Hi Melb,
Firstly a big warm welcome to the ODK Forum.
Before we go any further could you please be so kind as to take a whole heap of photos both close ups and general of the mower and its components not forgetting to remove the chain case and take some close ups of all the sprockets for assessment.
Just to give you a heads up, if you want to sandblast the chassis then you will have to remove every last nut and bolt. At first it might be rather daunting but we can help ease that anxiety for you here and make the task much easier.
Looking forward to those photos.
Cheers,
BB
