LS MT357PCTC

Frequently Asked Questions

Does the LS MT357PCTC have enough horsepower for a 10-foot rotary cutter at elevation?

The LS MT357PCTC delivers 57 gross horsepower and 48.4 PTO horsepower — enough to run a 10-foot rotary cutter under most conditions at Northern Colorado elevations. Most commercial 10-foot rotary cutters require 40 to 55 PTO HP under heavy cutting conditions; the MT357PCTC’s 48.4 PTO HP sits within that range and provides more headroom than the 45.6 PTO HP produced by the MT357HC in gear mode. At Fort Collins elevation (approximately 5,000 feet), turbocharged CRDI engines maintain power better than naturally aspirated engines because the turbo partially compensates for thinner air — but operators running full-width rotary cutters in dense or wet grass on uphill passes should select a lower range gear to keep engine RPM near 2,600 for maximum PTO output.

What is the LS MT357PCTC Powerclutch transmission and how does it work?

The LS MT357PCTC Powerclutch Synchro Shuttle transmission uses a wet multi-disc clutch pack to handle forward/reverse direction changes without the operator touching the clutch pedal — making loader cycles, grading passes, and repeated repositioning significantly less fatiguing than a traditional dry-clutch machine. The MT357PCTC offers 16 forward and 16 reverse gear combinations across its range and main gear selections, giving the operator precise ground speed control at a fixed engine RPM for PTO-dependent work. Operators set a range and main gear for a task, set throttle for 540 PTO RPM, and then use only the shuttle lever for direction changes — the Powerclutch system engages directional changes smoothly without clutch slip or pedal depression. The manual does note that the clutch pack engagement should complete within six seconds — prolonged partial engagement generates heat and wear, a point that Legacy Tractor Sales & Service covers during every MT357PCTC delivery orientation.

How often does the LS MT357PCTC DPF regen, and can it regen while working?

The LS MT357PCTC is designed to perform a passive DPF regen approximately every 50 hours under normal working loads — this is the documented factory interval for this 57HP Tier 4 CRDI machine. Owners across multiple forums report that heavy-load work (tilling, plowing, working the tractor at sustained high RPM under full load) keeps exhaust temperatures high enough to burn off soot passively, achieving close to the 50-hour interval. Lighter-duty work at high RPM but low load — idling, road travel, or running implements that don’t tax the engine — can cause soot accumulation faster, triggering regen cycles more frequently, sometimes in the 12–25 hour range. The MT357PCTC can continue working during a passive regen cycle, which typically runs 18–25 minutes. Keeping the air filter clean — particularly during Fort Collins cottonwood season — and using quality ULSD diesel from a high-turnover station are the two most consistently cited factors in maintaining normal regen intervals; Legacy Tractor Sales & Service addresses both during delivery and at every service appointment.

Is the EGR valve on the LS MT357PCTC a known issue?

The EGR (exhaust gas recirculation) system on the LS MT357 57HP platform has generated documented forum discussion, with some 2021 and 2024 model-year owners reporting EGR fault codes and valve replacements under warranty. LS issued an updated EGR valve for the MT357 under warranty — meaning owners who experienced the issue received the replacement part at no cost through their authorized dealer. The MT357PCTC’s 6-year limited powertrain warranty and 2-year bumper-to-bumper warranty cover EGR components, and all emissions-related components carry a federally mandated 5-year emissions warranty on top of the LS factory coverage. Legacy Tractor Sales & Service’s service department has access to LS factory technical support and current OEM part revisions — including any updated components — so MT357PCTC owners in Fort Collins and Northern Colorado are covered without needing to locate out-of-state service.

What is the LS MT357PCTC hitch lift capacity and what implements will it handle?

The LS MT357PCTC 3-point Category 2 hitch lifts 2,755 lbs at the hitch ends and 2,469 lbs measured at 24 inches — putting it well above what most 50–60 HP class competitors offer at the three-point. This capacity makes the MT357PCTC capable of handling heavy rear implements including large rotary tillers, rear blades, box scrapers, landscape rakes, and Category 2 finish mowers without approaching the hitch limit under normal operating conditions. The extendable lower links on the MT357PCTC allow the operator to connect a wider range of Category 2 implements independently without requiring a second person for hookup. Position and draft control comes standard on the MT357PCTC — the operator can set precise implement depth for consistency across an entire field pass without manually resetting the hitch.

How does the LS MT357PCTC cold start in a Colorado winter?

The LS MT357PCTC includes a standard glow plug preheat system that is the first and most important step for cold-weather starting — the operator’s manual and experienced MT357PCTC owners both recommend cycling the preheat two to three complete cycles before cranking when ambient temperatures are below 20°F. At Fort Collins elevations and during January cold snaps when overnight temperatures drop below 10°F, a magnetic oil-pan block heater is a practical addition that owners in the LS Tractor owners community consistently recommend for reliable single-crank cold starts. Winter diesel treatment is essential for Northern Colorado MT357PCTC operators — ULSD diesel can begin to gel at temperatures below 10°F without additive treatment, restricting the fuel filter and causing hard starts or no-starts that are not mechanical failures. Legacy Tractor Sales & Service stocks cold-weather diesel additives and can advise on the correct treatment rate for expected overnight lows at your specific elevation.

