Operating A Loader

The loader should be operated with the tractor engine running from 1700 to 2200 RPM. Excessive speeds are dangerous, and may cause bucket spillage and unnecessary strain on the tractor and loader. When operating in temperatures below -1 degrees Celsius (30 degrees Farenheit) run the tractor engine below 1200 RPM until the oil. temperature warms.

When operating the loader in rough terrain, remove the mower deck to avoid damage.
Basic Loader Functions

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 effciency because a level bucket throughout the lifting cycle
resists bucket lift and increases break out forces.


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.

Lifting the Load
When lifting the load, keep the bucket positioned to avoid spillage.

To avoid serious personal injury do not attempt to lift bucket loads in excess of the loader capacity.
Before raising the bucket to full height, make sure the tractor is on level ground. If not, it may tip over
even if the tractor is not moving.
Warning

Carrying the Load
Position the bucket just below the level of the tractor hood for maximum stability and visibility, whether the bucket
is loaded or empty.Use extreme care when operating the loader on a slope. Keep the bucket as low as possible. This keeps the bucket
and tractor center of gravity low and will provide maximum tractor stability.

Carrying

Warning!
To avoid serious personal injury:
Be extra careful when working on inclines.
When operating on a slope, always operate up and down the slope, never across the slope.

When transporting a load, keep the bucket as low as possible to avoid tipping, in case wheel drops in a rut.

Dumping the Bucket
Lift the bucket just high enough to clear the side of the vehicle. Then, move the tractor in as close to the side
of the vehicle as possible, and finally dump the bucket.

Lowering the Bucket
After the bucket is dumped, back away from the vehicle while lowering and rolling back the bucket.

Operating with Float Control
During operation on hard surfaces, make sure you 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.
 
The float position will also avoid mixing of surface material with stockpile material. The float position will
reduce the chance of surface gouging while removing snow or other material, or when working with a blade.



Loading from a Bank

Choose a forward gear that provides a safe ground speed and power for loading.
Excercise caution when undercutting high banks. Dirt slides can be dangerous. Load from as low as possible for maximum efficiency.

Note:
Loader lift and break-away capacity diminish as loading height is increased.

Side cutting is a good technique for cutting down a big pile. Wheel width should not exceed the bucket width for
this procedure. If the pile sides are too high and liable to cause cave-in, use the loader to break down the sides until a slot
can be cut over the top.


Another method for large dirt piles is to build a ramp to approach the pile.

It is important to keep the bucket level when approaching a bank or pile. This will help avoid gouging the work area.

Peeling and Scraping
Use a slight bucket down angle, travel forward, and hold the lift control forward to start the cut. Make a short cut
and break-out cleanly.

With the bucket level, start a cut at the notch approximately 2 in. deep. Hold the depth by feathering the
bucket control to adjust the cutting edge up or down. When the front tires enter the notch, adjust the boom
cylinder to maintain proper depth.

Make additional passes until the desired depth is reached. During each pass, use only the bucket control while
at working depth. This will allow you to concentrate on controlling the bucket angle to maintain a precise cut.

Loading Low Trucks Or Spreaders From a Pile
For faster loading, minimize the angle of turn and length of run between pile and spreader.

Backgrade occasionally with a loaded bucket to keep the work surface free of ruts and holes. Also, hold the lift
control forward so the full weight of the bucket is scraping the ground. Use the heel of the bucket.

Backfilling

Approach the pile with the bucket flat.

Poor operating methods will move less dirt and make it more difficult to hold a level grade.
Do not use the bucket in the dumped position for bulldozing. As shown above, this method will impose
severe shock loads on the dump linkage, the bucket cylinders and the tractor. Its the most common way of damaging the loader.

Leave dirt in the bucket because dumping on each pass wastes time.

Operate at right angles to the ditch. Take as big a bite as the tractor can handle.

Leave dirt which drifts over the side of the bucket for final cleanup.

Pile dirt on the high side for easier backfilling on a slope.
