Side-to-side flexibility demonstrated by H500

Most producers view purchasing a seeding system as a long-term investment. The life requirement of these robust machines is four times longer than previous models. That is why the John Deere seeding group has built even more durability into the H500 and H500F Air Hoe Drills. 

An advanced and rigorous testing program has proven the machine durability to the extent that John Deere now offers a three-year frame warranty with each H500 and H500F that rolls out of the factory.

Robust ball joints

Cast rank tube connectors

Robust ball joints connect strong fore-aft tubes to 100-mm x 100-mm (4-in. x 4-in.) rank tubes, which are joined to one another by pivoting rank connectors. Both the mainframe and wing sections share this durable construction that enables the frame to flex diagonally, relieving stress on solid frame members and avoiding frame failures.

Seed smart with confidence that the H500 and H500F will endure the field conditions.

Seed depth uniformity

Diagonal frame flexibility keeps openers engaged

Producers are more attuned to the importance of seed depth than ever before. A uniform-looking field is not the only goal; yield is too. Proven yield penalties across the world range from 5 percent to 25 percent, depending on depth variance.

The H500 and H500F feature diagonal mainframes and wing flexing – helping openers maintain their depth over uneven terrain.

Setting depth is one of the most critical adjustments an operator will make to a seeding tool. John Deere understands every operator needs dependable, repeatable depth control that is easily adjustable. Not every producer agrees on how to make it. That is why John Deere provides a choice of two depth control options on the H500 and H500F.

Mechanical depth shims are repeatable and reliable

Adjusting mechanical depth shims

Often heard are comments from producers who say they prefer the positive mechanical depth control offered by the 1820. This popular concept is base equipment on the H500 and H500F air hoe drills. 

Two indexed depth shim packs on the mainframe are not only easy to set but reduce the number of adjustment sites over previous designs by up to 60 percent.

Less time adjusting means more time seeding.

TouchSet™ depth control

Changing field conditions such as moisture levels and soil types can make setting depth a challenge.  TouchSet depth control makes adjusting depth in response to changing field conditions easy and profitable. On 8R and 9R Series tractors, the operator uses selective control valve (SCV) #1 and the SCV TouchSet control panel to perform all the depth control functions from the seat. Considering yield penalties of 5 percent due to seeding 2.5 cm (1 in.) too deep or too shallow, the convenience of in-cab adjustment pays nicely.

NOTE: Repeatability is +/- 6 mm (0.25 in.) to preset depth. If your seeding operation requires accuracy greater than +/- 6 mm (0.25 in.), the use of shim packs is recommended.

Control arm

CommandCenter™

How does it work? The operator uses the TouchSet (SCV setup panel) to set or change the operator depth.

• With the implement nine-pin connector connected to the tractor, start the tractor; a P will appear in the window of the control panel under SCV #1.
• The remote sensor located on the rockshaft monitors position of the implement.
• After operating depth is measured at the ground engaging tool and the desired depth obtained, press the lower set button on the control panel. That depth is now set.
• On-the-go depth changes can be made by touching the set button to select a new depth.
• Implement raise height selection uses the upper set button on the control panel to preset the distance the implement is raised above the operating depth.

Preset the raise height to:

• Take out wheel tracks on headlands
• Limit raise height for waterway crossings
• Manual depth override capacity

Remote position sensor

Electrical connector

A remote position sensor (1) is located at the rear of the drill; electronically monitors the positions of the implement.

An electrical connector is used for easy hookup of TouchSet depth control sensor on the implement to the tractor system (8R Tractor illustrated).

NOTES:

1. For use with all 8R and 9R (or older models) Series John Deere tractors.
2. TouchSet depth control requires additional tractor parts for hookup; see appropriate tractor section in this Sales Manual.

TruPosition 250-kg (550-lb) trip force

250-kg (550-lb) trip-force TruPosition standard

Unmoved

That is how John Deere’s TruPosition standard may be described. When the seed depth consistency and row spacing integrity are top concerns, this low-maintenance design will not compromise.

This can translate to a more than 5 percent yield increase by maintaining seed depth in tough ground conditions. The no-bolt design means avoiding maintenance costs and damaging downtime down the road.

It has a 51-degree shank.

Harrow

Seed depth consistency is a function of initial seed placement below the soil surface and displacement of soil over the seed row. When soil throw from the openers is great enough to cover up neighboring seed rows, a harrow is recommended to level the seedbed and equalize displaced soil over all seed rows prior to packing.

H500 with sweeps, harrow, and 14-cm (5.5-in.) packers

Equipping an H500 with the optional two-bar harrow helps level the seedbed before packing, ensuring an even distribution of soil over all seed rows. Adjustments include both vertical and tine-pitch, allowing the operator to set the harrow for the level of aggressiveness needed to level the seedbed.

NOTE: Not recommended for seeding into surface residue levels exceeding 35 percent.

NOTE: Harrow is not compatible with H500F.
