2021 Tractor 90HP Tractor Rubber Crawler Tractor Nfg 902 for Agriculture

Product Description

Discription
The rubber crawler tractor has the advantages of small grounding pressure, large adhesion and good passability in paddy field, so as to realize protective tillage in paddy field.At the same time, dryland work compacts the soil much less than wheel tow.Rubber crawler tractor adopts hydraulic control planetary differential mechanism, small turning radius (can be turned in situ), flexible turning turn, reduce the field turning transfer and other auxiliary hours, rotary tillage work efficiency is 10-20%, ploughing work more than 20%.The rubber crawler tractor adopts the whole frame structure, good rigidity and high clearance from the ground. It is especially suitable for the paddy field where the mud bottom is deeper and the wheeled tractor is difficult to operate.It is an ideal power machine for paddy field cultivation in rice producing areas.

Features: 1. Height of chassis.Compared with the original NF series tracked tractors, the minimum ground clearance is increased by 110mm to 530mm, which will not support the bottom even in extremely deep muddy fields, greatly reducing the possibility of land trap.
2. Many gears.Forward 12 gear + back 12 gear, according to different working conditions, choose the best gear matching, so that the engine always in the best power performance, the best fuel economy performance, the best work efficiency to find the appropriate balance, while achieving the purpose of power, fuel saving and high efficiency.
3. Enhanced transmission.The strengthened design of gear, bearing and output shaft can meet the requirements of high horsepower tracked tractor and improve the reliability of the whole machine.
4. Side shift.Shift joystick side, convenient to get on and off, increase the foot movement space, better control, more comfortable operation.
5. Enhanced chassis.The bottom frame is designed to be strengthened, and the parts that are easy to hang grass and block mud are optimized to reduce the blocking resistance of the track by blocking mud, saving oil and increasing efficiency.
