    On grass while mowing my Super Z is fine but while transporting on asphalt the front left tire begins shaking like crazy after about 20yds any suggestions? :confused:

    grease your front casters and wheels. your bearings might be loosening up or going out. how old is the mower?

    Every Super Z I have ever owned did this until I let the air pressure down to 8 lbs. This squats the mower and puts more tire on the ground, that will stop it, let us know. The Super Z will fly compared to other mowers and that makes it more pronounced but there is nothing wrong, just let some air out.

    This also make it ride a lot better, I can tell the difference in 10 lbs. and 8 in the ride.

    We had that problem with a walk behind mower.Solved it by changing the bearings in the front wheels and the bushings in the front casters.

    You can set all 4 at 8 lbs. and you want believe how much better it will ride. I have never had any problems at 8 lbs. except once mowing a road ditch I pushed the tire loose from the rim and lost the air. This is once in hundreds of hours use.

    This one is easy. Lift the front end and tighten the castle nut on top of the caster, you need to do this every so often for me its once a year. What happens is things loosen and stretch over time, just simple maintenance.

    It needs a front end alignment :laugh:

    This stuff is frustrating, my Wb's do it, too...
    I just deal with it, slow down a bit, heck.

    I won't let no air out, the deck will take a dump to ground level if I hit a nasty bump wrong.
