Top 10 tyre tips for harvest
Michelin’s Customer Engineering Support Manager, Gordon Brookes is urging farmers to prepare for a smooth-running 2019 harvest and shares his top 10 tips for effective tyre and wheel management.
“Time, weather and crop constraints make it essential that machinery is ready for use and leaving checks until the last minute can result in unexpected machine downtime,”
explains Brookes, who has 32 years’ experience at Michelin under his belt.
MICHELIN’S 10 TOP TIPS FOR TYRE SET-UP DURING HARVEST SEASON
During previous harvests tyres may have suffered accidental damage, leaving them with bulges, cuts or tears. Checking the tread area and sidewalls right down to the wheel rim now guarantees that any problems can be detected as soon as possible. Leaving damage unchecked can result in costly tyre failure and harvest interruptions.2. Check for flat spots
Long periods of inactivity can leave tyres with a ‘flat spot’ due to one section of the casing being deflected, creating massive vibrations on the road. To combat this, mark the affected area of the tyres, move the combine into direct sunlight with other sections of the tyres deflected. If possible – inflate the tyres above your standard operating pressure and leave them for a couple of hours, whilst ensuring the manufacturer’s maximum inflation pressure is not exceeded. Warming the tyres in the sunlight will prompt the casing to return to its normal shape.3. Check your tyre pressures
Ensure that tyres are inflated to the correct pressure in readiness for harvest, considering maximum cyclic load in the field and whether the combine will be used on side slopes or intensively on the roads.
If you need new tyres, or a new machine, take tyre choice seriously. Tyre choice can make the difference between a good harvest and a great one and for most combines and foragers there is now a tyre that contains Ultraflex technology, which limits soil compaction and disturbance on headlands whilst offering greater operator comfort, manoeuvrability and load capacity.
5. Transport width
Is your combine too wide for the road or gateways and would a narrower tyre speed up the harvesting process? If so, there are now tyres for combines that are narrower but have a greater contact with the ground. For example, a Michelin 900/60 R32 conventional tyre assembly could be replaced by a Michelin IF 800/70 R32 assembly, giving a 15 per cent larger footprint whilst making the combine 200mm narrower.6. Rear tyres
Rear tyres can affect the efficiency of the combine but are more commonly neglected. Farmers often don’t always realise that many of these tyres are designed for industrial machinery and require very high pressures which can cause damage on headlands. It’s therefore important to allocate the same time specifying rear tyres as you would the front set.7. Regular tyre inspections
Daily tyre inspections can often be overlooked but are essential in prolonging tyre life and machine availability. Spotting cuts and tears as they appear helps ensure they can be repaired in a timely manner and limits machine downtime.8. Watch those wheels
To prolong tyre life, wheels need to be kept in tip-top condition too. Kerbing or hitting a pothole can affect a machine’s wheel alignment, leading to rapid and uneven wear on the rubber.9. Putting the brakes on
It’s common sense advice that accelerating slowly and braking progressively maximises tyre life. Easing off the brakes and making a conscious effort to accelerate gently can pay dividends in keeping rubber in service for longer.
Make sure that all machinery involved in the harvest is in excellent condition and tyres inflated to the correct pressure, not just the harvester itself. Consider grain carting as an example – is the road work intensive? If so, the tractor and trailer tyres need to be inflated accordingly to reflect this intensive operation.
