  • Page 17 Replace any damaged manufacturer-installed warning labels and place warnings on equipment parts not previously labeled. In addition, consider painting them a bright color, perhaps with wide stripes. Be aware of wrap points and be alert to their danger. Crush Points Crush points are created when two objects move toward each other or one object moves toward a stationary object.

  • Page 28: Putting The Tractor In Motion

    Operation Description 2.6 Putting the Tractor in Motion IMPORTANT ISSUES To prevent tooth breakage of the gears in the transmission or early clutch damage, do not start the engine in the High gear range. Release the parking brake before starting to avoid damage to operating parts. When putting the tractor into gear or shifting gears, the clutch pedal should be depressed to disengage the clutch and prevent gear teeth in the transmission from being broken or the clutch from being damaged.
  • Page 29 Operation Description IMPORTANT ISSUES: When turning the front wheel sharply, to prevent damage to the hydraulic steering system, the steering wheel may pull back slightly. This is to prevent the hydraulic steering system from being overloaded. Before making turns or backing up during field work, make sure that any towed machinery is lifted from the soil to avoid damage.

  • Page 30: Shifting Gears

    Operation Description 2.8 Shifting Gears The tractor uses the main gearshift lever (A), the high/low gear shift lever (B) and the forward/reverse shuttle gear lever (C) to manage gear shifting. The tractor has four gear settings and two gear ranges, L for low speed and H for high speed.
  • Page 31 Operation Description Select the speed of the tractor based on the type of work being done in order to prolong the life of the engine and various parts. Only by doing so will you be able to get the best performance out of the tractor and the most longevity.

  • Page 32: Differential Lock

    2.10 Front Drive Axle Use The NorTrac 40XT and 50XT series of 4-wheel drive tractors can be used for normal operations in the field and on wet and soft soil. If only rear wheel drive is used, the traction may be insufficient. When this happens, connecting the front drive axle will increase the traction of the tractor and reduce the slippage.

  • Page 33: Tractor Braking

    Operation Description NOTE: When driving on a hard road, the front wheel tires will wear rapidly and the left and right sides of tire tread patterns will be worn unevenly. For this reason, it is a good practice to switch the left and right tires on occasion.

  • Page 34: Tire Assembly And Disassembly

    Operation Description WARNING: 1. Never leave the tractor unattended with the engine running. Leaving the tractor running could result in the tractor accidentally moving and going out of control, which can result in a serious accident. 2. If the tractor has to be parked on a slope, engage the gears. Set the shuttle gearshift to forward on an uphill slope and reverse on a downhill.

  • Page 35: Counterweights

    Operation Description IMPORTANT ISSUES: The inflation pressure for the front and rear tires on a 4-wheel drive tractor should be the same in order to prevent the tires from being worn unevenly. 2.13.2 Tire Removal and Refit Tire Removal Special tools are needed to assemble and disassemble a tire. Contact a qualified tire service center to replace tires.

    Maintenance Instruction 4.6 Front Drive Axle Adjustment 4.6.1 Front Axial Clearance and Toe-In (see Figure 4-5) The front axle of the tractor uses an adjustable tubular front axle, which is located in the front of the diesel engine. The carrier and the diesel are fixed by 6 screws; the pendulum shaft is supported by both ends of the carrier and is sheathed with a sleeve welding assembly.
  • Page 72 Maintenance Instruction 4.6.2 Front Axle Adjustment (2 Wheel Drive Model)  Front-Wheel Bearing Axial Clearance Adjustment (Figure 4-6) : The normal axial clearance of front-wheel bearing should be 0.05–0.15 mm. During operation, it should be adjusted if the clearance increases to 0.4 mm. When adjusting, jack up the front wheel, remove the bearing cap, pull out the cotter pin and turn the castle nut until the bearing clearance is eliminated.
  • Page 73 Maintenance Instruction 4.6.4 Front Drive Axle Structure and Adjustment (Figure 4-7) (4 Wheel Drive Model) The power of front drive is transmitted to the front central drive via the transfer case. The power is distributed into the half-axle on two sides by the front central drive, then transmitted to the final drive to make the driving gear turn. When working in the field where the conditions are poor, mud and water can easily get in to the front/rear lining, which will cause end face wear and the axial float to increase.
