As winter ends and temperatures rise, exhausted drivers struggle to stay awake on the graveyard shift. Eldon has an accident, and the forest turns into a nightmare when the soft ground and sinkholes attempt to swallow the massive skidder and delimber.

Winter is go time for the Pelletiers. Crews are pushing hard but three drivers suffer accidents and a busted pipe stinks up Telos camp. Business in the trailer shop is picking up so Allen thinks he needs a raise, but Jeff doesn't agree.

It's the big winter push and the Pelletiers have to double production to stay afloat. Tensions run high as Eldon threatens to fire Bonecrusher. Then, the family pulls together as their restaurant opens for business.

A wicked snowstorm hits Millinocket and catches the Pelletiers off guard. Massive equipment breakdowns cause tempers to flare and Eldon lashes out at Jeff for his lack of preparation. Then, Lester Dube recalls his father's frigid brush with death.

Rudy Pelletier and his crews race to make up for lost time but just wind up falling further behind. Rudy assigns his son Jason the dangerous, critical job of replacing a crippled bridge that was washed out in floods. Then two drivers crash their monster log hauling trucks sending shock waves through the Pelletier family that is fighting to keep their timber business alive.

The winter freeze hits Millinocket and it's finally time to hammer down. But a rookie driver can't handle the roads, rolls his rig twice and costs the Pelletiers. Then it's all hands on deck to battle through the first blizzard of the year.

The mills turn back timber and the Pelletiers struggle to make a profit. A stand of massive pine trees forces the company to harvest the old fashioned way, and the pressure of running both shops pushes Jeff to the edge.

The Golden Road dishes out serious punches and sends truck after truck into the shop. Lester and Bone Crusher get trapped when an angry land owner decides to shut down the road. And Randy wants to haul wood again after his near fatal accident.

The Pelletiers move an army of men and machines to their winter harvesting site. Rookie Aaron transports half million dollar machines across rough terrain, two heavy duty off road rigs are added to the fleet and tempers flare between Jeff and Bonecrusher.

The wet fall season has crippled production at Pelletier Inc. Just when things can't seem to get worse, a crane operator's rig falls through a dilapidated bridge. Back to back mistakes threaten a rookie's job, and a veteran hauler flirts with death.

Peak logging season brings anticipation of the deep freeze. They get their wish and then some, as brutal cold causes both equipment and emotional breakdowns. Nonstop hauling and disgruntled employees set some on a collision course during 'The Big Push'.

Winter is ending and it's all hands on deck. Rudy goes on a business venture, leaving Wayne in charge of operations. Larry makes a mess with a loading crane, Danny nearly destroys a bridge, and a young driver returns but his inexperience ends in disaster.
