Do you need to pull your ragwort?? if you've several paddocks couldn't you get them topped with the toppings baled & removed, and then spray the regrowth? Fertilizer or lime as needed after topping would help the grass come in stronger & crowd out the ragwort too.
Cutting is not recommended. Although it may reduce seed production, it can promote perennialization of ragwort, i.e. it will come back the following year more vigorously.
Should also bear in mind, until the plant has died off completely with no evidence of its presence remaining, any remnant will become palatable to livestock.
Rabbit scrapes, mole hills, poached and bare areas of soil, imported soil, etc, all provide ideal conditions for ragwort. Fertilising and lime may help, but I'd also be inclined to consider over-seeding where conditions dictate.
