Cutterbar serviceability is easier on the DM50 Series Disc Mowers. Remove the oval-shaped disc(s) with only four bolts per disc. The shear hub assembly can be serviced by removing the remaining four bolts. This will save time and oil replacement costs by not splitting the entire cutterbar to replace the sheared hubs as required in previous models.
