HE-VA Combi-Lift Subsoiler

The Combined Force - Introduction

Add a 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.

Now the Disc Roller can be used in conjunction with the Combi-Lift as a one-pass subsoiling and surface cultivation tool.



Two versions of the Combi-Lift are available, the mounted and the trailed versions. Designed with the same principles in mind the 2.5m, 3m and 3.5m working widths are available as mounted machines with shearbolt or spring reset protection, whilst the wider and longer machines come as trailed units with a choice of shearbolt or hydraulic reset protection.

Both types of Combi-lift Subsoilers can be fitted to customers existing Disc Rollers with the trailed versions available up to 4m in working width.

With or Without? - Introduction

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.

One unit or two? - Introduction

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.

Subsoiling Depth - Features

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.

Shearbolt leg protection - Features

Available as both mounted and trailed units the shearbolt Combi-Lift is designed to fit 2.5m, 3m, 3.5m and 4m Disc Rollers.


The shearbolt Combi-Lift ustilises a single shearbolt on each leg to prevent large objects causing damage to the machine.

Spring Reset - Features

Only available as a mounted unit the Spring Reset Combi-Lift is designed to fit 2.5m and 3m Disc Rollers.

The Dual Spring Reset system allows the legs to hit an obstacle and then spring back to place on the move once the obstacle has been cleared. The reversible Durox c shaped legs are design to ensure excellent mixing of the soil and crop residues.

Hydraulic Reset - Features

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

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

Points - Low draft and minimal down time - Features

HE-VA leg design on the Combi-Lift means that the single piece winged point lifts, cracks and fissures at depth without huge power requirement. The standard long life cast point has a 200mm wide wing.

Hardox points are available in narrower versions at 80mm and 120mm widths and wider versions at 300mm and 350mm to suit different applications.

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

The standard point has a 200mm wide wing.

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

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

Rigid Combi-Lift Subsoiler - Models

Available as a 4 leg machine to fit 2.5m disc roller, 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.

Trailed Combi-Lift Subsoiler - Models

Available as Hydraulic Reset or Shearbolt protected units, the trailed Combi-Lift Subsoilers all have an upgraded reinforced drawbar, whilst the 4m has front depth wheels fitted to prevent the machine being damaged by tines on one side or the other going 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.

Folding Combi-Lifts 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.

Disc Roller

The HE-VA Disc Roller is a result of ten years development and testing to find the ideal combination of disc angle and packer ring to give perfect incorporation, mixing and consolidation in one high-speed pass.
