Dear All,

I am an engineer from Greece, we have a Manitou MH25T-4 for service in our workshop. The 4-wheel drive is not working, as soon as one wheel is free to spin, all the power goes to that wheel. Any ideas what might be faulty?

We lifted the rear end, and the two rear wheels were turning, but the front wheels no power. Also the button for differential lock is not doing anything.

Any help will be highly appreciated.
