Hi Dazza, and a warm welcome to the forum. We all like to learn new things and tinker here. Please include in your next post any numbers you can find on the chassis, it should have a data plate or stamped serial number and perhaps a sub-model ID....also cutting width may help narrow it down.
Please do not PM me asking for support. Please post your questions in the appropriate forums, as the replies it may receive may help all members, not just the individual member. Kindest Regards, Darryl
