New John Deere

Hydraulic Coupler

for Compact

Excavators

Switching buckets has never been easier with the new

John Deere hydraulic coupler (16GE23) for compact

excavators.

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

coupler.

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.
