When you find yourself on top of the tractor, you will begin a new mini game in which you must kill all of the zombies in the field using the tractor. Accelerate the tractor using the R2 or RT buttons, brake and reverse the tractor with the L2 or LT buttons, and aim it using the left stick, as if you were controlling Juliet. You can mow down all of the grass in the field (and note that you will get an Achievement or a Trophy for doing so) but in addition to that you can also run over the zombies scattered about the field. You will have to kill one hundred zombies in total in this section, so maneuver the tractor around and run over as many as you can in as short a time as you can. Note that if you are going for the achievement in which you cut all of the grass in the field, you cannot get it if you run down all of the zombies first, as the scene will end and move on to the next section of the game at that point. You will have to endure a lot of repetitive dialogue from Nick as you drive the harvester around, but it'll be worth the lovely 15G and/or Bronze Trophy in the end.
After running over all of the zombies, you will immediately transition to waking up from the floor. A tractor will be roaring down the alleyway in front of you in an attempt at running you over. You will have to shoot the tractor several times with your Chainsaw Blaster before it reaches and crushes you to get out of this situation alive. If you need to, refill your Chainsaw Blaster ammo from the power-up to your left before shooting down the tractor.
After the tractor has been dispatched, run into the clearing ahead. A group of zombies will attack from directly ahead, but you can kill them all easily by shooting the rock to the upper right with your Chainsaw Blaster, sending it falling down on top of them. When all of the enemies are flattened, proceed ahead towards the narrow alleyway running between the two barns. Another small group of zombies will rush you from the tiny alleyway, four enemies in total. Chop through them with your chainsaw, and then proceed down the alley. Jump over the sandbags at the end of the alley and you will find yourself in the next area of the farm.
Zombies will spawn from your left and right. Grab the lollipop from the left and kill the one zombie that spawns from the ground nearby, and then look to the right to encounter a group of three flying zombies. Shoot them out of the sky with your Chainsaw Blaster, and then approach the fence by the floating arrow. Use your chainsaw to saw a hole through the fence, and mash the Square or the X button repeatedly to kick the fence in. Run through the hole in the fence and use the shop ahead if necessary. Otherwise, or when you are done with your shopping, head past the shop and up the hill. This path will lead you to another arena. To your left you will find zombies penned in by a fence, who will make great and easy pickings for your Chainsaw Blaster. You can also carve through the fence with your chainsaw and take them down with melee attacks in case you are running low on Chainsaw Blaster ammo.
When you are finished with the zombies, a headless body will appear for you to plop Nick's disembodied head down on. Don't head over to it just yet, though, for as you may have noted in your earlier battle with the zombies, there are plenty of coins waiting to be collected on the ridge above the barns to the left side of the arena. Head past the headless body and turn to the left, into the narrow alley going between the two barns. You will receive a tutorial prompt as you enter the alley describing how to use the Trampoline power ups. Simply hit the correct buttons when prompted in the right amount of time to ace the trampoline. Mount the trampoline ahead, and mash the buttons when they appear onscreen. Juliet will bounce off of the heads of numerous zombies, each of which will spew coins from its dead body. If you ace each button press, you will be able to milk plenty of coins out of the dead zombies and you will eventually end up on a wooden balcony that overlooks the farm. This balcony will have three sections, each of which will be overflowing with coins. Grab up all of the coins from the first section of the balcony, and then proceed straight and jump down to collect the coins resting on the walkway. Follow the walkway all the way to the other side of the arena, where you will find yet another balcony overflowing with coins. Grab up each of them and then drop back down to ground level. If you managed to pull of the trampoline correctly, you will have just collected an absolutely massive amount of coins.
Run back through the alley and plop Nick's head down on the headless body. As usual, you will have to complete a quick time event as Nick approaches the obstruction in the path, in this case a giant boulder in your way. You will end up on top of another wooden balcony, this time protecting Rosalind and her bus from the intruding zombies, who will be armed with explosives and coming in from the left side of the screen. Use your Chainsaw Blaster to blow up the enemies as they advance, and be sure to keep your ammo stocked via the power up on the balcony. Keep your eyes trained on the left side of the road, as this is where all of the enemies will come from. No need to scan other parts of the street below. Sometimes, a few of the zombies will sprint out of the holes from which they have just spawned. Be sure to take out the runners first, as they pose the greatest threat to Rosalind's bus. When the sequence is over, Juliet will jump down onto the bus. As you look up, you will see zombies trying to push a boulder down on you. Shoot their tractors before they can reach the boulder and Rosalind will speed her bus through the next area, sending Juliet falling down off of the bus and a giant boulder rolling down the hill ahead, making for yet another blocked path. Turn down the road to the right, and prepare for still more of the O'Bannon Farm.
