Single cylinder depth control guarantees more accurate seed placement than series cylinders commonly used by competitors. This is achieved by eliminating the leakage that occurs between hydraulic cylinders in series, which constantly need rephasing. The result is dependable accuracy in the field – where it counts.
To ensure the seeding depth doesn’t change while working, Ezee-On uses positive mechanical depth stops that clip onto the single depth-control cylinder, conveniently located at the front of the machine. With cylinder adjustments in 1/8” (3mm) increments, operators are able to set the Air Drill for precise seeding results every time.
Ezee-On places all front caster wheels inside the first row of the Drill’s frame. This enables the Air Drill to follow uneven ground very accurately because it shortens the contour depth. Large 11L and 12.5L tires are standard in order to offer maximum floatation. (see Specification Chart)
Producers demand flexibility in the field. Ezee-On has perfected a flex-wing hinge system that gives the fore/aft travel needed to follow the ground and reduce torsional stress without any maintenance required. The fixed hinge on the second row of each section provides weight transfer from frame to frame to ensure proper depth penetration from each section.
 
Packer wheels are sometimes required to roll over rocks, stumps, etc in the field. Ezee-On’s walking beam design provides positive packing pressure by allowing individual gangs to roll over obstructions without affecting its adjacent gang.
Front-to-rear leveling on a Series II Drill is simple as 1.2.3.
1. Remove quick-pin.
2. Extend or contract pusharm by turning clockwise or counter clockwise.
3. Reinstall quick pin. Note: extending the pusharm will raise and contracting will lower the rear of the Air Drill.
Side to side wing leveling is also simple as 1.2.3.
1. Loosen jam nut.
2. Extend or contract quick wing leveler by turning shaft.
3. Tighten jam nut. Note: extending will raise and contracting will lower the side of the wing.
Moving trash residue through the frame without plugging can be challenging for competitive 4-row frame Air Drills. 7550 Series II Drills have a fully welded 5-row frame design that ensures no two shanks are placed closely on the same row, or front to back, leaving smooth field finish.
 
The heart of Ezee-On’s rugged spring cushion shank is the 3.5” (89mm) full width nylon-graphite bushing. Self lubricating, these bushings have a long service life with no maintenance required. Shank assemblies, (pre-assembled at the factory), have dual springs with a choice of 350 lb (159kg) or 550 lb (250kg) initial breakout force.
Whatever your soil type or opener style, Ezee-On has a packer wheel that will be a perfect match. Semi-pneumatic rubber will flex and shed wet, sticky soil. Ezee-On’s steel packers, with industry leading ¼” (6mm) face, are better suited to rocky conditions.
Underframe clearance is an important part of any Air Drill’s performance. Ezee-On offers 35” (889mm) of opener to frame clearance allowing trash to flow through the Drill with ease. 46” (1.2m) of clearance is achieved when the Drill is lifted completely.
In transport, both front casters and rear transport wheels are automatically locked with Ezee-On’s over-center, mechanical linkages. Hydraulic pressure unlocks the Drill from the transport position.
 

Located at the front of the drill, these lock-out valves ensure safer transportation. Should the operator accidentally move a hydraulic lever, the wings will not unfold and the Drill will not lower when these valves are in the locked position.

 
For producers looking for the ultimate in quick and easy maintenance, Ezee-On offers central grease banks located at the front of the Air Drill. High pressure grease hose leads to each rockshaft bearing located in the middle of the frame. Available in 2007.
For producers wanting to single shoot, Ezee-On offers four seed boot choices with varying spread patterns. A wide variety of aftermarket double shoot openers are available from your dealer to fit Ezee-On Air Drills.
 
Ezee-On’s optional 2-row in-frame harrows provide a more level field finish and better seed-to-soil contact. Operators can adjust the angle and down pressure of the 16” (406mm) tines to match varying field conditions.
Note: Requires changing shank configuration from 5 rows to 4 rows.
Economical End Shank Gauges provide visual indication of the Drill’s field position and can help prevent costly overlaps. They are fully adjustable and offer spring breakaway protection against impact. Available on all Ezee-On Drills except 28’ (8.5m).
To increase floatation, mainframe dual caster wheels are standard equipment on 40’ (12.2m) and larger Drills, and optional on all smaller 3-section Drills. Furthermore, the smallest tire Ezee-On supplies on the 7550 is an 11L, most competitors use smaller 9.5L tires.
Rock deflectors are available to prevent rocks or stumps from lodging between packer wheels. Steel packers have adjustable, hardened mud scrapers available to strip off mud and ensure consistent packer performance.
