Harvest may still feel some distance away, but August is when good preparation begins.

Earth Sciences New Zealand confirmed in July 2026 that El Niño conditions had developed in the tropical Pacific. As the season progresses, New Zealand may experience more westerly airflow, unusually windy periods and greater temperature variability. El Niño is expected to strengthen further, with potentially significant effects later in 2026 and during the 2026–27 summer.

No seasonal outlook can predict conditions in an individual paddock. However, the possibility of a windier and more variable growing season gives farmers and harvesting contractors a good reason to prepare for uneven, tangled or lodged crops.

A header front that performs well in standing crop may require more attention when the crop is leaning, lying close to the ground or feeding unevenly. Inspecting the cutterbar, reel, crop lifters and feeding components now can reduce the risk of rushed repairs when the harvesting window opens.

Here are the main areas to check before the 2026–27 harvest.

Do not inspect only the most visible centre section. Pay particular attention to the ends, drive-head area and any location showing noticeably different wear.

When replacing components, confirm compatibility against the header model, serial-number range and existing cutting system. Similar-looking guards and sections are not automatically interchangeable.

NZ Agro Parts carries knife guards, knife sections, cutterbar assemblies, knife drive heads and hold-down components for selected harvesting platforms.

1. Begin with the Cutterbar

The cutterbar needs to produce a clean cut before the reel and draper system can move the crop effectively.

Lodged or tangled crop can place additional pressure on the cutting system because material may approach the knife at inconsistent angles. Blunt sections or damaged guards can increase pushing, bunching and uneven cutting.

Inspect the entire cutterbar for:

• Blunt, chipped or broken knife sections.
• Bent, cracked or badly worn knife guards.
• Excessive clearance between the knife and guards.
• Loose section bolts or rivets.
• Worn wear plates and guides.
• Damaged or poorly adjusted hold-down clips.
• Free movement and correct alignment of the knife assembly.

Do not inspect only the most visible centre section. Pay particular attention to the ends, drive-head area and any location showing noticeably different wear.

When replacing components, confirm compatibility against the header model, serial-number range and existing cutting system. Similar-looking guards and sections are not automatically interchangeable.

2. Inspect the Reel Before Adjusting It

The reel helps present the crop to the cutterbar and move cut material towards the feeding system. In lodged or uneven crops, its condition and adjustment become especially important.

Before changing reel height, fore-and-aft position or speed, inspect the mechanical components:

• Missing, cracked or permanently bent reel tines.
• Loose tine mounting hardware.
• Damaged bats or supports.
• Worn bushes and bearings.
• Movement in reel arms and pivots.
• Hydraulic leaks or damaged hoses.
• Inconsistent tine spacing.
• Signs that the reel has contacted the cutterbar.

A reel with several damaged tines may feed crop unevenly even when its settings appear correct.

Avoid automatically using the most aggressive reel setting. Excessive reel speed or poor positioning can increase shattering, wrap material around the reel or push crop ahead of the knife. Begin with the machine manufacturer’s recommendations and make small adjustments for crop conditions.

3. Decide Whether Crop Lifters Are Needed

Crop lifters are designed to help raise low or lodged crop so the cutterbar can collect it more effectively. They can be valuable in difficult conditions, but they should be treated as a crop-specific tool rather than a permanent solution for every paddock.

Before harvest:

1. Inspect existing lifters for bending, cracking and worn contact areas.
2. Check that mounting points and hardware are secure.
3. Confirm that the lifters are suitable for the cutting system.
4. Review the manufacturer’s installation and spacing guidance.
5. Carry spare lifters and mounting hardware where practical.

The correct arrangement depends on the crop, lodging direction, ground conditions and header design. Incorrect spacing or damaged lifters can create inconsistent feeding or increase the risk of ground contact.

When working in badly lodged crop, operators may also need to reconsider travel direction and approach the crop from the most effective angle. Make changes cautiously and follow the header manufacturer’s operating instructions.

4. Check Auger and Retractable Fingers

On fronts using an auger or retractable finger system, damaged fingers can interrupt crop movement after the cutterbar has done its job.

Look for:

• Missing or bent fingers.
• Cracked poly fingers.
• Worn finger holders.
• Loose mounting hardware.
• Irregular finger movement.
• Contact marks inside the auger.
• Damage caused by foreign material.

