OK, I know that most of the rigs here on the forum are GT, not LT and they are mostly older rebuilds. However, I could use some help with my anytime use 2007 JD X320. It has a 48" mower deck and that is where my problem is occurring. I had an idler pulley lock up and it smoked the belt. Got a new pulley and a new belt and it keeps jumping track. Pulled the whole deck off and checked all of the blade hubs and idlers with the belt off and they feel good. When the PTO switch is turned on, it instantly jumps an idler pulley. The belt is a brand new Gates and feels plenty tight when pulling on the tension idler when installing. Could the PTO cause some type of jump or slippage to make it jump track? The pulley that it keeps jumping track on, I even moved the belt guide in as close as I could and it still managed to squeeze through it. Any help/ideas would be greatly appreciated.

Are all of your deck pulleys aligned with each other?

Do you have the JD part # for the belt? JD uses belts and pulleys with a custom angle to them, which is why off the shelf belts usually do not work well or last very long.

Have one that did the same thing. Finally carried it to the dealership after 2 belts and they put a new belt on and leveled the deck to J.D. specs and it has never did it again. The deck has to be leveled to their specs with a gauge. The gauge is available for purchase.

I can answer some of these but not all. The pulleys should be lined up. The one is brand new and all of the others felt good in the mounting realm. no jiggle in the bearings with smooth rotation.

I'm afraid cootertom that this will be the case. The Gates belt really..............fits the grooves tight and snug and as I type here, the action it is displaying is similar to the belt getting stuck and then popping and it is jolting to the point of jumping pulleys. I'm afraid as well that the lesser expensive Gates belt was a poor investment.

^^ exactly what he said^^   I learned this lesson the hard way,Deere likes to spec their own belts and can cause some headaches if you don't use them. On a good note for they aren't that much more expensive and they do hold up quite well.

Always use an OEM spec belt on these, JD has special material and angles like most mentioned , there are aftermarket companies that replicate the exact JD belt but you need your JD part number to cross it with.

 

Gates belts are just standard size and are a crap shoot and not worth the hassle. The only time I recommend gates these days is for fan belts /light duty farm equipment and automotive applications, never Lawn mower equipment.

Lots of those little rod/wire belt keepers on my JD and you need them to keep belt on when not being used. They are PIA tho, need to come off when changing the belt. You keep those on yours?  BUT, that should only be for non-running belt I guess, not a powered one, so may not apply?

I tried one aftermarket belt and it ran for about 15 minutes before it destroyed itself. The Deere belt cost about $45.
