Steering

[Lower Fosse]

Gentlemen: I have a compact tractor (Siromer) on which the steering geometry is incorrect. The steering arm offset angle is insufficient so that the tires scrub in turns, the outer is too sharp relative too the inner. At full lock the inner describes an arc of radius 4.9ft, the outer a radius of 8.1ft and the front wheel track is 34 inches. The wheel base is 50 inches. Does anyone know how to calculate the correct angle of each front wheel to describe these arcs without scrubbing and the angular offset of the steering arms to achieve this?
Thanks & regards

Hi. Welcome.

Sounds like you need an alignment. That should correct the situation.
