Backhoe advice - thanks

[BubbaBillyBob]

All--

Quite some time ago, I was reading everything I could about backhoe operation. I have a Mahindra 5545, 4WD and a frame mounted backhoe, plus some other stuff.
.
An experienced backhoe operator wrote that it was not necessary to run the engine at brush hog speed; 2100rpm for me. I knew that was wrong, of course.

But I tried it anyway. Ha! The guy that was wrong was me! Now, I set the throttle to whatever rpm I think the job requires, which is almost always well below 2100rpm.

I do not know who that guy is, but it is long past time that I thank him. THANK YOU.

Yep! Folks on here are very knowledgeable on a lot of things, not just tractor stuff. I find it amazing the wealth of knowledge here and the willingness to share it.

Also, when you run hydraulics, not just backhoe, the engine speed determines how much flow you have. If you're trying to be accurate and move the implement slowly, you'll want a low engine speed. You'll have a slower movement rate than if the engine is at full rpm. Also, keep in mind that turbo charged engines have a "fast idle" speed to avoid "wet stack". Mine is 1200 rpm. I run my engine a little above that for hydraulic implements.

agree with slower rpms unless............................................... DPF wants higher exhaust temps than say 1500 rpm generates. So depends on what your machine is designed for.

For sure slow flow rates can be big beneifit especially for inexperianced operators or machines whose quality of valves maybe not the highest. Can help operator be smoother. On larger / newer / commercial machines though we don't throttle back excavators or backhoes.

somewhat matter of preference but also depends on what machine.

Cheers and Merry Christmas all

Sure helps to slow down as you are learning the machine, or working close to something you don't want backhoed.

I agree with this, after running backhoes for the last 25 years. Lots of variables.

True, If working near a building running my 550 Ford TLB at higher revs, it would be like asking to bang the boom into a building with the "touchy" swing control it has

I've never ran a backhoe that required high engine speed. Half throttle is usually more than enough.
