Backhoe Adding backhoe to TC45D

[skinnr]

Thanks for everyones help on this. I got the backhoe mounted and opperating yesterday. I will add some pics soon so the next guy will have something to look at. The only thing now is running the darm thing. It does not seem to want to let me multi function the controls. If I try to roll the bucket and boom up / or jib in it does not seem to want to do that. Kinda hard to dig a trench one function at a time. Any ideas or am I just use to running my big excavators?

I have TC33D and with my backhoe it's very slow if you're trying to perfume 2 operations at the same time. I believe it may have to due with the lower flow rate of the hydraulic fluid on our compact tractors.

You have only one hyd pump, while excavators and TLBs have at least
two. This means that if you want to run 2 circuits at once, you have
to feather the controls. It is a different skill, but something you will
pick up with practice. Also, you can slow down the boom swing by
using 2 circuits at once.

I think your right, it will just take practice I guess. I ordered a shim kit for the relief valve and that seemed to help a little bit. It just seems like the valves are so tight that it hardly lets a guy even feather it. I don't think I want to shim it much more since I don't have a way to test the pressure. Last thing I want to do is blow something up. I have noticed some improvement in the FEL controls letting me multi function, but it still seems somewhat slow. Maybe more shim. I have done all the filters and fluid so I don't think that is the problem.

I would look into adding a subframe to your mounting system. I spoke to the Bradco people about a mount for my 55 and they wouldn't recommend or waranty it. They did not produce a subframe system for this mount and did not feel it would hold up properly. My 611 was a skid steer mount and I believe both tractor and hoe mount plus shipping was in the 3500 range... equal to the back hoe price. I am running off an open circuit and have plenty of oil flow .

Yup its on a subframe with the quick attach. It is actually a really sweet set up and fast and easy to connect. It just seems like ther is not enough flow. The backhoe it brand spankin new so I am wondering if it is just so tight and the valves are sticky. Still working through it.

I adjusted the shim pack in the relief valve as well. I used a pressure gauge plugged into one of my remotes to check the pressure and make sure that I have the right number of shims.

i have the same experience...

My 16 LA front end loader will curl and lift at the same time. My 757-C backhoe will curl, crowd, and lift at the same time, RPM's must be above 2300. It does take a little practice. You need a soft touch like handling eggs.

Well I talked to the engineers at Bradco / Paladin equipment the other day. After a few different calls back and forth they basically told me that I have been spoiled with my excavator. They stated that the functions will act the same weather it is running at 1500 RPM or 2500 RPM. Although the BH is rated for 8-12 GPM they stated it will perform all the functions the same no matter what GPM your running. So if I am running 9 gpm or 12 gpm the actions will be the same. The GPM will affect the force that the BH is producing not the smoothness of the controls. Basically they said I need to feather the controls more. So with that said who wants to buy a brand new Bradco BH. HAHA. I guess it will be fine for small projects but for the more serious big boy projects I will have to get the big boy hoe out.
