Hi folks, I wanted to share my problem with you guys.I have a 2 .5 yr old Scagg patriot.52 inch cut 22 hp Kawasskiand 2 hydrogear 3100s.Recently the left drive has slowed by 2/3 .Only in reverse.The mower only has 170 hrs on it, out of warranty, of course.I changed the oil and drive filters at 90 hrs again at 150 hrs.There is no leaks, no noise and my fans are both in perfect condition.I wanted to see of anyone else has had problems this early in the drive life?
