Key features of the eHydro transmission are: Infinite ground speeds, even at full throttle, allow the operator to match the speed of the tractor to the job. Sauer-Danfoss eHydro transmission is used for reliable operation.
Durability features include: Large forged trunnion shaft with larger support bearings that reduce vibration and noise. Transmission oil cooler cools transmission oil for longer transmission life. Key John Deere advantage. Key advantages over competitive hydro model tractors: Some competitive hydrostatic tractors use a treadle pedal toe-heel design foot control for operation of the hydro Requires the operator to use both toe and heel to change direction, resulting in increased operator fatigue Some competitive hydrostatic tractors have their individual turning brakes on the same side as their treadle pedal This configuration makes it virtually impossible to operate both the turning brakes and hydro pedal at the same time on these competitive models This configuration also makes it difficult to ''inch'' the tractor forward or rearward for example, when attaching to implements.
A deluxe seat on the 4R models can swivel 15 degrees to either side and provides greater comfort and less fatigue when operating rear implements. The swivel feature also allows the operator to easily get in and out of the seat. The additions of premium work lights allow for longer work hours and are easily installed on the ROPS.
All 4R models feature integrated hydrostatic transmission controls on a single panel. All 4 Family tractors come standard with an open operator station. The tightly sealed cab keeps out dust and noise, as well as microscopic allergens while featuring climate control for year-round comfort. The cab also enables degree views with forward work lights, front windshield wiper and an integrated radio antenna. No other speed control switches are on dash. I understand they did away with load match switch on newer models.
Aug 9, 2. Try this. If that doesn't work here's what it says about load match "Using LoadMatch eHydro LoadMatch enables the operator to prevent the engine stalling during heavy load applications such as operating with a loader. This feature is turned on and off using the display mode switch 1. Turn key switch to ON position. No error codes should be displayed.
If any errors are displayed, activate the display mode switch A to acknowledge the error. The last edited command will display, either Coast or Load.
If Load is not displayed, use left or right turn signals to select the Load command. Activate the display mode switch A to edit the LoadMatch setting. When the desired setting is displayed, activate the display mode switch A to store the setting. The LCD B will flash the entered command twice and then change to the normal mode.
Aug 9, 3. I am curious about exactly what you are expecting it to do. Number of cylinders. The 3R Series Tractor is available with an exclusive three-range electronic hydrostatic eHydro transmission. This ensures that the components are matched to each other, providing maximum efficiency.
The electronic hydrostatic transmission is ideally suited for jobs where productivity is a must, such as loader or mower applications. Key features of the eHydro transmission are :.
John Deere's Twin Touch foot controls offer several key advantages over competitive hydrostatic transmission HST tractor models. Integrated eHydro features The eHydro convenience controls have been integrated into a single module. All of these features are standard on the 3R models, and deliver an easier and more comfortable user experience. An automotive-style cruise control is standard equipment on the 3R Series Tractors. Cruise control is electronically engaged and disengaged and is located on the right-hand operator console.
If torque requirements increase significantly, the transmission will reduce the tractor's drive speed to compensate for the increased load on the transmission, maximizing torque to drive wheels and minimize stalls. Controls automatically adjust LoadMatch compensation depending on the tractors application.
PTO applications require less engine speed fluctuation, therefore adjusts the amount of droop depending on PTO speed. This adjustment increases efficiency and optimizes engine speed and torque output based on tractor application. While typically left on, LoadMatch can be turned off with the right-hand console controls. It offers seven settings for adjusting the rollout or decelerate when the pedal is released.
SpeedMatch, standard on the 3R Series Tractors, further enhances the eHydro cruise control functions by allowing the operator to preset maximum speed. Once this feature is engaged, the operator must stroke the travel pedal fully to meet the operator preset speed. This function will improve accuracy and safety, particularly at lower travel speed applications.
Rotary tilling or spraying applications are examples of where SpeedMatch can be applied. SpeedMatch will work in both the forward and reverse set speeds. Sauer-Danfoss is a registered trademark of Sauer-Danfoss, Inc.
