One of those Clarke buffers from HD with that Hexpin system. I tried a couple different types of heads. Would have been easier to use a nail file to get the sealer off the concrete. They gave me my money back. Tomorrow I'll rent the Edco diamond grinder, you get what you pay for...

Do the rental companies offer you different grit levels?
I just rented one last weekend... the exact same one from HD. it worked for me but because the hex pin is so tall, it lifts the machine a few inches off the ground. So if you start the machine on a very rough surface, it will want to grab and kick away from you. Squeezing the handles is what makes the machine run, so as you hold on to the handles tighter to keep it from kicking away you are making the situation worse.
I got a couple big gouges in my floor before I learned to just let go.
I was about to take mine back and ask for my $$ but then I figured the key is to start in a smooth area and once the machine is up to speed, slowly move into the rougher areas of the concrete.
I did 1200 sq ft and about 1/3 to 1/2 way through it really seemed to decrease in cutting ability. The heads had noticeable wear by the time I was done.

That combo is only good for light jobs. There's just not the weight or media to cut into existing coatings or get a good bite on the concrete.
Controlling low speed (170-ish rpm) buffers can be a bit tricky at first. Here's a couple of tips... If the handle is adjustable set it so that it hits you right at the belt line, that way you can use your hips and body mass to help move it around instead of just your arms. Many are either on or off, no variable speed, so as 6th Gear mentioned start on a smooth area and them move to rougher spots. Here's the big tip - if you shift the balance of the machine towards the front the machine will want to head to the right, if you tip it so it's riding more on the back of the disc, it will want to track to the left (or visa verse - can't ever remember) once you get that under control, it's an easy step to find that neutral balance between front and back that will allow the machine to float and move just by gentle nudges.
