8400 - 80'/88'/90' Side Fold

Key Benefits

One of the Largest Toolbars on the Market


Cover more acres with the Fast 8400 series. The 8400 offers a 90' toolbar so covering a large amount of acres in a short amount of time will not be a problem.







Wide-stance Parallel link


The wide-stance parallel linkage on all of our applicators creates three distinct advantages. It enables the toolbar to apply fertilizer without the bar "walking" when higher ground speeds are reached, it allows the bar to be raised and lowered evenly and the wide stance parallel links reduces stress on the center section. These features add up to better placement for your fertilizer investment.






High-crop Clearance

Every time you pull a piece of equipment through your field you risk crop damage, so Fast applicators are specifically designed to reduce crop damage with high-crop clearance of 21 1/2", and a wingkick feature that lifts the toolbar when turning on end rows.









Center-pull Hitch


Center-pull single tube hitches are another way Fast applicators are specifically designed to reduce crop damage, over wider double tube designs.








Short-coupled Trailers


Short-coupled trailers are another way Fast applicators are designed to reduce crop damage. Just as with our sprayers, the short-coupled trailer follows your tractor better than other designs, which results in less crop damage and greater yields.






Powder-coat Paint


When you make an investment in equipment, you want it to last, which is why Fast's equipment is all finished with baked-on powder coat paint. Powder coat paint gives equipment great resistance to harsh chemicals, which leads to a longer life and better resale value for you.






Tank/Cart Features

Patented “Stealth” Tank Design


Fast designed their patented tanks (patent # 7,585,000) to include a large troughed sloped sump with an additional drop down for maximum cleanout of product so you can be sure there is no product left in the tank for an extended amount of time. The low center of gravity on Fast's patented "Stealth" tank design allows for incredible axle adjustability. The tanks low profile design also allows for better rear vision than traditional tank styles. The 8400 series offers 1 tank size in in a 2400 gallon capacity. The Fast 8400 model also comes standard with a 10 gallon hand-wash tank.

Single Reach Tongue


The single reach tongue on all Fast applicators is specifically designed to reduce crop damage so the operator is able to have a sharper turning radius.








Tires/Dual Wheel Capability

IMG_8145_Small.JPGAt Fast we know every operator needs a piece of equipment to fit their operation. That is why we offer the option of allowing the customer to choose the axle that fits their row spacing. The 8400 series comes standard with a dual axle, and the standard tire included are the 380/90/46.






Hydraulic Pumps

The Ace 205-304F is the standard pump on all 8400 models. All pumps that are used on Fast equipment are field proven, durable and sure to have a long lasting life. Standard on all 8400 models is the pump hydraulic flow limiter that provides over-speed protection designed to give the pumps a longer lasting life.

Heavy Duty Jack


At Fast we understand the importance of a heavy duty jack that can be used with ease. That is why all Fast fertilizer applicators come standard with a 2 speed heavy duty jack stand with safe and easy hooking and unhooking to get you where you're supposed to be, in the field.






Toolbar Features

Hydraulic Fold Toolbars/Wing Kick


All Fast 8400 series is equipped with a 5"x7" double tube toolbar that is available in either 80' or 90' widths. At Fast we try our best to equip all our products with as much versatility as possible which is why we have designed all our 90' 8400 models to have an external hydraulic fold cylinder so the operator is able to fold the outer wing and have the ability to use the same toolbar at 60' as well. The 8400 models are designed to have a trademarked wing kick feature, when turning the wing will kick up so this will result in less crop damage. This long with our minimum 21.5" crop clearance helps prevent crop damage when turning on the ends.


Hydraulic Down Pressure on Wings


One of the most important features on an applicator is the ability to keep all coulters in the ground consistently with constant down force. This will allow for a much more consistent application, which will result in higher yields and a higher return on investment that will be evident in the fall. All Fast applicators are designed to have hydraulic down pressure on the wings which will give the coulters better ground penetration and much more consistent application.



Flex Hinge/Gauge Wheels


All Fast applicators are designed to have flex throughout the entire toolbar. This flex will allow for much better ground penetration and even depth control and fertilizer placement in uneven terrain. The 8400 series also has a flex hinge that Fast has incorporated. This allows for below-level travel on the toolbar, ensuring that the coulter is always in contact with the ground, giving you confidence that your nitrogen dollars are where you intended them to be. This hinge also allows for the unique side-fold transport position. The 8400 models come standard with four gauge wheels that help with a more consistent application throughout the entire toolbar.




Standard on all Fast fertilizer applicators is the heavy duty Clymer coulters. Clymer coulters are field proven, durable and sure to have a long lasting life, which is why Fast equips all their fertilizer applicators with the reliable Clymer coulter. Coulters can be installed at any spacing the operator prefers and can choose between an injector style or the coulter mounted knife.







