“…In Brazil, there are 4.4 million family farms, which are 84% of rural properties and produce 38% of the gross value of agricultural products and 50% of the food for the Brazilian food basket (MDA, 2018). There are few tools, implements, and machines meant for this sector of agriculture (Stefanello et al, 2014;Vianna et al, 2014). Through public policies, the Brazilian government has provided family farmers with subsidized credit programs, including the National Program of Sustainable Family Agriculture (PRONAF) of the More Food Program (Programa Mais Alimentos), for the acquisition of agricultural machinery .…”

“…Equipment that considers the needs of family farms must be developed (TEIXEIRA et al, 2009;ROMEIRO FILHO, 2012). Of the few initiatives that have been introduced (AREND et al, 2005;TEIXEIRA et al, 2008;ROMEIRO FILHO, 2012;VIANNA et al, 2014), some were mechanical (FRABETTI et al, 2011) and others were manual (MOLIN & D'AGOSTINI, 1996) punch planters that use human force, require no tillage, and have a systematic design methodology (STEFANELLO et al, 2014). These models include the Phases Model, which employs informational, conceptual, preliminary, and detailed design phases (BACK et al, 2008;ROZENFELD et al, 2006).…”

“…A metodologia fundamenta-se no Modelo de Fases, empregado na geração de produtos agrícolas como por exemplo, na estrutura funcional de uma semeadora de acionamento manual (STEFANELLO et al, 2014); na estrutura funcional de um encanteirador e depositor de fertilizantes (CUSTÓDIO et al, 2018); nas especificações para o projeto de um mecanismo aplicador de calor (SPAGNOLO et al, 2018) e no projeto conceitual de máquina para o controle de plantas espontâneas pela aplicação de calor de Spagnolo et al (2019).…”
