New John Deere
Switching buckets has never been easier with the new
John Deere hydraulic coupler (16GE23) for compact
Operators are no longer required to exit the cab to
switch buckets, so site clearing can continue with high
productivity and minimal interruptions. The hydraulic
coupler is designed for 35G, 50G and 60G excavators,
and is compatible with the ever-expanding lineup of
John Deere Worksite Pro attachments.
The hydraulic coupler offers many key features
that help drive additional productivity from an excavator.
Most notable is the wedge bar locking system that com-
pensates for wear and keeps the coupler joint tight.
The wedge-style bucket pickup enables compact
excavators to maintain breakout forces by keeping weight
down, and operators can easily switch to other attach-
ments, such as hydraulic hammers, with an adaptive
bracket. The coupler is activated using a rocker switch.
Once activated, curling the bucket unlocks the
What's New in Plant & Equipment
Groundforce unveils SheetMaster
Handling and installing trench sheets is now quicker,
more controllable and safer thanks to SheetMaster, the
new three-in-one revolutionary trench sheet handling
tool from Groundforce Shorco.
SheetMaster is a multi-function sheet handling and
installation attachment that connects to an excavator
boom via a standard quick-hitch coupler.
Designed to replace three regularly-used trench sheet
handling tools on site, each of which has its limitations.
With this new attachment, there is no need for pitching
or quick release shackles; used to lift the sheet into the
vertical for positioning, driving caps to protect the sheet
from damage or extraction chains to pull the sheet
out of the ground.
The SheetMaster comprises a pair of slotted legs
which engage over the top of the sheet. A spring-load-
ed pin located on the upper leg engages with the
shackle-hole in the sheet to hold it firmly in place.
With the sheet secured, the operator then lifts it
into the vertical and, using the excavator’s hydraulic
controls, “pitches” the sheet ready for driving.
Once the sheet has been toed-in by the excavator,
the spring loaded pin is released by pulling on a lan-
yard which then allows about 300 mm of vertical
movement, allowing the SheetMaster to be used as
a hammer to drive the sheet to depth or refusal.
Traditionally, a heavy steel driving cap is placed
over the top of the sheet; not an easy or safe operation
if the sheet is several metres up in the air
Again, enhanced safety is the main benefit here,
although savings in time and labour are also factors.
When it comes to extracting driven sheets at the end
of the job, SheetMaster is simply placed over the top of
the sheet and the pin re-engaged with the shackle-hole.
It is then a simple matter of pulling the sheet out of the
ground with the excavator.
