Frequently Asked Questions

What engine does the LS MT125H use?

The LS MT125H runs a Yanmar 3TNV80F 3-cylinder, indirect injection, water-cooled Tier 4 diesel engine producing 24.7 gross horsepower and 17.2 PTO horsepower at 3,000 RPM. With a displacement of 77.32 cubic inches (1,267cc) and a bore and stroke of 80mm x 84mm, this is the same proven Yanmar engine family found across premium sub-compact tractors worldwide — giving LS MT125H owners confidence in long-term reliability, parts availability, and service familiarity no matter where they are in Colorado or beyond.

What is the PTO horsepower of the LS MT125H?

The LS MT125H delivers 17.2 PTO horsepower to your implements. What makes this machine stand out in the sub-compact class is the dual PTO configuration — a standard rear PTO at 540 RPM for traditional 3-point implements like tillers, box blades, and rear mowers, plus a standard mid-PTO at 2,500 RPM for a 60-inch mid-mount mower deck or 50-inch front-mount snow blower. The PTO select lever gives you independent control of the rear PTO, mid-PTO, or both simultaneously — a level of versatility that sets this machine apart from competitors in its price range.

What is the hitch lift capacity of the LS MT125H?

The LS MT125H Category I 3-point hitch lifts 992 lbs at the hitch end and 728 lbs measured at 24 inches behind the lift point. The position control system provides smooth, repeatable hydraulic lift performance across all compatible implements. For Colorado property owners connecting rear blades, tillers, landscape rakes, and box blades, the hitch is designed for fast, intuitive hookup with an ergonomically positioned control lever that is easily accessible from the operator’s seat.

What type of transmission does the LS MT125H have?

The LS MT125H features a dual-pedal 2-Range Hydrostatic Transmission (HST) — one of the most operator-friendly transmission configurations available on any sub-compact tractor. There is no clutch to manage and no gear-shift learning curve. Simply press the forward or reverse pedal to move, and release it to stop. Low range delivers 0 to 5.9 km/h (0 to 3.67 mph) for precise implement work and tight maneuvering. High range opens up to 14.0 km/h (8.70 mph) for efficient property travel. Cruise control is standard — set your speed and maintain it hands-free during long mowing passes or repetitive loader cycles. For first-time tractor owners in Colorado, this transmission is the fastest path from beginner to confident operator.

How wide is the LS MT125H?

The LS MT125H measures just 47 inches wide with standard tires — making it one of the most maneuverable sub-compact tractors in its class. It threads through standard residential gates, navigates narrow barn aisles, and works in greenhouse and outbuilding environments that larger compact tractors simply cannot access. The standard foldable ROPS drops down for storage in low-clearance buildings and older outbuildings common on Colorado hobby farm properties. At 97 inches long and with a minimum turning radius of just 7.87 feet, the MT125H handles tight spaces with confidence that larger machines cannot match.

What are the fluid capacities for the LS MT125H?

Knowing your fluid capacities before every service keeps your MT125H running at peak performance. Here are the complete specifications straight from the operator’s manual:

Engine Oil: 2.9 liters (0.8 US gallons) — API CF-4 or CI-4, viscosity per ambient temperature chart

Fuel Tank: 25 liters (6.6 US gallons) — Ultra Low Sulfur Diesel (ULSD), below 15 ppm, ASTM D975 No. 2

Engine Coolant: 3.3 liters (0.9 US gallons) — 50% soft water / 50% anti-freeze (ASTM D6210)

Transmission Oil (standard): 11.5 liters (3.0 US gallons) — API GL4 ISO VG 32/46

Transmission Oil (with loader installed): 13.0 liters (3.4 US gallons)

Transmission Oil (with loader and backhoe installed): 17.7 liters (4.7 US gallons)

Front Axle Oil: 2.0 liters (0.5 US gallons) — API GL4 SAE 80W90

Grease: NLGI Grade 2 multi-purpose — all grease fittings, front axle holder, 3-point linkage

Always check and top off transmission oil after installing a loader or backhoe for the first time, as hydraulic lines need to fill before the gauge reads accurately.

