Hi there MTB345.
We bought a terex pegson jawcrusher in -99. Sent it to Kosovo and it worked 24/7 for a year, then slowed down to 12 hour shifts for another year.
I've got it in my yard now, and it still works well.
2005 we bought a maxtrak 1000, had it with us to Afghanistan, it runned ap 600 hours in 4 months.
Now we have bought 2 maxtrack 1000sr, so we got 4 Terex in our park.
I have nothing bad to say about them.
The Metrotrack from -99 is underpowered because we got the "wrong" engine, a cummins, with to few hp.
We have, as u understand, very good experiense with the Terex pegsons.
And the new ones with Cat engines has enough hp. Bether that way, you get a longer life on the engines and it runs easier and on less fuel.
What spesific modell are you looking at by the way?
There is a video of our maxtrak working in afghanistan on youtube, search for mktef.
