The gearbox is fitted with a rear PTO shaft which turns at the same speed
(rotational frequency) as the tractor drive shaft. This rear drive shaft
should not be used to drive a secondary machine while the gearbox is in
its neutral position (due to the risk of gearbox damage resulting from
inefficient oil circulation). The rear PTO shaft (1 3/8" 6 spline profil)
should not be used to transmit more than 50 HP.
III. 3-POINT LINKAGE WITH HYDRAULIC LIFT FOR ADDITIONAL IMPLEMENTS
(No 120 7700) (Photo 4)
The 3-point linkage with hydraulic lift reduces the overhang of a combination (EL
100 N-seeder, for example) by lifting back the combined machine over the Power Tiller
by means of the hydraulic cylinder (V).
This transfer of mass makes it possible to gain up to 25 % of the tractor lift capacity.
The linkage is equipped with a pivoting frame (P) which can be adjusted in two
positions :
- Lower position (as fitted at factory) : recommended for use as a combination with
non-PTO powered machines.
- Upper position : necessary to enable fitting of PTO shaft when combining the Power
Tiller with a PTO powered machine (for example a pneumatic seed drill). For this
purpose a set of adjustable stops (E) (No. 120 76 90), available as optional equipment,
can be fitted to the front frame (F).
