gwest_ca-(File Mod) 11,033 #2 Posted December 25, 2020 Welcome to the forum. Look under the left side of the seat or front of the seat for a decal with the tractor model number and serial number. If it is gone post all the numbers off the engine decal including the serial number. With those we should be able to link you to tractor manuals. The mower deck you have is a 37" width of cut side discharge. There are two versions of that deck. One uses a regular 4-sided belt so that deck has flat idlers. The other uses a 6-sided belt (Like two 4-sided belts back to back) with all V-pulleys. So the front idler assemblies are different in the pullies only. Two v-idlers or one flat idler and one V-idler. Let us know what you find. Garry Share this post Link to post Share on other sites

953 nut 55,099 #4 Posted December 26, 2020 The component that ties the engine PTO to the deck via a V Belt is called a Mule Drive. If you don't have one some of our members like @daveoman1966, @A-Z Tractor or @Ed Kennell can probably fix you up. Here is an exploded view of what it looks like. 1 1 Share this post Link to post Share on other sites
