Used 4LZ-2.5 Second hand KUBOTA Wheat Rice Combine Harvester Machine Pro 688Q
Product introduction
1. diesel engine with reliable performance
Kubota's self-made 49 2kw turbocharged diesel T-engine with high power and low fuel consumption. The vertical water-cooled 4-cylinder turbocharged diesel engine system is adopted as power, which provides more output power and starting torque with less fuel than the conventional spherical diesel engine.
2. Wide track
Wide track can work more smoothly in wet fields than ever before. 275mm ground clearance, not easy to accumulate mud, and better adaptability to rotten fields.
Long threshing cylinder with large diameter
The longitudinal oil flow threshing system adopts a long threshing drum with an ultra-large diameter of 620mm and a drum length of 1790mm, which can carry out more efficient and accurate harvesting and threshing operations.
3. Comfortable operating seat
Comfortable seats are installed, so the operator will not get tired even if he works for a long time.
4. Operate the handle
Experiment rotation and header lifting with one handle.
5. Control HST with one stroke
The walking system (hydrostatic transmission) pioneered by Kubota allows you to control forward and backward with only one handle, and at the same time, you can adjust the driving speed under the conditions of normal harvesting, high yield, wet crops, wet and rotten fields harvesting and walking. At the same time, HST with increased capacity can save more effort than before.
6. Harvest reversing mechanism
When the feed inlet of the header is blocked, it can rotate reversely to discharge the blocked material.
7. Adjustable guide plate
The angle of the deflector can be adjusted according to the state of crops to achieve the best threshing effect.
