I am trying to tune my Kubota L245 F (2wd). It does not have a FEL. When I have the bush hog on and slightly lifted, I find it difficult to turn the tractor (have to use the brakes). When the bush hog is up, the front tires mainly slide (especially if on a slight uphill). I have one slab weight on the front. Do I need more weight or is this normal with a bush hog on such a small tractor? How much weight more should I add? Any cheap way to add homemade weights to the front or do I need to buy them? Thanks for the advice.
