V8940 - Variable Chamber Round Baler 

The McHale V8940 is a non-chopper variable chamber baler equipped with a high intake feed rotor to ensure even and efficient crop flow to the bale chamber. The McHale V8740 is driven by a primary drive system for optimum bale formation. Central grease blocks are fitted on the machine for greasing while oiling is controlled through the continuous oiling system. Net and bale density can be adjusted from the cab through the Expert Plus control console.  

Key features include: 

• New pickup with a choice of cam track or cam-less to choose from
• Larger lateral feed augers
• Larger rotor
• Adaptive intake 
• Selectable knives
• Drop floor unblocking system 
• Three heavy duty endless belts
• High performance netting system
• Automatic greasing (optional)
• New panels
• Expert Plus control console
• Bale kicker

McHale have developed various types of pick-ups. After extensive testing, McHale decided it would offer customers the choice of two pickup options depending on their conditions: 

Cam pickup 

•          As standard, a cam operated 2.1m high-intake galvanised pickup ensures excellent ground cleaning in all types of crop. The cam pickup runs on a cam track that is fitted with double raced cam bearings to stand up to the most testing of conditions.
•          All pickups across the McHale variable chamber baler range are fitted with five tine bars for optimal delivery of crop to the bale chamber. The 2.1 metre galvanised pickup will lift even the shortest of crop. A side inspection port allows the operator to quickly check and change the cam bearings. 

Camless pickup - Optional indent order only 

•          A 2.1m camless pickup is available as an option on all machines in the variable chamber baler range. Six tine bars are fitted to all McHale camless pickups to provide excellent ground cleaning and fast delivery of crop to the chamber. The new camless pickup has been designed for increased output and, with that in mind, the cam-track free pickup is more reliable, consists of less moving parts and is maintenance free. 

All McHale pickups come with a number of standard features that include: 

Heavy Duty Pickup 

All McHale pickups feature heavy-duty tine bar supports to ensure long service life. A vital part of the pickup is the tine; McHale has developed a pickup tine designed to lift even the shortest of crop. 

Efficient Crop Flow Delivery

The specially designed McHale pickup is positioned close to the rotor to improve delivery of the crop through the rotor to the bale chamber. Large diameter lateral feed augers help direct crop to the bale chamber, ensuring a consistent and even crop flow for producing high density bales. 

Adaptive Intake 

Over the course of a baling season, machines have to work with different volumes of crop. McHale has designed an adaptive intake which allows the intake area to automatically adjust for light and heavy crops. This avoids peak loads and results in higher daily throughput regardless of working conditions.

Non Chopper Twin Finger Rotor

All balers in the variable chamber baler range are fitted with the McHale drop floor unblocking system, a feature which operators have come to love for its simplicity of use and effective unblocking cycle. As baling conditions are not always ideal, uneven swaths can occur which can lead to blockages. The drop floor unblocking system means blockages can be fed through in three simple steps: 

Drop the Floor 

•          Should a blockage occur, the sound of the slip clutch alerts the operator, who can hydraulically lower the floor from the tractor cab. 

Re-engage the PTO 

•          This widens the feed channel and, on re-engaging the PTO, the blockage can be fed through. 

Reset the Floor 

•          The floor can then be reset to its original position and baling can resume.

The V8940 can produce bales from 0.60m to 1.90m

A heavy-duty drive system powers belt and bale rotation on all machines in the variable chamber baler range. 

On all McHale V8940 balers, a double drive system is fitted to ensure belt rotation and bale formation. 

All V8 variable chamber balers are equipped with three heavy-duty endless belts as standard. These strong belts exert a high pressure on the bale in order to form a dense bale in the chamber.

These belts are manufactured to the highest of standards using layers of synthetic and rubber material to form a durable endless belt with no joins. 

In more difficult conditions, such as wet heavy grass, if the primary drive slips slightly, the double drive will engage in order to aid belt and material rotation in the chamber. 

This double drive helps bale formation, as a constant pressure is kept on the chamber belts, resulting in the production of a solid and uniform bale even when dealing with a wet and heavy crop.

The McHale variable chamber baler range of balers are fitted with a continuous oiling system. Once the PTO is engaged, the continuous oiling system constantly lubricates the chains to ensure a long lifetime. 

The continuous oiling system on the baler is driven off the gearbox and delivers oil to the following chains: 

•          Chamber drive-side chains
•          Rotor – drive chain
•          Pickup – drive chains
•          Pickup – cam track
•          Pickup – drive gears 

Greasing 

All balers come fitted with a number of manual greasing points which are easily accessible throughout the baler, either individually or through a centralised greasing block. The following bearings highlighted below are greased: 

•          Bale chamber – drive side
•          Bale chamber – non-drive side
•          Rotor bearings – drive side
•          Rotor bearings – non-drive side

The McHale V8940 and V8950 are fitted with an Expert Plus control console, which has a large graphic display. The console also gives the operator the choice of selecting a soft or hard bale core, depending on the customer’s feed out requirements. The control console can also store ten bale count totals, so the operator can record ten different counts that may be associated with different fields or different customers. 

From the control console in the tractor cab the operator can adjust the following: 

•          Core size and bale size
•          Core density and bale density
•          Revolutions of net being applied 

The McHale Expert Plus Control Console also features: 

•          Knife display
•          Door position display
•          Pre-net bale formation alert
•          Net usage (metres)
•          Bale size setting
•          Bale size display
•          Drop floor display
•          Lube count
•          Lube alarm
•          Net layers
•          Bale density
•          Bale shape indicator
