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 85 kW. On hilly ground or
difficult conditions, an additional 10 to 15 kW is advisable.
Ideally the tractor should have a load sensing hydraulic system, as the machine works
at it’s best in this setup.
(See ‘Machine set-up & the tractor hydraulic system’)
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 1,800 kg and
a D value of at least 50 kN
2.
½” - female quick-release single acting, with ‘float position’ for the pick-up reel
3.
¾” - female quick-release for hydraulic power supply of minimum 45 litres per
min @ 180 bar
4.
¾” - male quick-release for return line (must be free flow to tank)
5.
⅜
” - female quick-release for load-sensing (only required if the tractor has a
load-sensing hydraulic system)
6.
12 V / 7-pin socket for lighting
7.
12 V, 20 A euro socket or battery power cable
8.
Two air brake couplings or one hydraulic brake coupling*
9.
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.
10.
One secure attaching point to tie the ‘break-away-brake’ rope to the tractor
*
Depending on country of use
5.2 Control box installation
The control box is to be connected to a 12 V, 20 A power supply either using the
supplied euro socket or the battery power cable.
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.
