I usually have it at idle or a little above. I can't find anything in the manual. Any benefit to higher rpm other than moving a little quicker?
While I agree for the most part, digging at 2000 rather than idle has allowed me to lift and move larger tree stumps.Engine speed doesn’t affect the hydraulic pressure. The backhoe will have the same digging force at idle as it does with the throttle wide open. What changes with engine rpm is the gallons per minute the pump produces. The faster the engine rpm, the quicker the pump operates and quicker the cylinders will fill, resulting in more “responsive” hydraulics. Slow the engine down and the hydraulics will operate more slowly. But even at idle the backhoe will dig just as well, albiet at a more leisurely pace.
I’ll typically start at idle until I’m used to the controls, then speed it up a bit. There is a certain point for each operator where the controls will feel too fast or touchy and for each operator it will be different. Start slow and ramp up the speed as you are comfortable. If the backhoe feels touchy or the movements are too quick, slow the rpms down.
It’s really just a balancing act. Slow rpm means more precision but at a slower digging speed. High rpm means a faster digging speed but with less precise movements.
The only limitation on rpm that I recall is to keep it under 2400 on a hot day so the hydraulic system doesn’t build too much heat.
That the way I do it as well:cheers: The fumes and heat sort of temper my RPM's
