Cat 320 to 325 specifications

Current 320 and 320 GC equipment differ beyond the power column

The current 320 and 320 GC share a C4.4 engine designation, but the manufacturer's equipment lists distinguish twin-turbo and single-turbo versions. Their control and technology packages also differ. An older320B electrical account in the retained forum references is not evidence of the wiring or fitted controls on either current machine.

320 grade assistance and payload features have separate purposes

The current 320 publication distinguishes Grade Assist, which helps control digging movement, from Payload, which estimates the material being handled. Its Advanced Payload upgrade adds reporting functions. Buying a machine with basic Payload does not establish that electronic ticketing or the expanded reporting package is enabled.

The manufacturer also distinguishes a factory Grade 3D Ready hardware package from the software activation needed to use Grade with 3D. A receiver or display visible in sale photographs is insufficient proof that the required license is included.

Payload's estimate is not a legal-for-trade weighing result. Retain the manufacturer's restriction when using a loading estimate for production records. The same publication excludes certain automatic boost functions from the Super Long Reach configuration, so the front arrangement matters when checking a feature list.

Manufacturer 320 07H publication: engine, Payload/Advanced Payload, grade activation and long-reach restrictions

The 320 GC lists its own power modes and attachment circuits

The 320 GC has two selectable power modes. Smart mode matches engine and hydraulic output to digging conditions. Its automatic idle and preset idle-shutdown functions address time without work.

Those features do not establish that it includes the 320's grade and payload equipment.

Its equipment list names a two-pump attachment-control arrangement with one-way and two-way high-pressure flow. The actual attachment's return and control requirements still need matching. A pump's maximum flow figure alone cannot identify the fitted connection or correct attachment setup.

Region and front equipment affect an offered 320 GC

The current GC publication distinguishes long and medium undercarriages by destination market. It also gives different regional counterweights and seat arrangements. Match the country specification and installed components before applying its published weight to transport planning.

The same list restricts SmartBoom to Europe and identifies the narrow configuration as a regional option. Neither feature follows automatically from the GC badge. Its reverse-running electric cooling fans and ground-level inspection points are maintenance features to check on the individual machine, not proof of its service condition.
