Attachments for a Case CX57C
A Case CX57C is a 12,456 lb (5.65 t) mini excavator, which puts it in the 4–6 t mini class. It takes 45 mm bucket pins on a pin-on stick. 12 attachments in the Quarrymark range fit a Case CX57C: 3 digging buckets, 2 ditching buckets, 2 hydraulic hammers, 2 rakes and 1 post driver hammer, plus 1 thumb and 1 trenching bucket. 6 of those are a direct fit: right weight class, right pin diameter. Prices start at $1,195.20.

Operating weight is from the manufacturer’s published spec sheet. Pin diameter and coupler style are derived from that weight against our own tonnage bands. They are the right starting point for a machine in this class, not a statement about your specific unit. Verify both against your OEM spec, or send us a photo of the stick end and we will confirm it before you order.

We grade the fit rather than answer yes or no. Direct fit means the weight class and the mounting both check out. Fits your class means the attachment is rated for a machine of this weight and mounts pin-on. Verify first means something, usually the pin diameter, needs confirming before it ships. Telling a contractor a bucket fits when it does not is how you earn a freight claim.

Buying attachments for a Case CX57C
What size bucket fits a Case CX57C?
Buckets from 12" up to 60" wide are rated for a Case CX57C. The widths we stock in this class are 12", 24", 30", 42", 60". On a 5.65 t machine the narrow end of that range is the trenching and utility-line width, and the widest sizes are for grading and cleanup, where you are moving loose material rather than breaking ground. Go wider than the machine's rated capacity and you will feel it as lost breakout force and a tippy load at full reach, not as a fitment problem.
What pin size does a Case CX57C use?
A Case CX57C in the 5.65 t class typically runs 45 mm bucket pins on a pin-on connection. That is the number to check first, because it is the one that stops a bucket going on: the weight class tells you whether the machine can lift the attachment, the pin diameter tells you whether it will physically pin up. 4 of the 12 attachments listed here are the right weight class but drilled for a different pin. They are flagged "check pin size", and a bushing kit or a quick coupler resolves them. Pin diameter is derived from the machine's operating weight against our own tonnage bands, so measure yours or send us a photo of the stick end before ordering.
Can I run a hydraulic hammer on a Case CX57C?
Yes. 3 of our hammers are rated for a machine this size. They run 500–1,356 joules of impact energy, which is the range a 5.65 t carrier can actually feed. The constraint is hydraulic, not structural: the machine needs an auxiliary circuit with the flow and relief pressure the hammer is specified for, and a machine plumbed only for a thumb will not run a breaker without the second circuit. Check your auxiliary flow on the machine's spec plate, or send it to us and we will match the hammer to it.
Will a quick coupler fit a Case CX57C?
We do not currently list a coupler rated for a 5.65 t machine in this catalog. Tell us the machine's stick-end pin centres and we will source one. Call (704) 555-0140.
