## 4. Conclusions

- (1)
- The mechanism and working principle of the wheel-track high clearance chassis of rape windrower were introduced, and the models of mathematical relations between the walking performance, stability performance and the eccentricity of the chassis frame were built.
- (2)
- Three-dimensional model and dynamic simulations of a wheel-track high clearance rape windrower were conducted using Pro/E and RecurDyn software. When the machine was driven at the same speed, the walking speed changed little with the increase of eccentricity, and the coefficient variation of speed decreased gradually. The average driving torque and the coefficient variation decreased first and then increased. Minimum driving torque and the coefficient variation were obtained when the eccentricities were 1484 mm and 1584 mm. The chassis frame eccentricity was defined as 1500 mm, according to the theoretical calculation and simulation analysis. The maximum angle of uphill and downhill was 28° and the maximum height of the crossing ridge was 266.15 mm.
- (3)
- The performance experiments of wheel-track high clearance rape windrower in flat hard ground and rice stubble field were carried out. The test showed that the speed running on flat hard road was 0~20.22 km/h and the minimum turning radius was 5.965 m; the working speed in rice stubble field was 0~9.12 km/h and the minimum turning radius was 6.498 m. The machine could steadily climb the slope of 20°.
- (4)
- A new kind of wheel-track high clearance chassis was developed, which could hang on the swath header over than 3.5 m wide. All parameters of the chassis met the design requirements, and the work efficiency increased over 100% compared with the existing two-tracked rape windrower. This provided another kind of equipment for rapeseed harvesting in the Yangtze River Basin.
