OPERATING THE LOADER

OPERATING THE LOADER

The loader should be operated with the tractor engine
speed depending on the application and the operator's
level of experience. Excessive speeds are dangerous,
and may cause bucket spillage and unnecessary strain on
the tractor and loader.
When operating in temperatures below -1

(30

), run

the tractor engine below 1200 rpm until the oil
temperature exceeds -1

(30

).

The following text and illustrations offer suggested loader
and tractor operating techniques.

To reduce the possibility of roll over:

A

It is not recommended that the loader be
attached when operating another implement on
a hillside.

A

When operating the loader in rough terrain, remove
the mower to avoid damage to the mower.

FILLING THE BUCKET

Approach and enter the pile with a level bucket.

Ease control lever toward you and then back to rollback
and lift the bucket.

The rollback and lifting of the bucket will increase
efficiency because a level bucket throughout the lifting
cycle resists bucket lift and increases breakaway effort.

A

Do not be concerned if the bucket is not completely
filled during each pass. Maximum productivity is
determined by the amount of material loaded in a
given period of time. Time is lost if two or more
attempts are made to fill the bucket on each pass.
