Product Overview

This mower is designed to work with 42-52 horsepower tractors and has dual spindles with two free-swinging blades that reduce the shock of impact when a stationary object is contracted. CHAINS NOT INCLUDED. Can be ordered direct ship from the vendor through us. The PTO Shaft that is included is a length to fit a wide variety of tractors, and possible that it is too long for your application.  If the PTO Shaft needs to be shortened, follow the manufacturer's instructions in the manual and/or contact us if you have questions.  If the shaft is too long, it could damage both the mower's gearbox and gearbox mounting plate on the deck.
