Gasoline engine Yamaha MX300 is characterized by high power output and low fuel consumption. Automatically adjustable rpm regulator ensures that engine immediately responds to the load change. Balance shaft significantly reduces vibration level providing comfortable working conditions. Engine service life amounts to 5,000 hours, which significantly exceeds walk-behind tractor service life.
«MultiAGRO» reduction gearbox is of gear-and-chain type. However, in difference from analogs, due to a special kinematic scheme this product encompasses the whole pulling and speed range required for the operation of this walk-behind tractor. Due to this, it is enough for you to engage a convenient gear on «NEVA» MB23 MultiAGRO walk-behind tractor and work efficiently not tuning to the limited capabilities of other walk-behind tractors. Another advantage of the reduction gearbox is in its sleek shape. Owing to it the gearbox touches ground less and does not leave wide furrows during operation. As a result, after tillage the soil obtains a neatly expanded surface. «MultiAGRO» reduction gearbox is a proprietary development of JSC «KO-Neva».
The whole set of «MultiAGRO» reduction gearbox gears includes 8 forward and 4 reverse gears. They, in turn, are divided into high gears (4+2) and low gears (4+2). Selection of a particular gear for the execution of one or another work facilitates the work and allows reaching the best results. It is important to select the gear properly when tilling different types of soil. For example, it is better to till cultivated soil in the 2nd gear. It is more efficient to till swardy soil in the 1st gear.
Turning shield installed on «NEVA» MB23 MultiAGRO YAMAHA (MX250) PRO walk-behind tractor is intended to facilitate product maintenance. This option becomes even more urgent when it is necessary to rearrange the belt on double-grooved pulleys to take advantage of the set of high gears.
Wheels disengagement function is used when it is necessary to turn a walk-behind tractor practically on the spot. It is convenient when it is not enough space for U-turn. Special levers are provided to disengage the drives of reduction gearbox semi-axes. Left lever (black) disengages the left semi-axis (left wheel). Right lever (red) disengages the right semi-axis (right wheel). Besides, this function can be used when a walk-behind tractor is operated on cutters or grip hooks.
Pulling force of «NEVA» MB23 MultiAGRO YAMAHA (MX250) PRO walk-behind tractor reaches 300 kgf. It means that the machine is capable to execute heavy-duty works and till complex soils with a high quality. Besides, improved pulling capability contributes to better passability and facilitates handling of the walk-behind tractor.
Gear shifter allows easy and fast changing walk-behind tractor operating conditions. The shifter is located on the left handle of the steering bar, which is convenient for the user. To shift gear it is enough to put out your hand and put the shifter in the required position. Availability of two neutral positions allows fast shutting down of the walk-behind tractor if problems occur when working in reverse gear.
Doubler lever is intended to change the gear range. This lever is located on the reduction gearbox of the machine. When the lever is shifted in the «turtle» position the selected gear is switched over to the low one. When the lever is shifted in the «hare» position the gear becomes low. Gear range is selected depending on the operating conditions and personal preferences of the users.
The steering bar of «NEVA» MB23 MultiAGRO YAMAHA (MX250) PRO walk-behind tractor is adjusted in height and turning angle. Setting of the suitable steering bar height reduces the load on the operator. Change of the steering bar turning angle is required to improve machine mobility when working in a space-limited environment (near fences, flower beds, greenhouses).
«NEVA» MB23 MultiAGRO YAMAHA (MX250) PRO walk-behind tractor efficiently tills all types of soils on 4 and 6 cutters. To accelerate tillage of easy soil it is possible to increase the number of cutters simultaneously installed on a walk-behind tractor to 8 pieces. Tillage width varies from 86 to 170 cm (depending on the number of cutters). It is necessary to install flaps on the walk-behind tractor to ensure safety during tillage.
