MT3 Series Compact
The MT3 is LS Tractor's upper-range compact series, spanning 35–57 gross horsepower across 22 model configurations. Powered by LS's own L3C19-T CRDI turbocharged engine, the MT3 competes directly with the Kubota L and M-Series and John Deere 3 and 4 Series at a substantial price advantage. With three transmission options — HST, Synchro Shuttle, and the signature Powerclutch — the MT3 is the most configurable compact tractor in its class.
LS L3C19-T CRDI Turbocharged Engine
The MT3 runs LS's own L3C19-T engine — a 3-cylinder, 114.7 cu in (1.879L), direct-injection (CRDI) turbocharged diesel meeting Tier 4 Final without a diesel particulate filter. This is an LS-designed engine, not a third-party sourced unit, built to CRDI standards that reduce noise, vibration, and fuel consumption compared to older indirect-injection designs. The engine powers the full 35–57 HP range depending on calibration.
- •LS L3C19-T: 3-cylinder CRDI turbocharged diesel, 114.7 cu in
- •Tier 4 Final compliant — no diesel particulate filter required
- •CRDI direct injection: lower fuel consumption and emissions vs IDI
- •2,600 RPM rated speed — broad torque curve for loader and implement work
- •Preheat starting aid standard for reliable cold-weather starting
Three Transmission Choices — HST, Synchro, or Powerclutch
No other compact tractor series in this HP class offers three distinct transmission options on the same platform. The MT3 comes in HST (H), Synchro Shuttle (E), and Powerclutch (PCT/PCTC) variants. The Powerclutch is LS's electro-hydraulic clutch integrated into the Synchro Shuttle gearbox — it lets you change gears without fully depressing the clutch pedal, combining the smoothness of a power-shift with the efficiency of a mechanical transmission.
- •HST (H variants): 3-range hydrostatic, stepless speed control
- •Synchro Shuttle (E variants): mechanical, gear-driven efficiency
- •Powerclutch (PCT/PCTC): F16×R16 with electro-hydraulic clutch assist
- •Powerclutch enables gear changes without full clutch engagement
- •Side-mounted main gear lever maximizes cab space and egress
Category II Hitch and High-Capacity Hydraulics
From the MT342 upward, the MT3 uses a Category II 3-point hitch with 2,755 lb lift capacity — the same hitch class as the John Deere 4 Series compact utility tractors. The hydraulic system delivers 12.3 GPM total flow (8.2 GPM implement + 4.1 GPM steering). Two sets of front and rear remote valves with detent are standard, covering all standard implement requirements without paying for options.
- •Cat II 3-point hitch: 2,755 lb lift capacity (MT342–MT357)
- •Total hydraulic flow: 12.3 GPM (8.2 implement + 4.1 steering)
- •2 pairs front remote + 2 pairs rear remote valves, detent, standard
- •Loader LL4106/LL4001: 2,633 lb lift capacity
- •Extendable lower links for easier implement hook-up
Wide HP Range with ROPS and Cab Options
The MT3 covers the most horsepower options of any LS Tractor series — nine distinct HP/transmission combinations from 35 HP to 57 HP — giving buyers the ability to match precisely to their implement requirements. ROPS and factory-cab versions are available at every HP level. The cab models (HC/PCTC/C) include A/C, heat, and a flat rubber-mat platform. The MT357 and MT352 cab variants include an optional Bluetooth radio.
- •35 HP to 57 HP across the lineup — nine distinct power levels
- •ROPS and factory cab (A/C + heat) available at every HP level
- •MT357PCTC: 57 HP Powerclutch cab — top-of-range configuration
- •PTO HP: 28 HP (MT335H) to 48.4 HP (MT357PCT/PCTC) — all independent
- •Foldable ROPS on open-cab models for low-clearance storage
