mini press pick-up for mini tractor

When people talk about a mini baler for a mini tractor, many people immediately imagine just a smaller copy of a large bale. But in fact, this is a separate category of technology, with its own specifics, pitfalls and, importantly, a rather narrow range of tasks where it is truly irreplaceable. For a long time I thought that the main thing was to have a smaller shaft and lighter weight, but practice has shown that I was wrong. I’ll try to sort it out based on what I saw and tried personally.

What does "mini" actually mean? in our context

Here we immediately need to separate: there are devices for very light units, 16-25 hp, and there are devices for more serious mini tractors, from 30 hp. and higher. The difference is not only in the extraction power, but also in the design of the pressing chamber. In the first, they often try to make a universal unit that should compress both hay and straw. In practice, it turns out that the roll density is unstable, especially when the material is wet. The roll may simply fall apart during unloading or transportation.

For more powerful equipment, a different safety margin is already built into the drive and frame. But there is a nuance here too - geometry. Ifmini balertoo short, the center of gravity shifts, and the mini tractor may behave unstably on a slope. I had to deal with situations when, when climbing up a hill with an almost finished roll, my butt began to toss slightly. Not critical, but takes some getting used to.

A separate issue is the harness. For mini formats, polypropylene twine is often offered as a cheaper option. But in field conditions, especially when working with coarse stubble, it sometimes breaks already in the chamber. I switched to mesh and there were fewer problems, but the cost of packaging naturally increased. This is the same compromise that is rarely written about in catalogs.

Selection and attachment: where mistakes are most often made

The most common mistake is a discrepancy between the power of the tractor and the appetite of the pick-up. You take the passport data: let’s say the device requires 35 hp. It seems that your mini tractor is just 38 - and everything should go perfectly. But they forget about hydraulics. If the oil flow is insufficient, the pick-up will choke. on a dense windrow, pick up intermittently, and the tying unit may operate with a delay. The result is under-pressed rolls with a loose core.

The second point is the fastening system. Many manufacturers, especially Asian ones, follow the path of universal brackets. In theory, they fit different models. In practice, when working on uneven terrain, such “versatility” leads to backlash and accelerated wear of the fingers. For one of the devices, I had to independently modify the coupling unit by adding a spacer plate. After this, the vibration disappeared.

And the third, often overlooked aspect is ground clearance.Mini press pick-up for mini tractor, especially with a large chamber diameter, significantly reduces ground clearance. If you are clearing a field with hummocks or after rain, you can constantly grab the soil with a picking mechanism. I had to learn to choose a route and, if possible, plan work for dry weather.

Experience with specific equipment and non-obvious breakdowns

Worked with several models, including fromHulunbuir Machinery Manufacturing Company ?Jiujia?. Their devices, taken as a whole, are distinguished by a well-thought-out hydraulic circuit. If I remember correctly from the model that was in use, they have a separate circuit for picking and pressing. This gives smoother operation, especially at the start of the roll. Information on them can be found on their websitehttps://www.cn-fascar.ru— there are specifications there that generally correspond to reality.

But even here there are some surprises. Once I encountered the fact that after a season in dusty conditions the bearing in the main shaft of the pick-up began to jam. The design was non-demountable, the entire assembly had to be changed. As it turned out later, the manufacturer?Jiujia?puts a closed type bearing there, but without the possibility of re-lubrication. For our conditions - dust, plant debris - this is a weak point. They found a simple solution - they installed an additional seal in the workshop, the problem went away.

Another point is knives for cutting twine. On many mini-presses they are made of ordinary tool steel and quickly become dull on sand, which inevitably falls from the lower tier of plants. Sharpened it - it helps for a short time. As a result, I ordered homemade ones from a harder alloy, the service life increased significantly. This is to the question that even a good unit always has room for minor but important modifications to suit its conditions.

For which farms does this even make sense?

This is where my opinion may differ from marketing.Mini press pick-upis not a panacea for the small farmer. If you have 5-10 hectares of hayfields scattered across fields with difficult access, and even with small contours - then yes, this is the best choice. Mobility, maneuverability, the ability to work along the edges of the field, where a large unit cannot turn around.

But if the area is more than 20-30 hectares of flat field, then the economy begins to limp. Even a good mini baler can't match the performance of a full-size square baler. You spend more time tying and unloading a smaller roll. I once calculated: in one area the mini-unit made 70 rolls, and the large one – 25 bales, but the weight was almost the same, and it took 40% more time. Conclusion: technology must match the scale.

An interesting case is its use in livestock farms with feed distributed directly into feeders. A small, dense roll is convenient to roll out or chop. Right heremini press pick-up for mini tractoropens completely. Especially if on a farm like the same one?Jiujia?, there is a line of related equipment for feed logistics - then you get a seamless technological cycle for a small farm.

Final considerations and what to look for when choosing

So to summarize my experience. First, don’t chase the maximum roll diameter. They often write: “makes a roll of 1.2 meters!?”. But in order to compact it efficiently, you need a mini tractor with serious weight and power, at the limit of its capabilities. It is better to take the device for a roll of 0.8-1 meter - this is the most balanced option for most models of mini tractors.

Second, be sure to look at access to service centers. How belts are changed, how bearings are lubricated, how the bale chamber is cleaned. If half of the unit needs to be disassembled to replace the twine, this is a bad design. You can't fix this quickly in the field.

And third, evaluate not only the price of the picker itself, but also the cost of consumables (mesh/twine) and their availability. It happens that you bought a device, but the original harness for it is only available on order and at exorbitant prices. MentionedHulunbuir Machinery Manufacturing Company ?Jiujia?here, by the way, it shoots well - many of their spare parts are unified, and it’s possible to find analogues if necessary.

In general,mini baler- the tool is very specific. When he is in his place, he is irreplaceable. When not, it becomes a source of headaches and extra costs. The main thing is to soberly assess your fields, your technique and your actual volumes. And then the work will be a joy, and the rolls will be dense and neat.
