Has anyone ever used a H.F. LARGE jackhammer AND a Bosch Brute jackhammer?

I need to break up some limestone and harder rocks underground.

I already bought a H.F. unit but haven't gotten it yet.

Has anyone every made one self-supporting on a 3 or four-wheeled cart
whereby one didn't have to hold the unit?

Thanks

In the past I have just rented a Bosch. It worked well for the concrete but
a word of caution, the rental yard charged me to re-sharpen each bit when I
really didn't need more than one of them for the task. They claimed that
they had to be re-heat treated every time they were dressed hence the
charge.

I think you would have to have an awful lot of demo work to justify
purchasing one of these tools.

they come up with this striped stuff.
