The seat looks like it goes back further than mine, (could be an illusion), and the joystick handle is black(mine is silver), ROPS has been removed, it has a plastic fuel tank(mine does too), the tunnel covers on top and on the left side footwell look like they have been removed, it has a spinner knob on the steering wheel (handy), it has the hydraulic quick attach like mine and it looks like the parking brake is in the off position. I cn see the throttle and choke levers to the left of the steering column, but what is that dark item to the right of the steering column? It also looks like it has the same round Kohler muffler that I have. The turf tires look like the tread is still pretty decent.
Did you see any leaks, damp spots? It is common to have some damp areas around the hydrdaulic reservior filler cap, as it is a vented cap. Just be sure to wipe it down and clean it before you open the hydraulic cap to check the fluid level. Also, I've found that my fuel tank cap will be damp if I fill it within three inches of the top and drive over rough terrain. Check all of the ball joints in the hydraulic ram ends to see if they are smooth and shiney and see if they move easily. And, since the tunnel is exposed, check the joints in there... the great big ones that hold the front and rear halves together and the little bitty ones in the treadle linkage. Good luck. Let us know what you think of it.
