Mower power from Mayo innovators

After a tough year which saw a factory fire damage the firm's Ballinrobe plant, it was good to see McHale bounce back at the National Ploughing Championships.

Two impressive machines were unveiled by the Mayo grass men, and both will be of big interest to contractors and farmers. The new models are a long-awaited front and rear silage mower combination, and a high output bale wrapper.


Let's look at the front mower first. McHale's team have designed the frame on their new Pro Glide front mower to place the centre of gravity as close as possible to the tractor. This results in excellent responsiveness to changes in ground conditions. The support frame responds to uneven terrain to glide over the ground through the use of an integrated suspension.

An integrated suspension allows the mowing unit to move completely independently from the front linkage. At standard settings the cutter bar has a remarkable 500mm adaptive range, which allows the mower to automatically adjust to ground contours.

When faced with an incline or decline in ground conditions the cutter bar automatically adjusts its mowing angle by inclining upwards over bumps and slanting downwards into a dip.

The Pro Glide tubular support frame is designed to maximise the cutter bars clearance for headland turns and when in transport.

When raised the mower has an impressive clearance of over 600mm between the bottom of the cutter bar and the ground (this will vary depending on tractor type and tyres) Stabiliser stops built into the tubular frame keep the mower centred during transport.

Rear mower

The McHale Pro Glide R3100 rear mowers comes standard with patented ground following technology, break-back protection, hydraulic ground pressure control and heavy duty bed design.

The cutter bar ground pressure can be set from the tractor cab and the working pressure is visually displayed on the clock mounted on the headstock. Once the desired pressure is selected the cutter bar working pressure can be isolated from the tractor hydraulics with a mechanical tap.

The gearbox powering the cutter bar is located behind the first mower disc, which allows the operator to mow into corners and over rough terrain without problems.

For transportation, the rear mower folds vertically to position itself behind the centre point of the tractor for safe transport. The transport height of the machine is reduced thanks to the positioning of the mower bed at a 110 degree angle.

McHale say this position allows for the centre of gravity to be close to the tractor, which ensures even weight distribution and stability during transport at high speeds on the road.

Cutter Bar

The 3m Pro Glide cutter bar is powered by a heavy duty right angle gearbox which is positioned behind the inner top hat.

A slanted leading edge of the cutter bar allows for clean forage separation and reduces ground contamination when working in lodged crops.

Large heavy duty spur gears take the PTO power and transfer it to the discs. Each individual disc is driven by a smaller spur gear.

The spur gears which drive the individual discs are mounted forward on the cutter bars which deliver maximum cutting performance even when working in lodged crops.

The mowing discs are specifically designed to maximise crop flow. Each mowing disc has its own individual protective safety mechanism. If a collision occurs, the mechanism will shear in order to protect the drive.

The knives orbit with a generous overlap, which ensures a clean cut, while feeding a smooth flow of cut material to the rear of the mower.

The McHale Pro Glide comes standard with a steel tine conditioner to help cut and condition the grass as efficiently as possible.

The position of the steel tines allow for powerful conditioning which ensures the mower can deliver fast uniform wilting leading to a neat swath. The conditioner is driven by a mechanical gearbox, and speeds can be adjusted between 700rpm and 1000rpm with the simple pull of a lever.
