Front Linkage Options. The Reach Boom
allows excellent all-around versatility
and a large working envelope. It can be
equipped with the following two sticks: • R2.9B1 – performs well in a mid-
range working envelope
• R2.5B1 – a good match when the job
requires a larger bucket or a hammer
Bucket Linkage. The power link
improves durability, increases machine-
lifting capability in key lifting positions
and with the integrated lift-eye it is
easier to use than compared to the
previous power link. The lift eye also
gives you the optimum lift performance.
It allows you to lower the load point,
which maximizes the use of the boom
cylinders.
