The New Holland MZ-H Zero-Turn-Radius Mower is a series of compact, high-performance lawn mowers designed for efficient and precise lawn maintenance. This document details the specifications for four models: MZ16H, MZ17H, MZ18H, and MZ19H.

Function Description

The MZ-H series mowers are zero-turn-radius machines, meaning they can turn on a dime, offering exceptional maneuverability around obstacles and in tight spaces. This capability significantly reduces mowing time and improves efficiency compared to traditional lawn tractors. The primary function is to cut grass, with various deck sizes and engine powers to suit different property sizes and grass types. The dual hydrostatic drive system, where each wheel is independently driven by a separate motor, is central to their zero-turn functionality and precise control. Optional attachments further extend their utility beyond just mowing, allowing for tasks like grass collection and snow removal.

Important Technical Specifications

Engine:

MZ16H: Features a 16 hp (11.9 kW) Briggs & Stratton engine with 1 cylinder.
MZ17H: Equipped with an 18 hp (13.4 kW) Kohler Command engine, 1 cylinder.
MZ18H: Utilizes an 18 hp (13.4 kW) Briggs & Stratton engine, 1 cylinder.
MZ19H: Powered by a 19 hp (14.2 kW) Kawasaki engine, 2 cylinders. All models feature air cooling, full pressure lubrication, a starter key with safety interlock, and a dual element air cleaner, all of which are standard. Fuel capacities vary: 2 gallons (7.6 L) for MZ16H and MZ18H, and 5 gallons (18.9 L) for MZ17H and MZ19H, providing extended operation times for larger properties.

Drive System:

All models employ a dual hydrostatic drive system, which is fundamental to their zero-turn capability. This system uses two pumps, each driving a separate motor at each wheel, allowing for independent control of wheel speed and direction.

Max Forward Speed: 6.0 mph (9.6 kph) for MZ16H and MZ18H; 7.0 mph (11.3 kph) for MZ17H and MZ19H.
Max Reverse Speed: 3.0 mph (4.8 kph) for MZ16H and MZ18H; 3.4 mph (5.5 kph) for MZ17H and MZ19H. The implement clutch is electric across all models, providing convenient engagement of the mower deck.

Brakes:

Service Brake: Hydrostatic Dynamic Braking is standard on all models, utilizing the hydrostatic drive system for braking.
Parking Brake Lock: Automatic engagement with steering levers in neutral for MZ16H, MZ17H, and MZ18H. The MZ19H features a manual parking brake on the LH lever.

Electrical System:

All models operate on a 12-volt electrical system.

Charging System: 9 amps for MZ16H, 15 amps for MZ17H, 16 amps for MZ18H, and 13 amps for MZ19H.
Battery: All models feature a 260 cca (cold cranking amps) battery.
Headlights: Optional on all models.

Wheels and Tires:

Front Casters: All models use 10 x 4, 4-ply tires.
Rear Tires:
- MZ16H and MZ17H: 18 x 7.5-8, 4-ply.
- MZ18H: 18 x 8.5-8, 4-ply.
- MZ19H: 18 x 10.5-10, 4-ply. The larger rear tires on the MZ18H and MZ19H suggest improved traction and stability, especially for the more powerful MZ19H.

Dimensions (in. / cm):

Length, overall: 72.6 (184.4) for MZ16H and MZ18H; 77.5 (196.9) for MZ17H and MZ19H.
Width, overall (with deck deflector down): Ranges from 50.7 (128.8) for MZ16H to 65 (165.1) for MZ19H.
Width, overall (with deck deflector up): Ranges from 46.0 (116.8) for MZ16H to 58 (147.3) for MZ19H.
Height, overall: Ranges from 39 (99.1) for MZ16H and MZ18H to 41 (104.1) for MZ19H.
Wheelbase: Ranges from 47.0 (119.4) for MZ18H to 52.1 (132.3) for MZ17H and MZ19H.
Turning Radius, inside rear wheel: Zero degrees for all models, confirming their zero-turn capability.
Net weight, estimated: Ranges from 516 lb (234 kg) for MZ16H to 680 lb (309 kg) for MZ19H.

Mower Decks:

MZ16H: 42-inch side discharge (standard). 2 spindles.
MZ17H: 44-inch side discharge (standard). 3 spindles.
MZ18H: 48-inch side discharge (standard). 3 spindles.
MZ19H: 52-inch side discharge (standard). 3 spindles. All mower decks include anti-scalp gauge wheels as a standard feature, preventing damage to the turf on uneven terrain. Optional mulching kits are available for all decks.

Usage Features

The MZ-H series prioritizes operator comfort and control.

Steering: Dual padded lever hydrostatic steering with hydraulic dampening is standard across all models, providing smooth and responsive control.
Operator Station: Features include standard armrests, a cup holder, and a storage bin for convenience.
Seat Type: Contoured, high-back seats are standard on all models, with adjustable fore and aft positioning on MZ16H and MZ18H for personalized comfort.
Footrest: Adjustable on MZ16H and MZ18H.
Front Casters: Double yoke design for durability and smooth maneuvering.
Safety Features: Standard starter key with safety interlock ensures the mower can only be started when safe conditions are met.

Maintenance Features

While specific maintenance schedules are not detailed in this document, several design elements suggest ease of maintenance:

Air Cleaner: Dual element air cleaner is standard, offering superior filtration and likely extending engine life by preventing dust and debris from entering the engine.
Full Pressure Lubrication: Standard on all engines, ensuring consistent oil delivery to critical engine components, which is vital for engine longevity and reduced wear.
Battery: The 260 cca battery is a common size, suggesting easy replacement if needed.
Spindles: The number of spindles (2 or 3 depending on deck size) is a key maintenance point for blade replacement and bearing checks.
Optional Attachments: The availability of attachments like grass catchers and front blades suggests a modular design, allowing for easier replacement or servicing of these components.

Attachments & Accessories:

Grass Catchers: 2-bag grass catcher (6 cu. ft.) is optional for MZ16H, MZ18H, and MZ19H. A 2-bag vacuum grass catcher is optional for MZ17H.
Front Blades: 48-inch front blade is optional for MZ16H, MZ17H, and MZ18H. A 56-inch front blade is optional for MZ17H and MZ19H, extending the mower's utility for snow removal or light grading.
Front Lights: Optional on all models for improved visibility during early morning or late evening operation.
Smooth-tread front tires: Optional for MZ17H, which might be preferred for certain turf conditions or to minimize turf disturbance.

Overall, the New Holland MZ-H series offers a range of zero-turn mowers with varying power and deck sizes, designed for efficient, comfortable, and precise lawn care, with options to enhance their versatility.
