What the 630 Mower Conditioner is used for
The 630 is used to cut hay crops and lay them into a controlled swath or windrow. Its conditioner scuffs or crimps stems to help the crop dry more evenly before raking and baling. It is suited to farms that need a pull-type mower conditioner with a roughly 10-foot cut.
Why the John Deere 630 Mower Conditioner stands out
The low-profile modular cutterbar uses six gear-driven discs and has adjustable cutting height. Impeller and roll conditioning choices let the operator match conditioning intensity to crop type. A slip-clutch or overrunning-clutch arrangement helps protect the driveline and cutterbar from shock loads.
Buying a used John Deere 630 Mower Conditioner
Inspect each cutterbar module for leaks, bearing noise, damaged discs, and loose or worn knives. Check the impeller tines or conditioner rolls, belts, gearbox oil, PTO shaft, and clutch operation. Examine the hitch, transport lock, skid shoes, and hydraulic hoses for wear or damage.
