Machine control and GPS: agree the technology handover

A machine-control system does not necessarily transfer as a complete working service when the excavator or planer is sold. Hardware may be owned, leased or shared; software permissions and connected services can have different arrangements.
Define the package before writing “GPS included”. That phrase could mean anything from installed antennas to a supported system with a display, permissions and active correction service. A buyer needs the actual scope.
Separate hardware, services and project information
Start with an inventory of displays, receivers, antennas, sensors, controllers, radios, brackets and other identified components. Record each item's make, model, serial number where available and owner.
Do not assume everything fitted belongs to the machine owner. A survey subcontractor may own some equipment, or a fleet may move a display between machines. The plant identity guide helps distinguish component numbers from the base machine serial.
The software and service record should sit beside this hardware inventory. Caterpillar's VisionLink Productivity glossary describes grade-related hardware, connectivity subscriptions, remote files and GNSS correction services as separate features. It illustrates the possible dependencies; it does not establish what transfers under your contract.
Project files are another category again. A design surface or site survey may contain information owned by a client or contractor. Its presence on a device is not permission to pass it to the buyer.
Build a technology handover register
| Item or dependency | Ownership and evidence | Proposed handover | Confirmation needed |
|---|---|---|---|
| Display and receiver hardware | Purchase, lease or fleet record | Included, retained or returned | Exact items and identifiers |
| Installed sensors and controls | Build or installation record | Part of stated machine package | Compatibility and completeness |
| Software permission | Contract or supplier record | Transfer proposed or new arrangement needed | Written supplier response |
| Correction or connectivity service | Account holder and contract | Buyer establishes own service if required | Availability, transfer and cost scope |
| Machine configuration data | Supplier or installer record | Agreed export or retained record | What the buyer legitimately needs |
| Site and customer files | Information owner and permissions | Retain, return or remove by agreement | Authorised handling and completion evidence |
Use this register to expose questions, not to answer them by assumption. “Awaiting supplier confirmation” is a legitimate status.
The industrial software handover guide covers the difference between possessing a technical key and having permission to use software. That distinction applies here even when the screen still starts normally.
Avoid stripping value by accident
A rushed sale can remove a display that the catalogue promised, leave a retained machine without shared hardware, or erase configuration information that a competent installer needs. Resolve ownership and retention decisions before instructing anyone to remove equipment or clear data.
Ask the supplier or qualified installer what the proposed package requires. Get a written scope for any authorised removal, account change or data-handling work. Keep the commercial agreement and technical work aligned.
If a system has not been assessed recently, distinguish visible hardware from verified function. Do not promise positional accuracy, current calibration or readiness for the buyer's next project based on a historic installation invoice.
Describe the package that will leave the site
A precise offer might state that named hardware is included, while a connected service requires the buyer's own arrangement. Another sale may exclude the removable display entirely. Either can be understandable if the description, photographs and agreement match.
For a road planer, put this technology schedule beside the cutting-drum inventory so neither part of the package is lost in a general machine description.
Contact UK Auction Group with the register when discussing the sale. It helps define what can be valued and catalogued, while supplier confirmation settles transfer questions before the buyer expects a service that the equipment sale cannot provide.
