I assume they did, but never saw one. The D9 (4 foot) uses 120 knives. The D95 (also shown for Cub) uses 152 knives, which would be the right number for an extra foot long. It also gives 2 different part nubers for the support roller on the D9 and D95. The problem with this theory is that the parts manual says that both support rollers are 4 feet. So you figure it out :lol:
