I adopted a 1320 hydro 4 years ago. It's got pretty light duty mowing about 1/2 acre weekly in season. Ever since I got it, reverse has been suspect. Always slower and going backwards up any kind of incline at all is a no go. The owner's manual says that the hydro is sealed and must be serviced by a dealer. I've searched the web and can't find anywhere where this issue is addressed. I'm looking for some easy checks to do before I just dive into it.
It still operates, just reverse is nearing unuseable. Any tips appreciated.
On my 1320, the final link was sintered* metal and it splintered. And it sticks down below the rear axle so it's possible to damage it. When it broke off, it was no go, forward or back. The replacement was welded steel which is far sturdier.
On my 1320, reverse is slow but does still work after many years of use and abuse. Keep us posted. Photos too if you tear it apart.
