Abstract
This research has been conducted in Padang City from April to September 2012.
Purpose of this study is to obtain a mathematical model of engine power tractors for
tillage tractors working at various speeds. This study was obtained from a mathematical
model involving variable engine power of tractors on soil tillage (P, watts), soil bulk
density (p, kg!m3
), tillage depth (d, m), soil tillage speed (V, m Is), and the acceleration of
gravity (g, m/s2
) in district Pauh is :
P. if I [p v' 1 = 0,5129 { If I [ g.d1 F2
•
8925 with I= 1,
and mathematical models based on the tractor enginr:;ower in district Kuranji is :
P. if I [p v' 1 = 0,6656 { If I [ g.d1 F "97 with I is 0,999.
