If their new machines are like their old machines, they are pretty damn decent. I have an '86 TB16 (back when they looked like Kubotas-orange) and it has been just about beat to DEATH but still runs/digs like a 3100 pound gopher. Mine has oddball (sort of like british jic) fittings that I have gradually been switching to nptf female swivel. The pins were all metric, too, as well as the cylinder bores.
I would expect if the hydraulic, and leverage engineering is done well, it's pretty hard to build a bad machine (though it apparently does happen) but the triple pump right off the engine is the way to go. That way the systems don't rob from eachother. I have seen other machines that were not set up this way (!!!
). The weak link will always be the hoses, then the pins, then the tracks IMO. Basically wear items.
By the way, I specifically sought out a non zero tailswing machine for better stability and digging force. They definitely have their advantages. I wish mine had the pop out tracks and folding blade
but I can still sneak through a 36" gate (34" wide) And one last thing- Tak's are common RENTAL machines- I suspect that speaks somewhat to their durability. Mine lived most it's life as one. Nothing gets beat like a rental machine. (right?)
