Kubota DM vs DMC: What Is the Difference Between a Disc Mower and a Disc Mower Conditioner?
Wondering whether you need a Kubota DM disc mower or DMC disc mower conditioner? Learn the difference, how tine conditioning helps hay dry faster, and which mower fits your hay operation.
When hay season is moving fast and weather windows are tight, the mower you use can make a major difference. Kubota’s DM Series and DMC Series both cut hay, but they are built for different jobs. The DM Series is designed as a disc mower, while the DMC Series is a disc mower conditioner — meaning it cuts the crop and conditions it to help it dry more efficiently.
What Is the Kubota DM Series?
The Kubota DM Series is mainly about cutting.
A DM disc mower uses rotating discs and knives to cut the crop cleanly and lay it down behind the mower. On the DM5000 Series, Kubota highlights features such as three-bladed discs, a fully welded cutterbar, counter-rotating discs, active suspension, and quick-change knives.
What Is the Kubota DMC Series?
The Kubota DMC Series does more than cut.
A DMC is a disc mower conditioner, which means it cuts the hay and then runs the crop through a conditioning system before laying it down. Depending on the model, Kubota DMC machines may use a SemiSwing tine conditioner or rubber roller conditioner.
The Important Part: How the DMC Tines Help Hay Dry
On a Kubota DMC model equipped with a tine conditioner, the tines pick up the freshly cut crop after the cutterbar and move it through the conditioner. As the crop passes through, the tines work it against the adjustable hood, scuffing and abrading the stems and outer plant surface. That conditioning effect helps open the crop so moisture can escape more quickly, improving dry-down compared to simply cutting and laying the crop on the ground.
For grass hay, a tine conditioner can be a strong option because it helps scuff the crop and improve dry-down. For more delicate crops like alfalfa or clover, roller conditioning may be a better fit because preserving leaves is important for feed quality.
