LS Tractor MT242H to XR4145 specifications

MT242H hitch measurements and older R-series differences

The MT242H's rear linkage has two published lift ratings. LS's MT2 operator manual gives 1,808 lbf at the lower-link ends and 1,433 lbf measured 24 inches behind the lift point. The smaller figure belongs to the longer load position.

Calling it the capacity at the ends understates one rating while concealing the measurement that an implement buyer needs. Keep both coordinates beside the weight.

That same manual separates the MT242's roll-bar and enclosed versions. Their unballasted weights differ, as do their fuel capacities. Loader and backhoe equipment add further weight; the tractor-only figure cannot describe the whole transported combination.

The MT242 specification also identifies a four-cylinder Yanmar, unlike the three-cylinder LS engines in the MT345E, MT350E and XR4145 records. Engine displacement alone will not select their service parts.

Choose the transmission before comparing PTO output

The original XR4100 brochure gives the XR4145 gear and hydrostatic versions the same gross engine output, but different PTO outputs. The synchronized shuttle supplies 16 forward and reverse choices; the hydrostatic version uses three ranges. Its higher total hydraulic flow does not mean a larger implement supply: the brochure shows the same main-pump flow and a larger steering contribution on the hydrostatic model.

Those are separate circuits in the comparison.

Check the equipment column as well. The brochure lists the mid PTO as optional. A rear PTO listing does not establish that a used XR4145 has the additional mid drive installed.

Nor should the XR4150's hitch category be transferred to the smaller XR4145 just because both appear in the XR4100 brochure.

The older R4041 and R4047 operator manual distinguishes their engine model codes and separates mechanical-clutch tractors from HST versions. Its hitch schedule also labels the lower-link and rearward measurement positions separately. Use that R-series schedule for those tractors; the newer MT2 lift numbers do not replace it.

The MT3E ordering choice differs again: LS's 2018 product guide lists an eight-speed shuttle arrangement alongside three-range hydrostatic alternatives. These are distinct driveline selections within this comparison, not successive settings on one tractor.
