Thanks Deejay,
Will add a picture of sprockets when mower is re-assembled hopefully soon. Thanks to those who noticed the small crack in the rail. Have attached attached a pic of the fix. Would also like any ideas on a ball bearing front roller for the mowers. This is the one thing that lets down the mowers a little. Have looked at installing a conveyor roller? Would appreciate any suggestions as I think I have seen at least one on the site before. [Linked Image]
