Attached is a picture of my S-470D Buck. It is not pretty to look at, has been rolled on three separate occasions. It is still a beast! My Dad bought it new. I also have a Mitsubishi FD1450D which looks a lot better and does the mowing that my Z cannot get to. Does your 160 crank and run OK and does the 3 point hitch work?
Knowing the history of a machine since new is an advantage- How it is run and maintained has a big effect on longevity. I don't know the history of the 160, so I have to deduce from the evidence, and the evidence seems to indicate that the owner(s) were not too concerned with maintence. It is probably a tribute to the machine that it does, in fact, run at all.
It cranked and started when I went to look at it (I intentially arrived earlier than I had said I would and checked to be sure it was a cold start).
The 3 point rose and fell with me standing on the arms, but there was nothing heavier around to check it with, so i don't know if it will raise a heavy load or hold it.
The only other thing I noticed is the differential lock pedal does not seem to move. Might be rust on the pedal linkage, or might be internal- don't know at the moment. A non-functioning differential lock would not be a big deal, in my opinion, since one can always brake the spinning wheel, but it's another sign that the machine has been ignored. As is the fact that the brake pedals are not lined up, and lining them up is a 10 minute job adjusting a few nuts. Except that the nuts and rods are badly rusted now from disuse.
Speaking of rolling, one thing that i liked about this one is it had wide turf tires on it. My ground is hard & rocky, so ag tires probably don't get that much more traction than turf tires, and the wider stance is nice since i have a few hills. The tires are not in that good of shape, however.
What is that steel angle thing behind the seat?
