We have a parts book for an FT510 but the mower details FT20?

 

They are the same model ( 20 stands for 20” & 510 stands for 510mm). It is the same for the FT610 & FT24

 

My machine has a 3 sectioned rear roller and either: the “outer's” don’t work or the shaft going through the middle is broken


The roller is in 4 sections and the middle part is 2 sections with a shaft coming out of each side. The “outer’s” contain sprung loaded plungers and they have probably stuck and require cleaning and regreasing.
