mounting design so that the hoe uses the same JDQA method as originally intended, and blend the design with dfkrug's subframe mount for his 4300.

You can also see how we pulled the UHaul trailer out from under the backhoe by strapping it to my offroader's bumper.

Hi Arrabil

I just picked up an 8B and looking to slide it under my 4410

Any tips from your project years back?

I have the underbelly subframe for the 8b but not sure if the other brackets are there. havent picked up yet.

Any thoughts would be appreciated.

p.s. Swapping the engine so will have some good parts from the old engine. Its spitting oil so wont know whats wrong till i split it apart but have a good engine i am gonna drop into it.

I figure you resolved your engine issue from 12 years ago but figured i would mention.

Any help appreciated.

Thanks

Just an FYI, this thread is a decade old and the OP (arrabil) hasn't posted since 2013...
Too bad, nice guy...

Folks I have a JD 1070 and an 8B Backhoe. I need the attaching hardware, all 4 brackets and any other parts you may be willing to sell. I am in Nevada so finding parts here is a little tuff. If any of you know any one that would be willing to sell me brackets, please let me know. tom@looknupguides.com (530) 249-4979
