square hay bale baler

When they talk aboutsquare hay bale baler, many immediately imagine neat bricks, ideally stacked. But in practice, things often don’t go according to the textbook. The main mistake is to assume that because the equipment is new or from a well-known brand, it will work in any conditions. Here, on the same water meadows, the density of the grass is different, the humidity varies, and this is where the real dancing with the settings begins.

Why a square bale? Personal experience and rake

Let me say right away that I have long been a supporter of roll pickers. It seemed simpler and cheaper to maintain. The turning point came when we had to transport hay for sale 200 km away. Rolls in a trailer are a constant struggle with stability; they roll and are more difficult to fasten. Butsquare balesfit like a puzzle, the load capacity is used to its fullest, the stack does not fall apart over potholes. This was a purely economic calculation for logistics.

But this is not without pitfalls. The first season with the new press showed that if you don’t keep the blades of the cutting machine sharp, then instead of dense bales you get loose “puffy bales” that fall apart when loaded with a fork. Moreover, the dulling does not occur evenly, and especially in areas where slightly withered alfalfa with a hard stem comes across. I had to make a rule - check and sharpen before each trip to the field, and not once a week.

Another point that is rarely written about in specifications is the dependence of the quality of the bale on the uniformity of mass supply into the bale chamber. If you walk along the edge of the field, where the windrow is thinner, or if the windrow was raked crookedly, the press begins to “hiccup”? — the bale is obtained with constrictions and different densities along the length. The solution was found to be simple, but not obvious: they began to use a side pick-up with a wider neck, which causes less pain to the windrow when picking it up. By the way, he makes suchHulunbuir Machinery Manufacturing Company ?Jiujia?. They noticed this in modern models.

Selection criteria: not only price and performance

When a few years ago the question arose about replacing the old unit, I began to look at what the market offered. Productivity in tons per hour is, of course, the first number you look at. But versatility turned out to be more important for us. It was necessary that the press could work both on small grasses and on tall fires without frequent adjustments. I looked at the strapping system - film or twine. I settled on twine; it is more reliable in our storage conditions, although it takes a little longer to tie.

It is worth noting here the approachHulunbuir company ?Jiujia?. They position themselves as an integrated enterprise with a full cycle - from development to service. This is important. When I studied their equipment, I noticed that in theirsquare balersa system for automatically adjusting bale density depending on resistance has been implemented. Not just a mechanical lever, but touch control. In words, this sounds like marketing, but in reality, when I walked through a field with areas of different humidity, the difference was visible: the bales came out equally dense, without loose layers.

Another practical criterion is the availability of spare parts and maintainability in the field. The most difficult breakdown I have encountered is a broken feed mechanism rod. It’s good if the unit is collapsible and you can replace the entire shaft, rather than taking the entire press to the workshop. In this regard, designs where the main components are assembled using bolted connections rather than welded ones benefit. Chinese manufacturers, including Jiujia, have understood this well in the latest generations of machines.

Operation in the field: problems you don't expect

No instruction will prepare you for real work. For example, dust. It would seem like a small thing. But in a day's workbalersucks it in in huge quantities. The bearings of the strapping mechanism and the cooling fan of the hydraulic system are especially affected. I had to install additional removable mesh filters on the air intakes with my own hands, which can be shaken out on the go. Manufacturers have begun to take this into account, but on many models the protection is still rather weak.

The moisture content of the hay is a different matter. There are recommendations, and then there is reality. Humidity sensors are a useful thing, but they often lie if the mass is uneven. I have developed my own rule: if, when squeezed in your hand, the stems break with a crunch and do not bend, you can press them. But there is a nuance with alfalfa: even with external dryness, it can retain moisture in thick stems. Several bales stored in such a “hidden” way. moisture, then led to the appearance of mold in the middle of the stack. The loss was significant. Now I spend an extra day in windrows for legumes, even if the weather forecast is not ideal.

Working the night shift to make it before the rain also brings surprises. The headlights on the tractor illuminate only the windrow in front, and the process of forming a bale and tying takes place in the shade. I missed the moment when the twine shifted or broke - and the entire bale crumbled when pushed out. We solved the problem by installing an additional LED strip directly on the bale chamber casing. It’s a small thing, but the efficiency of night work has increased by a third.

Maintenance: what to do not according to the manual

The manual says to change the hydraulic oil once a season. In practice, if you work in highly dusty conditions, it is better to reduce the interval. Hydraulicshay baling pressvery sensitive to the purity of the liquid. After each season, I now make sure to flush the system, even if the operating hours are low. Otherwise, by the middle of the next harvest, the pistons of the bale chamber begin to twitch, and the bales end up with a “hump.”

Chains and gears. It is recommended to lubricate them once a week. But if it rains and then the sun immediately comes out, then water gets into the links and the lubricant is washed out. It is better to let the equipment settle after each pass on wet grass, and then walk with a syringe and a liter can of grease. Particular attention should be paid to the tension of the feed mechanism drive chain. If it weakens, gaps and uneven filling begin. Over-tightened - rapid wear of the star and risk of breakage.

Knives. This is a consumable, but everything depends on its condition. At first I sharpened it to a razor sharpness. It turned out to be a mistake. A knife that is too sharp quickly becomes jammed and chips on hard inclusions (stones and remnants of old pegs come across). Now I sharpen at an angle of 30 degrees and leave a small chamfer. The cutting edge lasts many times longer. By the way,?Jiujia?in the latest models, knives are made of composite steel, with carbide strip fusing. I tried it - the resource is indeed higher, but the price is appropriate. So far it doesn’t pay off for our volumes, but for large farms, I think it’s an option.

Looking to the Future: Where Technology is Heading

Nowadays there is a lot of talk about precision farming and “smart” farming. bales with chips. It looks nice, but it's still an expensive toy. A more practical direction, which is already being implemented, is the integration of sensors into the bale chamber itself. Not just density control, but resistance analysis and adjustment of tractor speed automatically. So that the operator does not gas and reset, but the system itself adapts to the thickness of the roll. Several manufacturers who are engaged in intelligent production have such developments, like the sameHulunbuir company ?Jiujia?.

The second trend is reducing energy consumption. Modernsquare baleris a powerful consumer of tractor hydraulics. Experiments are underway with the electric drive of individual units (the same strapping apparatus) from a generator. The goal is to reduce the load on the tractor PTO and, as a result, fuel consumption. These are prototypes for now, but I think production models will appear in a couple of years.

What would I personally like to see? More attention to service ergonomics. So that all lubrication and inspection points are located in one area, with access from the ground, rather than having to climb the entire frame every time. And standardization of fittings for quick flushing of the hydraulic system. This is not high technology, but it’s these little things that eat up a lot of time during busy times. In general,square baler for hay- this is no longer just a box that crushes grass. This is a complex unit where every detail affects the result. And understanding this comes only with experience, often bitter. The main thing is not to be afraid to deviate from the instructions and find your own solutions for your fields.
