springerspaniel109 3 #1 Posted July 23, 2023 Hello. I am in desperate need of help. Today while I was mowing my lawn with my Wheelhorse c161, a belt fell off. I am 80% sure that it is the drive belt. I am not good with mechanics and made this account just to ask for help as to how I go about putting it back on. After doing some research, I know that there is a flat part and a more triangle shaped part of a belt and those go into certain pulleys. I am also aware that the belt goes down to one of the pulleys on the mower deck. I am having the most difficult time with the smaller pulley on the front. I am struggling to find a helpful video. If someone could please explain to me how this goes back on in very basic terms it would be incredibly helpful. I have uploaded some pictures of what I have.

Lee1977 6,771 #2 Posted July 23, 2023 (edited) Don't see anything wrong with the belt. Belt no. WH 102742 . Tractor supply blue belt 1/2" x 103". The belt comes off the larger pulley to the v-grove pulley on the mule drive back to the deck drive pulley and and back to the mule drive flat pulley with the flat side of the belt. Then tighten the mule drive by turning it to the left. You may need to turn it to the right to loosen and get the belt back in place.

ineedanother 1,369 #3 Posted July 23, 2023 hey @springerspaniel109 I've posted a picture of a mule drive in case you're not familiar with that term. From what I can see from yours, you might not have the adjusting knob on the front which might have led to your issue as the belt was too loose and wasn't adjusted. You'll need to be able to turn that screw shaft that the knob is supposed to be on. Clockwise would tighten the belt, and counter-clockwise will loosen it (or to provide slack in order to install a belt). Loosen the tension on the mule drive (counter-clockwise) and reinstall your belt on the large groove (closest to the motor) on the PTO and then route the belt, Vs in Vs, and flat side of the belt on flat pulleys. Once it's on, tighten the mule drive adjustment WITH THE TRACTOR NOT RUNNING. If your safety switches are still in place, someone will have to be on the seat with the PTO engaged, so you might need an assistant to adjust the tension on the belt with the mule drive to a point where the belt doesn't slip when you engage grass, but not overly tight. 2 Share this post Link to post Share on other sites

Ed Kennell 38,588 #6 Posted July 23, 2023 Oh, to the Springer. BTW, I had the pleasure of owning Springers back in the day. Amazing bird dogs on ringnecks. Barney 1965-1978 2 Share this post Link to post Share on other sites
squonk 41,290 #7 Posted July 23, 2023 Also without the belt guard on the mule drive, you might get a stick or something in the belt that could throw it off. 2 Share this post Link to post Share on other sites
springerspaniel109 3 #8 Posted July 23, 2023 Thank you all so much for your help. After a few tries, I got the belt back on! I appreciate all of your input and thoughts, they were very helpful. @Ed Kennell this is my springer Milo! He's three years old. 3 Share this post Link to post Share on other sites
