TYM T574 ok at higher altitude?

[ericm979]

I run my 3725 at 2000 rpm when using the Branson BH76 backhoe. Rated RPM is 2500 but it doesn't need that much flow, at least for me.

I've heard enough bad stories about 3pt hoes damaging tractors to want to stick with a subframe model.

Kukje doesn't have an EGR for tier 4 models, just the DOC+DPF and data recorder.

Yes, add-on backhoes are tough on tractors.
I don't know if any of the Tier 4 models have an EGR. Many of the Interim Tier 4 models did.

I think, at this point I'm set on the Kukje A2300. Simplicity wins out. As long as I have a turbo I believe I will be fine. If I can get a backhoe with it's own PTO driven power unit, I will go that rout. That kind of has me thinking about putting a diverter on the backhoe's power unit to get some hoses to the loader for a snow blower. Well that's one of many thoughts that include getting a hydraulic thumb going. I'm having trouble finding any info about the Backhoes that TYM is using. It seems they have just revamped their website and now all info for Backhoes and Loaders is nonexistent.

These days it's only the cheap chinese 3pt BHs that have their own pump. Maybe that's a legacy to work with older tractors that didn't have as much hydraulic flow as modern CUTS. No current CUT manufacturer thinks that the system flow is not sufficient to run their BH. Many people with those units run their tractor at a low rpm because at full rpm the BH moves too fast! (do a search on this web site)

Try out the factory BH when you test drive the tractor. I bet it will move more than fast enough for you. And with it you will get the benefit of a subframe mount that does not put all of the BH's substantial forces through the 3pt alone like the 3pt mount does.

I think a subframe BH is a must. Many users here have commented that using a 3pt backhoe may void your warranty. I know there are a few companies like Woods that give you the option for a subframe and pto pump on their BH85 backhoe. They say ask for a quote instead of listing the price. That translates to "this will be really expensive".

It seems the dealer provided TYM branded backhoe will probably be the best option cash wise. Looking through the manufactures sites and then looking at alibaba, it would seem that most of the tractors marketed in the US have Chinese backhoes that are painted and branded to match (with subframe mounts of course).

Branson used Ansung BHs from Korea. That's who made the used one I bought. The current model is made by another Korean company, to the same design. My only complaints with mine are about the Italian made valve stack.

Yes, most CUTs made the past 20 years or so have plenty of hydraulic flow to run a backhoe.
No separate pump needed.
My 2001 tractor (35 HP) has all the hydraulic flow and pressure it needs to run my 8 1/2' backhoe.
Anything over 2100-2200 RPM and the backhoe gets to fast for my liking.

What do you not like about the valve stack?

What do you not like about the valve stack?

Some of the valves are too abrupt. It's nearly impossible to raise or lower the boom without jerking the entire machine around disturbingly hard... that valve does not "feather" easily. I added two one way restrictors to the cylinder (two so I can adjust it in both directions) and that made it about 90% better when adjusted so it still moves fast enough. When I curl the bucket with a load it in, the bucket soimetimes slams into the stop and ejects much of the material. I think part of that is due to how the linkage leverage works- the bucket speeds up as it nears the end of its travel. I can get it to work ok some of the time, that valve is not as bad as the boom one. I have another restrictor to add there to see if that will help. Operating three motions at once helps these problems but does not fix them.

Part of this is my lack of experience as a BH operator. But when I got to try out a Kubota mini ex with electric over hydraulic controls I had no problem operating it smoothly and making it do what I wanted (once we flipped the sae/iso switch to make the controls work how I'm used to). It's not really fair to compare a $60k mini ex to a much cheaper BH attachment, but it indicates that the problems I have with my BH isn't just me.

My Branson's loader valve is similar. I find it nearly impossible to raise/lower and curl at the same time. I had no problem doing that with my old Kubota even though it was my first tractor and the joystick linkage was worn out on that used machine. Feathering the loader is difficult but not impossible. (Branson changed how they run the cables on the new models and that may have made an improvement). It's not a huge issue, I can work around it.

I think a lot of this is the quality of the valves themselves. Kubota's known for making especially good ones. Theoretically I could adapt quality aftermarket valves but that's some work and I don't know whose valves are good and whose are not. The valves I have are made by well known companies.
