Hi All. Can you all help by identifying my machine? It has no ID plates at all. It has a 3 cyl Perkins and there are two Hydraulic tanks in the bottom of each rear corner. The unit has no obvious leaks (I have repaired one or two) and I have serviced the steering unit. Attached is a few pics. My problem is that after 30mins or so the unit will slow down and struggle to turn. Once the unit then cools it works again fine. It has tbar control on left side. Thanks
