Overview
This skid steer trencher attachment steps up from the 1 5/8" pitch Bigfoot to a 2" pitch chain, and that heavier chain is what lets it reach 12" cutting widths and a 4-foot dig depth. It suits skid steers and excavators up to 4.5 tonnes on 16–30 GPM. The wider chain also changes what the machine is for: at 10" and 12" you are trenching for pipe and utilities rather than cable.
Key Features of the Bigfoot Trencher Skid Steer Attachment
- Cutting depth: Up to 36"
- Cutting widths: 6"/ 8" /10" / 12"
- Recommended flow: 16 - 30 GPM
- Foot depth presets: 18" /24" / 30" / 36"
- Motor type: 2K Bell EATON
- 2" pitch chain rather than 1 5/8" — the heavier chain is what supports 12" widths and 4-foot depth.
- Choice of 3-foot or 4-foot dig depth, which is a different chain and frame rather than an adjustment.
- Cutting widths from 6" to 12" — utility and pipe trenching rather than cable.
- Fits skid steers and excavators up to 4.5 tonnes, so one attachment covers two machine types.
- HeadStart crumber system and adjustable foot depth control included.
Why This Bigfoot Trencher Earns Its Keep
- Depth and width are chosen at purchase, not adjusted on site — worth matching to the work you actually do rather than the deepest job you can imagine.
- A 12" trench moves four times the spoil of a 6" one, so wider is not free even when the machine can drive it.
- The excavator mount option opens ground a loader cannot reach — over banks, along ditches, and in confined access.

Choosing Your Bigfoot Trencher Chain and Cutting Width
The Bigfoot Trencher takes three decisions: chain type, cutting width, and on some models dig depth. Chain type is the one that most affects how the machine behaves in your ground.
| Chain type | Teeth | Best suited to |
|---|---|---|
| Earth Chain | Earth teeth on every second station | Soil, loam and light clay — the lowest-cost chain and the fastest in clean ground |
| Combo Chain | 70% Diggatac carbide teeth, 30% earth teeth | Mixed ground where you hit stone or hardpan intermittently — the general-purpose choice |
| Diggatac Chain | 100% Diggatac carbide teeth | Consistently hard, stony or frozen ground where an earth tooth would be destroyed |

Which Machines Fit the Bigfoot Trencher?
| Fitment factor | Requirement |
|---|---|
| Machine | Skid steer loaders and excavators up to 4.5 tonnes |
| Auxiliary hydraulic flow | 16–30 GPM |
| Chain pitch | 2" |
| Dig depth options | 3 foot or 4 foot |
| Cutting widths | 6", 8", 10" or 12" |
| Mount | Purchased separately — skid steer slide mount or excavator hitch |
| Included | Hoses, quick disconnects and crumber bar |
The Bigfoot Trencher uses a standard skid steer quick attach interface, so the common loaders all take it:
Bobcat
Caterpillar
John Deere
Case
New Holland
Takeuchi
Kubota
Gehl
Note your machine make and model at checkout and we confirm the Bigfoot Trencher mount and flow suit it before the order ships.
What to Order Alongside the Bigfoot Trencher
- A mount to suit your machine — the Bigfoot Trencher ships without one, and skid steer slide mounts and excavator hitches are separate items.
- Spare teeth — Diggatac and cup teeth are consumables and are cheaper to keep on the truck than to chase mid-job.
- A spare chain if you run mixed ground — swapping a chain is faster than changing every tooth on it.
- A nose roller kit and drive sprocket, which wear alongside the chain rather than independently of it.
Bigfoot Trencher Skid Steer Attachment Questions, Answered
Earth, Combo or Diggatac chain on the 2" pitch Bigfoot?
All three are offered on the 2" pitch Bigfoot in 6" to 12" widths. Earth chain carries earth teeth on every second station and is the fastest and cheapest in clean soil. Combo runs 70% Diggatac carbide with 30% earth teeth, which suits most contractors because it survives the stone you did not know was there. Diggatac is 100% carbide, for consistently hard, stony or frozen ground. Choosing Earth for rocky ground is a false economy; choosing Diggatac for clean soil costs more and cuts slower.
What is the crumber and why does it matter?
The crumber bar runs behind the chain and pulls loose spoil out of the trench floor. Without one you are left with a bed of loose material in the bottom of the trench, which has to be cleaned out by hand before pipe or cable can be laid to grade. Digga includes the crumber bar on the package.
3 foot or 4 foot dig depth?
It is a different machine rather than a setting, so choose by the work. Most utility and irrigation work sits inside 3 feet; 4 feet is for frost depth, deeper services and drainage falls. Buying the deeper machine for occasional use costs you weight and flow on every other job.
Can I run this on an excavator?
Yes — Digga rates it for skid steers and excavators up to 4.5 tonnes, and offers excavator hitches for Bobcat Xchange, John Deere, Kubota and Tag/Wain Roy couplers. The mount is a separate item.
What is the difference from the 1 5/8" pitch Bigfoot?
Chain pitch, and everything that follows from it. The 2" pitch chain carries wider cutting widths — up to 12" against 8" — and supports the 4-foot depth option. It also needs more flow: 16–30 GPM against 13–25.
What hydraulic flow does it need?
This one is rated for 16 - 30 GPM. Check that figure against your machine’s auxiliary hydraulic output before choosing — a machine that cannot supply the rated flow will never reach the rated performance, and one that exceeds the limit will run the attachment hot.
Will this fit my machine?
Check three things: it is built for Skid steer loaders and excavators up to 4.5 tonnes; the interface is Purchased separately — skid steer slide mount or excavator hitch; and it needs 16 - 30 GPM. Add your machine make and model at checkout and we confirm the fit before the order ships.
How is shipping calculated?
Shipping is calculated at checkout — add the item to your cart, enter your delivery address, and the shipping charge is shown before you complete your order. Lift gate service is available for residential deliveries and can be selected at checkout.
How do I order?
Add the item to your cart and check out online — the order page asks for your machine make and model, so there is no need to call ahead. We check the mount against your machine after the order and come back to you if anything needs changing. If you would rather ask first, email support@eskidsteer.com or use the chat button on your screen.
Contractors reach the Bigfoot Trencher searching for a trencher attachment, a skid steer trencher, or a excavator trencher for a machine they already run. It comes up alongside trencher chain and digga trencher when the job is cable, irrigation or drainage rather than post holes. All of it is genuine skid steer attachments equipment made in Dyersville, Iowa.
If you are choosing between this and the 1 5/8" pitch Bigfoot, the question is width rather than depth. Both reach 36". Only this one reaches 10" and 12" cutting width, and that is the difference between trenching for cable and trenching for pipe.
