OutdoorKing Repair Forum Forums Restoring, Customising and Modifying Reel-Type Mowers New/Old Bonnar 45

Do these pictures help to identify the mower? The cogs and chain look to be in good condition. The reel adjusters need to be tapped with a hammer lightly to take up the slack when adjuster nut is backed off and the screw is wound to move reel closer to the bed knife. The mower worked well on mowing the yard, however I have a Buffalo lawn. I was advised by a local mower shop that the 45 would be perfect for my Buffalo grass. I have since found that i need to raise the cutting height above the standard SB 45 to maintain healthy grass. an increase of 10 to 20 mm is required. I can increase the length of the slotted adjuster or increase the diameter of the front roller to eek out some height. any other suggestions?
Thank you.
