We are due to pick a very second hand one up tomorrow or later in the week. Depending on what vans are available we might need to remove the deck... any one fancy telling me how?
As above, split pins here and there. Ours is a c600 - on that there's a lever under the footplate on one side to release the drive belt tension too. If the belt's still tight you'll struggle to get the deck off.
Also worth noting (and that manual doesn't seem to mention it) that there should be a tiny lever on the rear of the tractor, where the sweeper joins the tractor, which shuts off the hydrostatic gearbox - without flicking that lever, you won't be able to push it.
