40-Inch vs. 48-Inch Tow-Behind Aerators: 4 Checks Before Ordering

Verify your gate width, hitch plate, and ballast blocks before checkout.

01
Check Your Backyard Gate Opening First
A 40" aerator fits through a standard 48" walk gate (~43" total axle width); a 48" aerator requires a 52"+ double gate.
02
Verify a 1/2-Inch Pin Hitch Plate on Your Mower
All four Agri-Fab and Brinly units use a universal clevis hitch that drops a 1/2" steel pin through your tractor's rear hitch hole.
03
Strap Down Two or Three Concrete Cinder Blocks
Use a nylon ratchet strap through the block cores so ballast doesn't bounce on uneven ground.
04
Raise Transport Wheels Before Crossing Concrete
Always pull the transport lever up before driving across driveways, sidewalks, or Shallow sprinkler heads.

Questions

Why aren't my tow-behind aerator spoons pulling full 2.5-inch plugs?

Check two things: soil moisture and tray weight. Without at least 70–120 lbs of concrete blocks on the tray AND moist soil (watered the day prior), curved coring spoons will merely dimple hard turf.

What is the difference between enclosed tube tines and open-backed coring spoons?

Tow-behind homeowner aerators use curved open-backed coring spoons ('knives') because they roll continuously and self-release soil plugs without jamming as the drum turns.
