Tips on using a power trowel... same concept as by hand, float, lay down and finish. We use float pans on the machines for the floating operation. You can start floating once the bleed water has evaporated. The sirface looks dull and you only leave about a 1/4 to 1/8 inch deep boot print Float minimim 2 times, 2 directions, overlaping. Next you lay it down with blades at a low angle. And as the concrete hardens increase blade pitch. Same process as by hand. Yes we own a deere 50d excavator, and a deere ct322. Along with small stuff like a power buggie and trowel machines etc.
