How Your Machine Is Delivered
Mini excavators, mini skid steers, and other machines move by LTL / flatbed freight carrier because of their size and weight. Here is what to expect:
- Curbside delivery with a liftgate lowers your machine safely to ground level at your address.
- The carrier calls ahead to schedule a delivery appointment — you will not be caught off guard.
- Someone 18 or older must be present to sign for the shipment.
- Please have a firm, reasonably level spot with clear truck access for the unload.
Attachments & Smaller Items
Buckets, augers, and other attachments or small parts may ship separately via standard ground rather than freight, and can arrive on a different day than your machine.
Inspect Before You Sign
Always inspect your delivery before signing. Walk around the machine and check for any freight damage while the driver is still there.
If you see anything, note it on the delivery receipt / Bill of Lading (BOL), take clear photos, and report it to us within 48 hours. Documenting damage at delivery protects your claim and lets us make it right quickly.
Alaska, Hawaii & Remote Locations
Shipments to Alaska and Hawaii, as well as remote or limited-access sites, are arranged on a per-order basis — please contact us for a freight quote before ordering. We cannot ship machines to PO boxes.

Powerful and dependableNeeded something for trenching for water lines, so I took the plunge. Power is impressive for the size. The Yanmar engine starts right up cold and never bogs down, even when trenching for water lines. Perfect size for a cattle ranch. Trailers easily behind my pickup and I can move it between sites myself. Fuel burn is low for the amount of work it does. Solid company, solid machine.
Derek G. (verified owner) –
Works as describedGood machine for the price. Shipping was a touch slow but the equipment is solid. Shipping was free and the freight driver called ahead to set up delivery. I’d buy from them again without hesitation.

Solid with a few quibblesOverall I’m happy with it. Took a little setup out of the gate but runs great now. Fit and finish is better than the photos show.
James Bennett (verified owner) –
Just what the job neededI was nervous ordering equipment online, but I’m so glad I did. Operators at a county road crew all comment on how responsive it is. No lag in the controls at all. Tracks grip well on the slope behind our place. I’ve had it on wet ground septic work with no trouble. The cab is comfortable for long days. Heater works great for winter septic work. Showed up on a flatbed in about ten days, well strapped and undamaged. I’d buy from them again without hesitation. Five stars, easy.

Exactly what I neededFinally replaced our tired old machine. Honestly thought it might be underpowered at this price but it handled cleaning out ditches like a much bigger machine. Maintenance is straightforward, grease points are easy to reach, and the manual actually makes sense. Tracks grip well on the slope behind our place. I’ve had it on wet ground cleaning out ditches with no trouble. The price-to-power ratio is hard to beat right now. If you’re considering it, do it.

Solid little workhorseFinally replaced our tired old machine. Perfect size for a remodeling business. Trailers easily behind my pickup and I can move it between sites myself. Coming from renting, owning this paid for itself in about two months of septic work. The cab is comfortable for long days. Heater works great for winter septic work. Arrived faster than I expected with all the paperwork included. I’d buy from them again without hesitation. Will be ordering parts and attachments from them again.

Worth every pennyI was nervous ordering equipment online, but I’m so glad I did. Three months in here in Ohio and it’s been flawless. Cold mornings, mud, long hours — it just works. We added it to weekend property projects and it’s already the most-used machine on the lot. Freight was free to my door and the driver was patient getting it off the truck. Quiet enough that I can run it early without waking the house. Five stars, easy.

Paid for itself fastShopped around for weeks before pulling the trigger. The cab is comfortable for long days. Heater works great for winter trenching for water lines. Perfect size for a small excavating outfit. Trailers easily behind my pickup and I can move it between sites myself. Three months in here in Florida and it’s been flawless. Cold mornings, mud, long hours — it just works. Arrived faster than I expected with all the paperwork included. Would absolutely buy again.
Joel S. (verified owner) –
Pretty good buyRuns strong. Took a day to dial in the tracks but it’s been great since. It handles digging a pond better than machines twice the price.

Just what the job neededFinally replaced our tired old machine. The cab is comfortable for long days. Heater works great for winter snow and debris cleanup.

Exceeded my expectationsShopped around for weeks before pulling the trigger. Customer support answered my questions before I bought and again after delivery. That sealed it for me. The thumb is a game changer for picking up rock and brush while cleaning out ditches. Delivery took just under two weeks and the forklift unloading made it painless. The price-to-power ratio is hard to beat right now. Two thumbs up from me.
Dustin W. (verified owner) –
Punches above its weightI was setting fence posts all last weekend and it didn’t miss a beat. For the money there’s nothing else close. Dig depth and breakout force are better than I expected. setting fence posts that used to take all day now takes a couple hours. The 3.8-ton class is the sweet spot for us — tight enough to fit through a gate but it still has the muscle for setting fence posts. Delivery took just under two weeks and the forklift unloading made it painless. Plenty of power left in reserve when setting fence posts. Five stars, easy.

Exactly what I neededFirst excavator I’ve ever owned. We added it to a sod farm and it’s already the most-used machine on the lot. Dig depth and breakout force are better than I expected. digging irrigation lines that used to take all day now takes a couple hours. Power is impressive for the size. The Yanmar engine starts right up cold and never bogs down, even when digging irrigation lines. Shipping was free and the freight driver called ahead to set up delivery. The price-to-power ratio is hard to beat right now. Telling everyone at the co-op about it.
