Good evening I am new to the forum so here goes my first question- I have a 620 ztrac John Deere zero turn mower- mower has been sitting for 3years because it stop moving- would not move FORWARD or BACKWARD- the mower has Hydro- gear hydrostatic hydraulic pumps- I just rebuilt both pumps- both pumps have all brand new internal parts- put everything back together- mower will move again- but it will ONLY MOVE BACKWARD- it will not move FORWARD- does any one have any idea why with all new parts- new fluid- new filter- new drive pulleys- mower will only move BACKWARD- help-Thanks
