Kubota Grand L40 Series,Transmission Features from Bagley Tractor & Equipment

HST PLUS (Hydrostatic Transmission)

Tackle any task with ease and efficiency. With starting precision, the new HST Plus's automated control of both the HST pump and motor gives you optimal performance, regardless of the task, working conditions, or operator expertise. This new technology incorporates the popular light and smooth pedal feel of Kubota's traditional HST to provide the Grand L40 with a more comfortable, easier-to-operate, and higher-performance HST than ever before.

HST Plus
Hydraulic Servo System
Kubota's new HST Plus includes a hydraulic servo mechanism that decreases the amount of pressure required to depress the HST pedal. A popular and proven feature on previous Kubota models, this mechanism creates a more responsive pedal, which in turn delivers smoother handing and more control, whatever the load size. In addition, the system helps to reduce vibration, shock, noise and fatigue to provide a gentler ride and improved performance.

Kubota's advanced technology has made operating a tractor as simple as driving a car.

Kubota's new HST Plus offers professional and novice users maximum HST performance by giving optimal control of both the hydraulic pump and the drive motor - all with simple operation. Thanks to new functions that regulate the pump swash plate and can adjust the motor swash plate between two stages, you can get the most out of the HST Plus, whether you prefer manual or automatic control.

Hydro Dual Speed (H-DS) HST Hi-Lo Function

Kubota's HST Plus gives you more control. Already featuring three range shift speeds, it now includes a lever or shift between high and low speeds. Once your preferred range shift speed is set, you can easily shift the H-DS between the high and low speeds while moving. And with a simple touch of the Mode Selection button, you can activate the Auto H-DS for automatic Hi/Lo shifting.

Load Sensing Mode Selection

The Grand L40 boasts a revolutionary Load Sensing feature that, if it detects a drop in engine RPM, will automatically regulate HST pump and motor activity. This feature makes operating the Grand L40 easy for almost anyone. Simply press the Mode Selection button, choose your preferred mode, and feel the difference.

With Kubota's advanced Load Sensing Mode Selection, control is yours with the touch of a button. With three modes to choose from, transmission operation can be adjusted to accommodate your immediate needs. Each consecutive press of the button will select the next mode, from Mode 1 to Mode 3, and back again.

Manual Mode This mode offers manual control of all transmission functions. It's perfect for those experienced operators who enjoy complete control of the tractor.

Stall Guard Thanks to the Grand L40 Stall Guard's load-sensing technology, you don't have to worry about engine stall. By pressing the Mode Selection button, Kubota's new Stall Guard function automatically regulates the burden on the engine and prevents it from stalling, without any need for sensitive pedal operations.

Auto H-DS with Stall Guard Ideal for tasks involving major changes in engine burden, this mode activates both the Stall Guard and the Auto H-DS (Auto Hydro Dual Speed) to maximize the ease of operation, letting you work more effectively. The Auto H-Ds enables automatic Hi/Lo shifting, and, combined with the Stall Guard, maintains the torque and allows the tractor to continue bearing heavy loads, drive on slopes and keep you working.

HST Response Control
Kubota knows that different challenges require different responses. Now the HST response speed can be adjusted with a simple turn of a dial. If your task requires a quick response, you can turn the dial to the FAST setting. This setting is ideal for use during loader-related chores. If the job at hand needs a more gradual response, as used for turf work, set the dial to SLOW. When your preferred response speed has been selected, you won't need to make any more adjustments with the foot pedal. It's that easy.

Auto Throttle Advance
Thanks to the new Auto Throttle Advance feature, driving the Grand L40 is as simple as driving an automatic-transmission car. This function links the HST pedal and the engine throttle, synchronizing tractor speed and engine revolution. This greatly simplifies tractor operation and helps reduce fuel consumption. Now, all you need to do to control tractor speed and engine revolutions is depress the HST pedal. This feature is especially handy when moving between locations or when towing a trailer.

GST Glide Shift Transmission

Kubota's exclusive GST transmission features electronically controlled clutchless operation. With just one lever, the Grand L40 offers 12 forward and eight reverse, synchronized shift-on-the-move gears. Featuring an optional creep speed, the GST system can be upgraded to 24 forward and 16 reverse gears. With its quick, smooth and precise shifting, the Grand L40 virtually eliminates engine power loss during front loader use or implement work. Having more speeds at your command will reduce overall work time and fuel consumption for increased operating efficiency.

FST (2WD/4WD models)

Fully Synchronized Main and Shuttle Transmission
For economical and reliable transmission, you want the Grand L40 FST. This efficient 8-forward and 8-reverse gear transmission is synchronized for smooth, shift-on-the-go operation. Now, all you need to do is simply step on the clutch, shift and go. With Kubota's Carbon-Cone Synchro-Shuttle, faster and smoother forward/reverse directional changes are easier to attain. This Carbon-Cone design makes shuttle shifting lighter and easier for instant responses, especially during front loader work.
