Draft Control - Roll Over Protective Structure (Rops) (Optional) - New Holland Boomer 45 Operator's Manual

Draft control - Roll Over Protective Structure (ROPS) (Optional)

The optional draft control lever (1) will be located in the slot
on the right-hand control pod, next to the position control
lever (2).
Set the draft control to the desired depth for the attached
implement by using the lever. Draft control is best when
using implements that operate in the ground, such as
plows, harrows, or cultivators. The amount of draft load-
ing on the implement will increase or decrease as the
working depth or the soil resistance changes.
To set the draft control, move the position control lever (2)
to its full forward position. Then set the implement draft
depth lower by moving draft control lever forward, or set
it higher by moving lever rearward.
Implement depth will be promotional to draft, depending
on the soil conditions. With draft control, the lift keeps the
tractive effort steady automatically.
You can limit the range manual draft lever operation by
moving and tightening the stop (3).
Combined draft and position control
You can use draft and position control together to oper-
ate in draft control but prevent the implement from sinking
excessively when soil conditions change. First, set the
draft control lever with the position control lever fully for-
ward. Then move the position control lever back until the
lift arms start to rise. The position control lever sets the
lowered position of the hydraulic lift.
Float operation
Move the draft control lever and position control lever fully
forward. The three-point linkage will now be free to "float"
or follow the ground contour, a feature useful for scraper
blades, etc.
Draft control lock out
The draft control will lock out by positioning lock out stop-
per, located on the top link bracket, in position (A).
Place lock out stopper in position (B) to allow the draft
control to function.
