CK30 RPM Normal Drop Under Road Load

[Mousefield]

Correct. They are gutless in high gear and it is only a road transport gear more than anything. Mine loses a lot of rpm on a hill or even a slight rise. If it struggles too much just ease your foot off the fwd pedal a bit and allow it to come back to the next ratio until you are past the rise. Personally, I never use mine above 2000 rpm and usually about 1800 and it works fine.

As mentioned in my earlier post I find if trying to travel in high gear on anything other than a paved road the tractor bounces way to much. So I am almost always in middle gear.

Spank, that drop sounds normal to me & is about what mine does. Remember to ease up on the pedal when you start to climb a hill. Big hills will require a range shift to MED.
Alien I never go down the road without first putting the throttle on the red triangle....about 2600 rpm. Also, I always work my DK40 in the 2300-2400 range when using any pto powered implement or when dragging the box. I find that the tractor just likes that higher rpm range to do that kind of work and anything lower just feels sluggish to me.

If you run the engine speed up a little higher you will find that the HST performance improves.

...............When running full forward speed (HST foot pedal down all the way) on level road the Engine would drop 100 to 2400. Some of the short up grades the RPM would drop a total of 200 to 2300 Engine RPM. Does this seem normal? I was thinking the engine governer might maintain the engine RPM closer to unloaded set engine speed.

When do you get to the point that you should select the next lower HST Range for road transport?.....................................

The throttle lever position determines the amount of injector pump stroke that is used in delivery of fuel to the injectors. The governor's primary function in life is to reduce that stroke as the engine starts to overspeed. As you add more load to the engine, it will need to burn more fuel in order to maintain rpms.

If it sounds like it is starting to labor just bump up the throttle. If you stop the tractor without throttling down, that's when the governor will kick in to reduce fuel delivery as the load drops off.

If you start to reach the point where there is no more throttle to add to keep you at 2500, then you are at the point where you need to reduce the load.

As long as your staying in the low 2's, as you have descibed, I wouldn't be concerned. But don't be afraid to add a little more fuel into the mix to keep it running up where you want it either. The loads are dynamic and it is normal for the operator to adjust to them.

Everyone Thanks for a great Discussion and help in answering my questions.

Sounds like I am not abusing the tractor as not lugging the engine. Do not expect to use it for road transport much but in this case had to move some cut wood a short distance. I will admit rolling the cut log 18 inch long sections into the FEL Bucket on the ground was much easier that lifting them into the pick-up bed. Some of the wood sections just barely fit into the bucket. Next time I lift them they will have been split into smaller pieces for firewood.

One good thing I was able to confirm is when going downhill on dry pavement just easing off on the HST pedal would slow the movement down and allow you to stop the tractor from full speed without using the brakes. Nice to know when the grades get steeper if you have good traction going down hill you can slow and stop well with the HST.

Thanks again for the help

One more tip...if it's steep and wet(pavement) or steep on dirt/gravel, and you had a heavy load(dirt/logs/rocks) ALWAYS have it in 4wd. You will then have engine braking on all 4 wheels instead of just the rear and much more anti sliding control.

~don't ask me how I know this~

Thanks for the Tip. (I am sure you saw someone else and learned from them) I am now mature enough (sometimes) that I can learn from others.

I do remember as a kid watching those that had to hold the spark plug wire lead on the single cylinder engine while the older kid pulled the starter. I learned from watching even then. I am still wondering what happens when you pee on the electric fence.

Thanks again I am still learning.

do not worry about peeing on an electric fence, pee does not conduct electricity go ahead TRY IT
