Keep your John Deere mower deck from scalping the lawn with these replacement gauge wheel sets from Caltric.
This is a 3-pack, meaning you get three complete wheel and axle assemblies.
They’re designed to fit a ton of John Deere models, especially the ZTrak series like the Z920M, Z930M, Z950M, and the Z900 series, plus some Quik-Trak stand-on mowers and even the TerrainCut front mowers.

Basically, if your mower takes parts TCU27151, TCU34060, or TCU27152, these are for you.

Each wheel is 5.5 inches in diameter, with a steel axle and a plastic wheel.

They’re black, so they blend in.
The whole assembly is about 6.6 inches long and weighs around 5 pounds for the set.

They mount on the deck to support it and keep it at the right height, which stops those annoying bare spots when the deck digs in on uneven ground.
They’re made in China and come with a 3-month warranty.

Installation is straightforward—just bolt them on where your old worn-out ones came off.
If your deck wheels are wobbly or the bearings are shot, swap in these new ones for a smoother cut.
