From memory there were two types, one fitted on the side of the tractor and drove off the deck, but never saw one in the metal and have no idea how. The second and later type fitted to the rear and used the same mounting bar as the Powered Grass Collector and was driven by the PTO pulley under the seat.
Post a couple of images, rear of tractor and the shredder and it may help.

Just exchanged emails with a friend who used to work for Westwood and he confirms that the only chipper of that era was side mounted. A square section spigot bolted to the chassis and a mating one on the chipper which he says was a copy of an Alko one.
Those D1200s were prone to catching fire as a result of engine vibration damaging the fuel line and wiring loom. The engine is mounted on “rubber cotton reels” similar to exhaust mounts and these soften and allow excessive engine movement particularly as it hits the final compression when switched off. So may be as well to check the mounts and also ensure that you have some slack in the loom and fuel feed.
He says that a rear mounted chipper was not introduced until after the merger with Countax and was not available for the D1200.

On the subject of image size, correspondence on this forum would suggest that Shrinkpix is the way to go. No argument with that but if you are running Windows XP or 7 the reduction facility is there with a couple of clicks of the mouse – that’s all I use!

Westie welcome to the forum. That will be a good one to exhibit as I am sure very few people will have seen or even know such attachments were available for these ride on mowers. On the subject of photos, shrinkpic has the advantage it does everything automatically. Note the thumbnail that appears in the forum posting may well be cropped but the image will open to show the full picture.
