The Troy-Bilt Pony Lawn Tractor has a 42-inch mowing deck, which is good for cutting an average-sized lawn. Like all Troy-Bilt riding mowers and lawn tractors, the engines rely on oil to keep moving parts lubricated, maintain operating temperatures and remove debris. Before you buy oil for your Pony, you need to understand the engine's oil capacity as well as oil type and maintenance for best operating practices.
The Troy-Bilt Pony's oil capacity is based on the engine model, which is the Briggs and Stratton 17.5 Horsepower Intek engine. That engine model has a 44-ounce oil capacity. If your Intek model has an oil filter on it, the capacity increases to 48 ounces.
For best operation practices, the oil type used is specific to the ambient temperature when using your Pony. For 50 to 104 degrees Fahrenheit, SAE 30 is recommended. Use 10W-30 for -4 to 100 degrees, and 5W 30 for 32 degrees and below. You can use synthetic 5W-30 for all operating temperatures.
Prior to Service
You should check the oil levels after every 10 hours of use, or before using the Pony mower. Check the oil by locating the oil fill cap on the right side of the engine. Pull out the dip stick and wipe the end on a paper towel or napkin and ensure it's completely dry. Carefully replace the dip stick without allowing it to touch any of the oil fill hole's edges, and then remove it again. You should see the oil level as indicated by oil on the dipstick. If it is at the "full" line, no more oil is needed. Otherwise, add oil as necessary. If the oil mark is halfway between the dipstick end and the "full" line, fill with approximately 24 ounces.
You should change the Troy-Bilt Pony's oil every 50 mower hours. Old oil can retain sediment and debris instead of pushing it through the oil filter, thus increasing the friction in your engine parts instead of removing it or keeping parts cool.
Change the oil by removing the oil fill cap and removing the dipstick. Then loosen the drain port located below the oil's dipstick. Allow the oil to flow into a gallon-sized bucket. When the oil is done draining, replace the drain plug, tighten, and re-fill with fresh oil.
