Have a 435, everything was running good and machine just died. Only thing I found was a blown 15 amp fuse, the spot the fuse is in is labeled with a lock symbol. I replaced the fuse and everything works now except for the tilt for the bucket, it's like something is keeping the joystick locked out that will not allow it to tilt. Checked all the linkage, fuses and relays everything looked ok. Any suggestions. Thanks
