ClassicTractorProfessor 5,262 #1 Posted May 1, 2016 My 1277 has the 48" mower deck (RL-486) . I'm right in the middle of mowing and threw the deck drive belt...anyone know the size of this belt??? I've searched with no luck I may have found it...Wheel Horse 9783 shows to be 1/2"x71" does that sound right? Share this post Link to post Share on other sites

Do not use it for the mower drive belt. The height of the belt is not high enough and it will flip on its side when passing through the mule drive. Get a ½" Gates black belt. I think it would be an "A69". That would be ½x71. Gates A69 Belt For A-section v-belts, the outside circumference is found by adding 2 inches to the inside length of the belt. So, the outside circumference of the A69 belt is 71 ... Edited May 1, 2016 by N3PUY Share this post Link to post Share on other sites

I'll try that next time...already went to O'Reilly's and picked up a green one...it's the same as what was on it before and I never had any trouble but thanks for the pointer I will keep that in mind Share this post Link to post Share on other sites
