2018 Hay King Series VII Flex Narrow 7251-520 Cushion Flex

The Miller Series VII Tandem is designed and built for the heavy discing jobs. The standard models weigh from 600 to 680 Ibs. per foot of cutting width. The Series VII Model line uses 6" x 6" and 4" x 6" heavy wall tubing in the frame and two or three 3- 1/2" x 3-1/2" section tubes, depending on model and option. All bearing and spacing spools are heavy welded steel construction for strength and toughness (no castings are used in the gang system of washers and spools). Gang shafts are high strength 1- 3/4" cold drawn steel. The gang bearings use a special Miller shielding system to protect the primary bearing seals for longer bearing life. The front sections have bearings mounted outside the end blades to provide extra bearing strength and to provide a strong spacing spool backup to the two most heavily loaded blades of the machine. The gang sections are held to the frames with a large double-pin clamping system that has positive mechanical angle lock. The machine is heavily braced in the corners and critical load areas.

The Miller Series VII Tandem was designed in a compact, rugged frame styling which allows for increased strength. This design avoids the performance problems created by offset main frame wheels in the double-offset styling which causes the machine to roll sideways when leveled from front to rear. It also avoids the frame strength loss realized by the longer frames required for operating room in that type styling.

All wheels are dual wheels which have capability for side to side leveling control. Wing frames on flex units are designed for solid performance in operation, with extra strength to remain stable in difficult conditions.

All front section disc blades are of the same diameter to provide full depth of cut on the full cutting width of the machine, as the Miller Tandems do not require smallerend blades on the front sections to provide level discing performance. Series VII machines are available with 24" or 26" diameter blades, plain or notched, in thicknesses up to 5/16. Blade spacing on 24" blades is 9" front and 10 1/2" rear. Blade spacing on 26" blades is 10 front and 12" rear. The front spacing is closer for a better cutting action while the rear spacing is wider to give these blades more room to handle the loose soil and residues and to provide an easier, more complete soil aeration and residue incorporation. The Miller system of using a deeper concavity on rear section blades provides the ground leveling, soil lifting and mixing action in a soil conditioning performance that other machines cannot provide.

Although the Series VII is designed for high performance heavy discing, the machine has unique soil leveling capabilities that provide a finishing type performance.

Miller Series VII Tandems are equipped with a patented hydraulic axle control cylinder control. This unit provides adjustable positive mechanical control of discing depth as well as mechanical wheel lockdown for transport.
