Have Agricultural Machinery Inspected Before Purchase: Appraisal by the Expert

The purchase of used agricultural machinery such as tractors, combine harvesters, or forage harvesters carries significant financial risks. Unlike the car market, mechanical loads in agriculture are extreme. Hidden defects in the powershift transmission, leaks in the hydraulic system, or advanced wear on the axles are often difficult for laypeople to detect. A professional inspection before purchase primarily serves to minimize risk. An independent appraiser can determine whether the stated operating hours match the machine's actual wear pattern.

A written appraisal also provides a solid basis for negotiation. If defects are documented, repair costs can be precisely deducted from the purchase price. DIAVAG operates completely independently here. Since we do not sell vehicles and do not carry out repairs, our assessment remains objective. This sets us apart from workshop checks, which often have a vested interest in future repair orders. A BVSK-compliant appraisal is also an important document for financing through banks or for insurance contracts, as it establishes the actual market value at the time of inspection.

A key advantage of the DIAVAG service is mobility. Due to their size and transport costs, agricultural machines are difficult to move to an inspection site. Our appraiser comes directly to the asset, whether at the seller's farm, a construction site, or a trading location. In the regions of Hamburg, Berlin and Munich, we guarantee an appointment within 24 hours. This speed is particularly crucial at auctions or short-notice sales offers in order to secure the right of first refusal.

The mobile service saves the buyer time and logistics costs. On site, the inspector carries out a standardized workflow that takes under 15 minutes. Despite the short time on site, the depth of data is high, as calibrated hardware is used. The results are recorded digitally and forwarded to our senior inspectors, who sign and send the final PDF appraisal on the same day. This process ensures that you don't lose time and can make a well-founded decision immediately.

The technical inspection of an agricultural machine by DIAVAG follows a strict protocol. First, the vehicle's identity is checked using the vehicle identification number (VIN) and the nameplates in accordance with StVZO and FZV. A central component is reading the fault memory via the OBD2 interface or specific protocols such as SAE J1939, provided the machine supports this. Implausible parameters or past thermal issues can be identified here.

The inspection also includes:
1. Hydraulics and drivetrain: visual inspection for leaks at cylinders, hoses, and pumps, as well as a function test of the power take-off.
2. Chassis and tires: measurement of tread depth and inspection for cracks or damage to the carcass, which is a significant cost factor for large agricultural tires.
3. Body and paint: use of a coating thickness gauge to identify repainting, which can indicate accident damage or corrosion cover-up.
4. Documentation: standardized photo documentation records the current condition in a tamper-proof manner. Optionally, this record can be secured with a notarial hash on the Polygon blockchain to permanently guarantee data integrity.

Hourly billing or billing based on the value of the object is common in the appraisal industry, which often leads to unpredictable costs for the customer. DIAVAG breaks with this practice and offers clear fixed prices. The standard private price of auf Anfrage applies to standard agricultural machinery and construction equipment. For particularly high-value assets or complex machinery requiring more in-depth analysis, we charge the premium price of auf Anfrage. These prices already include travel within the region and the preparation of the BVSK-compliant appraisal.

For commercial customers, such as dealers or fleet operators, who require a volume of more than 50 appraisals per month, we offer individual terms. An API connection to existing Dealer Management Systems (DMS) is also possible here, to fully automate the valuation process. This price transparency allows buyers to firmly budget the appraisal costs without having to worry about additional charges. For us, independence also means financial clarity for the customer.

An appraisal is only as valuable as its legal robustness. DIAVAG relies on the highest standards to ensure that the documents hold up in inheritances, divorces, insurance claims, or legal disputes. Our appraisers are qualified according to the guidelines of the BVSK (German Federal Association of Freelance and Independent Motor Vehicle Appraisers). In addition, DIAVAG operates as an inspection body according to ISO/IEC 17020 Type A, which marks the highest level of independence.

Every appraisal is checked and signed by a senior inspector. This guarantees consistently high quality, regardless of which appraiser collected the data on site. In the event of legal disputes, the appraisal serves as objective proof of the condition and value of the machine. However, we note that DIAVAG does not provide legal advice. For specific legal questions regarding the purchase contract or warranty claims, you should always consult a lawyer or notary. The appraisal provides the necessary facts for their work.

Regulatory requirements for construction and agricultural machinery are steadily increasing. An important factor for future value retention is the EU Machinery Regulation 2023/1230, which becomes binding on January 20, 2027. This regulation places new demands on the safety and digital documentation of machinery. Anyone buying a used machine today should ensure it meets current and upcoming safety standards to avoid future decommissioning or costly retrofits.

DIAVAG is already preparing its appraisals for these regulatory changes. Similar to the EU Battery Passport for electric vehicles, which becomes binding from February 2027, we place great value on complete digital recording of all relevant data. This protects your machine's resale value in the long term. An appraisal that takes modern standards into account is a quality feature that can make a decisive difference upon later resale. We support you in making your investment future-proof.

We are often asked about the difference to organizations like TÜV, DEKRA, or GTÜ. These organizations primarily specialize in periodic technical inspections (HU) and safety checks, usually focused on cars. DIAVAG, on the other hand, covers seven asset classes, explicitly including construction and agricultural machinery, boats, and home battery storage systems. While an HU only confirms roadworthiness at the time of the test, a DIAVAG value appraisal provides a detailed analysis of the market value and overall technical condition, including well-founded photo documentation.

Another important difference lies in comparison to vehicle purchasing platforms or algorithm-based estimation services. These portals often aim to purchase the vehicle themselves or broker it to partners, which can limit the independence of the assessment. Algorithm-based services also do not carry out an on-site inspection but are based on statistical averages. DIAVAG, on the other hand, assesses the individual object on site. We sell no vehicles and no insurance. Our sole service is independent expertise, which guarantees the neutrality of the appraisal.

The process at DIAVAG is designed for maximum efficiency. In the first step, you request your appointment online or by phone. Thanks to our network in the regions of Hamburg, Berlin, and Munich, you receive confirmation for the on-site inspection within 24 hours. You don't need to move the machine; our appraiser comes to the location.

In the second step, the on-site inspection takes place. This usually takes less than 15 minutes, as our workflow is highly optimized through the use of specialized hardware cases. The appraiser collects all relevant data, performs the system diagnosis, and takes the necessary photos. In the third and final step, the data is evaluated at our headquarters. A senior inspector validates the results and prepares the BVSK-compliant PDF appraisal. You receive this by email on the same day. This gives you a legally sound document that you can use for the purchase, insurance, or financing of your agricultural machine.
