Dunedainranger 4 #1 Posted July 29, 2023 Hello, I picked up a C120 Automatic, believe it to be '76 model. Came with a mower deck, IH 42" plow blade, and a WH snow blower. I am having a hard time identifying my mower deck, I am assuming a 42". These are the measurements I took: Blade tip to tip - 40.75" Discharge tip, to opposite wall - 41.25" Blade length - 13.75 - 13.875" Width of deck - 21.125 Length of deck - 47.125 Finally, I really had a hard time getting the deck attached. It seems to have bent brackets and a round bar that wants to dislodge as soon as it gets fully mounted. The front lifting bracket was not easy to get locked into place. The non-discharge side height adjustment wheel had to be removed to give clearance when mounting. I also found signs of patch work, new hardware, etc. I would like as much info as possible so I can start rwbuilding this thing - the JD is down and I really need to mow the grass. I know the WH is solid machine, just need mower drive belt, spindle belt is OK, and help with repair suggestions based off the above observations. Thank you, everyone. 2 Share this post Link to post Share on other sites
Sparky-(Admin) 21,405 #2 Posted July 30, 2023 I see you’re missing the adjustment rod that goes here (circled in the picture). Also that deck looks older than the tractor, I’m wondering if it’s been modified to work with your year tractor. 2 Share this post Link to post Share on other sites

Just hard to see it. Any guess why the one wheel interferes with the rear tire? I have more pictures showing some modifocations to the deck that I could find.

peter lena 8,722 #7 Posted July 30, 2023 @Dunedainranger in addidition to many other areas that need help , after you pull of the blades for replacement , would ,get some KRIOL , OR DEEP CREEP penetrating oil totaly on / into that crusty bottom side , would also prop it up to the sun , usubg the lift frame against something solid , have any 2 x 8 wood ? prop it up to angle the sun , so the deck gets hot and sucks in the grunge killing lubricant . you will have a lot of options , if you are going to rebuild the spindles , new bearings , with a clean out and re grease , hi temp 550 deg lucas grease , related idler pulleys , also muel drive .pto drive , basically the more issues you eliminate while you are their , the easier / quieter that deck will run . also realise as a newbie , that might seam overwhelming . overall conditition of that deck , reflects , painting , and little else . lots of related rebuilding info on this site , take advantage of it , good luck , pete Share this post Link to post Share on other sites

Belts usually did not change - all 42" side discharge decks use the same belts. 2 Share this post Link to post Share on other sites

gwest_ca-(File Mod) 11,096 #10 Posted July 30, 2023 I see Drive belt 102742 (1/2" x 103") Spindle belt 6738 (1/2" x 86") Many illustrated parts lists are shared with a similar but larger deck but often fail to identify what deck (42" and 48") uses what belts. That is why the belts have ben added to the deck information page. Click on the fuzzy picture in the link to see them 1 1 Share this post Link to post Share on other sites
