Customer Question

I have an old John Deere 300 backhoe, vintage 1974. I'm not a great operator and if I could slow it down a little I'd do less damage. Is there any way to adjust the speed of the hydraulics on that machine?

curtis b :

Welcome to JUST ANSWER heavy equipment. With years of experience, I look forward to doing my best to help.

curtis b :

The hydraulic speed is controlled by the volume of fluid coming to the control valve. This is dependent on the speed of the pump, the only way to slow the flow is to run the engine at a lower rpm.

curtis b :

Have you tried varying the speed of the engine? If you restrict the flow to the control valve, you will increase heat in the oil, due to restriction . Best approach is to use the engine rpm as the speed control, then as you become more proficient, you can speed up the engine to work controls at faster pace.

curtis b :

There is no flow control on the hydraulic system to slow the functions.
