CLAAS expands DISCO mower line-up

CLAAS has announced the addition of six new side-mounted models to its DISCO mower series that will complement the existing range of front-mounted, rear-mounted and trailed models.

CLAAS’ DISCO range now spans over 30 models with widths from 2.2m up to 10.7m.

DISCO 10 range

The new models include the entry-level DISCO 24, 28 and 32 models, with working widths from 2.2 to 3.0 m.

“These three DISCO 10 mowers feature professional technology found on larger units, including the MAX CUT cutterbar and a double gearbox,” said CLAAS Harvest Centre Product Specialist, Blair McAlwee.

“As is the case with previous models, the power flow is directly fed into the inner mowing disc from above, which means that no inner shoe is required and efficiency is increased.”

“The powerful belt drive can be tensioned without tools using a rotary knob.

“The PTO shaft speed can be reduced from 540 to 480 rpm in light crops or when topping, which significantly reduces fuel consumption.”

MAX Cutterbar

The new models incorporate the MAX CUT cutterbar which features a wave-shaped mower bed press-formed from a single piece of material.

“This unique design has become synonymous with cutting quality, operational efficiency and reliability,” McAlwee said.

“MAX CUT combines the benefits of both the inline and satellite cutterbars.

“The cutting disc is positioned further forward on the cutterbar, ensuring the largest possible overlap between each disc for optimal cutting quality under all conditions.

“In addition, the SAFETY LINK module drive is connected to two drive gears, engaging with several teeth at each drive gear for maximum security, reliability and quiet, efficient operation.”

The MAX CUT mower bed is equipped with the SAFETY LINK safety module as standard and quick blade-change system.

“In the event of a collision, the module shears at a pre-determined breaking point but the cutting disc is held in the module by an axial bolt and cannot fly off,” McAlwee said.

“The safety module can be replaced easily and quickly.”

Max efficiency

The new side-mounted models feature a centre-of-gravity hitching for uniform contact pressure over the entire working width, similar to centre-mounted mowers.

“The line of force of the suspension spring runs exactly through the centre of gravity of the mower unit,” McAlwee said.

“These units can angle up to 45 degrees upwards and 20 degrees downwards.”

A mechanical break-out mechanism immediately responds to collisions and releases the mower bed to the rear and then automatically re-engages when reset.

The wide opening of the protective covers allows easy access to the entire working width of the mower bed for easy blade changing and maintenance.

The unit folds to a very narrow transport position of 95 degrees.

There are various mounting options available with the new DISCO 10 mowers, including the Quickhitch mounting frame and the lower attachment of the left-hand lower link pin designed for easy mounting to the tractor.

DISCO 100 series

The other three new models are part of the DISCO 100 series featuring working widths from 2.2 to 3.4 m.

“Again, these models have the new mechanical centre of gravity and suspension springs that are adjustable without tools,” McAlwee said.

“The new transport folding to 105 degrees ensures safe transport, even with lighter tractors.

“The field of vision of the tractor’s rear-view mirrors is not restricted by the mowing unit and the rear lights are not obscured.

“The new double-acting hydraulic ram ensures a reliable and safe folding process even on hilly ground and end position dampening.”

The new CLAAS DISCO mower models can be ordered from November 2020 onwards for delivery in spring 2021.
