KEENAN MechFiber 340


The MechFiber 340 sets new standards in ration mixing, offering a high degree of on-farm manoeuvrability. It has a similar ‘footprint’ to the 320 but with it’s deeper body and repositioned cross auger, delivers higher capacity.

Superior MechFiber mixing

This latest generation KEENAN mixing system uses six angled paddles rotating at just 7rpm. A new knife design and greater clearance at the ends of the paddle-arms allows material to move freely, to further improve mixing.

Increased Mixing Capacity

The increased capacity of the compact MechFiber 340 mixer is achieved by extending the body down into the chassis and lowering the discharge auger to make a wider, deeper mixer. Variable discharge heights can be achieved with the use of ‘raisers’ and wheel sizes.

Lower power, tongue and fuel requirements

Controlled chopping speed significantly reduces torque requirements. A typical power unit is a 90 HP tractor, resulting in a dramatic saving on overall fuel consumption compared with other mixers, despite the larger capacity.

Simple two-chain drive system

KEENAN’s simple two-chain drive system has an unbeatable track record of reliability. A primary drive chain and three sprockets transmit power to the auger and idler. A second sprocket powers the much larger paddle sprocket.

Automatic oiler

An automatic oiling system can be fitted and is operated by the hydraulic rams opening and closing the guillotine door. This delivers ‘pulses’ of oil to the drive chains, lubricating them to the optimum levels for safety and improved chain life.


Baleblend  Big Bale processing

The MechFiber 340 can be supplied with the latest Baleblend bale chopping technology. Big round or square bales of forage placed directly on the machine’s top cradle are chopped and incorporated into the ration in a matter of minutes.

We can customise our machines to your needs:

• Height and Width
• Heavy duty knives
• Rear feed out
• Elevator tray

Bales Processed in 90 Seconds

KEENAN MechFiber 350


The MechFiber 350 sets new standards in ration mixing, combining KEENAN’s unique MechFiber technology with high capacity. It will feed approximately 100 cows in a single load. This mixer is ideal for medium to large scale producers. With its higher auger, position feeding into high troughs or barriers is done with ease. It comes with or without Bale Blending technology. There are a variety of optional extras that can also be chosen.

Lower power, tongue and fuel requirements

A typical power unit to tow a loaded MechFiber 350 would be a 90 HP tractor. To drive the mixer, when loaded, requires approximately half this power delivering substantial savings in overall fuel consumption (and often size of tractor) compared with other mixers. Simple two-chain drive system

KEENAN’s simple two-chain drive system has an unbeatable track record of reliability. A primary drive chain and three sprockets transmit power to the auger and idler. A second sprocket powers the much larger paddle sprocket.

We can customise our machines to your needs:

• Higher auger ideal for high troughs
• Automatic oiler & 2 chain drive system
• Bale Handler option
• Full length auger for consistent feed-out
• Variable Feed Control & Feed-out height

KEENAN MechFiber 360


The MechFiber 360 has the ability to feed large numbers of livestock with a single load and it is capable of working under the toughest of conditions, feeding large volumes day-in-day-out.

Increased mixing capacity

The increased capacity of the MechFiber 360 mixer is achieved with a longer body and by extending it down into the chassis and lowering the discharge auger to make a wider and deeper mixer. Variable discharge heights can be achieved with the use of ‘raisers’ and wheel sizes.

Lower power, tongue and fuel requirements

Controlled chopping speed significantly reduces torque requirements. A typical power unit is a 110 HP tractor, resulting in a dramatic saving on overall fuel consumption compared with other mixers, despite the larger capacity.

Heavy duty chassis, steering axles and road-suspension

The MechFiber 360 comes fitted with either single axles, tandem bogie axles or for the utmost manoeuvrability, steering axles. The heavy duty chassis is designed to give the driver improved weight transference and improved stability when travelling at road speeds (Single axle reduces payload to 6,500 kg).

Baleblend Big Bale processing

The MechFiber 360 can be supplied with the latest Baleblend bale chopping technology. Big round or square bales of forage placed directly on the machine’s top cradle are chopped and incorporated into the ration in a matter of minutes.
