Zero Turn Lawn Mower Wheel | 13-650-500" Tyre Size | 170mm Hub Width (SP13X650-500)

Fitment should be confirmed by measuring the wheel currently fitted to your mower rather than relying on the mower make or model alone. For the SP13X650-500, compare the 330mm wheel diameter, 148mm tyre width, hub width and 1/2″ (12.7mm) axle diameter with your existing wheel.

Also check that there is sufficient clearance inside the castor fork for the wheel to rotate and swivel freely. The supplied axle bolt is 1/2″ x 240mm.

Measure the wheel already fitted to the mower and compare the overall wheel diameter, tyre width, hub or boss width, axle diameter and mounting hardware. You should also check the available space between the castor fork arms.

Matching only the 13 x 6.50-6 tyre size does not guarantee fitment because hub widths and axle diameters can vary between wheel assemblies.

A smooth tread is well suited to a zero-turn mower front castor because the wheel needs to swivel frequently as the mower changes direction. With no aggressive tread blocks gripping into the lawn, the castor can pivot with less tendency to dig into or scuff the turf during tight turns.

The front castor also does not require the traction-focused tread pattern used on a mower’s driven wheels.

The semi-pneumatic rubber construction provides some cushioning over grass and minor surface irregularities without relying on conventional tyre pressure. This means there is no need for inflation or regular pressure checks.

For a mower front castor, this gives a practical combination of cushioning, straightforward maintenance and a smooth tread suited to frequent direction changes.

The SP13X650-500 has a maximum load capacity of 200kg per wheel and a maximum operating speed of 20km/h. These are operating limits and do not determine fitment, so the wheel dimensions, axle size and castor fork clearance still need to be checked separately.
