Case-IH MX 120 specs: hp, weight, years

Name: Case-IH MX 120
Brand: Case-IH

CDC 6T-590 six-cylinder or CUMMINS CDC 6T-590 diesel. The brochure said 118.4 horsepower. OECD strapped one to a dynamometer and got 109.6 at the power take-off — and that is the number to size an implement from. Compared at the engine's rated speed, where the brochure figure is quoted, the shaft gave 106.2 hp — 10.3% below the claim.

The claimed engine power (gross or net not stated) of the Case-IH MX 120 is 88.3 kW (118.4 hp); that is a claim for the engine, not a measurement at the PTO.
The Case-IH MX 120 is four-wheel drive (4WD).^{Source 1}
The Case-IH MX 120 has a CDC 6T-590 engine, a 6-cylinder 5.88 L unit.^{Source 1}
The Case-IH MX 120 weighs 6,265 kg (13,812 lb) unladen.
The Case-IH MX 120 has a rear PTO running at 540/1000 rpm.
The three-point hitch of the Case-IH MX 120 lifts 5,226 kg (11,521 lb) at the lower-link ends.
The hydraulic pump of the Case-IH MX 120 delivers 109 L/min (28.8 gpm).

How does the MX 120 compare with its class?

Worth knowing:
An unladen mass of 6,265 kg is high for its class — 20% above the median of 5,230 kg across the 284 machines within 10% of its power that hold this figure.

How much horsepower does an MX 120 have at the PTO?

At the PTO shaft an MX 120 has 109.6 hp (81.7 kW), measured on OECD Test 1678 — against 118.4 hp claimed for the engine. Between the flywheel and the PTO you lose the fan, the alternator, the hydraulic pump and the transmission — which is why the brochure figure is the wrong one to size an implement from.

Engine, claimed (gross/net not stated): 118.4 hp
PTO, measured: 109.6 hp
Drawbar, measured (unballasted): 95.6 hp

How much fuel does an MX 120 burn per hour?

Measured on OECD Test 1678 (tested as the MX 120 (4 WD)), at each condition the laboratory recorded.

Cost per hour = fuel used per hour × your fuel price (per litre, or per US gallon for the gal/h figure).
