Bobcat 909 Backhoe will not work on Bobcat 773G

Dameon · Jul 14, 2014

The Bobtach plate on the 773 is larger than the receiver plate on the 909. You could possibly modify one plate or the other, but even then the "trailer hitch" arms on the 909 would have to be modified. Plus the hydraulic lines don't seem to fit the 773 (standard or high flow).
Guess I'll sell the 909 with the 743 and buy an appropriate backhoe for the 773. I've been considering one of those single cylinder (for bucket curl) backhoes. Seems like a much easier method for general use (don't have to switch seats and such). Any less obvious drawbacks?

You can modify the hoe to fit on the bobtach, i'd not modify the bobtach though.
The trailer balls are easy to mount to a 743, not so easy on the 773G, i still need to work out a hitch setup for one to my S150

Modifying the 909 was my first thought. I knew I'd be shooting myself in the foot to modify a newer Bobtach to support an older implement. Plus the hitch setup would require some fabrication. When I realized the hydraulic connectors would have to be changed, and I'd still have an implement I had to change seats back and forth, I decided to just let it go with the 743.

On the 773, it looks like you could "simply" mount the balls on the cross bar on the front of the 773 (where you step to get in). Either drill and tap or drill and weld nuts on. Again, I decided against it as the whole project would require significant work and the end result wasn't the exact outcome I wanted anyway. I have minimal backhoe needs... occassional trench in the yard or maybe a big hole to plant a tree.

why would the bobtach plate not work? thats been bobcat standard for years. the problem is the 773 has 2 tilt cylinders and they get in the way of the balls. i can't imagine the plate being the wrong size. i've moved my backhoe around with all different machines, it fit all of them (the plate that is)

I had my davis hoe on the 632 with 2 attachment points similar the trailer ball set-up except I used 3 pt hitch upper links. moved it to the new Holland with 2 tilt cylinders so now I have one trailer ball centered just below the threshold of the cab, works good so far but I liked the adjustable links better.

That's what I assumed. It doesn't look like the plate on the 909 has been modified, unless it was done well and MANY years ago, and I'm quite certain the 773 plate hasn't been modified. The top of the 773 Bobtach plate seems to fit into the top of the 909 plate correctly (angle and depth), but is too large (tall) for the plate to push flat against the face of the 909 plate. It hits the angled bottom lip (where the pin holes are) on the 909 plate which stops it from mounting flat. Obviously the pins won't lock in. As for the hydraulic connections, those could have been changed out at some point, both on the 909 and the 743... although I'm not sure why. I can try to get a picture, but it may be a while. I don't like moving the 909 around with the 773 as the poor fit causes potentially dangerous random implement drops.

The balls fit very nicely between the tilt cylinders... those aren't the problem. I could even mount balls on the "step" and they would hold the 909 nicely. The plate and the hose ends on the 909 would have to be changed or modified.

You have a 909 backhoe? I know the 709 works like a champ on the 773. As do most aftermarkets I've seen.

i have a 907 which is the same just with a shorter boom. ive moved it with a brand new s130, 763, 753, a new holland, it fit them all. the backhoe shouldnt really mount to the step on the arms,that will pull the arms around, ideally it should be attached to the chassis of the machine. could you take a picture? a standard bobtach is angled on the bottom....some times the hole spacing for the pins is different.
