The Chelsea 489 P.T.O. is another example of why Chelsea P.T.O. technology is the best in the business. It’s specifically designed to reduce mounting time. The one-piece, cast iron P.T.O. housing bolts on to the 8-Bolt transmission opening, but gives the same torque capacity as the 442 Series. That means one less part to buy, one less surface to leak, and faster installation. The 489 has strong tapered bearings instead of needle bearings for greater load bearing capability. Thirty six output options including Chelsea’s popular 360° rotatable flange. Eleven internal speed ratios and ten shift options plus a self-lube option for transmissions that have problems getting lubrication to the P.T.O. make this one versatile P.T.O. Take advantage of over 65 years of Chelsea P.T.O. technology to increase performance and lower costs.
