New 2023 New Holland DuraDisc 109M Mounted Disc Mower (9′)

HAY: IT’S IN OUR DNA.
New Holland heavy-duty disc mowers breeze through the toughest conditions to give you a clean, even cut in less time. Discs spin up to 3,000 rpm, producing a knife tip speed of up to 187 mph to slice through dense, wet grasses, fire ant hills and gopher mounds. Select from four new heavy-duty models, including a new pull-type model with a cut width of over 10 feet.
A CUT ABOVE THE REST
All four heavy-duty disc mower models feature the latest advance in New Holland true modular cutterbar technologyÑthe MowMax cutterbar equipped with the ShockPROª cutterbar protection system. This is the same design used on larger Discbine¨ disc mower-conditioners so you are assured of maximum durability and peace of mind. Each disc module is an individually sealed gear case with a dedicated oil reservoir. Even when cutting on slopes, thereÕs never an oil starvation issue. The gears stay fully lubricated and work reliably. If an internal component ever fails, thereÕs no chance that a broken piece can circulate in the oil bath and damage other modules. And, each gear case is connected with independent, hard- ened alloy drive shafts, not a single-piece drive shaft that can twist or shear. When routine maintenance is required, itÕs fast and inexpensive.
ADDITIONAL MOWMAXª FEATURES
Lower-profile rock guards allow for closer cutting at a flatter cutting angle
Stepped module spacers improve the straight- ness of the cutterbar, allowing it to run more lightly and smoothly for consistent cut height and less wear.
The fit of the top cap bearing to the housing is optimized to extend bearing life.
More gentle bends in the knife bolt area of the ÒturtleÓ reduce wear concentration.
Hardened alloy module drive shafts with dampeners eliminate vibration wear.
Stronger top cap gear and the ShockPRO hub design eliminates the need to change top cap gear assemblies if there is impact from a foreign object. A partial complement of splines allows the hub to fail instead of the gears
The ShockPROª Advantage
Replaceable ShockPRO hubs protect the entire cutterbar driveline to minimize downtime and repair costs if the machine encounters a field obstruction. Economical ShockPRO hubs absorb the shock of the impact before damage can occur to expensive drive components. If necessary, these hubs can be replaced in the field in under ten minutes, at minimal cost.
