Upper Canada 213 #1 Posted June 4, 2018 I am trying to figure out the pto belt size required for a 36" rear discharge mower deck on a C120. The deck is a 36" rear discharge deck off my Commando 800. The commando 800 is out of commission so I put the deck on the C120 for the time being but the Commando 800 belt is too short and the belt from the C120 42" side discharge deck is way too long. Thanks. Share this post Link to post Share on other sites

Upper Canada 213 #3 Posted June 4, 2018 Well the model tag is missing from the deck. I believe it would be the older deck as it is original to the 1973 Commando 800 it was on. I think it's a 1973 Commandi 800 from when I looked it up. Share this post Link to post Share on other sites
Upper Canada 213 #4 Posted June 4, 2018 Just found this in manual section. So it looks like the 97" belt. Thanks daveoman1966 for the guidance. Your answer helped me a lot. I love this forum!
