Thanks Deejay
I actually rang Keith from Turf Machinery Services and had a chat about the rear rollers. He said Scott Bonnar did bring the 20" out with the twin piece roller. Which I was happy to hear. The thing with my 20" is that it's a bit of a bitza. It has no model number plate. So a bit hard to know its birth date.
But i'm always interested in where I can get spare parts. I'm guessing a rear roller set would be quite costly.
I might have to get the the crack V cut and mig welded.
I'll check my PM's mate. Thanks for the time to check it out.
