To ensure a post pounder works with your 3CX, verify that the attachment's hydraulic flow and pressure requirements match your machine's auxiliary circuit. For your 2017 model, the auxiliary flow rate is about 32 gallons per minute at 3600 PSI. Many top pounders from brands like Eterra or Shaver have models that fit this range. What kind of posts do you plan to drive and what are the ground conditions? Have you checked the GPM requirements for any pounder models you're looking at?

I'm using drill pipe. Ground conditions shouldn't be a issue, kinda rocky but it's sand stone. Thanks for helping with the hydraulic requirements. I am tired of augers and concrete.

Driving drill pipe into rocky sandstone clarifies the application requirements significantly.

Given the material, shift your focus from hydraulic flow to the pounder's impact energy rating, measured in foot-pounds. Consider nitrogen-charged hydraulic hammer designs, since a standard vibratory or drop-weight pounder may lack the force to drive into sandstone efficiently. The 3CX provides enough hydraulic pressure and lift capacity on the backhoe to operate a more powerful commercial-grade unit, so you have good options.

What's the drill pipe's outside diameter? Are you considering a pounder with grapple and tilt?

I have a lot of pipe 2 3/8 and 2 7/8 if I can find one with a grabber and tilt absolutely. Buy once cry once.

Perfect, that confirms the specs. A nitrogen hammer with a grapple and tilt sized for 2 3/8" and 2 7/8" pipe is exactly the right setup for driving into that sandstone.

One last critical thing to consider before you finalize an order is hydraulic heat. A hammer will work your system hard, so you should ask the supplier if they recommend an auxiliary hydraulic cooler for your 3CX to handle continuous runs without overheating.

Have you narrowed it down to a specific brand or model yet?
