FILLING THE BUCKET Approach and enter the pile with a level bucket. Loaders with 1-lever control, ease lever back and toward you to lift and rollback the bucket. Loaders with 2-lever controls, ease both levers back to lift and rollback the bucket. The lift and rollback of the bucket will increase effi- ciency because... ...a level bucket throughout[...]

CARRYING THE LOAD Position the bucket as low as possible below the level of the tractor hood for maximum stability and visibility, whether the bucket is loaded or empty. Use extreme caution when operating the loader on a slope and keep the bucket as low as possible. This keeps the bucket and tractor center of gravity low and will provide maximum tr[...]

OPERATING WITH FLOAT CONTROL During hard surface operation, keep the bucket level and put the lift control in the float position to permit the bucket to float on the working surface. If hydraulic down pressure is exerted on the bucket, it will wear faster than normal. FLOAT The float will also prevent the mixing of surface material with stockpile m[...]