Should I choose the LS MT357PCTC or the LS MT357HC for my property?

The LS MT357PCTC and the LS MT357HC are both 57-gross-horsepower factory-cab tractors on the same frame with the same engine, loader lift capacity (2,396 lbs), and hitch lift capacity (2,755 lbs) — but the right choice depends entirely on how the operator plans to use the machine. The MT357PCTC’s 16-forward Powerclutch Synchro Shuttle transmission is the better fit for operators who run a wide range of implements requiring precise PTO RPM control, frequent direction reversals under load, and the ability to fine-tune ground speed across 16 gear combinations. The MT357HC’s hydrostatic (HST) transmission is the better fit for operators who prioritize single-pedal infinite speed control — especially for mowing, tight-space loader work, and operators who want the simplest possible operation. The MT357HC cab model produces 15.0 GPM of total hydraulic flow vs. 12.3 GPM on the MT357PCTC, which matters for high-demand hydraulic implements. Legacy Tractor Sales & Service has both transmission configurations available and encourages every buyer to discuss specific implement plans before choosing.

What are the loader lift specs on the LS MT357PCTC with the standard loader?

The LS MT357PCTC’s standard front-end loader lifts 2,396 lbs — confirmed by LS Tractor USA. The loader reaches a maximum lift height of 94.4 inches, providing clearance for filling standard dump truck beds and high-sided trailers. The fender-mounted joystick controls the loader from a natural hand position that reduces operator fatigue during extended loading sessions. Two pairs of front remote valves come standard on the MT357PCTC, enabling hydraulic grapples, pallet fork positioners, and other hydraulically actuated front attachments without added cost. At 2,396 lbs of lift capacity, the MT357PCTC is capable of moving loaded pallet forks, large round bale spears, and filled material buckets with consistent reserve — buyers who regularly handle loads approaching the upper limit should discuss ballasting options with Legacy Tractor Sales & Service to ensure front axle weight and stability.

Does the LS MT357PCTC warranty cover transmission and emissions components?

The LS MT357PCTC carries a 6-year limited powertrain warranty covering the engine, transmission (including the Powerclutch wet-disc clutch system), and drivetrain components — plus a 2-year bumper-to-bumper warranty covering the full tractor including electrical, hydraulics, PTO, and 3-point hitch components. All emissions-related components on the MT357PCTC — including DPF, EGR, and associated sensors — carry a federally mandated minimum 5-year emissions warranty, which runs concurrently with the LS factory coverage. The LS powertrain warranty includes parts and labor with no deductible at authorized dealers. Legacy Tractor Sales & Service performs all warranty repairs on the MT357PCTC as an authorized LS dealer in Fort Collins — Northern Colorado owners do not need to transport a warranty-claim machine out of the region for covered repairs.

What does the LS MT357PCTC weigh and why does it matter for loader work?

The LS MT357PCTC cab model weighs 4,380 lbs without ballast — making it one of the heavier machines in the sub-60 HP compact utility class, and heavier than the MT357HC cab at 4,446 lbs is the HST version by a small margin. Tractor weight directly determines rear-axle ballast available when the front-end loader is under load — a heavier base machine keeps the rear wheels planted when lifting near the loader’s 2,396 lb capacity. At 4,380 lbs, the MT357PCTC’s factory cab adds meaningful ballast compared to an open-ROPS configuration (3,869 lbs), which directly improves loader stability. Operators handling consistently heavy front loads on the MT357PCTC may still benefit from adding rear wheel ballast or a rear implement for counterweight — Legacy Tractor Sales & Service can spec the right ballasting configuration for your typical load profile.

How often does the LS MT357PCTC need air filter service?

The LS MT357PCTC’s air filter should be inspected at every 50 hours under standard operating conditions — but Fort Collins and Northern Colorado operators face conditions that require more frequent checks. During cottonwood season (late May through June), cottonwood seed fibers accumulate on the MT357PCTC’s primary air filter element significantly faster than normal dust, and a partially restricted air filter reduces combustion efficiency, increases soot production, and can trigger DPF regen cycles earlier than the normal 50-hour interval. Legacy Tractor Sales & Service recommends visually inspecting the MT357PCTC’s air filter element every 8–10 hours during cottonwood season — the one-piece tilt hood on the MT357PCTC provides fast, easy access for this check without tools. Dusty summer conditions along unpaved driveways and pasture roads in Larimer, Weld, and Boulder counties similarly demand more frequent air filter attention than the standard service schedule assumes.
