New in 2020! Allen Engineering is excited to announce our RP235 and RP245 polishing riders! These machines were designed with the high volume concrete polisher in mind. These riding trowels come as designed to achieve high rotor speeds to achieve high torque while polishing, and they also come equipped with special dolly jacks that ensure transportation indoors can be done with ease, as well as allowing for quick change of polishing pads. These designs are also built on our popular edging riding trowel frame to allow contractors to get extremely close to the wall while polishing.
