Well, technology has changed a lot since the start of the company, right after WO2. The first developped machines (hay loader, Acrobat rake, fertiliser spreader) were all drawn by horses and driven via the wheels. From the fifties onwards,  the machines were tractor driven and powered directly via power take off axle of the tractor. In the sixties also the first self propelled machines were developped (combine harvester-see seperate post, pistenbully, LelyTrac-see seperate post, tractor). The first machine which worked with computer technology was of course the Astronaut in 1993. At that time the computer technology was so primitive and slow that calculating a sinus of a angle (needed for determining the teat position via triangulation), could not be calculated fast enough but needed to be looked up in a table. We now live in the are of artificial intelligence (AI). The Zeta calving detector would not possible without AI. More applications of AI can be expected!

was there ever a big change in the brand? like the logo's or images?

Actially there haven't been big changes in the brand since the first machine manufactured and sold by Lely (1958). All products are/were basicly always red with a small exception of the prefab houses and the products of the Lely-Dechentreiter factory during the sixties. From the beginning on, the Lely-butterfly logo was used (trademark filed 1960). In 2008 this logo was incorporated in the oval logo together with the slogan ''innovators in agriculture''. This logo was later in 2018 this logo was slightly changed together with the present slogan. Till approx 2000 also a so called ''french lely'' was used as symbol. See below some nice examples: prefab house form around 1968 and a monstrous tractor, the MultiPower.

nice!