A single missing finger may appear minor in the workshop, but several damaged fingers across the feeding area can create bunching and uneven delivery.

NZ Agro Parts lists steel retractable fingers, poly retractable fingers and finger holders for selected MacDon, Case IH and New Holland applications.

5. Protect the Front When Cutting Low

Lodged crop often requires the operator to work closer to the ground. That increases the importance of skid shoes, wear surfaces and front protection.

Inspect:

• Poly skid shoes for thin or worn sections.
• Loose or missing skid hardware.
• Uneven wear that may indicate poor adjustment.
• Bent mounting brackets.
• Damage from stones or previous ground contact.
• Rock-protection components where fitted.

Replacing an inexpensive wear component before harvest may protect a much more costly part of the header later.

Ground conditions can vary substantially across a paddock. A setup that works in one area may require adjustment when moving into softer soil, wheel tracks or uneven ground.

6. Build a Model-Specific Harvest Spares Kit

A useful spares kit is not simply a box of assorted parts. It should be based on the exact fronts being operated.

For each header, record:

• Manufacturer and model.
• Front width.
• Serial number.
• Cutterbar system.
• Knife section and guard references.
• Reel tine type.
• Auger finger type.
• Hold-down configuration.
• Crop lifter type.
• Frequently used bolts and fasteners.

A practical kit may include:

• Knife sections.
• Common knife guards.
• Hold-down clips.
• Reel tines and mounting hardware.
• Retractable fingers and holders.
• Crop lifter hardware.
• Cutterbar bolts and nuts.
• Selected bearings or bushes.
• Skid-shoe hardware.

The purpose is not to carry every possible component. It is to cover the smaller, predictable failures that can otherwise stop harvesting while a replacement is located.

7. Complete a Controlled Pre-Season Test

After completing repairs, do not wait until the first harvest paddock to test the front.

Before operating, check that all guards are fitted, personnel are clear and manufacturer safety procedures have been followed.

Then:

• Move the knife by hand only where the manufacturer permits.
• Check for tight or binding points.
• Confirm that hardware is secure.
• Run the front initially at low speed.
• Listen for knocking, scraping or irregular vibration.
• Observe reel and finger movement.
• Check hydraulic connections for leaks.
• Stop and recheck recently replaced components.
• Verify adjustments and fastener torque using the correct manual.

A controlled test provides time to correct small problems without crop pressure, transport delays or customers waiting.

Preparation Protects More Than the Machine

New Zealand’s arable sector continues to face pressure from restrained commodity returns and rising operating costs. MPI expects arable export revenue to recover gradually from 2026–27, but global oversupply and subdued pricing remain important commercial challenges.

In that environment, reliability matters. Avoiding one preventable breakdown, reducing crop left behind or completing a paddock within a suitable weather window can be worth considerably more than the cost of replacing worn parts beforehand.

The goal is not to predict exactly what El Niño will deliver. It is to make sure the header front is prepared for a wider range of crop and weather conditions.

Brand names and original part numbers are used for reference and fitment identification. Always verify compatibility and follow the machinery manufacturer’s safety, installation and operating instructions.

When harvest arrives, every hour matters. A worn knife section, weak reel tine, damaged guard or loose hold-down clip may seem small in the workshop, but in the paddock it can quickly become lost time, uneven cutting, poor crop flow and unnecessary stress.

That is why winter is one of the most valuable times of the year for farmers, harvesting contractors and agricultural workshops. It gives you the opportunity to inspect, repair and prepare your header front before the pressure of harvest begins.

At NZ Agro Parts, we supply premium OEM-quality aftermarket harvesting parts designed to help New Zealand operators keep their machinery performing when it matters most. Whether you are running MacDon, John Deere, Case IH, New Holland, CLAAS, AGCO, Lexion or other harvesting platforms, the goal is the same: reduce downtime, protect performance and keep the crop moving.

New Zealand arable crops are commonly harvested using combine harvesters, also known as headers, and the timing of harvest depends heavily on crop and grain moisture conditions. Once that harvest window opens, operators do not want to be waiting on small wear parts that could have been checked months earlier.

Why Winter Maintenance Matters

Harvesting equipment works in some of the most demanding conditions on the farm. Dust, vibration, crop load, wet patches, lodged crop, stones and long operating hours all place pressure on the front.

