Lawn mower height adjuster lever
Push mowers set cutting height with a plastic lever that engages notched positions, and the pawl tooth wears until the wheel drops mid-mow. A replacement lever is roughly 110 mm long and 15 mm wide with an 8 mm pivot hole, a tooth that indexes into 6 mm notches, a spring pocket and a wide thumb pad. Print it flat at 100 percent infill in PETG or ASA to survive sun, vibration and grass juice, and fillet the tooth root so it does not snap again.
Mower brands use different pivot sizes and notch spacing, so SpeakCAD generates the lever from the dimensions you take off the old one rather than hoping a generic part fits. Tweak the tooth depth in chat if it does not engage cleanly. The preview is free in your browser.
Design a lawn mower height adjuster lever 110 mm long, 15 mm wide, 8 mm thick with an 8.2 mm pivot hole, a 4 mm wide indexing tooth 5 mm tall 30 mm from the pivot, a 6 mm spring pocket, and a 25 x 20 mm textured thumb pad.
