Work on Rail-Mower Mower Deck

Today I took the cap off the gearbox on the Bolens 18048 mower deck that will be used with the rail-mower and I poured in 11 oz. of Hypoid 85W90 gear oil, GL-4 spec, per the 18048 manual, which calls for 11 oz. of SAE 90 oil.  In the afternoon I removed the height adjustment mechanism since it will not be needed in the deck's new function and would be an obstruction to getting the deck underneath the motorcar trailer.  I removed the rear roller for the same reason.  They will serve as spares for the other 18048 mower deck I will be using with the Bolens 1455 garden tractor.  I also have two additional mower gearboxes for these decks, so if I blow up any of them I will have an immediate replacement.
