Joyce, My understanding is that on the 'B' series tractors, once you lower the deck, the deck rolls along on the ground on it's own wheels and a blower mounted directly to the deck is supported directly by those deck wheels. On the 'BX' series, the mower deck is suspended beneath the body of the tractor, with the deck wheels not rolling on the ground, but only serving to help prevent scalping. A blower mounted to the deck would then tend to weigh that side down and cause an uneven cut. My dealer did not fully understand this until after my unit arrived, much to my chagrin.
As to installing and removing the rear-mounted blower assembly, it would be mind-bogglingly useful to have a step-by-step description of the procedure. I'm just not entirely sure what should be done first, how to I relieve the weight on the pins so that I don't need a sledge hammer and a metal rod to drive out the upper hitch pin for instance, and do I really need to loosen up all of the turnbuckles to get the arms to come off the sides? What step is first, second how do you support the assembly, where do you push and pull, what tools are useful, etc.?
If you, or anyone else, work out a procedure, or have any suggestions to offer before tomorrow when I plan go into battle once again with the blower assembly, please pass them on, and if I learn anything useful in the conflict, I will pass it on as well. If I survive.
Thanks.
