Why a Montag

Made in the USA





How long has Montag been in business?

Some of the designs in the Montag air system go back to the mid 80’s.  Montag Mfg, became incorporated in 2005 and began building the Auto Steer Cart.

Where have Montag units been sold?

Primarily throughout the corn belt but also as far south as Florida and north into Canada.

Can I buy direct?....Who is my closest dealer?

We are continually adding to our dealer base and you can find your closest dealer by clicking here or contacting us.  In areas where we do not have sufficient dealers we do sell direct.



How does the cart auto-steer?

The Cart has two hitches instead of one.  When the toolbar that it is mounted to begins to turn it pulls one arm forward and pushes the other arm back.  This causes a change at the rear axle, adjusting the angles of the rear spindles. 

How easy is it to back up a Montag cart?

Most farmers find it quite easy to back up, in some ways it is easier than a standard two wheel cart.  See a video here of a 9 ton cart being backed up behind a 36 row John Deere Planter.

How sharp will the cart turn?

The cart was originally designed to track behind an 8 row, 30”, 3-point toolbar without hitting the row units.  Click here to watch a video of a 12 row, 30” with optional NH-3 hitch.

What kind of implement can I pull a Montag behind?

We have hooked Montag carts behind a variety of planters, strip-till bars and tillage equipment designed for row crop application and are continually designing more hitch options to better fit our customers’ needs. 

Will the cart hit my implement when I turn?

When properly attached the Montag cart will not hit the implement.  However, it is possible to do so backing up or turning too sharply with track type tractors.

What is the minimum distance needed from the front of the tire to the back of the row units?

The minimum recommended distance is 5’. 

How will a Montag cart hook up to my implement?

Montag offers a universal hitch that works in most cases and in some cases a specifically designed hitch can be obtained from Montag.  For more information contact your Montag dealer or Montag Mfg direct.

How much weight does the cart add to the toolbar?

Montag has designed its carts to carry 100% of the tank weight directly above the axle.  The weight of the two hitches and any additional weight created by stopping, starting or hills should be considered.


What options are available with a cart?

Montag offers options in row spacing, tire sizes and tank capacities.  For questions please contact your local Montag dealer or Montag Mfg direct.



Does the Montag come with a controller?

Montag carts can be ordered with a controller or are compatible with your existing controller.

What controllers will interface with a Montag fertilizer unit?

The Montag system is operated with a PWM closed hydraulic valve.  Controllers capable of operating a PWM closed valve and capable of operating with dry fertilizer will run the Montag system.



How accurate is a Montag fertilizer unit?

A properly set up Montag unit will obtain +/- 4% row to row accuracy.

What makes a Montag fertilizer unit different than other fertilizer meters?

Montag’s fertilizer metering systems are made of non-magnetic 300 series food grade stainless steel or chemical resistant plastic.  All rows are individually mechanically metered for greater accuracy.  Higher capacity and lower hydraulic horse power requirements are obtained by Montag’s unique centrifugal accelerator chamber.

How durable is the Montag fertilizer unit?

Montag’s fertilizer metering systems are made of non-magnetic 300 series food grade stainless steel or chemical resistant plastic.  With proper care it is an investment that should last 15-20 years.

How much horsepower does a Montag fertilizer unit use?

1 to 1.5 horsepower per row. 

What hydraulics comes with a Montag fertilizer unit?

The hydraulic fan motor, PWM closed valve, the hydraulic auger drive motor and connecting hydraulic hose and fittings. The hydraulic hoses that run from the metering system to the tractor are not included. 

What kind of air hose is required for a Montag fertilizer unit?

We recommend Kenaflex 112 or its equivalent.  Other smooth ID hose can be used.  For charts showing the best way to route your air hose click here.

How long will the air hose last on a Montag fertilizer unit?

From 15,000 - 35,000 acres depending on the size of the applicator.  The sun light also breaks down the hose in time.  Depending on if you store the machine indoors or outdoors it should last between 4-10 years. 

What should my air pressure gauge read for normal operation?

Between 20-25” WC.

Can I reduce the number of rows on a Montag fertilizer unit?

Yes, row reducer covers are available.

What type of fertilizer can a Montag apply?

The Montag metering system operates with a metering screw for each row.  Products that will feed evenly into the metering mechanism will generally flow through the metering system.

What kind of a rate will a Montag apply?

The rate a Montag can apply is based on the speed, density and pounds of product.  You can see a more detailed capacity chart here.

Can I blend two fertilizers on the go in the field?

Yes, Montag offers a Twin Bin option in 8 and 12 row configurations.  However, you must have a VRT controller capable of running two products.

What is an Air Diffuser or Air Release?

An air diffuser / air release is a venting system designed to go at the end of the main transfer hose to exhaust a portion of the air between the knife and the transfer hose.

What diffuser options are available?

There are several diffuser options CLICK HERE to see a full listing.
