How to Grease the Wheel Bearings on a Zero Turn Rider

Your zero turn rider is designed for heavy duty cutting tasks. The hard work your mower is exposed to requires regular maintenance to ensure a long and reliable service life. Part of this maintenance includes greasing the wheel bearings on the front of your mower. This maintenance is easy to forget but it’s important. You should lubricate the bearings one to two times each mowing season to protect them from wear and keep them spinning smoothly.  Here’s how to grease the wheel bearings on your zero turn rider.

You’ll need a grease gun and grease for your zero turn mower.

Before performing any maintenance on your lawn mower, refer to your owner’s manual for maintenance instructions and safety information.

Park your lawn mower on a level surface, stop the engine, and remove the ignition key. Move to the front of your mower and locate the grease fittings on the outside hub of the caster wheels. These fittings, also referred to as zerks, make it easy to apply grease to the wheels internal bearings.

Start by cleaning the fitting on the wheels with a rag. Remove any grass, dirt or debris that could interfere with greasing the wheel bearings. Make sure the spring-loaded bearing ball inside the inlet is visible and free to move.

Attach the nozzle on the end of the grease gun to the fitting on one of the caster wheels. Pump grease into the fitting until you see a little bit of grease ooze out of the wheel bearing. Use your rag to wipe away excess grease that oozes out to prevent the accumulation of dirt and debris. Move to the other front wheel and grease the wheel bearing. When complete, again wipe excess grease with a rag.

You may never think about it, but the caster wheels in the front of your zero turn riders undergo a real workout, which means they need to undergo maintenance as well. Don’t forget to factor your wheel bearings into your lawn mower maintenance checklist. No matter how small it may seem, performing maintenance on your wheel bearings plays a huge role in the performance of your equipment.
