Solenoids 67a, 67 of valves 67, 68, 69
b, 68a, 68b, 69a, 69b, etc. are connected and provided.

The liquid crystal monitor 17 and various lamps 16 are connected to the output section of the meter panel controller 7c. Tractor 10 configured as above
Then, the shift control is executed as in the flowchart showing the outline of the shift control program shown in FIGS.

The flowchart shown in FIG. 8 is a control flowchart relating to the shift control according to the first, second and eighth aspects, and is a process executed by the traveling controller 7b. When the engine key switch of the tractor 10 is turned on, the controller 7b proceeds to STEP 1 and
The connection status and the setting status of various sensors and setting devices, etc.
Read in M. At the same time, the meter panel controller 7c displays the fuel display and the vehicle start condition on the liquid crystal monitor 17. Subsequently, when the engine 12 is started, the rotational speed n of the engine 12 is determined in STEP2. When the rotational speed n is smaller than a predetermined value α, that is, when the accelerator is held at a low speed, the operation is started. Assuming that the vehicle speed is to be reduced from now on, the process proceeds to STEP 3 in which the second shift control state is established, and every time the shift up switch 3a is turned on, the switching is performed so as to increase by one step from the current shift position. Solenoids 67a, 67b, 68a, 68b, 69a, 69b of control valves 67, 68, 69
And the solenoids 67a, 67b, 6 of the switching control valves 67, 68, 69 are moved down by two steps from the current shift position each time the shift down switch 3b is turned on.
8a, 68b, 69a, 69b are energized.

When the engine speed n is in the working range, that is, in a state where the engine speed is lower than the so-called full throttle position, the process proceeds to STEP4, which is the first shift control state. The solenoids 67a, 67b, 68a, 68b, 69a, 6 of the switching control valves 67, 68, 69 are moved up by one step from the shift position.
9b, the solenoids 67a, 67b, and 67b of the switching control valves 67, 68, and 69 are moved down by one step from the current shift position each time the shift down switch 3b is turned on.
The current is supplied to 68a, 68b, 69a, 69b.

When the engine speed n is larger than the predetermined value β, that is, when the vehicle is in the full throttle state, the process proceeds to STEP 5 in the second shift control state on the assumption that the vehicle is going to travel on the road. Each time the up switch 3a is turned on, the solenoids 67a, 67b of the switching control valves 67, 68, 69 are moved up by two steps from the current shift position.
The switching control valves 67 and 6 are energized so that the gears 67b, 68a, 68b, 69a and 69b are energized, and each time the shift down switch 3b is turned on, the gear is lowered by one step from the current shift position.
8, 69 solenoids 67a, 67b, 68a, 68
b, 69a, and 69b are energized.

When the switch is operated, the meter panel controller 7c is operated by the shift controller 7b.
Prior to the energization command, the target shift position corresponding to the switch signal is displayed on the liquid crystal monitor 17. Accordingly, the shift control device of the tractor 10 can finely increase or decrease the vehicle speed during work, can greatly increase or decrease the vehicle speed during non-work, and can constantly increase or decrease one step at a time. Thus, the gear can be quickly shifted to the target shift position.

In the flowchart, the tractor 10
Is determined on the basis of the engine speed, but based on the rotation state of the PTO shaft of the vehicle and the value of the lift arm angle sensor 8b as shown in the flowchart of FIG. In other words, when the lift arm 37 is rotating upward, the process proceeds to STEP 4 in the second shift control state on the assumption that the vehicle travels on the road or moves between work sites. The shift up switch 3a and the down switch 3b are ON
Each time, the solenoids 67a, 67b, 68a, 68b, 69a, 69b of the switching control valves 67, 68, 69 are energized so as to move up or down by two steps from the current shift position.

Similarly, as shown in the flowchart of FIG.
A work / road traveling (non-working) mode changeover switch 8c for designating the traveling state or the work state may be provided, and the shift pattern may be switched by an operator's own setting. That is, when the driving mode is set, the process proceeds to STEP 4 which is the second shift control state, and each time the shift up switch 3a and the down switch 3b are turned on, the switching is performed so as to shift up or down by two steps from the current shift position. Solenoids 67a, 67 of control valves 67, 68, 69
b, 68a, 68b, 69a, 69b are energized. On the other hand, when the operation mode is set, the solenoids 67a of the switching control valves 67, 68, 69 move up or down by one step from the current shift position each time the shift up switch 3a and the down switch 3b are turned on. ,
Power is supplied to 67b, 68a, 68b, 69a, and 69b. Further, the monitor display of these shift positions is the same as described above, and thus the description thereof will be omitted.

It should be noted that the number of jumps for upshifting and downshifting in the above-described second shift control state may be set to two for both the upshifting side and the downshifting side, and more than two steps depending on the form of the vehicle. May be set in a plurality of stages, or may be finely changed as the speed approaches the highest or lowest speed.
Further, when the current shift position is the lowest or the number of steps near the highest speed where a predetermined jump cannot be performed, the speed is changed so as to switch between the lowest speed and the highest speed.

Next, the invention according to claims 7 and 8 will be described. Shift switches 3a, 3b of the tractor 10
Is configured to shift up or down by one step or two steps for each ON operation, but when the ON signal is continued for a predetermined time, as shown in FIG. 11, automatically switches to the second shift state. ing. Here, STE first
At P3, the duration of the switch ON signal is measured. If the duration is continued for a predetermined time or longer, the currently stored shift position is increased or decreased by one step while the switch operation is detected. At the same time, the stored value is displayed on the liquid crystal monitor 17 while continuously switching, for example, from 1 to 2 to 3 by communicating with the meter panel controller 7c. Thereafter, the shift position when the continuous ON signal disappears is determined, and the shift control position is set as a target and the switching control valve, the switching control valve, and the switching control valve 6 are set.
7, 68, 69 solenoids 67a, 67b, 68a,
Power is supplied to 68b, 69a, and 69b to switch the shift position of the first or second main transmission.

Thus, the operator can change the speed of the shift switch 3
When a and 3b are continuously pressed, by shifting to the second shift state prior to the first shift state, the shift time can be shortened and the operability of the shift operation can be improved. Next, the turning control mounted on the tractor 10 will be described. Generally, in the field work of the tractor 10, it is often necessary to make a small turn on the headland, and the longer the headland width is, the longer the time required for the subsequent headland leveling work is, and the lower the work efficiency is. There is. In addition, when the work start end for lowering the work machine 9 and the work end end for lifting the work machine 9 are not constant during the leveling work along the longitudinal strip of the field, the headland is roughened and the head leveling work is performed. There is a problem that it is sometimes difficult for the vehicle body to perform a swing operation.

Accordingly, in the tractor 10, the work implement 9 is automatically raised at the same time as the depression operation of the clutch pedal 24 is detected, and then, when the clutch pedal 24 is depressed, the vehicle automatically reverses for a predetermined time and switches to forward movement. The front wheel speed-up drive and the brake on the rear wheel 14 inside the turn are applied. Thus, the operator senses that the front wheel of the tractor 10 or the front end of the vehicle body has contacted a ridge and the like, and depresses the clutch pedal 24 to uniformly raise the working machine 9 and further lower the working machine 9. Therefore, the work start end and the end end can be uniformly aligned, and the work efficiency during headland leveling work can be improved.
