Control Valve Relocation:

The 2001 Machete will reflect a change in the way some of the components are mounted to the tractor. New Machete units received from the factory, or assembled by dealer after S/N MB21- 01572 & UP or MB24-01245 & Up will have the control valve in a new location. It will no longer be mounted on the frame. The Control Valve will be located under the front pump cover in the front of

the tractor. This change was made to better protect the Valve and its components from debris and

other possible damage.

As you can see in figure 1,

 

 

 

 

 

 

 

 

 

the valve is fastened to a plate

 

 

 

 

 

 

 

 

 

 

 

 

 

 

that is mounted to the units hy-

 

 

 

 

 

 

 

draulic tank. The Pressure Filter

 

 

 

 

 

 

 

was relocated to a bracket on top

 

 

 

 

 

 

 

of the tank. Both the Pressure

 

 

 

 

 

 

 

Filter and the Pump Filter are

 

 

 

 

 

 

 

accessible and can be changed

 

 

 

 

 

 

 

with minimal effort. Sepaarate

 

 

 

 

 

 

 

hose exstension were used to

 

 

 

 

 

 

 

extend the hose reach to the front

 

 

 

 

 

 

 

of the tractor. If a hose connec-

 

 

 

 

 

 

 

tion is not easily accessible, then

These Changes were

 

 

 

 

 

 

 

made to better protect the valve

 

 

 

 

 

 

 

and its components. These

 

 

 

 

 

 

 

changes will only be seen on the

 

 

 

 

 

 

 

new units after Jan. 2001 and is
