Curve a
The first forward gear is engaged, the ground speed control lever is moved from its 0 position to the front. Curve section 1: When starting, the ground drive variable displacement pump HPV 105 swivels from a volumetric displacement of 0 towards 105 cm³/rev. The ground drive variable displacement motor HMV is set to its maximum input volume of 105 cm³/rev. on Jaguar 850, 830 up to serial no. 492 00135 135 cm³/rev. on Jaguar 900, 890, 870 and 850, 830 from serial no.: 492 00136 Now: - maximum propulsive power is reached; - the max. ground speed is approx. 9 km/h. Curve section 2: The ground drive variable displacement pump HPV 105 is set to 105 cm³/rev. of volumetric displacement. The ground drive variable displacement motor HMV swivels from an input volume of 105 cm³/rev. to 85 cm³/rev. for Jaguar 850, 830 up to serial no. 49200135 and from 135 cm³/rev. to 85 cm³/rev. on Jaguar 900, 890, 870 and 850, 830 from serial no. 49200136 Now: - the propulsive power decreases; - the ground speed increases up to approx. 14 km/h.
Curve b
The second forward gear is engaged, the ground speed control lever is moved from its 0 position to the front. Curve section 3: When starting, the ground drive variable displacement pump HPV 105 swivels from a volumetric displacement of 0 towards 105 cm³/rev. The ground drive variable displacement motor HMV is set to its maximum input volume of 105 cm³/rev. on Jaguar 850, 830 up to serial no. 49200135 135 cm³/rev. on Jaguar 900, 890, 870 and 850, 830 from serial no. 49200136 Now: - the propulsive force is smaller than in the first gear - the max. ground speed is approx. 19 km/h. Curve section 4: The ground drive variable displacement pump HPV 105 is set to 105 cm³/rev. of volumetric displacement. The ground drive variable displacement motor HMV swivels from an input volume of 105 cm³/rev. to 85 cm³/rev. for Jaguar 850, 830 up to serial no. 49200135 and from 135 cm³/rev. to 85 cm³/rev. on Jaguar 900, 890, 870 and 850, 830 from serial no. 49200136 Now: - the propulsive power decreases; - the ground speed increases up to 20 km/h or 25 km/h.
