Bison 12 hp

Bison 12 hp – a powerful and multifunctional walk-behind tractor, which is the most popular model of the brand in Russia. This equipment is often converted into a mini tractor, which makes the scope of its use even wider.

Walk-behind tractors are usually divided into 3 classes (light, medium and heavy). Bison 12 hp belongs to the latter type.

The gearbox of the equipment has a high and low range of speed selection, which adds to the comfort of work. The transmission itself includes 3 forward and 1 reverse gears (8 gears thanks to the ability to operate at low speeds). The gears of the element are made of stainless high-carbon steel and have a huge service life. The gear shift mechanism is reliably protected from air access and filled with oil, which is replaced in rare cases. The torque transmission shafts at the junctions with the drive and transmission are sealed with oil seals. By locking the differential, driving the walk-behind tractor is noticeably easier. So, the operator can deploy it while staying in one place. True, the rotation itself is quite difficult due to the large mass of the device.

The equipment is controlled using handles where key elements are installed (clutch, gear shift, etc.). Dark time of day for the Zubr 12 hp model. won't be a problem since it comes with a halogen headlight. Large wheels with a chevron tread pattern eliminate slipping even when heavily loaded.

The walk-behind tractor delivery set includes the device itself, an improved active cutter of increased size that covers the wheel track, an improved gearbox with an additional power take-off shaft, a plow and a specialized adapter that includes a wheel and a seat. The last element allows you to convert the equipment into a mini tractor, which will be especially useful in small farms. Using the Zubr 12 hp model. you can perform the following operations:

• soil treatment;
• loosening the soil;

Model Zubr 12 hp – the most powerful and most popular in the brand’s line.

Motoblock Zubr 12 hp It is characterized by increased reliability, but again it requires periodic maintenance (oil change, bolt tightening, inspection). In addition, after a long period of inactivity or purchase, equipment must be run in. The process begins with checking the oil level and filling the fuel tank. Then you should start the engine and let it run quietly for several minutes. At the second stage of running-in (0.5-1 hour), the speed begins to increase. It is important for the owner to work in all gears, engaging them one by one, and not giving full power. At this moment, maximum grinding of the walk-behind tractor elements occurs, and the operator himself chooses the optimal position and speed for him. The last stage (6-8 hours) consists of operating the walk-behind tractor at a slightly above average load with a variety of attachments. After break-in, it is recommended to perform maintenance.

User manual

Included with any Zubr walk-behind tractor is an instruction manual, which must be carefully studied before starting to work with the motorized device.

Thanks to this, the efficiency of the installation increases and fuel consumption is reduced. The water cooling system used in this unit is more efficient than an air system and allows it to work for a long time in difficult conditions. Heat is removed in a ventilated condenser. Lubricant sprayed onto the elements by a gear pump performs a similar function.

Reviews

• I have been using Zubr 12 for several years. Now there is no fundamental difference in the brands of walk-behind tractors, since most of them are made in China. The hardware is similar, but only the body changes. I can say one thing about my walk-behind tractor - the Zubr 12 is a very reliable piece of equipment. It is definitely not suitable for a small area, since it is rather professional special equipment with all its advantages and disadvantages. There are no complaints about the assembly of this model - everything is done well, nothing unscrews, does not creak or interfere. Working on a walk-behind tractor is quite convenient. True, Bison 12 walks and turns with difficulty. The model tilts slightly, so it requires a lot of effort to maneuver. In terms of efficiency and maintenance, the special equipment pleased me. One tank of fuel was enough for my plot (50 acres).
• 4 years ago my wife convinced me to buy a walk-behind tractor. We have a large plot of land, and I’m tired of constantly paying money for tractor services. Initially we chose a mini tractor, but in the end we decided to take a compact but powerful walk-behind tractor. After a lot of browsing and reading reviews, I chose the Zubr 12 hp. the special equipment had a relatively considerable cost and a good resume. After a short run-in, I immediately tried the unit in action. The walk-behind tractor coped well even with heavy soil, and broke up lumps very well. Bison 12 hp – heavy special equipment. This is both a plus (working with the ground and transportation is simplified) and a minus (operating the unit becomes quite labor-intensive). When working, I quickly found a comfortable position, but still took breaks. I had a version with a manual starter and had no problems starting it in cold weather.
• Bison 12 hp – multifunctional special equipment that will be an excellent assistant in a large farm. The model is equipped with a diesel engine and a reliable transmission. This unit consumes a lot of fuel - over 2 liters per hour. Compared to analogues, the indicator is not large, but when processing large areas, you have to refuel several times. True, most operations with a walk-behind tractor take a little time. So, a plot of 30 acres was planted with potatoes in a few hours. Cultivation is again much faster than manual cultivation. I can’t say anything about the problems, since I haven’t experienced them in 3 years of work. The handles and paint have worn off a little and extraneous noise has appeared in the case. Everything else is good.
• I bought a Zubr 12 hp walk-behind tractor. seven years ago. I moved with my family to the countryside and needed a good car. There was no money for a tractor, so I had to buy a walk-behind tractor. I did not consider low-power versions. Bison 12 hp I liked the small price, good characteristics and nice design. I took a model with a manual starter (I didn’t want to overpay for an electric starter). The special equipment starts up well even now, since its engine is of a professional level. I immediately bought attachments and lugs for the walk-behind tractor. I practically didn’t use the latter, since the Bison has 12 hp. had already good cross-country ability (the vehicle is heavy and takes on any soil). There were practically no breakdowns, and I bought all the spare parts in the nearest city (Saratov). For rural areas Zubr 12 hp. would be a great solution.

About the manufacturer

Walk-behind tractors are produced in China . Now there is nothing special about this, since a lot of equipment from other brands comes to us from there. Prices, however, are no lower than for products from Russian factories, but the build quality is in no way inferior.

If you decide to purchase a Zubr walk-behind tractor, the price in Russia will completely satisfy you.

For most citizens, it is not prohibitive, although it all depends on what kind of walk-behind tractor you are counting on - only light walk-behind tractors are considered cheap enough, and for each additional horsepower you will need to pay extra.

This also applies to other useful options that are not available in cheap equipment. But no matter how expensive a walk-behind tractor you decide to buy, it will still be cheaper than a tractor, even a miniature one.

Spare parts

But, nevertheless, for each repair you will need spare parts. There can be no exception here, since most parts cannot be made independently. For example, one of the reasons for the drop in engine power is the piston.

Motoblocks Zubr, Cayman, Patriot, Texas, Foreman, Crosser, Viking, Forza, although they are wear-resistant and suitable for use in difficult conditions, their engines do not last forever. A decrease in performance due to wear of the cylinder-piston group - scratches on the piston, retraction or breakage of the piston rings requires their immediate replacement.

Spare parts

The only option is to purchase a complete piston kit. The same applies to other parts; in principle, you can replace old, worn or broken ones even while on the road or in the field. Such repairs are not at all unusual, because you never know where something unexpected might happen.

But thanks to the prerequisites and timely inspections of equipment, due attention and maintenance, anything related to serious breakdown can be avoided.
