Buying a tractor or construction machinery – agreements and inspection points

When purchasing a tractor or construction machinery, the price can be high while the legal and technical status of the object is more complex than with a standard vehicle purchase. The agreement should therefore combine clear identification with a structured inspection of the machine, documentation, and included attachments.

Tractor, motorized equipment, or unregistered machine?

Construction machinery may be subject to various vehicle and registration regulations depending on design and use. The buyer should therefore first establish how the object is classified and check registration details where available.

Operating hours and service history

The hour meter reading is often central to the valuation but should not be treated as a guarantee unless the seller explicitly warrants it. Document service logs, invoices, major repairs, filter/oil service, and known component replacements.

Technical inspection before the deal

Check cold start, exhaust smoke, leaks, engine noise, transmission/hydrostat, hydraulics under load, play in joints and hitches, brakes, tires or tracks, work lights, and safety features. For high-value items, an independent machinery inspection may be justified.

B2B purchases and private purchases require different risk assessments

The Sale of Goods Act (Köplagen) is non-mandatory and carries significant weight for both private individuals and companies when other rules do not supersede it. In B2B deals, the agreement should also address VAT, delivery, warranties, liability, operational downtime, and any financing conditions.

Common mistakes

• Specifying only the model and missing the serial/chassis number.
• Accepting hour readings without documentation.
• Failing to list all attachments in the agreement.
• Overlooking whether the machine is subject to financing or retention of title.
• Failing to specify whether the price in a B2B transaction is inclusive or exclusive of VAT.

Frequently asked questions

Must construction machinery be registered?

It depends on the machine's classification and use. Check current information with the Swedish Transport Agency for the specific object.

Is the hour reading binding?

Only to the extent the parties have agreed upon or the seller has provided a statement that carries contractual significance. Therefore, document what the seller actually states.

Should attachments have their own serial numbers in the agreement?

Yes, when available. It reduces the risk of disputes regarding which equipment is included.

Does the Sale of Goods Act apply between companies?

Yes, as a baseline for the purchase of personal property, but the act is non-mandatory and can be replaced or supplemented by the agreement.
