This says it all:
Maximum speed | 18 mph (29 km/h) |
---|---|
Power output | Engine: 204 hp (152 kW) |
Tractive effort | Maximum: 14,500 lbf (64 kN) |
Brakeforce | 14 long tons-force (139 kN) |
Edjt: I think the problem wasn't with the performance but the gear changing while everything was in motion... And having something robust enough to get it in motion.
