G'day everyone, A customer of mine has a 2006 White ride-on 13AP606H790 46" cut. It keeps chewing out the PTO belt (754-04064), I know its an alignment issue between the top pulley, idler pulley on belt engaging mechanism and top pulley on left hand spindle assembly on the deck. Has anyone else had this problem and if so how did you fix the problem, any advice or help would be very much appreciated cheers Mike

Those old mtd's were prone to deck belt problems. Check the angle of the deck compared to the ground, should be up slightly at the back, but only 10mm or so. Then start looking at the idler pulley, you may need to bend the bracket to get the best of what you can, keep in mind it needs to work up high as well as down low on the cutter height.

Another option on from naths point is to see what height setting the customer wants to use and then try and align the deck to the belt as best you can at that setting height

Also check for sloppiest of the pivot points of the idler swing assembly plus that they have the right idler pulleys on it. Another thought make the belt retainer pins are in the right place in reference to the belt when the belt is engaged. I have seen the belt on the wrong side of the pins on customer installed belts.

I don't see many of this design in the shop so my experience is limited.

Thanks to everyone with their input in fixing this 2006 White ride-on, I looked at everything that was suggested. I tweaked this and that and put a longer bolt in top pulley which lowered the pulley by 10mm adjusted the engaging idler pulley bracket. It seems to work ok now. customer is happy cheers Mike
