lynnmor 7,815 #27 Posted October 12, 2021 My 520H Owners Manuals show 5.6 MPH maximum. My commercial zero turn has a maximum speed of 9.2 MPH and that really is a time saver. While I can't mow at top speed most of the time, there are many places like driveways where I can open it up. Share this post Link to post Share on other sites

Perhaps the tire diameter is different. My Owners Manuals are from 1991 and up. Share this post Link to post Share on other sites

I was aware that there was a size change, but I didn't check the working diameter. Later model 520H tractors have the 23x10.50-12 tires. It may be that the speed is the same in all years and the numbers may not be absolutely correct. Share this post Link to post Share on other sites
