videorov 0 #1 Posted August 5, 2019 (edited) Has anyone installed a xtremeFatboy on a Toro Groundmaster 120 Do you know anyone that has installed the Xtreme Outdoor Power Equipment X0491 Replaces Toro 54-0220 PTO Clutch Heavy Duty Fatboy & HighTorque Upgrade On a Toro Groundmaster 120 and if they had any problems getting installed with the space you have to work with on that mower? I wonder if this model has a notch for it to slide over the square Key? I have used the OGURA MA-GT-TROC brand in the past and thought I would try the xtreme brand if it will fit? Has anyone done this? Hope someone can help. Edited August 5, 2019 by videorov Share this post Link to post Share on other sites