A header front that is not properly maintained can lead to:

Poor cutting performance
Crop bunching or uneven feeding
Increased grain loss
Higher fuel use
Premature wear on surrounding components
Costly downtime during peak harvest

FAR has also highlighted that when conditions are less than ideal, correct combine setup can help reduce losses and prevent unnecessary breakdowns. That makes pre-season inspection more than just a workshop habit. It becomes part of protecting yield and profitability.

1. Inspect Knife Sections

Knife sections are one of the first areas to check. Worn or damaged sections can leave ragged cuts, increase drag and reduce feeding efficiency.

Look for:

Rounded or blunt cutting edges
Broken tips
Bent sections
Loose bolts or rivets
Uneven wear across the cutterbar

If sections are blunt or damaged, replacement before harvest is usually a smarter decision than waiting for them to fail in the paddock.

NZ Agro Parts supplies OEM-quality knife sections and cutterbar components designed for strong cutting performance across major header brands and platforms.

2. Check Knife Guards

Knife guards play a critical role in supporting the cutting action. Damaged or worn guards can affect crop flow and place extra strain on the knife.

Inspect for:

Bent points
Cracks
Excessive wear
Broken prongs
Stone damage
Poor knife alignment

A good knife section still needs a good guard to perform properly. Replacing worn guards before harvest helps maintain a cleaner cut and smoother operation.

NZ Agro Parts stocks a range of knife guards, including options to suit MacDon, Case IH, New Holland and other fronts

3. Review Hold-Down Clips

Hold-down clips are small but important. If the knife is not held correctly against the guards, cutting performance can suffer.

During inspection, check:

Clip tension
Wear marks
Missing hardware
Bent clips
Excessive knife movement

A worn hold-down clip may not look serious, but it can reduce cutting efficiency and contribute to vibration through the cutterbar. Replacing them as part of a winter service is a simple way to improve reliability.

4. Inspect Reel Tines and Fingers

The reel is responsible for presenting crop evenly into the cutterbar and feeding system. Worn, broken or weak reel tines can cause uneven feeding, missed crop and poor performance in challenging conditions.

Check each tine for:

Cracks
Missing fingers
Loss of flexibility
Bent mounting points
Uneven spacing
Damage from previous harvest conditions

For MacDon, Case IH and New Holland draper fronts, reel tine condition is especially important when working through heavy or uneven crop. NZ Agro Parts supplies heavy-duty flexible reel tine fingers and related reel parts to help keep crop feeding smoothly.

5. Check Auger Fingers and Holders

Auger fingers and finger holders help move crop efficiently through the front. If they are worn or damaged, feeding can become inconsistent.

Inspect for:

Missing fingers
Bent or broken fingers
Worn holders
Loose mounting points
Uneven crop movement

NZ Agro Parts carries poly retractable fingers, steel retractable fingers and finger holders for selected MacDon, Case IH and related platforms, making this another high-value product area to promote from this article.

6. Inspect Crop Lifters

Crop lifters become especially valuable when dealing with lodged, low or weather-affected crops. MPI has noted that parts of New Zealand may face increased wet harvest periods, particularly Southland and North Otago/South Canterbury, where machinery may need to handle flattened or difficult crops.

Before harvest, check crop lifters for:

Wear at the contact points
Bent arms
Loose hardware
Cracks
Missing components

If your operation regularly handles lodged crop, crop lifters should be part of the pre-season conversation.

7. Check Poly Skid Shoes and Wear Areas

Skid shoes and wear surfaces protect the header front when operating close to the ground. Over time, they wear down and reduce protection.

Inspect:

Poly skid shoes
Wear plates
Mounting bolts
Cracked or thin areas
Uneven wear patterns

Replacing worn skid shoes before harvest helps protect more expensive components and reduces the risk of avoidable damage.

8. Build a Pre-Season Parts Kit

One of the smartest moves a contractor or grower can make is building a small pre-season parts kit.

Consider keeping:

Knife sections
Knife guards
Hold-down clips
Reel tine fingers
Auger fingers
Common bolts and fasteners
Crop lifter spares
Skid shoe replacements

This is especially important for contractors covering multiple farms, where downtime does not just affect one paddock — it affects the whole schedule.
