I now have one of these Mower attachments, and, thanks to Will Haggle, now have a parts list and instructions, until I read this manual I thought all these Merry Tiller Mowers were the same, But Not So! Mine has three alloy front rollers, the one in the manual shows hardwood rollers, the most important difference is that the cutter cylinder on mine is driven from the Vplex pulley, but the one in the manual is driven from the axle drive without the need for a vplex pulley, I can see how they did it, by locking the two drive sprockets together, but was this the first type or the later type? my Merry tiller leaflets all show the Mower driven from the vplex pulley, they are also fabricated differently, but which one came first?
