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.

The maximum engine RPM is about 2900 on my DK40SE. 1900 - 2000 range is just for the backhoe use. I was told by the dealer that Kioti recommends 2600 rpm for best HST performance. Damage the engine statement is not logical since this is the same motor Kioti uses for the standard shift transmission tractors. The red triangle is engine rpms needed for the PTO.

Hi All,
The newer 24 series backhoes are very responsive to volume. All our tractors are set to run at a certain pressure(normally around 2500psi +/- 100) The backhoe should be lower, set at around 2100psi. this eliminates breaking stuff. When you raise the RPMs you gain volume and this will speed up the response time. If you are learning, run lower rpms until you get a good feel for the machine. I would guess that you can get full power and plenty of speed in the 1600 to 2000 range and possibly use less fuel that if you run at PTO speeds of 2700 engine rpms. This will in no way hurt your tractor. The problem comes when you run a rotary cutter or tiller at too low rpms and you start to bog down the engine and this may cause problems with the tractor.
Run the backhoe at whatever rpm gives you a comfortable speed.
Good Luck,

Thanks for the details Dave.

I have a 2485 and found the sweet spot to be around 1850 rpms +/- a few rpms.
I found at 2000 or slightly over the BH is few jerky and unstable in movements.
