Combi-Lift Subsoiler

The HE-VA Combi-Lift sub-soiling unit

Add a HE-VA Combi-Lift Subsoiler to your Disc Roller and loosen the lower soil structure whilst incorporating and mixing surface residues in the same pass.

Reducing tillage costs is one of the key elements in keeping a profit showing on the bottom line. HE-VA have always looked hard at utilizing machines to a maximum so that several jobs can be done in one man/tractor pass. The bolt-on, hardened, points are quick to change and provide lift and cracking of the subsoil to open it up and ensure better plant rooting.

Two versions of the Combi-Lift are available, the mounted and the trailed versions. Designed with the same principles in mind the 3 and 3.5m working widths are available as mounted machines with shearbolt protection whilst the wider widths and longer hydraulic reset machines come as trailed units, Both types of Combi-lift can be fitted to customers existing Disc Rollers with the trailed versions available up to 5m in working width.

Two types of stone protection are available the hydraulic reset version allows the ability to cope with stony conditions on the move whilst the simple shearbolt unit provides manual protection.

All Combi-Lifts can be used at a working depth of up to 350mm (14”) enabling them to alleviate most types of soil pan and compaction whilst the Disc Roller cultivates the surface. Adjustment is either manual on the mounted machines with a pin and hole system or Hydraulic, from the tractor seat, on trailed models.

When the operator does not need to cultivate the soil surface then the Disc Roller discs can be lifted out of work hydraulically from the tractor seat effectively leaving the machine working as a subsoiler. Similarly the Combi-Lift can be lifted out of work if just surface cultivation is required.

With the 3 point linkage machine, where weight and size of tractor is important for lifting the implement there is also always the option to decouple the integrated Combi-Lift and Disc Roller and use the Disc Roller on its own on a smaller tractor for surface cultivation.

HE-VA Subsoiler Leg Design

Low draft and minimal down time

HE-VA subsoiler leg design means that the single piece winged hardox point lifts, cracks and fissures at depth without huge power requirement.

The standard point has a 200mm wide wing whilst a wider 350mm wing is available for different applications.

Bolt on points using a single bolt are quickly replaced keeping down time to a minimum.

As from 2009 the new cast point should approximately give you 30% better wear rates than the old Hardox point.

Available in 5 and 6 leg formats to suit 3m Disc Rollers or 6 and 7 leg formats to suit 3.5m Disc Rollers, the rigid shearbolt protected Combi-Lift is suitable for 150 to 275Hp tractors.

The heavy duty box section frame and cat III / IV linkage ensures there is strength in the machine to cope with the most arduous of conditions. Large under frame clearance and stagger of the subsoiling legs ensures that there is plenty of room for even the trashiest of crop residues to work through the machine. Besides the advantage of being able to split the two units to work either machine independently the fact the Combi-Lift and Disc Roller are connected by lower link hooks and a top
link means that the top link length can be adjusted to change the pitch of the tines and therefore adjust the heave from the points. This allows fine adjustment of the job in hand ensuring the best results.

Two widths of Combi-Lift are available to fit Hydraulic Folding Disc Rollers, a 4m with 7 tines and a 5m with 9 tines, these will suit tractors from 250Hp to 450Hp.

Available as Hydraulic Reset or Shearbolt protected units the Hydraulic Folding Combi-Lifts all have front depth wheels fitted as standard to prevent the machine being damaged if tines on one side or the other go in deeper on uneven soil. The tine holders are mounted onto the frame by clamps which enables tines to be dropped out of the frame and spacing to be altered within the limitations of the frame. Similar under frame clearance to the mounted units and increased stagger of 420mm along the row of tines allows even better trash clearance. A significant benefit of the trailed machine is that the tine depth is hydraulically adjustable from the tractor seat. Furthermore the Combi-Lift can be folded and locked in the folded position to allow the Disc Roller to be used on its own if necessary and as with the other machines in the range the Disc Roller discs can be retracted from work to allow the combination to be used as a subsoiler.

Only available as a trailed unit the Hydraulic Reset Combi-Lift is designed to fit 3m, 3.5m 4m, and 5m Disc Rollers.

It incorporates two Hydraulic Accumulators (See below) and a pressure gauge to allow the operator to set the pressure on the legs dependant on working depth. The Hydraulic Reset system allows legs to trip back when they hit an obstacle and then reset automatically on the move once the obstacle has been cleared.
