Designed primarily for homeowners and light-duty commercial use, this model stands out for its impressive balance between power and user-friendliness. Whether tackling tree trimming, firewood cutting, or general yard maintenance, the Poulan 178085 delivers reliable performance.

In terms of maintenance, the Poulan 178085 features an automatic oiling system that keeps the chain lubricated during cutting, ensuring a longer lifespan for both the chain and bar. This feature reduces the need for manual lubrication, making it more convenient for users.

In summary, the Poulan 178085 is a versatile and reliable chainsaw equipped with a powerful engine, a well-designed bar, and a range of safety features.
