40 acres of Stump Removals

[SkidrowJoe]

We are a tree service, so our stump removals are limited in comparison.  We were looking into renting a hydra stumper 250-300 hp grinder to complete the task.  Just curious what the output would be acres/day, with relatively flat ground with minimal rocks, and average stump diameters 20" of various hardwoods.

Or we are open to other options?

Thank you in advance!

I've sent a PM.  I think you'd find that terribly slow and there are better options.  Can I ask what the end purpose of the site would be?  Do they want the organic material removed or retained on site?  ie is this going to be a fracking pad.warehouse site/etc or a forest/ag use?

Depends on the skill of the operator. One operator might do twice the area and take half the task time as a low skill operator with the same machine.

D8 class dozer ( or bigger) with a blade plough or cutterbar. Much depends on soil type and stump size from there but it'll work out cheapest in dollars / acre every time for natural stumps.

Row crop type stumps that Savannah plough above might beat it... maybe. Depends on soil type and stump size.
