Urethane rolls
The 630 and 635 Side-Pull Mower-Conditioners and the 830 and 835 Center-Pivot Mower-Conditioners are available with a urethane roll conditioner.
The urethane roll conditioner works well in legumes, especially alfalfa, and most all-grass crops.
In general, roll conditioners are better suited for thick-stemmed, cane-type crops, and crops more than 1.5 m (5 ft) tall.
Molded urethane rolls are formed by a cool molding process that does not distort or warp the steel core of the roll:
An intermittent recessed cleat design gives more crimping edges for greater pressure per square inch, which results in superior conditioning and faster crop drying.

Power is distributed by the platform and conditioner drive gearboxes:
-
Gearbox uses heat-treated, steel-forged spur gears for added strength.
-
Drive gears operate in a sealed environment to prevent excessive wear or contamination.
-
Telescoping drivelines ensure positive drive.
-
Spur gears have two to three teeth intermeshing at all times for a smooth, positive drive.
