Coordinated valving?

[chelydra]

Most of my non-car vehicular experience before buying a CK20HST was with Bobcats and helicopters. (They drive similarly, though the Bobcat's a lot more stable, and you can let go and relax at most points.) I'm used to coordinating multiple control inputs - say, raise and roll the loader bucket at the same time.

It may just be my technique, or the fact that I run at low RPMs (typically about about 2200-2400 RPM for loading, 1800-2000 for BH work) - with the loader, it's to keep noise down; with the BH, to let me edge the stick carefully around plants and buildings. But especially with the BH, it seems to "like" to do just one thing at a time. It would be nice to swing, lower and roll the BH at the same time.

Could my valving be incorrect, my handling inept, pump speed too low, or is it supposed to work like that?

Thanks-

If you run at faster rpm's you should be able to "multitask" the backhoe movements. I have a different backhoe (Rhino 75), it's slow when mulitasking at low rpms, and is nice and smooth at high rpms. But, at high rpms you have to watch that swing speed if only swinging. That baby flies! Make 2 or more movements simultaneously and it is very smooth and controllable.

Try higher rpms. Takes a little practice, but gives way faster operations. But, at 2000 rpms, it should be pretty good anyway. That's where I run when I want to work "fast". Slow and more delicate: 1200 rpms.

Practice, practice, practice, CHEL.

I do it like GITTYUP, and I am more often than not using 2 controls at once.

I took a helicopter piloting lesson once (Robinson R22) and I am sure that
even that multi-use control technique can become second nature. To me,
it felt like the first time I ever ran an excavator. Not pretty at all!

(A Bobcat is stable? Really?)
