Detaching An Implement - MASSEY FERGUSON 410 Operators Instruction Book

Detaching an implement

WARNING: If two people are involved
in detaching an implement, great care
must be taken. When making any
adjustment to the hydraulic lift system
the person in the area of the linkage must stand
clear.
1. Select a level area as this will make detaching
much easier.
2. Lower the implement using Position Control (see
page 45), or where necessary, raise the implement
to fix parking stands in position then lower the
implement to the ground
3. Stop the engine and apply the parking brake before
dismounting from the tractor.
4. Unscrew the top link to remove the weight of the
implement and remove the pivot pin. Stow the
lynchpin, and then stow the top link in its clip.
5. Detach the lower links and stow the lynch-pins in
the links in the stowage points provided.
6. Open up the PTO shield and the shaft.
7. Disconnect hydraulic hoses and cap the ends.
Replace the dust caps on the control valve
couplings.
8. Start the engine and drive the tractor forward
before returning the Position Control to the
'Transport'' position.
Pressure relief valve
Avoid using the tractor hydraulic system in any way
which may cause the pressure relief valve (which is
internal), to discharge continually. This can be caused
by attempting to raise a load at the lower links, greater
than that which the system is capable of lifting.
Although the relief valve will prevent damage to other
parts of the hydraulic system, unnecessary discharge
must be avoided, as damage to the relief valve may
result in over heating the system and a reduction in
the maximum hydraulic pressure.
Safety chains
When towing implements on the highway, use a
safety chain (Fig. 71) with a tensile strength equal to
or greater than the gross weight of the implement to
be towed by the tractor. This will control and retain
the implement in the event that the hitch pin is lost.
After attaching the safety chain, make a trial run by
driving the tractor to the right and to the left for a
short distance to check the safety chain adjustment.
If necessary, readjust to eliminate tight or loose chain.
