The invention discloses a mower wheel structure which comprises a tyre, a wheel axle, a first bearing, a second bearing, a locking nut and an iron axle sleeve, wherein a bearing step in a tyre inner hole; the first bearing and the second bearing are arranged on two sides of the bearing step in the tyre inner hole; the iron axle sleeve is arranged between outer rings of the first bearing and the second bearing; the wheel axle sequentially penetrates through the first bearing, the iron shaft sleeve and the second bearing; the axle shoulder of the wheel axle is clamped at the outer end of the first bearing; the locking nut capable of being screwed towards the inner side along a second step is arranged on the second step; the iron axle sleeve is equal to or longer than the bearing step. According to the scheme, when a wheel is locked in the wheel axle, the iron axle sleeve instead of the wheel bears the axial force brought by the locking nut, so that the wheel can operate stably, the situation that the distance between the bearings is not changed is ensured, the axial size stability of the wheel is ensured, the hidden danger that the wheel shifts in the axial direction when a metal bearing is clamped in a plastic wheel bearing step to narrow the axial width is eliminated, the reliability is improved, and the service life is prolonged.
