I was wanting to mount an 18442 deck under a G12. The chart says "Req.relocate pin in front bolster to higher position." Checked with another long time Bolens collector and we could not figure out what they meant. I proceeded to change the deck over. Removed all the brackets off a 1053 and installed them on the G12. Everything went on OK, deck is mounted and raises an inch higher than it did on the 1053. Used a single belt pto which has a smaller pulley, which turns the deck faster. Works great. If you mounting a deck under the G series Don't put a lot of faith in the "2" pin relocate requirement. There is only one hole in the bolster and axle.
