Excavator & Quarry Calculator
RustPotato's Rust Excavator & Quarry Calculator turns diesel into ore: what the Giant Excavator, quarries and pump jacks make and when they fill.
Every diesel machine, one barrel at a time

Rust diesel machines: excavator, quarries and pump jacks
The RustPotato Excavator & Quarry Calculator turns barrels of Diesel Fuel, the barrels players simply call diesel, into the ore each Rust monument machine makes. The Giant Excavator digs 2,000 sulfur ore from one barrel in 2 minutes; the Sulfur Quarry digs 1,000 in 2 minutes 5 seconds. The excavator pays twice as much per barrel, and the quarries fill their box much sooner. RustPotato reads every rate, slot count and tank size from the game files. Run and fill times assume nobody empties the box or refuels mid-run.
How the Giant Excavator in Rust turns diesel into ore
The Giant Excavator in Rust, at the Giant Excavator Pit, digs only while its diesel engine runs: one barrel goes in the moment the engine starts, then one every 2 minutes, whether or not the arm is digging. The arm only starts when an ore button is pressed with the engine already running, so start the engine first, then press the ore you want, and press it again after every restart.
- Fuel: a single slot of 20 barrels, 40 minutes of running; somebody has to refill it for a longer run
- Output: two piles of 36 slots each; anything that does not fit spills onto the ground beside them
- Supply drop: the computer by the pit charges one every 10 minutes of engine time, 5 barrels' worth, with no limit
The Metal button pays Metal Fragments, frags ready to use with no smelting; the HQM and Sulfur buttons pay ore that still goes in a furnace. Diesel Fuel cannot be crafted in Rust: its barrels are picked up off the ground, where they spawn among the barrels at some monuments, and a vending machine trades one barrel for 300 Low Grade Fuel (LGF), so at that price a barrel on the Sulfur button turns 300 Low Grade Fuel into 2,000 Sulfur Ore.
Ore still has to be smelted: see the Smelting Calculator.
Rust monument quarries: sulfur, stone and HQM
A Rust monument quarry burns a barrel every 2 minutes 5 seconds and works out its ore in small batches. Its output box has 18 slots and its fuel tank takes 120 barrels. One barrel gives 50 high quality metal ore at the HQM Quarry (box full after 36 barrels), 1,000 metal ore and 5,000 stones at the Stone Quarry (box full after 3 barrels) and 1,000 sulfur ore at the Sulfur Quarry (box full after 18 barrels).
Rust pump jacks and crude oil
A Rust monument pump jack, also written pumpjack, is a quarry that pumps liquids: one barrel lasts 2 minutes 5 seconds and brings up 60 crude oil and 170 low grade fuel. There is one at the Power Plant, the Train Yard and the Water Treatment Plant. Its box is full after 38.2 barrels' worth of pumping, and then it stops.
A worked run in Rust: 10 barrels of diesel
In Rust, 10 barrels in the Giant Excavator on Sulfur give 20,000 sulfur ore in 20 minutes, twice what the same barrels give in a Sulfur Quarry, 10,000 in 20 minutes 50 seconds. The two machines need different trips back: the excavator's fuel slot of 20 barrels runs out after 40 minutes, while a quarry stops as soon as its box fills, after 6 minutes 15 seconds of running at the Stone Quarry, 37 minutes 30 seconds at the Sulfur Quarry and 1 hour 15 minutes at the HQM Quarry.
| Machine | Output | Time |
|---|---|---|
| Giant Excavator, Sulfur | 20,000 sulfur ore | 20 min |
| Sulfur Quarry | 10,000 sulfur ore | 20 min 50 s |
| Pump jack | 600 crude oil and 1,700 low grade fuel | 20 min 50 s |
Questions about Rust diesel machines
How much HQM per diesel in Rust?
The Giant Excavator in Rust digs 100 High Quality Metal Ore per barrel of diesel on its HQM button, 3,000 an hour of running; the HQM Quarry digs 50 per barrel, 1,440 an hour. Both give ore, so add a furnace: a Large Furnace smelts 100 HQM ore in about 2 min 13 s. Set the Excavator & Quarry Calculator to Amount I need and it gives the barrels for the ore you want.
How much sulfur does the Giant Excavator make per diesel?
The Giant Excavator in Rust digs 2,000 Sulfur Ore from each barrel on its Sulfur button, 60,000 for an hour of engine time, shared between two output piles that fill after 36 barrels. A Sulfur Quarry digs half as much per barrel, 1,000, and 28,800 an hour. Run your barrels in the Excavator & Quarry Calculator to see when those piles fill.
How do you start the Giant Excavator in Rust?
The Giant Excavator in Rust needs diesel in its engine's fuel slot, 20 barrels at most: start the engine, then press the ore button, since a button pressed before the engine runs starts nothing, and keep the two output piles emptied. A full slot keeps the arm digging for 40 minutes before someone has to refill it.
How do you change what the Giant Excavator digs?
The Giant Excavator in Rust changes what it digs when you press another of its four buttons: HQM, Sulfur, Stone or Metal. It switches on its next tick, within 1 s. The part of a batch left over from the old button, less than two items, waits until that button is pressed again.
Why did my monument quarry stop?
A Rust monument quarry stops for one of two reasons: its fuel tank is empty, or its 18-slot box is full and the next batch is destroyed. Empty the box and switch it back on; on Stone, check it every 3 barrels, about 6 minutes 15 seconds of running. Under Quarries, the calculator says after how many barrels the box fills and what the engine still holds.
Is a pump jack worth the diesel in Rust?
A Rust monument pump jack is worth the diesel if you refine the crude: each barrel yields 60 Crude Oil plus 170 Low Grade Fuel, and a Small Oil Refinery turns each crude into 3 Low Grade Fuel, so one barrel ends as 350 Low Grade Fuel. Under Pump Jacks, the calculator adds the refined crude to the Low Grade Fuel total.
Why is RustPotato's Excavator & Quarry Calculator the best diesel calculator for Rust?
RustPotato's Excavator & Quarry Calculator is the best diesel calculator for Rust because RustPotato reads every rate, slot count and tank size from the game files. You can start from Barrels I have or Amount I need across the Giant Excavator, the monument quarries and the pump jacks, and see when the two piles or the 18-slot box fill.
