Pottinger Torro Combiline.
Grassland, cultivation and seeding specialist Pottinger has updated its guide to tyre choice and use for agricultural implements, including its own balers and forage wagons.
This shows the effect of tyre size and inflation pressure on resultant ground pressure and hence the extent to which the soil may be damaged, a spokesman says.
“For the maintenance of soil fertility and performance, vehicle weight must be kept as low as possible and the largest-possible tyres (diameter-wise) are shown for each model.” Of course, this helps distribute the load evenly, while the larger ‘contact patch’ helps retain soil structure.
For example, on a Pottinger Torro Combiline with an axle load of 10 tonnes and fitted with 800/45 R26.5 tyres inflated to 1.6 bar for road use, the resultant ground pressure in the paddock would be 1.66kg/cm². When shod with smaller 710/45 R22.5 tyres, these figures increase to 2.6 bar pressure on the road and 2.2kg/cm² in the paddock.
Drawing on data provided by the Southwest Falia Agricultural College in Soest, Germany, the company also notes that creating a 1cm-deep wheel-mark in the paddock can consume up to 10% more diesel, due to the increased rolling resistance.
Pottinger claims compaction damage can even result in fertiliser costs rising by up to 20%.
Other benefits include a smoother ride for the operator and the machine, with the latter suffering less strain and metal fatigue when optioned with the correct tyres inflated to the ideal pressure.
The manufacturer warns that for safety reasons the tyres should not be over-sized, as this might adversely affect the efficiency of the brakes and handling while cornering.
Well known for its innovative seeding solutions, Pöttinger’s new Aerosem M implement-mounted pneumatic seed drill offers a precision metering and rugged coulter system for exact seed placement and prompt and uniform emergence.
Austrian manufacturer Pöttinger gave a sneak peek of a new automatic swath placement system for the Novacat V 10000 ED/RC Collector mowers at Agritechnica 2025, and recently confirmed that the upgrade will be available for the upcoming European mowing season.
Austrian manufacturer Pöttinger previously focused on grassland equipment then entered the arable sector with its acquisition of “Bayerische Pflugfabrik Landsberg”- the Bavarian plough factory - in 1975.
Pottinger has released details of its newly developed LIQUIDO F front-mounted, multi-purpose silage additive tank.
Formed in 1871, Austrian agricultural machinery manufacturer Pottinger originally focused on producing grassland machinery for a little over a century.
New Zealand dairy farmers are set to be the first in the world to receive access to a new digital physical milk pricing tool that enables them to fix the price for their physical milk.
State farmer Pāmu is opening its farm gates this summer in an effort to give the rural sector the opportunity to see how large-scale, multi-system farming is delivering productivity and profitability across New Zealand.
A five-year study has found that the cost of reducing emissions without technology may be significant and unsustainable for Northland dairy farmers.
DairyNZ says Waikato farmers need certainty on Plan Change 1, but they say that certainty must be matched with practical, workable rules and a clear transition that doesn't get ahead of the new resource management system currently under review.
While the Government has moved quickly to make commercial hauliers' lot easier during the current fuel crisis, they appear to be stuck in the creep box when it comes to the agricultural industry.
Waikato farmers have been told that the Government’s new planning system legislation and the region’s Plan Change 1 (PC1) “won’t mesh together very well”.
OPINION: No one messes around with Winston Peters, more so in a general election year.
OPINION: Staying on Federated Farmers, this week's annual general meeting in Auckland is shaping up to be an interesting one.
