How to remove rear wheel from Gravely ZT 34

I have a Gravely ZT 34 whose left rear tire is flat. I need to remove the wheel so that I can get the tire repaired, but I can’t figure out how to do it. There’s a bolt head on the end of the apparent axel but not sure which way to turn it. I tried both directions, but it moves slowly with very stiff resistance either way and does not appear to loosen. The inner side has no obvious way to help.

Re: How to remove rear wheel from Gravely ZT 34

For the left wheel side, to loosen the bolt you turn the wrench or ratchet towards the front of mower.

Bolt might be designed as a tight tolerance piece and harder to remove(like a nylock nut) to not loosen up unexpectedly, so it might require some extra force, but it's also possible that factory could of used some blue or purple Loctite, which you'll want to get to spread a bit on the bolt when you replace it after getting tire fixed.

On the right side to loosen, you turn wrench/ratchet towards the rear of mower.

The wheel slides off a shaft, but be careful as you remove to not lose the keyway(a piece of metal that slides into slots of both the wheel shaft and wheel hub to help keep them locked together. The keyway is what actually helps make the mower move when hydro(s) are engaged, while the bolt/washer is only on there to keep wheel assembly from sliding off the wheel's drive shaft.

The keyway is a softer piece of metal that's made to shear(break) away and wheel will have no engagement to move itself, if something goes bad with the wheel system to not tear up the hydro(s). It's a replaceable part.
