As rpm drops, the only way to maintain or increase horsepower is to provide additional torque. The output horsepower is greater than or equal to rated horsepower as the engine is pulled down to 1750 rpm.

The peak torque rise also occurs near the rated economy power take-off (EPTO) speed.

The PowrQuad™ transmission can be ordered on any of the 5ML Tractor models with three different options to meet producer needs: 16F/16R PowrQuad, 16F/16R PowrQuad with creeper, or 32F/16R Power 8. These three transmissions options come standard with a 540/540 Economy/1000 power take-off (PTO) and are compatible with the pressure-and-flow compensated (PFC) hydraulic system.

Pairing a PowrQuad  or a Power 8 transmission with PFC hydraulics provides more hydraulic flow, increased hitch lift capacity over PowrReverser models, and an electrohydraulic (EH) hitch control for repeatable hitch movements. 

The ergonomically placed transmission control allows the operator to change gears and ranging with one simple control. Two buttons, a rabbit or turtle indicator, allow one to gear up (rabbit) or gear down (turtle) within a range. A range change can be made with a simple press of the declutch button rather than using the foot clutch. If preferred, the foot clutch remains incorporated into the operator station for use.

Ranges on the transmission control can be selected by moving the controller in an H pattern. The lever selects ranges A, B, C, or D. Ranges C and D are fully synchronized. That means, when upshifting, operators can move from range C to D without stopping the tractor. On the downshift, operators can move from D all the way to B without stopping.

Maximum productivity is achieved with clutchless hydraulic shifting between forward and reverse and is ideal for loader work and any other applications that require frequent directional changes in tight spaces. An electrohydraulic fingertip directional lever control allows the operator to effortlessly switch directions with a small finger motion.

This control is located on the left side of the instrument console and selects forward, reverse, and neutral positions. It also allows the operator to steer and shift direction with the left hand, freeing the right hand to operate other tractor controls, such as the loader, rear implements, or hand throttle.

NOTE: A neutral start switch requires the directional lever be in the neutral position to start the engine.

PowrQuad transmissions include:

• Wet clutch
• Ergonomically mounted transmission lever controlling both gear and range changes
• Declutch button on the range lever
• Left-hand reverser
• Constant-mesh, helical-cut gears
• Pressure-lubricated top shaft
• Positive park pawl
• Three-speed PTO
• Neutral start switch

Reversible stub shaft

All 5ML Tractors equipped with a PowrQuad or Power 8 transmission  have a reversible stub shaft with six splines and 21 splines (38 mm [1.5 in.]). To switch between 540 and 1000 speeds, simply remove the snap ring, flip the PTO shaft, and reinstall the snap ring. The tractor PTO operates at 540-rpm speed when the six-spline end of the shaft is visible, and at 1000 speed when the 21-spline end of the shaft is visible.

The reversible 540/ 540E/1000 PTO stub shaft is located in a dry cavity to allow changing from 540/540E rpm to 1000 rpm or vice versa without any oil spillage. This interchangeability allows the matching of different implements. The reversible stub shaft improves uptime as no bolts are needed for removal, just a simple snap ring.

The PowrReverser transmission provides 16F/16R speeds. This transmission comes standard with a dual-speed 540/540 Economy power take-off (PTO) and is ideal for applications requiring frequent directional changes.

Hydraulic wet forward and reverse clutches maximize durability and outlast the life of any dry clutch. When tractors are run by multiple operators with a variety of experience levels, a wet clutch is the best way to maintain transmission integrity and performance while decreasing clutch replacement costs.

Two platform-mounted levers offer easy and comfortable shifting for a pleasant operator experience. The gear-shift lever is easy to reach and the less-used range lever is shorter. Unique knobs make it easy to distinguish between the two. Also incorporated into the gear shift lever is the declutch button. No foot clutching is required to shift between gears within a range.

NOTE: The PowrReverser transmission is not available for the 5125ML tractor.

Integrated declutch button on gear shifter

The forward lever, or gear shifter, selects one of four speeds, all which are synchronized shifts for on-the-go shifting with the use of the clutch or declutch button. The rear lever selects ranges A, B, C, or D. Ranges C and D are fully synchronized. That means, when upshifting, operators can move from range C to D without stopping the tractor. On the downshift, operators can move from D all the way to B without stopping.

Maximum productivity is achieved with clutchless hydraulic shifting between forward and reverse and is ideal for loader work and any other applications that require frequent directional changes in tight spaces. An electrohydraulic fingertip directional lever control allows the operator to effortlessly switch directions with a small finger motion.

This control is located on the left side of the instrument console and selects forward, reverse, and neutral positions. It also allows the operator to steer and shift direction with the left hand, freeing the right hand to operate other tractor controls, such as the loader, rear implements, or hand throttle. The PowrReverser transmission has a built-in engagement override valve for additional safety. This valve requires the clutch pedal to be depressed one time after each engine start before the transmission will begin to operate normally, giving the operator another opportunity to put all focus on the tractor.

NOTE: A neutral start switch requires the directional lever be in the neutral position to start the engine.

The speed of directional changes can be adjusted to the operator's preference or application demands with the field-installed infinitely variable control kit.

