Kelly 1,033 #1 Posted April 2, 2012 I have a beater lawn tractor here that my son loves to use it's a vert shaft B-112 with a briggs in it, runs pretty good, has a monster 42" RD deck on it, same deck with different hangers on it as GT, but anyway the drive belt broke, I don't want to put a $35 factory belt on it, the tractor was only $25 so I crossed the factory 106518 numbers to a Gates 6887 / 4L870K I want to try to get a cheap belt from TSC I just want to be sure I'm reading the number right, 4L= 1/2" wide, 870 =87" long, K = Kevlar wraped, am I right?

brybrychrismer 17 #2 Posted April 2, 2012 I pretty sure thats correct i had to do a replacement on one of mine and it was a 4L for my C120. The Belts from tractor supply work pretty well. B.A. Share this post Link to post Share on other sites
jdog_kustoms 82 #3 Posted April 2, 2012 just remember some belts are measured on the inside and some on the outside for some dumb reason Share this post Link to post Share on other sites
BOWTIE 226 #4 Posted April 2, 2012 KELLY, 87" X 1/2" IS MEASURE ON THE OUTSIDE. AUTOMOTIVE BELTS ARE MEASURE ON THE INSIDE AND FRACTIONAL HORSEPOWER (LAWN MOWER) BELTS ARE MEASURE ON THE OUTSIDE. JUST MY TWO CENTS WORTH.. BOWTIE IN OHIO Share this post Link to post Share on other sites
