Grouser rise height is the height of the shoe grouser tip above the ground when:
1 – The machine is on hard flat surface such as concrete, and…
2 – The grouser is aligned directly under the center point of the idler or idler shaft.
3 – Where the grouser rise height is too low, this will cause the front/Rear idler to load the weight of the machine on the Grouser bar directly below the Idler.
