John Deere 345GLC to 670G LC specifications

G-series selection starts with tail space and the digging front

The 345G LC is a reduced-tail-swing excavator, while the much larger 670G LC offers standard and mass-excavation fronts. Choose between those layouts by rear clearance, reach and the installed undercarriage. Their neighboring numbers do not describe successive trims of one machine, and a shared G suffix does not establish matching hydraulics.

The 345G reserves a pump for swing

Deere's 345G brochure describes three main pumps, including one dedicated to the swing circuit. Its separate pump-flow lines matter when comparing multifunction operation: a sum covering only the paired implement pumps leaves out that third circuit.

The same brochure identifies a coupler compatible with attachments available for the 300G LC. This is a named compatibility statement, not permission to transfer every 350G attachment. Match the particular coupler and attachment before making a purchase decision.

Its Isuzu engine meets the brochure's Final Tier4 specification without a diesel particulate filter. A DPF maintenance account from a different G-series excavator therefore does not identify this engine's service arrangement.

The 345G working-range drawing distinguishes maximum reach from reach at ground level. Its rear swing dimension is also separate from the front linkage's minimum swing envelope. Plan the obstacle clearance with the relevant drawing, not whichever radius is smaller.

The 670G transport stance is narrower than its working stance

The regional 670G/870G publication gives separate operating and transport positions for the 670G undercarriage. A transport-width entry cannot establish the stance used by its lifting chart. Confirm that the machine is configured for the intended operation before carrying a transport measurement into a lift plan.

The document also provides a disassembled shipping table for the base machine, side frames, counterweight and front components. That table describes separate loads. It must not be read as the weight or envelope of a complete excavator ready to work.

Standard and mass-excavation booms have separate arm combinations and working ranges. The shorter ME front trades reach for a different digging configuration. A headline maximum digging depth from the long arm cannot describe the ME setup shown elsewhere in the same brochure.

Finally, the regional publication cautions that illustrated options differ between markets. Its configuration-specific dimensions remain useful, but they do not establish the equipment supplied on a North American auction machine. Obtain that excavator's serial-specific documents before planning a move.
