■YM Tractor
Yanmar’s all new YM357A (Output:57 hp) tractors feature a host of innovations and new technology that will streamline operators’ work and create new value for the regions’ farmers.
Many farmers in Southeast Asia cultivate both rice in wet paddies and a range of dry field crops, from corn to sugar cane and others. Fields are often tilled by contractors who demand highly efficient light-weight and reliable 50-60 hp tractors, to lower costs and maximize their income. The YM series meets these demands in a highly functional and attractive package featuring styling by world-renowned designer and Yanmar Holdings Director and Member of the Board, Ken Okuyama.
The all-new YM is right choice for farmers because it is a total tractor that can work both rice paddies and dry fields, and can haul loads, and features advanced geolocation functions towards improving the work efficiency and profitability of farmers and operators.

Some of the YM tractor’s advanced features include:

SMARTASSIST Remote (SAR) allows users to access vital operational information about their tractors through an intuitive user interface which can even be accessed from a smartphone. SAR’s geolocation features allow the operator to see exactly where their equipment is and how it is working. SAR can also issue warnings when machinery is operating outside preset parameters or if the equipment moves beyond designated boundaries. The result is reduced downtime, greater earnings and peace of mind for farmers. SAR is standard to the YM357A.

Powerful and Fuel-efficient Engine
Yanmar’s YM tractor comes with a powerful and efficient direct-injection TNV diesel engine that realizes high power with low fuel consumption and superb durability.
The engine incorporates several innovative features that improve performance and reduce wear:
- Monoplunger fuel injection pump atomizes fuel at high pressure
- Unique combustion chamber shape for improved combustion
- Double air cleaner for reduced piston wear

Optimum gear selection for work
Gear ratios are matched to work speed for best performance with 8 forward and 8 reverse gears. Gear ratios widely overlap all speed ranges to deliver the best torque for the work speed, using less fuel and contributing to owner profit.

Versatile Workload
The YM is great on dry fields or paddies and can also haul loads.
Great ground clearance is the key to powering on in muddy conditions or passing over crops without damaging them, while a maximum turning angle of 55º gives a turning circle that is the envy of its class.
Able to use a variety implements, The YM can perform a wide range of work and boasts a specially mated newly-designed rotary tiller that limits soil traveling into the rotary for reduced power loss.

Ergonomic comfort
With a flat deck, full synchromesh transmission and deluxe suspension seating, the YM is comfortable and easy to operate with intuitive controls for fine-tuned precision work. Operators can stop or start PTO operation with one touch of a button.


The YM Tractor will go on sale in Southeast Asia from early 2019 and is expected to be progressively deployed globally in coming years.
