Grille arrangement for a drive unit enclosure

An agricultural applicator, comprising:

• a drive unit supported on a wheeled chassis assembly;
• a bulk storage tank mounted on the wheeled chassis assembly;
• an enclosure configured to receive the drive unit, the enclosure having a rearward end that defines an opening located between the drive unit and the bulk storage tank;
• a grille arrangement configured to be mounted in the opening of the enclosure, the grill arrangement comprising:
• a screen;
• a frame mounted with the screen, the frame including a first strut connected by at least one movable latch assembly to the enclosure, and a second strut opposite the first strut, the second strut generally vertically aligned and comprising a first linear portion aligned at an obtuse angle relative to a second linear portion in top plan view, wherein the screen is attached at the first linear portion.

A method of mounting a grille arrangement in an opening of an enclosure for a drive unit of an agricultural applicator, the method comprising:

• providing the grille arrangement in a closed position attached in the opening at the forward end of the enclosure, the grille arrangement including a grille screen mounted in a frame and positioned in general alignment with a U-shaped vertical support strut located at the forward end of the enclosure, the frame including a first portion aligned at an acute angle relative the forward direction of travel and a second portion aligned perpendicularly to the forward direction of travel, wherein a junction between the first and second portions of the frame is engaged against the U-shaped vertical support strut;
• moving a latch mechanism so as to release a most rearward end of the frame and mounted screen;
• pivoting the screen at said junction of the first and second portions of the frame in a forward direction to a first partial pivot position relative to the forward direction wherein the second portion of the frame is in general perpendicular alignment with the forward direction of travel;
• and
• sliding the frame and screen in a transverse direction with respect to the agricultural applicator through a notch in the U-shaped vertical support strut, releasing the screen and frame.
