Irish farm equipment manufacturer McHale has revamped its V660 and V640 variable chamber round balers to give Australian farmers better productivity on farm.
According to local distributor PFG Australia, the new and improved balers from the V6 range have been designed to produce denser bales at higher speeds, thanks to increased rotor sizes, larger crop augers and a new flexible floor design.
“The benefit to the farmer is more leaf product in each bale,” says PFG Australia’s Ian Young.
“As a result of the higher density achieved, each bale provides an even higher quality feed in consistently shaped bales.”
The rotor diameter has been increased by 40mm to allow a higher volume of crop intake. New large lateral augers further improve the flow of crop into the V660’s 15-blade chopper unit, or directly into the bale chamber of the V640 (non chopper model).
A new flexible floor adjusts itself to allow larger lumps of grass as well as increased crop intake to feed through to the chamber.
The bale chamber has three heavy-duty, reinforced endless belts to absorb and apply pressure to the material in the chamber.

The V6 series balers can produce bales with widths from 0.7m, adjustable by 20mm increments up to 1.68m.
McHale has also made several technical improvements to the V660 including adding a new density valve and ultrasonic bale shape indicator (which detects the movement of the belt). McHale says these features, combined with several other new design elements, let the baler produce consistently dense, uniform cylindrical bales at higher speeds.
All new McHale V6 machines are fitted with a new hydraulic stretch netter. As crop or weather conditions change throughout the day, operators can easily adjust the net tension to suit without having to leave the cab.
A further improvement McHale made to the new models to prevent stoppages, even in heavy sticky crops, is the fitting of a cleaning auger, now standard on the V660 and as an option on the V640. Fitted to the secondary drive roller, the auger eliminates contamination in the bale chamber by reducing build up on the drive roller.
A newly designed bale kicker is fitted to all V6 machines for the coming season. This new design gently places the netted bale on the ground.
Both V660 and V640 balers are fully automated and easily controlled from within the tractor cab via the Expert Plus Control Console. From the screen, operators are able to control bale characteristics and be alerted to any issues that may arise during baling operations.
