Oil bath tapered roller bearings minimize maintenance
Oil bath tapered roller bearings, sealed with industrial-grade seals, keep maintenance to a minimum and profitable working hours at a maximum. The bearings come complete with a wear plate.
-
Transport locks secure disk wings
Transport locks are standard, ensuring disk wings are in secure transport mode.
-
Disk blades (notched or smooth) available in two sizes
Disk blades are available in 66-cm or 71-cm (26-in. or 28-in.) diameters. Disk blades are available in smooth blades, notched blades, or a combination of front notched blades and rear smooth blades to meet a variety of needs.
For superior penetration in tough soil conditions, weight per blade ranges from 108.9 kg to 154.7 kg (240 lb to 341 lb) depending on the offset disk series and model.
-
Rear hitch for attaching an additional implement
A rear hitch is available for operators wanting to pull an additional implement such as a harrow or drag.
-
Clevis hitch is durable for those tough working conditions
The clevis hitch has a durable design and is designed for ease of use, long life, and tough working conditions.
-
End washers and wrenches keep gang shaft end nut tight
End washers help keep the gang shaft end nut tightened during operation, increasing gang wear life.
Two gang nut wrenches are supplied with each unit and securely attached to the unit, ready to use when the gangs need tightening.
-
Adjustable disk blade scrapers increase productivity
Adjustable disk blade scrapers keep disk blades clean and performing in wet and sticky soils for increased productivity.
-
Two separate control arms create consistent performance
Two separate control arms are standard, one for transport leveling and one for leveling while the disk is in the ground. Once set for a given soil condition, the disk will continue to perform with consistency.
