Apache Power to the Ground Technology Delivers

Horsepower rating is important – but only when it’s powering your sprayer forward. Apache Sprayers mechanical-drive transmission with patented Apache POWER-TO-THE-GROUND™ technology delivers more horsepower where and when you need it most.

Horsepower versus Torque

Most ag sprayers require more horsepower because of their weight.  Not Apache, in fact, our ag sprayers are engineered to be light in the field for less soil compaction and equipped with horsepower and torque to conquer the toughest field conditions.  Despite simple construction, Apache Sprayers are rugged, dependable and built with the torque-converted power you need to get the job done. 


A full 90 percent of Apache Sprayers horsepower is transferred to the ground, compared to 70 percent from other sprayers.  In fact, the Apache’s lighter construction provides more Power-to-the-Ground™ than competing sprayers. That way you get a lot more from your horsepower.

Experience the power and performance of Apache Sprayers.
Request a Free field demo and we’ll prove it!

Don’t just take our word for it. Apache owners say it best.

There is no issue with power. We have sunk up to one foot in the peat beds, but the Apache just pulls through, and we have never been stuck. Even on the hills, it has never lost power”.

Mark and Scott Jencks
Hawkeye, Iowa

Unmatched Traction

All Apache Sprayers feature a flex-frame construction that ensures all four wheels are always on the ground. Lock-up torque converter and limited-slip differential create constant contact with the ground rear wheels and keep them turning no matter the field conditions.

Power Conversion

A torque converter doubles the engine’s ability to push the Apache through tough terrain, while a JCB limited-slip differential allows for sharper turns and better traction.

Sprayer Weight Matters

Heavier machines consume more fuel. Ever wondered what makes them heavier in the first place? Typically, it’s due to additional parts and components that you may someday have to replace. More horsepower is required to move that machine and its chemical product load. Lighter sprayers like the Apache get the same job done – while using less horsepower and fuel – and create less soil compaction for increased crop yields.

Apache Sprayers mechanical-drive, with patented POWER-TO-THE-GROUND™ technology, delivers more horsepower where and when you need it most”.

Equipment Technologies Research and Development

Reliable Cummins Engines

Simplicity and reliability, that is what you get with Apache Sprayers.  In fact, our Cummins Performance Series V engines are simple to maintain and they get more done while costing you less to operate.  The Performance Series V engines are featured in the AS850, AS1050, and AS1250/XP.  The AS650 and HS1100 feature the Tier4 final engines from Cummins.  The partnership between Cummins and Apache allows the already fuel-efficient Apaches to become even greater energy misers on the farm – cutting fuel consumption by 8 – 15% across all models.

Ag Herbicide Buying Tips: Learn From Past Wins and Losses

ag herbicide smart buying tips

Account for what’s worked and buy smart to sustain ag herbicide efficacy.

Every growing season presents its own unique challenges. A weed that hammers a crop one year may not make so much as a minor appearance in the same fields the following year. With such variability in potential weed pressures from year to year, ag herbicide availability may be affected, making it important to know when and what product to buy to be prepared for the next weed outbreak.

In today’s tight grain marketplace, efficiency with crop inputs like herbicide applications is a high priority for many row crop and small grain farmers. Any good herbicide strategy elevates preparedness and enables the farmer to act quickly when weed pressures pop up. Mother Nature always plays a large role in what weeds will cause headaches each year, but there are a few ways to be ready by focusing on the variables that you can control.

What has worked in the past?

The process starts before you’re even to the point of making a herbicide purchase, and it begins by looking back and relying on production records from previous years. Are there any patterns to when specific weeds were problematic in your fields? Look closely at the previous year’s data; in some cases, weed seeds can overwinter and become a problem across more than one growing season, according to Iowa State University Extension Field Agronomist Meaghan Anderson.

“Rather than just falling back on old habits, analyze your [herbicide] program closely to look for improvements for future years,” Anderson said in a university report. “Surviving weeds from this year will affect weed pressure in next year’s crops. Identifying this season’s management successes and failures will make weed management and herbicide purchase decisions easier this winter.”

When is the best time to buy herbicide? 

Taking this deeper look at your herbicide program from year to year can help with not only what you buy, but when you buy it. Though it may be old habit to wait until specific weed pressures develop before you purchase the necessary ag herbicide product, University of Illinois Crop Science Specialist and Weed Scientist Aaron Hager encourages farmers to make earlier, more informed purchase decisions based on field-specific production data. Doing so typically offers cost savings over buying product during the growing season, especially if the weed pressure is more geographically widespread.

“Usually, fall purchases offer a bit better price compared to in-season purchase,” Hager said.

Environmental conditions can also give you a feel for what specific types of products will perform best. Knowing your soil types, as well as having a basic idea of the range of weather conditions your crop may face next year are helpful in determining which herbicide products should perform best in your fields. In addition to any weed pressures you faced this year, these variables can help nail down things such as herbicide mode of action in what you purchase in planning for next year’s crop.

