My F series Toolcat has about 250 hours +/-. About three months ago I noticed that the RPMs dance all over the place at low to mid rpms when the machine is in gear and moving forward. It's not at every throttle position but rather a few but those happen to be where I like to set the throttle for running around or light grapple work.
At idle or when I'm running my chipper, it idles just fine at low, mid, and high rpms.
When I press the accelerator, at those lower rpms, it almost sounds like the engine is surging. It doesn't seem to have power loss but you can hear and see the rpms dancing as much as 50 rpms. I know my Bobcat will go up and down in rpms but you can't really hear anything or feel anything different..just runs like a normal machine would. I've had several people tell me the Toolcat doesn't sound right or that it sounds like it is revving up and down (but not above where the throttle is set).
I had my Bobcat dealer send out a very experienced tech and he said nothing was wrong yet it still does it. The next step is taking it into the shop but I'd rather not if I don't have to.
My B series didn't do that. Where you set the throttle, the rpms stayed and only moved up and down under load but it was consistent.
Does anyone have any ideas or what other info should I post about it?
