McCormick: functionality and value

McCormick USA says its new MB Series is designed for customers looking for a lower specification tractor that offers both functionality and value.

Three models in the series — the MB55, MB65 and MB85 — offer fuel-efficient diesel engines, two transmission options, robust hydraulic flow, and easy access to the operator's platform. Power ranges from 58 to 81 engine hp (54 to 74 pto hp).

“These tractors offer the power, versatility and functionality needed to accomplish any job on the farm,” says John Sargeant, vice-president of marketing and logistics for McCormick USA. “They're also ideal for loader, light tillage and general farm work.”

Powered by the latest generation 3- and 4-cylinder Perkins 1100-series diesel engines, the series' naturally aspirated engines meet Tier 2 emission levels, run quieter and offer high torque rise capabilities for pto and tillage applications.

A cross-flow cylinder head positions the intake and exhaust manifolds on opposite sides of the engine to prevent preheating of inlet air. This results in a more efficient combustion process, as inlet air is cooler. The engine also features a rotary-type injection pump, and cold starting capabilities are improved by using glow plug pre-heaters to ensure quicker starting in cold environments.

Two transmission options are offered in the series: A standard synchromesh-shuttle transmission with 12 forward and reverse speeds offers speeds up to 18.6 mph. The optional synchromesh-shuttle transmission with creep offers 24 forward and 12 reverse speeds as low as 0.17 mph or 15 fpm. Both transmissions feature a 4-speed gearbox and mechanical shuttle that are fully synchronized for easy, smooth gear and directional changes.

The shuttle incorporates a neutral position ideal for operations that require periodic pauses between forward and reverse changes. An optional gate on the forward/reverse shuttle control lever engages the creep function.

A three-positioned range lever is located to the side of the shuttle lever in the center of the operator's platform. This lever is non-synchronised and can only be shifted when the tractor is stationary.

All models are fitted with a dual plate clutch made of a long-lasting cerametalic material for outstanding durability. The pto drive clutch is incorporated into the main drive clutch housing and uses an organic-faced drive plate. Operated by a hand lever, the pto clutch is totally independent of the main drive clutch.

All McCormick MB models feature a standard mechanically engaged rear differential lock. To engage, the operator simply pushes the foot pedal on the operator's platform. To disengage, the operator removes his foot from the pedal to release.

The MB Series also offers optional hydraulic front and rear differential locks that can be simultaneously engaged by simply pressing the foot pedal on the right side of the platform. The easy operation encourages engagement when field conditions dictate that extra traction is required.

Disengagement of the hydraulic differential lock is achieved by pressing one of the brake pedals. The front differential lock is a hydra-lock, positive-locking system and ensures positive traction at all four wheels.

The MB Series features a standard 540-rpm and ground speed pto. The pto clutch is independently operated using an engagement lever located on the right-hand side of the steering column. To select the independent (engine-drive) pto, the operator simply moves the pto speed selection lever, located to the left of the operator's seat, to the rearmost position. The selection of proportional (ground speed) pto is accomplished by moving the pto speed selection lever to the forward position. Ground speed pto is useful with pto driven trailers, sprayers and other implements where it is important to keep pto shaft speed proportional to ground speed.

The 4-wheel drive requires a simple mechanical engagement to provide additional traction and stability. The front axle provides a 55-degree steering angle, ensuring good turning capabilities for outstanding maneuverability. The hydrostatic steering is a self-contained system with its own dedicated pump and a separate oil reservoir to provide effortless steering without having to share hydraulic power with other systems. The MB Series also offers optional front fenders on all MFD models.

The MB Series features an open center hydraulic pump for hitch and remote functions. The pump generates a robust 13.8 gpm of hydraulic flow at the two standard remotes. A mechanical hitch control with a top link draft sensing feature provides standard lift capacity of 5,700 pounds.

To meet the demands of heavier 3-point hitch-mounted equipment, all models may be equipped with (two) optional assistor rams to increase the lift capacity to 8,140 pounds. This allows the operator to match the lifting capacity of the MB Series tractor to fit his needs — giving lifting capabilities for a greater range of equipment.

Linkage is standard Category II and link ends are the fixed ball type. The stabilizers are telescopic, allowing either fixed mode to hold the lower links in position or floating mode to allow movement when in work.

A one-piece front-hinged hood allows access to maintenance areas of the radiator and air cleaner. Even when the tractor is fitted with a front-end loader, users have easy access to components like the battery and steering reservoir. A 22.7-gallon fuel tank can be filled from ground level. Located under the hood, the fuel tank is protected by a separate fuel door to accommodate convenient filling.

The MB Series features unrestricted access to the operator platform with the major controls positioned along the center line of the transmission. All models come equipped with a 4-post ROPS frame which can also be fitted with an optional rigid sun-canopy.
