    With the unit OFF check the tension of the trans belt, maybe just loose and slipping causing your slow ground speed.

    thanks for the info Med-checked the belt felt/looked good, same as my old ones --- the used mowers I have both have 2 holes in the top of the engine behind the air filter and the new one only has one these holes this and the fact that the new mower has a choke button are the only differences, just dont get the diff in speed-----I can put the older ones in 5th gear and they are flyin ---the new ones 5th speed feels like 3rd :confused:

    Ask your dealer if Graveley has had any "incidents".

    You know, someone who was stupid enough to run themselves over, and then smart enough to sue over it.

    Could be the reason for the change in speed.
