Mower deck F1145 deck belt

Hi



I need to fit a new deck belt to a F1145 60" deck



It has a driveshaft to the gearbox on the deck



can I slide the inner shaft out of the driveshaft to remove the deck from the tractor or will this cause problems with re-assembly ?



The problem I have is getting the belt round the gearbox pulley, I think I have to remove the gearbox to get the belt round this pulley



does anyone know an easy way to do this or is it just a matter of removing the blades and lifting the gearbox ?





thanks in advance



Paul
