EricF 589 #2 Posted June 1, 2019 The serial number on a 520H is usually on the fender pan under the left edge of the seat. At least it is on mine. Electric PTO clutch? The 520H uses a manual PTO clutch which is adjusted with a trunnion on the rod connected to the PTO lever. If your PTO is electric then maybe your engine was replaced at some point? 2 Share this post Link to post Share on other sites
