What It Is

This is a 4-pack of aftermarket anti-scalp rollers designed to replace OEM part numbers 1-603299, 116-9981, 68-2730, 103-3168, 103-4051, 103-7263, 103-7363, and 109-2098. They prevent the mower deck from digging into turf during sharp turns or on uneven ground—critical for zero-turn mowers on lawns with dips or slopes.

Fitment & Compatibility

Check your OEM part number against the list above. These fit many Exmark models: Explorer, Lazer Z, Turf Ranger, Turf Tracer, Pioneer, Radius, and Quest. Measure your existing roller—these are typically 3.25" outer diameter with a 0.5" inner bore and a 2.5" wide roller body. Verify deck size (48"-72" decks use these, but some smaller decks may require different rollers). If your mower uses a different bolt pattern or shaft diameter, these won’t work.

Key Things to Know

• Quality vs OEM: Users report these are slightly less durable than genuine Exmark rollers but cost 60% less. Expect 1-2 seasons of residential use.
• Installation: Simple bolt-on job—remove the cotter pin or retaining clip, slide off old roller, slide on new one, and re-secure. No special tools needed.
• Common gotcha: The included bushings may be a loose fit; check that the roller spins freely after mounting. If it binds, the deck will scalp anyway.
• Pack size: You get four, which is exactly what most zero-turn decks need (two front, two rear). No spares.

Should You Buy It

Buy this if you have an Exmark with a 48"-72" deck, the OEM part numbers match, and you want a budget-friendly replacement for worn rollers. Skip it if you need heavy-duty commercial durability or your mower uses a non-standard roller size.
