Frequently Asked Questions. We not only have nutrition experts, but we’re always on the cutting edge of innovation with every aspect of a TMR mixer. Sharing some commonly asked Jaylor questions may clear things up for you. Please feel free to ask any other questions you may have.


Effective fiber creates a scratch factor causing cud chewing, which produces saliva that neutralizes acid, improving rumen function while minimizing feet and leg problems. This means your high producing cows stay on feed with less digestive upset. Less stress means better feed intake, which leads to improved milk production.

Total Mixed Ration, which is both a concept and way of life. The TMR Concept considers they way cows eat and makes it easier for farmers to ensure the correct nutrients are being consumed. Dairy farmers know the quality of feed helps ensure the quality of the milk. Cows are a little bit like kids. They pick through their ration and pick out the tasty smaller grains. For nutritionists this is a cause for concern because the cow’s rumen will drop significantly in PH. This causes acidosis (upset tummy) or laminitis which at the barn level manifests into sore feet. Both conditions can become chronic or acute with serious impacts on production in the herd. Traditionally farmers have fed their cows hay followed by wet silages, then grains, proteins, vitamins, and minerals. This is an extremely labor intensive and ineffective method because it creates a poor ration environment and acidosis. With compromised nutrition levels farmers are forced to spend money on extra feed, veterinary costs and labor. Farmers needed a way to produce healthier and more cost effective feeds. That’s where TMR comes in, it’s been the single most influential factor in increased milk production in the last 10 years. Since the early 1970’s TMR feeding has gained in popularity, but has always been limited by the amount of hay that can be incorporated in the ration.

Jaylor machines are designed for rugged performance with very little maintenance required. Regular machine maintenance consists of: greasing moving components such as PTO joints, bearings, periodically checking oil levels, the condition in the gearbox, inspecting knives, and other wear items and replacing as necessary.Review your Operator’s Manual for complete instructions and regularly calibrate scales.

The plastic reservoir, located at the front of the mixer, provides a quick and easy viewing of the fluid levels for the planetary gearbox.
This simplifies service by easily monitoring fluid level and condition at all times giving you trouble free operation and peace of mind.

Knives are a wear item. They are manufactured with a tungsten carbide coating for durability and wear resistance.

However, because of varying farm operations and processes, it is difficult to estimate an accurate life expectancy for knives under so many operating conditions. Foreign matter such as rocks and excessive amounts of sand will inherently affect the life of the knives. High hourly use per day will also affect their life span.

The two-speed transmission is helpful in areas such as starting up under load while a marginally powered tractor is being used to power the machine. In low gear, it provides an approximate 20% torque mechanical advantage versus direct or high gear. It’s also helpful to slow the auger(s) down if the mixing is too aggressive for certain types of feed commodities.

Yes, in fact most people don’t realize they can. Mixing large volumes of hay in the ration is one of the biggest advantages Vertical TMR mixers provide over previous methods of TMR feeding.

While we cannot guarantee increased milk production numbers, we have confidence that our machines will increase your production. Please refer to our customer’s testimonials; they come from varying farm environments and areas of the world that thank us for increased production.

Our machines have been university tested and under proper test conditions have proven results. We highly recommend consultation with a reputable feed nutritionist, in combination with our machines, for optimal results.

Trailer models turn 39 to 41 revolutions per minute (RPM) at full Tractor PTO speed (Either 540 or 1000 RPM depending on the model).

Each machine will be different based on the farm and farmer. As a rule of thumb, a dairy cow eats an average of 4 – 6 cu ft of feed per day.

A farmer with a 425 cu ft machine could be feeding a herd of 100-150 cows, once a day. However, another farmer with the same machine could be feeding multiple times a day to a much larger herd of 300-400 animals. Therefore, the number of cows a specific machine can feed depends on the farmer’s preferences, the hours spent feeding per day, and the total herd size. We’d be happy to help you spec a model size for your operation – just drop us a line or call.

Each machine’s weight is different. Please review our mixers individual specifications found in our ‘Product’ section.
