New to the forum, 1st post. Hoping someone can help bc I’m close to saying the heck w it and selling my Kubota for something a different color. I bought my L3800 brand new in 2013. I use it just for mowing w a brush hog and a tiller for food plots. Only have like 300hrs on it. The issue started a couple years after owning the tractor but in the last few years has gotten to where almost every time I use it and go to engage the pto it makes a loud chattering noise. So I have to crawl under tractor and adjust the pto cable to try to make it tighter. This helps for a little while, maybe a few hours and then it starts to do it again. What is the deal here?
