High-tech backhoe loader
 John
Deere says it has introduced the first backhoe loader to feature a
completely integrated control system. The hallmark of the new 92-horsepower
410H is the company’s Total Machine Control system, which integrates control
for the engine, transmission, hydraulics, and brakes so the systems can
respond in a coordinated, efficient way to different job demands. In startup
mode, the 410H digs at the same speed as the 410G, but in “Fast” mode, it
will dig 30% faster and in “Slow” mode (for precision work) it digs 20%
slower. New automated features include return-to-carry which returns the
loader boom to travel height after dumping, and boom height kick-out, which
allows the operator to set the loader boom height to fit working conditions.

New toolholder system
Wirtgen has
adopted a new quick-change toolholder system for its large-volume milling
machines this year. The new HT11 features a much larger, stronger retaining
bolt than the previous HT3 system. The upper part of the HT11 completely
covers the bottom part, ensuring an even and tight fit between the two so
that when the upper needs to be replaced, the bottom part needs only minimal
cleaning. Also new, the bore in the bottom part is sealed against
contamination, optimizing performance and reducing the time required to
change parts.
