Finally got our new mixer on Monday. Been waiting a few months for it to get here. It is a Trioliet 2000 LZK. We can now mix 17,000lb loads and that should save us about two loads a day. So it should pay for itself in a few years with fuel and labor savings. Sad to see the old 5144 Knight leave but it was time. The tub was wore through in several places and the front conveyer was about shot.
