407 409 AG HANDLING

Improved JCB compact wheel loaders being launched into the North American farm equipment market feature a new high performance engine - delivering excellent fuel efficiency and cleaner exhaust emissions without additional service or running cost burdens.

The new JCB 407 and 409 rigid arm compact wheel loaders are powered by the 2.5-liter JCB Diesel by Kohler 2504 TCR engine, which was jointly developed by JCB and Kohler engineers to meet stringent Tier 4 Final emissions legislation without the need for a bulky diesel particulate filter (DPF) or any other exhaust after-treatment.

JCB Agriculture Managing Director Richard Fox-Marrs said: “This gave our designers maximum flexibility when it came to meeting machine design and packaging requirements; as a consequence, the JCB 407 and 409 wheel loaders still have a low hood line and excellent rearward visibility.

“At the same time, the highly efficient engine also offers our compact wheel loader customers improved performance and lower fuel consumption, as well as the potential for reduced running costs thanks to low oil consumption and, subject to operating conditions, 500-750 hour oil filter intervals.”

The new 407 and 409 loaders are part of an expanding JCB Agricultural product range for loading and material handling duties on farms and ranches. They are quieter, have upgraded hydraulics and a more informative instrument display.

But the new engine is at the heart of these machines and operators are in for a treat as far as performance is concerned.

At 64 hp, the JCB 407 (which replaces the current 406) gains more than 4% peak power output over the air-cooled engine used before. And although engine power for the JCB 409 is unchanged at 74 hp, increased torque output makes a real difference – up 20% on the 409 and up 58% for the 407. Moreover, peak torque is generated at 1500 rpm, down from 1700 rpm.

Just as impressive is the amount of torque available when the engine is worked hard – at just 1000 rpm, there is still almost 90% of peak torque on hand to help push a fork into a manure heap, slide a bucket into a bulk feed stockpile, or push a scraper full of slurry into a storage pit.

This generous torque output also means the operator can do much of his work at lower revs – so there is great potential for working more quietly and with greater fuel economy, especially thanks to the JCB Diesel by Kohler engine’s precise fuel metering and delivery achieved by an advanced high pressure common rail injection system with electronic control.

Handling performance is already competitive so remains unchanged. The 407 is rated with a payload of 3,637 lb (1650 kg) while the 409 is rated at 4,314 lb (1957 kg); both have a load-over height of 10 ft 2 in (3.1 m) with a 1.05 cu yd (0.8 cu m) and 1.2 cu yd (0.9 cu m) bucket, respectively.

But the hydraulics system has been uprated with increased flow on both machines of

16.9 gallons/min on the 407 and 23.5 gallons/min on the 409, with a new high flow pump option adding 7.9 gallons/min in each case to handle a wider range of attachments, implements and specialty tools.

Both machines can now be fitted with a 100% locking differential in the front axle for maximum grip when ground conditions are especially difficult.