What is the maintenance schedule for the LS MT125H?

Staying on top of your maintenance schedule is the single most important thing you can do to protect your investment. The LS MT125H operator’s manual outlines the following service intervals:

Daily: Check engine oil, fuel, coolant, transmission oil, battery, tire pressure, lights, indicators, bolts and nuts, brake and HST pedal operation, and radiator screen

First 50 Hours: Replace engine oil and filter, replace hydraulic oil filter, check all fluid levels, adjust brakes and belts, tighten cooling hose connections, tighten safety frame and wheel bolts — contact Legacy Tractors for your first 50-hour service

Every 50 Hours: Lubricate all grease fittings, clean radiator screen, check transmission oil, check front axle oil, inspect hydraulic hoses, check battery

Every 250 Hours: Replace engine oil and filter, replace hydraulic oil filter, replace HST filter, adjust fan belt tension (target 10–14mm deflection at 22 lbs pressure), drain fuel tank

Every 500 Hours: Change front axle oil, change transmission oil, replace fuel filter cartridge

Every 1,000 Hours: Adjust engine valve clearance (target 0.15 to 0.25mm) — dealer service recommended

Every 1,500 Hours: Inspect, clean, and test fuel injection nozzle — dealer service required

Every 2,000 Hours or 2 Years: Replace engine coolant, inspect and replace fuel hoses and coolant hoses as needed

Also check and retorque wheel bolts at 5 hours, 50 hours, and every 300 hours thereafter. Front wheel torque is 64–69 N.m (47–51 lb.ft) and rear wheel torque is 69–78 N.m (51–58 lb.ft).

What is the Yanmar engine warranty on the LS MT125H?

The Yanmar 3TNV80F engine in the LS MT125H is backed by a Yanmar emission control system warranty of 3,000 hours or 5 years, whichever comes first, for variable speed engines in the 19 to 37 kW range. This warranty covers the fuel injection system, air induction system, electronic controls, EGR system, exhaust after-treatment components, hoses, belts, connectors, and all emission-related assemblies. Important note: LS Tractor USA warranty terms prevail over Yanmar warranty terms where applicable. For warranty service and questions, contact Legacy Tractors in Fort Collins or reach Yanmar directly at 1-800-872-2867 or CS_support@yanmar.com.

Can the LS MT125H use biodiesel fuel?

Yes. The LS MT125H Yanmar engine is approved for biodiesel concentrations up to B20. Blends of B7 or lower (7% biodiesel, 93% petroleum diesel) require no special preparations and standard service intervals apply. For blends above B7 up to B20, the engine requires halved service intervals for engine oil, oil filter, fuel filter, and water separator changes, plus daily monitoring of engine oil level for dilution. Biodiesel blends above B20 are not approved. Raw pressed vegetable oils are never acceptable as fuel in any concentration. Always purchase biodiesel from BQ-9000 accredited producers and certified distributors in North America, meeting ASTM D6751 standards.

What is the total weight of the LS MT125H?

The LS MT125H weighs 1,444 lbs (655 kg) without ballast, with a factory weight distribution of 40% on the front axle and 60% on the rear axle. The total maximum permissible operating mass — including ballast, operator, and all mounted equipment — is 2,601 lbs (1,180 kg). The maximum permissible front axle load is 1,433 lbs and the maximum rear axle load is 1,631 lbs. Optional front ballast weights (4 x 44 lbs plus a 22 lb bracket) help counterbalance heavy rear implements and improve front-end stability during loader work — particularly important on Colorado’s sloped terrain and when operating with the 3-point hitch loaded.

What implements can the LS MT125H run?

The LS MT125H is one of the most versatile machines in the sub-compact class when matched to the right implement package. Approved implements and their maximum recommended specifications per the operator’s manual include:

Mid-Mount Mower: 60 inches (1,524mm) maximum cutting width

Rear Mounted Mower: 60 inches (1,524mm) maximum cutting width
