Tractor requirements & preparation
5.1 Tractor requirements
The minimum recommended size of tractor for operating the machine comfortably
depends mainly on the forage being raked. On flat ground
McHale
recommends a
tractor size of approximately 45 to 55 kW. On hilly ground or difficult conditions, an
additional 10 to 15 kW is advisable.
The following items on the tractor are required for attachment of the machine behind
the tractor:
1.
CAT 2 linkage
2.
Double-acting hydraulic function (minimum 20 l/min @ 180 bar)
3.
Single-acting hydraulic supply with float function
4.
12 V / 7-pin socket for lighting
5.
1
⅜
”, 6-spline PTO shaft (set to a speed of 540 rpm)
6.
Lower link stabilisers
7.
Suitable location to attach safety chain. The safety chain must be attached in
such a way that if the coupling breaks, the hitch or drawbar cannot make
contact with the ground.
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.
