Ed Kennell 42,042 #2 Posted November 8, 2013 No belts don't normally break if it is the correct belt and if it is installed properly. Can you give more details. What is the belt driving ? Share this post Link to post Share on other sites

squonk 43,843 #5 Posted November 8, 2013 What kind of shape are are the mule drive bearings in? Share this post Link to post Share on other sites
Ed Kennell 42,042 #6 Posted November 8, 2013 Its the powertake off belt to the mower deck,it engages the blades Do the blades spin free when the mule drive is loosened? Does the belt rub the deck pulley guard or any thing else with the deck raised and lowered? Is the belt on the mule drive correctly? Share this post Link to post Share on other sites
953 nut 60,074 #7 Posted November 9, 2013 As has been stated, mule drive or deck bearings or the guard on the muel drive rubbing would be places to look. Also, are you using a fractional horse power belt such as an A-100. A previous owner may have used an automotive fan belt that fit, but they are no good for this application. Good luck and keep us posted. Share this post Link to post Share on other sites
Ed Kennell 42,042 #8 Posted November 9, 2013 Dean,check all the pulleys for broken pieces and obstructions at the bottom of the VEE. I have found clumps of dried grass and grease down in the deck drive pulley that causes I/rev tensioning and release of the belt. Share this post Link to post Share on other sites
