hey good idea however im located way out in the sticks here in the north and i need this tiller i best to try and find some online or close to the originals if i can! however again thats a good idea and will resort to that if i have to i did find and saves the old ones maybe theres a way i can redrill and shorten up the old ones?? I will give it a shot! And next time i travel to a big city for essentials i will bring the broken ones along to compare at one of the TSP stores,, also a friend told me this to actually break off a original Kubota one from japan its pretty tuff its like breaking a HEAT treat super strong Samurai SWORD!!!
