How to adjust the swash linkage?
Swashing is adjusted on
the rear transmission Use an 17mm spanner to lossen
the locknut
After that turn the nut with 17mm spanner to right or left to get the right
adjustment. The speed on the rear wheels should be 101%-105%
quicker than in the front.
Remember that you need to have one wheel on each axel in the air to do this
adjustment and mesure with an revcounter (laser) (when checking the swash
do the same as you do with PF21 to check)

Dynamic weight transfer
by articulated steering
•A
2= B (centre of the lower pivoting point)
• C= Xmm longer than B (and A2) = creating a dynamic in the pivoting point
causing the “dog-bone” lifting/raising the mid point of the machine 20-30mm

Benefits with dynamic “dog-bone”
when steering
• “Dog-bone” pushes / raises mid point up
• Positively effects the centre of gravity
- improves traction on front inner wheels