“Weeds that are exposed to the herbicide can survive application for any number of reasons, and determining why is important for avoiding repeat problems. The main factors influencing the activity of preemergence herbicides are soil type and rainfall. Was the application rate appropriate for the soil type, or was rainfall adequate to activate the herbicide and make it available in the weed seed germination zone?” Anderson said. “Postemergence herbicides are influenced by many factors, including weed size, environmental conditions, spray additives and spray coverage. Spraying weeds that exceed the maximum size specified on the herbicide label is probably the number one cause of postemergence herbicide failures. Finally, weeds may survive due to the presence of herbicide resistance within the field. When resistance is just beginning to evolve within a field, escapes are usually found in discrete patches, and it is often possible to find surviving plants immediately adjacent to dead individuals of the same species.

What are other things to consider?

“The final step is to use this information to make decisions for next year. Surviving weeds may warrant a change in product or herbicide site of action, increased herbicide application rates or use of a more innovative approach, like a layered residual program,” Anderson added.

As with any crop protection product or mechanism, it’s best to scout your fields and take note of specific weed pressures you’ve faced. The best time to do so is in the middle of the growing season, Anderson said. It’s also important to pay close attention to herbicide labels to ensure you’re planning for and purchasing products that you can apply during the optimal treatment windows.

Do you have the right equipment to apply ag herbicide when it’s needed most? The right sprayer can go a long way to ensuring your herbicide applications are cost-effective and provide the weed control you need. Check out the features on the latest Apache Sprayer models to see which one is right for your operation.

G&J Ag: Reintroducing Apache Sprayers to Southeast Missouri

Longtime dealers; maintenance technicians see Apache Sprayers as a good fit for variety of farm operations

A lot of farmers around Oak Ridge, Missouri, know Tim Johnson and Duane Green. And now, the business partners are bringing a familiar name back to the area’s machinery sector.

Johnson and Green operate and manage G&J Ag in Oak Ridge. The dealership and maintenance shop also sells and services equipment from MacDon, Demco, Unverferth, McFarlane, Bush Hog and McCormick and will be providing maintenance and repair for Apache Sprayers. Sales and parts inventory from Equipment Technologies dealership Southern Application Management in Batesville, Mississippi will also provide additional benefits to owners.

“We used to have an Apache Sprayers dealer here, and they sold well over the years. People here know the Apache Sprayers name,” Johnson said. “Duane and I have both built up quite a customer base here, so bringing Apache back to this area seemed like a good fit for everyone.”

Meeting growing producer needs

It’s a good time for G&J to add Apache Sprayers to its sales and service lineup. Consolidation in the machinery sector has created a resurgence in interest among producers in working with a dealer. That’s especially true with companies like G&J, with both Johnson and Green having decades of experience in sales and service, including previous experience with larger manufacturers.

“We’ve sold a lot of sprayers over the years,” Johnson said. “We are basically handling parts and service. We’re bringing in a dedicated technician and our ultimate goal is to keep him busy year-round with Apache Sprayers. We hope to bring a lot of Apache Sprayers to this part of the country.”

Why Apache Sprayers align with G&J customers

A few components and qualities of Apache Sprayers will be key to that kind of expansion among the wide range of farm size and crop mixes that characterizes the G&J customer base. Their customers, Green said, range from 500-20,000 acres, with many around 1,500-2,000 acres. Despite that size variability, the high spraying demand and common ground conditions make the light weight of Apache Sprayers a popular feature in row crop and cotton acres.

“Other sprayers are getting so heavy and you have 15 different controllers for the boom and other components,” Johnson said. “Apache Sprayers are straightforward, simple to maintain and farmers I talk to love their light weight and simplicity. We have a lot of ‘gumbo’ bottom ground where weight becomes a major concern. These machines work well in conditions like those.”

Adding Apache Sprayers will help Green and Johnson complete their lineup of key machinery for their customers.

“The Apache lineup is a really good fit for us,” Green said. “We have offered harvest and tillage equipment, so adding these sprayers is something we needed. We’re excited to bring them on.”

Grauer Repair Service offers Oregon farmers the ‘simplistic elegance’ of Apache Sprayers

Family-owned Willamette Valley company becomes PNW region’s newest Apache Sprayers dealer.

Oregon’s Willamette Valley is world-renowned for Pinot Noir made from its more than 19,000 acres of vineyards in the area stretching from Portland to Eugene. The area is rich in agriculture beyond wine grapes with high volumes of filberts and grass crops — that means big business and high demand for ag sprayers as grasses require multiple passes through the field.

Grauer Repair Service in Sheridan, Oregon, is the newest Apache and Bruin Sprayers dealer in the Pacific Northwest, focusing primarily on supporting the region’s farmers working in the grass seed sector.

