Reemplazo de la correa de propulsión en tierra

a.Quite la chaveta hendida y el pasador de seguridad (fig.

18)del buje de la rueda izquierda. Desplace la rueda hacia afuera aproximadamente 4 cm.

b.Quite la cubierta de la correa, quitando dos (2) tornillo, una (1) tuerca hexagonal y tres (3) arandelas, de forma que la cubierta de la correa pueda quitarse del motor (fig.

18).

c.Afloje las guias de la correa (fig. 17)

d.Quite la correa vieja, sacándola primero de la polea tensora (fig. 17).

e.Coloque la nueva correa en la ranura de la polea de transmisión (polea grande) y en la ranura de la polea de motor (fig. 17). La correa deberá estar en la ranura, en la parte superior de la polea tensora (fig. 17). Note la posición de la correa con relación a las guias.

f.Apriete las guias de correa (fig. 17)

Reemplazo de dientes

Los dientes muy gastados dificultarán el trabajo de la cultivadora, que no cavará tan profundamente. Más importante es que los dientes gastados no pueden cortar y desmenuzar la materia orgánica tan eficazmente, ni labrar tan profundamente como los dientes afilados. Un diente tan gastado como éste (fig. 19) ha de ser reemplazado.

Para mantener el singular rendimiento de laboreo de esta máquina se han de controlar los dientes en cuestión de afilado, desgaste e inclinación, especialmente los que están junto a la transmisión (fig. 20). Si el espacio entre los dientes es superior a 9 cm, deberàn ser reemplazados o enderezados.

Los dientes nuevos han de ser montados como muestrà la figura 21. Los borders afilados de los dientes girarán hacia atrás, visto desde arriba (fig. 21).

¡IMPORTANTE!

No trate de manipular nunca con el regulador del motor, que está ajustado en la fábrica a la velocidad correcta del motor.
