For such a small job, why not just rent a dozer for a week?

Not a bad idea, you know your costs and if it pops a motor, clutch, tranny, pump etc, it is not your responsibility. Take a vacation and have a ball!
I had an older 450B model for about 15 years. It worked OK but I did sink some dollars in it. When you look at the work I did with it, it did pay for itself. But if you only have a few small jobs and then intend on selling it, the rent thing makes sense.
You could buy the thing and easily have a major problem after a few hours. That is the risk when purchasing older used equipment. Dozers generally get worked very hard at numerous points along the way. The fact that the one you are looking at has stress cracks is evidence this one is no exception.
Repair costs add up real quick on any heavy equipment.
