That is a beast!
Near the end (1993) they made them on 12th & Weshler, used to drive by every day, see them out there.
The largest backhoe I've operated was a Tracgrip with 270° slew mounted on a stretched Ford County tractor. The boom was probably similar in reach to today's 12ton excavators. The operator sat above the LH rear wheel and was able to engage forward and reverse plus steer this monstrosity. To drive on the road the boom was swung to the front an carried in a cradle. Unfortunately I can't find any photographic evidence, it was made in New Zealand by Tracgrip in Palmerston North. At that time they also made a sidemount version for drain cleaning. @D6merv no doubt you'd remember them.
I was but a snotnosed kid of 20ish, and my boss put me in the rental Case 780 to road it back to the rental yard. 15 miles, half of it right down Main Street. It was a whole 'nother rig compared to the 580 I had been on.
Are any of those shown on this FB page? NZ Road Transport and Contracting-Archives | Has anyone got any pictures of oldschool backhoes | Facebook Has anyone got any pictures of oldschool backhoes? Tracgrip rm25 ect ect... cheers in advance would love to see www.facebook.com

Unfortunately no, good try though. It was based on this tractor with the front axle about 1.5- 2m further forward https://www.mascus.ie/_next/image?url=https://dnge9sb91helb.cloudfront.net/image/product/cust/350/250/landbrukssalg/ford-county-super-654,5599_1.jpg&w=3840&q=75 That Tracweld 140 hoe was sold with an auto grade function as standard, no lazers or puters in those days .

Biggest I've seen is a John Deere 710. 25 miles from me I think it still sits outside a marble cutting business. It either doesn't run, or they park it same place & way each time. I've owned a 410, and a 410C, I don't think bigger than that is better. I've encountered a few Dynahoes. Just appearance I wonder if the ground is solid enough to support one.
A sewer project in Rutland VT had one. Seemed VERY versatile They'd take over an abandoned business parking lot in several locations around the city. I'd see this machine & a number of implements to fit it.
I remember a couple payloaders around with a backhoe attachments
We had a few in the NZ Army, Hough 65's rear steer with Wain Roy and 1 with a BLH hoe. The Wain Roy were a terrible thing to use and with so much weight on the back the loader bucket was darn near usless.
There was one on Historic 7 in Shaftsbury VT a ?A62? Ford articulated loader with a backhoe. I don't know if factory built, or home added.
