High Hour Used TK TL150 - What to look for?

I am looking at a Takeuchi TL150 with 3900 hours on it. It will be used on my own property....so light use...primarily maintaining Motocross tracks.



For a high hour TL150...what danger signs and wear points should I worry about?

Tracks - should have been replaced 2-3 times

Wheels - perhaps replaced 1x Sprockets - Should have been replaced at least once..

Pivots - I have a machine shop...so I can fix this sort of stuff pretty easy.

Pump and Drive motors? I have heard a few horrors about one going down...and metal shavings totaling the whole system...

Engine...I have heard the Yanmar should be good for 6000+ hours if maintained properly. Blue or white smoke bad....Black not so bad.



Any advice is appreciated...
