My proublem is the tractor want hold its ground speed . I adjust the friction washer from time to time an it helps but its a fine line between to tight an to loose . I was wondering thats not suppose to be a special washer is it with some kind of friction material on it ? I know its not going to maintain its speed when the terrain changes say from level to a incline . But it just gradually slows down unless you constantly keep your hand on the lever . An it does something else when it crest a hill an starts down it will pickup quiet a bit of speed before it catches its self an starts to hold back . I usually just pull the lever back an catch it before it takes off, but is this normal ?

It is a friction washer and is part #4 in the below diagram. A lot of times these seem to somehow either ware or are lubricated at some point and this will cause the the hand lever to back down on its own. There also is a specific torque that the lock nut is set to but I don't have that in front of me at this minute.
You can find these parts diagrams as well as the owners manual at Toro.com or at the link I will put at the bottom of the diagram.
Also sometimes when they speed up going down hill it can be from a rear hub that is loose and they can freewheel a little until the hub locks again against the woodruff key. My 520H did this and I ended up having to replace the hub on one side as it must have been that way for awhile.
One last thing is that you should check all of your linkages for proper travel and if there is play in them it is most likely because the nylon bushings are worn or missing. Its strange how one little bushing can create such havoc but it can.
When you look your tractor up it will make it a lot easier if you have your model number and the serial number as well. That way you don't have to go through the entire list to find it.
Best of luck.
