Tonight's episode of "Gold Rush" titled "Dozer Wars" was haunted by breakdowns and disappointments. The four crews are hoping their last-ditch efforts will pay off.
At Quartz Creek, the Hoffman crew is finally up and running. The brand new bigger motor is humming and after two hours, Todd stops the high-powered trammel to see what treasures it has uncovered; if any. Sure enough, big nuggets are being found, not just gold dust.
At Indian River, Dave's team has been keeping the two teams alive with their find. They have already uncovered $172,000 worth of gold. Now they are having a problem with their bulldozer. Their staff mechanic has a full-time job just maintaining the equipment. The equipment breaks down faster than he can fix it.
At Porcupine Creek, Fred gets a strange dozer bucket called the bedrock shark, and it works just fine for a short time, then one big rock does it in.
At the Big Nugget Mine, Parker has only gotten 80 ounces of his 300 quota. Now they have to build a hole from the overburden, or top soil that lies over the bedrock. Glenn comes to see Parker after checking on the overburden soil to find that there is gold being discarded. He feels that Parker is too inexperienced to know all the facts and only wants to go for the a fortune, rather than work his way to it.
At Quartz Creek, they stockpiled 17,000 yards of dirt while waiting for the trammel to arrive. Now they are shoving it in the giant trammel so quickly, they are running out of dirt. Now they need another place to dig to keep feeding the trammel. Ray, the designer of the big trammel suggests that they dig a previous dig from the turn of the century to find what was left behind from that prior dig.
The bulldozers are both laying dormant at both Hoffman mines. A bolt from the D-9 arrives and Mitch tries to get it going, but the other parts are weeks away.
A local mechanic comes to Porcupine Creek to evaluate the damage to Fred's machine. Thanks to Fred's ingenuity, he decides to use old scrap metal to form a piece that will replace the broken brackets.
At Indian River, they finally get the D-9 dozer working. Both teams are in dire need of the dozer, but Todd pulls rank on Dave and will take the D-9. The next morning, Dave awakens early to hijack the dozer before Todd shows up. Maybe he will get some needed landfill for their trammel while he waits for Todd. When Todd shows up, Dave keeps working while Todd just steams.
Dakota Fred's linkage works fine for two hours and now the idler wheel pin came out again. Dustin told Fred to order the part in the first place. The part costs $1,000, and Fred does a good job of jerry-rigging his equipment; until now.
At Quartz Creek, the D-10 dozer is finally back in business. Andy is working all night and day to clear the cut for Todd.
At Big Nugget, Parker's crew has convinced him to mine the overburden. Now they got gold to prove there really is gold worth mining.
Todd calls in Henry to dig holes from him and check to see if the land was mined before. Unfortunately, it was not virgin ground. Todd takes the blame for the failure and admits fault in this part of the "Gold Rush."
