Mini Super Z has the shakes

[joyson]

I have recently purchased a mini super Z 52". The mower has about 10 hours and the front casters shake very bad nearing top end transit speed. I have checked all bolts and all is well. Anyone seen this problem? What is the correct PSI for the tires?

Thanks

You want to be running between 8 to 12 PSI in the front tires from my experience.
You can also tighten the caster arm pivot bolt to increase the tension on the swiveling of the caster arm.
I believe you will find this to take care of the problem.
If it still persists, take the unit back to your dealer.
