Product Details
Kubota 4LZ-2.5 (PRO688Q) Full Feed Crawler Harvester Product Introduction
Fast walking system
1. Reliable diesel engine performance
Kubota's self-produced high-power, low fuel consumption 492kw turbocharged diesel engine. The power adopts a vertical water-cooled 4-cylinder turbocharged diesel engine system, which provides greater output power and starting torque with less fuel than conventional spherical diesel engines.
2. Wide track
Wide track can work more smoothly in wet fields than ever before. 275mm ground clearance, less prone to mud accumulation, better adaptability to rotten fields.
Efficient threshing system - with outstanding processing capacity and minimal losses
Large diameter and long threshing cylinder
The longitudinal oil flow threshing system adopts a long threshing drum with a diameter of 620mm and a drum length of up to 1790mm, which can perform more efficient and precise harvesting and threshing operations.
Simple and convenient operating system
1. Comfortable operating seat
Equipped with comfortable seats, the operator will not feel tired even after working for a long time.
2. Operating handle
Use a handle to experiment with rotation and lifting of the cutting table.
3. One stick control HST
Kubota's pioneering walking system (static hydraulic transmission) allows you to control forward and backward with just one handle, while also adjusting the driving speed during normal harvesting and high-yield, wet crop, wet rotten field harvesting, and walking situations. Meanwhile, HST with increased capacity can be operated more effortlessly than before.
4. Harvesting reversal mechanism
When the feeding inlet of the cutting table is blocked, reverse rotation can be performed to discharge the blockage.
5. Adjustable deflectors
The angle of the guide plate can be adjusted according to the condition of the crops to achieve the best threshing effect.
