Tractor requirements & preparation
5.1 Tractor requirements
The minimum recommended size of tractor for operating the machine comfortably
depends mainly on the crop condition and the required cut length of the forage. On flat
ground McHale recommends a tractor size of approximately 60 kW. On hilly ground or
difficult conditions, an additional 10 to 15 kW is advisable.
The following items on the tractor are required for attaching to the machine:
1.
Low/high drawbar hitch
*
that is suitable for a vertical load of at least 1,470 kg and
a D value of at least 46 kN
2. Two double-acting spools (
½” female quick-release) one with float position for the
pick-up reel
3. ½” male quick-release for the tank return (Must be free flow to tank)
4. Hydraulic-brake coupling (or two air-brake couplings), if brakes are fitted
5. 12 V / 7-pin socket for lighting
6. 12 V, 20 A socket or battery power cable
7. 1 ⅜”, 6-spline PTO shaft set to 540 rpm (1,000 rpm optional). For North
American markets, a 1 ⅜”, 21-spline 1,000 rpm PTO shaft is optional.
8. Suitable location to attach safety chain. The safety chain must be attached in
such as way that if the coupling breaks, the hitch or drawbar cannot make
contact with the ground.

Depending on country of use
5.2 Control box installation
A good power supply is critical for proper machine operation as the electronic control
box is the main interface between the operator and the machine. The electric power
supply is obtained from the 12 V socket of the tractor. Alternately connect the supplied
fused electric power lead to the tractor battery ensuring to route away from sharp edges
and hot surfaces.
NOTE: Use good quality oil
Ensure that the tractor has clean, good quality, hydraulic/universal oil to
avoid problems later on. Also, the hydraulic filters on the tractor should
be changed regularly, according to the manufacturer’s service
instructions. Avoid dirt getting into the hydraulic couplings.
