kioti back hoe

[bullet20]

what rpm's are reccomended to run the kb2475???

 

[JoelD]

I run different rpm depending on what I'm doing

For digging i typically run around 1500-2000

I run my tractor at 2000 rpms when using the backhoe. Anything higher and the swing is too fast. Higher rpm's does not mean more power at the backhoe, you will still hit the relief valves, just quicker.

I have a Woods backhoe on my CK35, normally run it at 1,700 - 1,800 RPM.

I'm in the same ball park. Usually 1800 to 2000 rpm's. Like Dmace said, too many RPM's and it's just jerky. I like smooth and steady. These BH's are awesome to work with, you will love it!

Brings up a good point, in theory if all of your valves and pump are working perfectly and there is no blow by or leaking of any kind, the hoe will have identical power at any pump speed.

As I've noticed, this is typically not the case and I get a little more power with more rpm.

The point above is a valid one and most people think more hydraulic power comes with more rpm. Assuming that you'll hit bypass easily within the power of the motor, you'd have no additional power with rpm.

i put 140' of water line in today on the side of a goat cliff , finding 1500-2000 pretty nice. might i add being drawn up at times lol steep crap

Agree. 1900 - 2000 rpms seems to be the best.

Then what is the redline on the tach(about 2300) for.? Kioti DK55
Someone told me that if you don't have the rpm's up enough,that I could damage the tractor? Is this true for backhoe? Or only pto- mower?

A picture of your tach would help but most likely you are talking about the PTO mark which is where your engine rpms need to be in order to have 540 rpms at the rear PTO. If you have an HST, then you want to keep the rpms at a minimum of 2,000 but only when you are actually moving. If your stopped and just using the backhoe then you can go lower. Assuming your DK55 is relatively new, they have a rated engine speed of 2600 rpms, that is the max you want to run.

Sometimes I run the backhoe at just 1500 when I am working in a tight area and want the slow smooth movement. It still has just as much digging power.