“Sprayers are running nine months out of the year here, mainly applying fungicides and growth regulators,” said Grauer Repair Service machinery sales and maintenance manager, Fraser Holmes. “We also fertilize at least twice a year, with different fertilizer products applied depending on the time of year.”

A family business

Grauer Repair Service is a family business started by longtime machinery service technician Dennis Grauer in 1987. Today, Grauer’s son, Travis, owns the company that Holmes describes as a “local, small customer-focused dealership.”

“We run hard. There are only seven of us, but our biggest advantage and something we prioritize is service,” Holmes said. “It’s a big buzzword around the industry, but for us, it’s not. It’s just how we operate.”

That was one of the reasons Grauer Repair Service initially gravitated toward Equipment Technologies (ET) as a company partner. Holmes saw the same commitment to service in the ET team that he and the Grauer family emphasize in how they serve their customers. The other reason: Apache Sprayers embody a few key characteristics Holmes said are important to their customers.

“The biggest thing our customers appreciate most about Apache Sprayers is their light weight. That’s huge for producers in this area. You can put bigger tires on an Apache and you won’t get bogged down and cause compaction,” Holmes explained. “Apache Sprayers are the lightest on the market by far, and that makes them a big win for our customers.”

‘Simplistic elegance’

Apache Sprayers also feature straightforward, simple controls which makes the machines a good fit for local farmers. Holmes expects as Grauer Repair Service introduces more customers to Apache Sprayers, they will embrace the machines’ features just as he has.

“If you purchase a competitor’s machine, there are so many controls and buttons in the cab that you’re never going to use in your life. An Apache Sprayer is simple, user-friendly and grower-oriented. They just have a simplistic elegance to them,” Holmes said. “We’re optimistic our customers will be drawn to those features as well.”

Unique Spraying Challenges in 2019

How to overcome unique spraying challenges.

So, you planted late. Now what?

Whether you planted late due to the weather or didn’t get your crops all in the ground at all this spring, you’re likely going to face some unique weed control and spraying challenges as your crops race toward maturation and the highest potential yield.

If you were able to get your crop planted — or most of them — some acres were likely not sown during the optimal planting window. If that was the case, your weed control strategies may need to change as your crops mature, according to University of Nebraska Extension Weed Management Educator Chris Procter.

When using any herbicide containing atrazine, for example, you can only apply that product when the corn is 12 inches tall or shorter. Applying later than that could mean significant crop damage. Glyphosate can be applied to corn up to 30 inches tall. Post-emergence herbicide applications like these are effective. But they require different management than those earlier in the season, a timeframe that may have closed before many late-planting farmers were able to get into the field to spray, thus causing spraying challenges.

“Even the best weed management plans sometimes fail due to circumstances outside our control. Weeds like marestail, waterhemp and Palmer amaranth can be particularly difficult to control mid-season. For each of these weeds, an aggressive strategy to manage escaped weeds is critical. If the area of escaped weeds is relatively small, a target herbicide application or hand rogueing is the best option to prevent the weeds from infesting a much larger area the following year,” Procter said in a university report. “Extra effort in year one when the problem is relatively small will save a lot of time and money in subsequent years.”

In addition to managing weed escapes later on in the growing season, each product’s residual effect must be accounted for as it relates to both your neighbor and your specific crop rotation, and the possibility you could be causing problems for next year.

“When making postemergence herbicide applications, crop safety is an important consideration as is the potential for off-target injury to a neighboring field,” Procter said. “When making in-season applications, consider crop rotation restrictions as fall cover crops or spring rotational crops may be affected, depending on the herbicide selected.”

Late to the field? Fine-tune your herbicide applications with our experts tips.

Didn’t get to plant at all?

What if you had to file Prevented Planting (PP) claims with the U.S. Department of Agriculture Risk Management Agency (USDA-RMA)? You may not have a crop in the ground in some of your fields, but that doesn’t mean you can forget about weed control this year. Winter or summer annuals allowed to produce seeds will only complicate weed control next year if left untreated, leading to even more spraying challenges, according to University of Illinois Extension Plant Protection and Weed Science Specialist Aaron Hager.

“Any weed seed produced in 2019 will add to future weed control costs. The old weed science adage ‘One year’s seedling equals seven years weeding’ reinforces the need to adequately manage weeds on prevented planting acres,” Hager said in a university report. “Many species of winter annual weeds already have flowered and soon will produce seed. Additionally, many summer annual weed species have emerged and are growing rapidly. We suggest the focus of weed management on prevented planting acres should be on summer annual weed species. Several options exist that could be used singly or in combination to keep weeds under control.”

There are a number of options for knocking down weeds in a field where you’ve filed a PP claim. Tillage and mowing are historically popular options but less effective when soils are wet, or weeds are larger. Cover crops can help limit the growth of any summer annual weeds but require tillage or an early herbicide application prior to planting.
