I have a 42" deck, #18422 mounted under a 1053. I am wanting to put this deck under a G12 with a 14 hp Tech replacement engine. According to the interchange guide it says to relocate pin in front bolster to higher position. I did no know there was two positions for the front bolster pin on this tractor. Is this a mater of jacking the front of the frame up, removing the bolster pin, raising the frame more and putting the pin in another hole in the front axle? Or is there something here that I am missing?
