Transport lock system

The transport lock system is a simple mechanical system that saves time and ensures safety. Use the rope system to raise the transport lock, engage selective control valve (SCV) 1 to bring the cutterbar into the transport position, and release the rope system to lock for transport.
Shear hub assembly serviceability
Oval-shaped disc removed
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.

Take the shear hub assembly off the cutterbar by removing only eight bolts.
Outer swath wheel
Outer swath wheel
Add the outer swath wheel to the DM50 Series Disc Mower to achieve separation between cut and uncut crop. By keeping the cut crop out of the uncut crop, cutting is not happening twice, which would reduce overall productivity. The swath wheel is fully adjustable up and down the length of the cutterbar, and it bolts directly to the top frame with U-bolts.
Simple float spring tension adjustment
DM50 Series float spring tension adjustment
Set the float spring to get maximum performance during operation. Adjust properly so the down pressure does not damage crop stubble as the skid shoes pass through the field.
Park stand and arm system

The DM50 Series Disc Mower park stand and parking arm work together to transfer the mower’s weight to the cutterbar while in the parked position. This makes the attachment process easier, saving time and frustration.
