Exploded Diagram

If you’re going to reno a Scott Bonnar or Rover cylinder mower, do yourself a favour and refer to the exploded diagram–you won’t regret it. This diagram features a Rover Scott Bonnar twin rail, which is nearly identical to a Scott Bonnar twin rail and will get you most of the way there for a Scott Bonnar solid deck mower.

The diagrams additionally reference many part numbers, which in turn describe details like bolt size and thread details. Print it double-sided and keep it in the shed when it comes time for reassembly, very handy to have nearby!

Budgeting Spreadsheet

How much does it cost to rebuild a Scott Bonnar cylinder mower? How long is a piece of string! The variables are countless and the answer will depend on your unique requirements, your desire to reuse/repair/replace specific parts and your budget. Do you just want a mower with a sharp blade that cuts grass or are you breathing new life into a tired machine with the intention of keeping it running in original or enhanced condition for another 40 years?

This spreadsheet (it’s really just a cost list–no functions!) breaks down most (not all) of the parts you may need or want to address as part of your project. Delete the rows or zero the dollar amounts where applicable, change other prices as required and then sum it all up. Then decide whether to include your labour cost and whether to tell your partner what you’ve got in mind!