Key Options

Key Options

 Larger or Single Dual TiresIMG_8145_Small.JPG

Help reduce soil compaction and increase flotation with larger diameter single tires such as 380/90R54 or upgrade to dual tires with 380/90R46 or 380/90R54 duals. Fast's "Stealth" tank and trailer design allows maximum flexibility with multiple dual spacing options from 62-120", 80-120", or 88-132". (Note that the 480/80R50 tires are standard with a 2400 gallon tank)





Iso Ready Connection

Ensure that your Fast applicator is fully integrated with your in-cab ISO display (such as a John Deere 2630 or CNH AFS Pro 700). This enables operators to have the ability to control application rate, section and swath control, mapping, monitor the amount of product left in your tank, ect. all through one display screen and also helps reduce in-cab clutter.


Tall Gauge Wheel

Increase the flotation of your Fast toolbar with 6.7x15 gauge wheels. These gauge wheels have a larger diameter and narrower width that the standard Fast gauge wheels which is also important in both narrow row applications and softer soil conditions.

Yetter Viper II Coulter


Upgrade from Fast's standard 20" Clymer coulter to a Yetter Viper II coulter. The wiper/gauge wheel design will help reduce the amount of soil that is thrown to help reduce crop disturbance. This coulter also helps provide more consistent fertilizer placement.








Hypro Cleanload Chemical Eductor

Add a Pentair Hypro chemical eductor with 5.5 gallon hopper and 316 stainless steel venturi. Makes it much easier to mix liquid fertilizer in an easy to access location. Tank rinse nozzle mounted in the 12” hinged lid provides aggressive hopper clean out. Also includes an in-hopper bottle rinse system for rinsing chemical containers onsite.



Tank Agitation

Add tank agitation to keep your liquid fertilizer adequately mixed in your main tank.

Why Side-Dress?


There has been a lot of discussion on nitrogen timing and the best methods to apply nitrogen. The University of Missouri states it well, “The BMP for timing of nitrogen (N) fertilizer applications is to apply fertilizer as close as possible to the period of rapid crop uptake (Figure 1). Managing N in this way will minimize losses of N from the field and will ensure adequate N availability to the crop during critical growth periods.”

 N_Chart.jpgIn addition, the University of Purdue states that ear size is first determined at V5-V6; “Kernel row number determination of the uppermost ear begins shortly after the ear shoot is initiated (V5 to V6) and is thought to be complete as early as V8.”

Therefore, we know that the primary goals of applying nitrogen is to apply it as close to when your crops need it as possible and also to apply it in a way that will minimize your risk of nitrogen loss to ensure nitrogen is in the soil, available for your crops when they need it.

First let’s take a look at nitrogen timing

  • If you apply all your nitrogen in the Fall you will have around 7 months from when you applied nitrogen to when your crops need it. This seems to be a big gamble and puts you at the mercy of weather to ensure that your nitrogen is still there and available in the Spring. If you get heavy rains in the Fall or Spring, you could lose a very significant portion of your nitrogen through leaching, which is also not as environmentally friendly since this nitrogen has nowhere to escape but deeper into the soil.
  • If you apply all of your nitrogen pre-plant you have cut down on some of your risk of nitrogen loss but you are still applying 1-2 months before your crops need it so there is still some unnecessary risk of nitrogen loss through leaching.
  • If you wait to apply a significant portion of your nitrogen until mid-summer right before the reproductive stage, you may not have all of you nitrogen needs met at V5-V6 when ear size is determined and you may have starved your crops during the early critical growth stages that give a baseline for future yield. In addition, what individuals pushing late-season side dress do not mention is that the microbes and organic matter in your soil contain a significant amount of nitrogen that is naturally released as the soil warms up through the summer.

Therefore, early sidedress strikes the perfect balance between applying your nitrogen just before it is needed by your crops and also ensuring that all of your crops nitrogen needs are met during the critical growth stages.

6.JPGNext, let’s take a look at nitrogen application methods, Dribble vs. Injection

The University of Purdue states that as much as 15-20% of surface applied urea-based nitrogen may volatilize (lost) within a week after application. They also stated that this risk is essentially zero if the product is injected into the soil.

If your nitrogen is applied on top of the soil you are relying on rain to take the nitrogen down to the roots where it is need for uptake. If we have a dry period in the summer, you are subjecting your nitrogen to significant risk of volatilization as it will convert into ammonia gas and escape into the atmosphere, never to be utilized in boosting the yield of your crops.

Injecting your nitrogen in the soil helps reduce this risk of volatilization and helps ensure that the nitrogen that you apply will still be there when your crops need it most.

Our crops are dependent enough upon timely rain, why would we also build this into our Nitrogen Program? Inject your N with a FAST Applicator and minimize this risk!

The University of Purdue sums it up best by stating “One of the keys to managing costs of nitrogen fertilizer or maximizing nitrogen use efficiency is to manage N sources wisely to minimize the risk of nitrogen loss due to leaching, denitrification, or volatilization. The use of a sidedress application strategy remains one of the easiest and least expensive ways to maximize nitrogen use efficiency.”

Invest in your operations with a FAST Applicator to maximize your nitrogen investment and yield by providing a boost of N just before ear size is determined and also minimizing your risk of N Loss by injecting your Nitrogen IN THE GROUND rather than taking an unnecessary risk and dribbling it on top.
