Mower Height Lever Set-Screw Grip
Replacement grip for a push-mower or zero-turn height-adjust lever whose plastic knob has cracked off. It is 90 x 36 x 18 mm and has a 24 x 7.5 mm slot, 50 mm deep, that takes any flat bar up to 24 x 7 mm or round rod up to 7 mm. Two M4 set screws in brass heat-set inserts (5.5 mm bores) clamp it to the bar, so you don't need the exact OEM size.
3 in Mower Deck Anti-Scalp Roller
This replaces the plastic anti-scalp roller on a mower deck: a crowned roller 76 mm (3 in) across and 38 mm wide with a 10.0 mm plain bore that turns on a standard 3/8 in (9.5 mm) shoulder bolt. The hub stands 2 mm proud of the rim on one side so the rim never rubs the deck bracket. Six ribs and drain holes keep it light at about 60 cm³, so grass clippings and water don't pack inside. Before you order, measure your old roller's diameter, width and bolt size.
