Contact me for additional information. The 48C Convertible Mower uses the latest in 3-spindle mowing technology to raise performance to a new level. The 3 mm deck stamping is all new. It has been designed to handle more material. The design will also result in improved cut quality and more uniform discharge in difficult mowing conditions. Mower blade overlap is 40 mm compared to 25 mm for the earlier 48-in. This increased blade overlap reduces the chance of striping between blades. Contact me for additional information at.