The 16F/16R transmission includes:

• Wet clutch
• Platform-mounted shift levers (four gears, four ranges)
• Declutch button on the gear lever
• Left-hand reverser
• Constant-mesh, helical-cut gears
• Pressure-lubricated top shaft
• Positive park pawl
• Neutral start switch

All tractors have economy PTO (E-PTO), a fuel saving feature that allows producers to operate rear implements at 540 PTO rpm but at lower engine rpm. The result is lower engine vibration, reduced noise, less wear and tear on the engine, reduced fuel consumption, and increased operator comfort.

NOTE: See PTO functional area for more information on E-PTO.

The standard OOS on 5ML Tractors was designed for low-clearance applications. It features a low-profile seat, a smaller-diameter steering wheel, protected controls, and a low-profile, rear-mounted rollover protective structure (ROPS). Combined with the sloping hood, this is beneficial to the operator’s visibility to the front of the tractor. Rounding off these standard features and incorporated into each operator platform is a shield which limits heat transfer from the hydraulics to the operator.

All of the most crucial operator controls are conveniently located within arms’ reach on the right-hand console control pod. The engine throttle control, selective control valve (SCV) levers, power take-off (PTO) engagement, and hitch-lift control levers are grouped together. On the 5ML, this control pod is positioned on the right-side fender, protected from low-hanging crops by a shield.

Right-hand fender shield and low profile seat

Color-coded bands on the SCV levers correspond with the color on the rear SCVs, making it easy for any operator to determine which lever operates which rear SCV.

The 5ML Tractor also offers optional fender extensions to minimize crop disturbance, especially in orchards or tree nut applications. Two fender extension options are available to meet varying tire sizes and coverage preferences.

The foldable ROPS on the 5ML Tractor has a unique design and is 15.2-cm (6-in.) lower at maximum height than the standard 5M Tractors.

The shifter linkages are tighter to offer a more accurate shift pattern, which translates to a crisper throw between gears. Incorporating technology found on standard 5M Tractors, the 5ML now offers a declutch button, enabling the operator to shift gears within a range without the use of the foot clutch.

Dash details:

• Cluster
• Controls
• Steering wheel

5ML Tractors also include the following features:

• Retractable seat belts
• Rear certified ROPS for OOS tractors
• Heat shield limiting hydraulic heat passed onto the operator
• Key-switch interlock prevents bypass starting
• Audible and visual PTO warning alerts when the operator leaves the seat with the PTO engaged
• Positive park position prevents the tractor from moving when the engine is off
• Four amber turn-signal/flashing warning lights for road transport (these are break-away)
• Slow-moving vehicle (SMV) sign alerts other road users during transport
• Safety decals keep safety in the minds of new and experienced operators
• Left- and right-hand steps provide easy and convenient access from both sides of the tractor
• Fuel system is fully grounded to meet safety and fuel fill regulation requirements
• For convenience of operation, the fuel and diesel exhaust fluid (DEF) fill are both on the same side with clearly marked and color coded caps. The DEF tank has a capacity of 12.1-L (3.2 gal.), which is more than enough to sustain proper tractor operation and fuel treatment for more than one full tank of diesel. A field-installed lockable fuel cap is offered for protection and peace of mind.

Transmission controls on PowrReverser™ transmission models:

Gear and range shift levers are located to the right of the operator. The gear lever incorporates a declutch button enabling the operator to shift gears without the use of the foot clutch. Unique knobs also make it easier to distinguish between the two.

Transmission controls on PowrQuad™ transmission models:

A single transmission control is located to the right of the operator. This control features the ability to shift through gears within a range using the rabbit button to increase gears and the turtle button to decrease gears. A range change can be completed with this control, as well by moving through A-D ranges similar to a traditional range controller. To aide in ease of operation, operators can use the integrated declutch button rather than the foot clutch to change ranges.

A foot throttle with a platform pedal is located on the right side of the operator. The pedal is positioned for ease of use, yet does not clutter the floor. The hand throttle is easily accessible on the right hand console.

Engaged by either foot, the differential lock pedal is placed on the floor.

Hydraulics controls
The color-coded bands on the levers, which control triple rear SCVs, correspond to the color of the dust cap and the SCV valve they control.

PTO controls and speeds
The 5ML features electrohydraulic PTO engagement on all models.

The push/pull knob on open station tractors is conveniently located beside the hand throttle on the right-hand side of the operator. When the PTO is engaged, a light on the instrument panel will illuminate and PTO speed is indicated by target bars. Models equipped with a PowrReverser transmission have a 540/540E rpm shiftable PTO while models equipped with a PowrQuad transmission have a three-speed PTO, 540/540E/1000 rpm.

Enhancing operator safety, the tractor does not start with the PTO engaged. An alarm sounds if the operator attempts to leave the seat with the PTO engaged. The PTO shaft is protected by a hinged shield.

Mechanical front-wheel drive (MFWD) controls
All four-wheel drive (4WD) axles are equipped with the engage-on-the-go MFWD. This toggle switch is now located on the right-hand console.

Lighting controls – Multi-position dial
The five-position lighting package is straightforward with the lighting control switch on the right side of the steering column. The switch positions are: off, warning, work light, transport 1 (warning and high-beam headlights), and transport 2 (warning and headlights). A turn-signal lever is located on the left side of the steering column for quick and easy use.
