McCormick CT36 and related tractors: S4L2, loaders and hitch controls

CT36 output comes from the longer-stroke engine

The CT-series brochure rates CT36 at a higher engine speed than CT28 and identifies a larger-displacement four-cylinder Mitsubishi. The operator manual's specification table names S4L2 for the larger engine and S4L for the smaller one. They share bore size, but the stroke differs.

The extra character in the engine designation is useful parts information, not decorative branding.

Mitsubishi's August 2004 engine manual makes another distinction: its SL2 compression-pressure standard and lower limit are higher than those for SL. Both are specified at the same test cranking speed. A workshop evaluating a CT36 should first confirm the fitted S4L2 and then use that engine's limits.

Mixing a CT28 compression threshold with CT36 running-power figures produces an inconsistent assessment.

Loader, backhoe and mower packages have dependencies

McCormick pairs the L105 loader with CT28 and CT36 in the attachment table. The MH76 backhoe listing expressly requires installation of that loader. A used backhoe's model number alone therefore does not establish that an otherwise bare CT36 has the complete specified installation.

Check the loader and mounting equipment with the backhoe.

The brochure distinguishes loader capacity at full height from capacity at a lower specified height and from breakout force. Those describe different jobs. A large breakout-force number cannot stand in for the mass the loader can place on a high trailer.

Match the load position before using the table to plan a lift.

The MS66 mower is another separate package, listed with a mid-PTO drive and a floating caster-wheel arrangement. A rear PTO connection does not establish that a used CT36 has the mid-drive equipment needed by that mower. Inspect the drive and mounting pieces together instead of treating every PTO-driven attachment as equivalent.

A slow-descending hitch is not necessarily a weak pump

The operator manual describes a lowering-speed knob that restricts implement descent. Closing it can hold the implement even when the position lever is moved down. Its setting therefore matters when investigating a hitch that raises normally but will not lower.

That control changes descent, not the engine's available power.

The hydraulic drawings separate the mechanical tractor from HST equipment. The HST drawing adds its own unit, filter and cooler alongside the implement and steering circuits. A filter or hose diagnosis needs the matching diagram.

Before working beneath an implement, lower and secure it; a hydraulic control setting is not a physical support.
