Nolle’s Polyculteur design quickly passed from being a prototype to being manufactured commercially in France, and by 1958 a photograph of the Mouzon- Fig, 3-1: Polyculteur “lkger” with three seeders,Senegal, 1955. (Photo: Jean Nolle). ,i. : ‘,,‘:- I. 1. / I. Nolle Polyculteur in action in Senegal had appeared in’ the journal Agronomie Tropical (Labrousse, 1958). At the same time as this early work on wheeled toolcarriers, Nolle while working in Senegal also designed some cheaper intermediate type of tdolframes known as the Haue Saloum and later the Ariana.
Although more intermediate implements have been made in the past twenty-five years than wheeled toolcarriers (about 15 000 Ariana-type implemeqts compared with 10 000 wheeled toolcarhlers), they have not had either the adoption successof the simple toolbars (over 350000 Houe Sine type toolbars sold worldwide), nor the promotional efforts that research centres and development agencies have given to the wheeled toolcarriers. A certain small element of confusion relates to them in national statistics, as they are sometimes included with the wheeled toolcarriers and sometimeswith the simpler toolbars.

Wheeled toolcarriers appearedmost suitable, and severaldesignswere evaluated in 1975 (ICRISAT, 1976). ICRISAT did not attempt to re-invent the wheeled toolcarrier, but rather evaluated a variety of preexisting models, including the Kenmore (UK), the Otto Frame (India), the Polyculteur (Senegal) and the Tropiculteur (France). The preferred designwas the Tropiculteur, manufactured in France by Mouzon, and the 1975-1976 ICRISAT Annual Report contained three photographs of this toolcarrier looking remarkably similar to present-day models.
