Like its counterpart, the John Deere X749 relies on a 4-wheel drive that works in forward and reverse, as separate front-wheel motors adjust peed in turns to eliminate turf scuffing. It is essence the top model of the series, although certain specs remain the same, including a 24-hp, liquid-cooled, 3-cylinder, Yanmar diesel engine for power, and a heavy-duty welded frame that can support up to 168 lb. of added weight (attachments).
