BarneyC 2 #1 Posted January 18 Hi All, I am a new member but hope my content is of interest and may inspire others to use their Suffolk punch mowers. I am a fan among other things of Suffolk punch mowers with Suffolk iron foundry engine. I have attached a picture, both of these 75cc mowers are in use, the 14" mower will be refurbished sometime over the next couple of years, the 12" mower has been re-purposed so it has a new life as a scarifier which is what I would like to talk about in a few forthcoming posts. The 75cc iron engine on the 12" has also been slightly modified using my lathe and milling machine, more to follow... 2 pmackellow and nigel reacted to this Share this post Link to post Share on other sites
BarneyC 2 #2 Posted Sunday at 07:58 PM A few years ago I converted the 12" Suffolk Colt to scarifier / lawn rake duties. All the conversion work is reversible. I bought a 12" scarifier cassette of the Atco, Allett, Qualcast, Suffolk punch type. The blade was removed from the mower and the deflector from the cassette modified to fit the mower fixing at the top with the existing screws and underneath with bolts from either side threaded into captive nuts on a piece of angle. (A rod with tapped holes either end would be better as the angle collects swarf) When in use the chaff flies nicely into the grass box. The more interesting bit was fitting the scarifier blades. The 16mm shaft from the cassette was too short to be modified so I used a new piece of 16mm bright mild steel shaft and machined the ends to fit deep groove ball bearings either end, I think these were 6202 with external sleeves to match the mower. The right hand end of the shaft was machined to suit the existing chain sprocket. The chain sprocket is driven by the original drive pin and the cassette came with its own drive pins and belleville washers to hold it all compressed together. The picture shows the new drive shaft with centre hole in the end. The deflector lower bolt can also be seen and the some will recognise it as an M8 bolt head where 5/16" would serve equally well!!
