I have a Kubota L3130 4WD with the 12 speed GST transmission. Does anyone have any knowledge of what is involved in mounting a grading blade underneath the tractor, between the front and rear axles?
Why, what is it you are wanting to grade? You could alsways get a frame mounted front plow/blade with "down pressure" that would fit below your loader and bucket. Doesn't look like you have much room for a grader blade under your bota.
Those grader blades are handier than a shirt pocket. If you got the capabilities to mount it, you won't regret it.
