COUPLING UP HYDRAULICS

Consult the tractor’s handbook for correct installation of the supply and return connection.

Note that if the tractor is equipped with one or more quick release hydraulic couplings the PT5 supply and return hydraulic components may need to be rearranged to facilitate fitting to a variety of tractors.

The motor drain line must always be returned to a low pressure position i.e. Transmission plug.

Where no specific return connection is available and the transmission filter plug has to be used, an adaptor must be fitted which then allows the motor return and the motor drain to utilize a common return location.

Run up the machine and operate through its complete range of movements including the operation of the cutterbar drive. Check the tractor’s transmission oil level and top up if necessary.

You are now ready to proceed to the work site.

REMOVAL FROM THE TRACTOR

1.Select a firm level site.

2.Replace the stand leg to the park position with foot down.

3.Position the arms so that the motor is level with the bottom of the frame.

4.Raise tractor linkage to take the weight off the yoke. Where a common top link and yoke position is used, the yoke must be unbolted in the middle. If different top link locations are used, the yoke may be unbolted at the top.

5.Lower the machine to the ground and disconnect the three point linkage. Remove top halves of the yoke if still attached to the tractor.

6.Use chain to tie the hydraulic control valve back to the main arm. This will make it easier for subsequent coupling up.

7.Blank off hose ends or loop the hoses and join with coupling is available.

STORAGE

If the machine is to be left standing for an extended period of time, lightly coat the exposed portions of the ram rods with grease. Subsequently, this grease which becomes contaminated with dust and grit should be wiped off before the rams are next moved.

Liberally grease the cutterbar and replace the finger and knife guard. Remember to take caution and keep fingers away from the knife.

If the machine is to be stored outside, lay a piece of tarpaulin or canvas over the control valve. Do not use a plastic bag which could lead to rapid corrosion.
