I picked up some used weights from a Bobcat dealer. They are the type that hang on a bracket. Each one weighs about 38 lb. I made my own bracket to hang them on front of my 2615HST pictured. Check with any tractor or equipment dealer in your area. They may have some used weights that you can adapt to fit your 2015. Mine have been in place for about 3 years now and do help in winter.
