4.0. Connecting the Straw Harrow to the Tractor
The Claydon Straw Harrow mounts to the 3 point linkage of the tractor on CATIIIN linkage
pins, you will need to use the correct size balls (not supplied) to fit the pins. The hydraulic
services should be paired together in spools for the main folding ram and the tine angle
adjustment rams (Figure 3).

Once the Straw Harrow is attached and at the correct working height, the top link should be
set at an angle in which the convergence point between the upper and lower link arms
should fall at the front axle (Figure 5). This can be achieved by altering the top link pin
attachment points on the tractor and the Harrow. This ensures stability and the mass of the
implement is used correctly.
