The Triplex Finishing Mower is designed to be transported with ease. A cast clevis hitch is standard and a 2-5/16" ball hitch is optional for road transport. The 5-position hitch adjustment makes it easy to move, regardless of the hitch height of the tow vehicle. The decks are lifted into position by hydraulic cylinders and are automatically locked in place for transport. The decks are unlocked right from the tractor seat using a cable, or can be released using the optional hydraulic system.

Tapered roller bearings in the wheel hubs ensure long- term reliability without needing frequent lubrication. The standard front UHMW roller prevents scalping on uneven turf.

There is a 1-5/8" blade overlap on the 450, while all the other models have a 2-5/8" blade overlap. This overlap helps to prevent stripping, especially when turning.

A forgiving yoke design creates the ability to follow the terrain, yet maintain a seamless finish, available on models 550 and 650.

The model 765 has four wheels on each of the three decks. Models 650 and 550 have four wheels on the wing decks and two on the center deck. The 450 has three wheels on the wing decks and two on the center deck.
