46 Inch Craftsman 917273021 Garden Tractor Belt Install and Connecting Deck

This video will overview how to replace the two deck belts (144959, and 139573) on a 46 Inch Craftsman 917273021 Garden Tractor, and how to connect the mowing deck. On this tractor, the two deck belts remain in tension all the time, so the procedure critically requires one to avoid getting their hands or fingers stuck in the belts/pulleys.

Nice clearly spoken tutorial. Often, I slow down a video to process what the creator's saying. I wanted to slow this down for the visual parts, then I decided not to because there was little to see, as far as watching your steps and your speech pace was wasy, (edit: oops, I meant "easy") to comprehend. BTW, You may want to upgrade your primary belt... I have a '94 GT6000 & 2000 GT3000, both equiped w/ a 50" mowing deck & similar Kohler V-Twin engines. I use the newer upgraded primary belt on both. Craftsman replaced that older belt #139573 with part #148763, it's thicker @ 5/8" & to compensate for it being a bit wider, it's approx. 3" longer @ 86". Thanks for the video.

Thank you for your helpful feedback! I have performed the primary belt upgrade to 148763. However, the belt got ripped up on the deck while in use following the upgrade. Have you had this experience or did it work?

GOOD PRESENTATION

[@PotomacRepair]

Thank you!

Great video. This helped me a lot. But My drive belt 139573 is too loose. Is there an adjustment to tighten a pull for that belt that goes to the engine drive pully? The mower blades take a while to fully turn to the fast speed I need to cut. then slows in taller grass. Pease Help! lol thank you.

[@PotomacRepair]

Thank you for your valuable feedback! What model tractor do you have? The Craftsman 917273021 Garden Tractor does not have a mechanism to tighten Belt 139573. You have to replace with a new belt. If Belt 139573 has gotten too loose, you probably ought to replace the deck belt too. Good luck!
