Just finished installing Agrital all glass cab on MX 5100. Fit and finish to tractor is not perfect but I am very pleased. $4610 complete, heat (ceiling unit), 2 mirrors, rear wiper, locking doors. Operating rear window and windshield. Even a coat and hat hook and front lights (roof). More options are avail. A/C was a bridge too far but avail if desired. Look at Agrital website for photos. They are representative of my installation. Again, not perfect, but I'm pleased as heck.
