Tools
The mower’s special design means that most repair and maintenance work can be carried out using standard tools.
Servicing of engines and hydraulic pumps requires special tools. These are listed in the service manuals of the individual manufacturers.
The mower (engine excluded) has mainly UNC or UNF screw/bolt/nut threads. Certain nuts have special stiffy threads for securing. It is vital that exactly the right size tools (i.e. imperial measurement) are used on these.
Those working on the mower must have ready access to socket wrench sets and open end wrenches of the following sizes:
•3/8"
•7/16"
•1/2"
•9/16"
•5/8"
•11/16"
•3/4"
The following are also required:
•Torque wrenches, 12 Nm - 110 Nm.
•15/16" socket for torque tightening of blade bolts.
•7/8" open end wrench or combination wrench for torque tightening of hydraulic lines.
•A set of small, imperial measurement, Allen keys.
WARNING!
If metric or other unsuitable tools are used, there is a danger that they will slip and cause personal injury. They may also damage the surfaces of the nut or bolt in such a way that tools can no longer get a firm grip.
