Starting in model year 2016, there will be three triple-mounted mower-conditioner (TMMC) systems available from John Deere. The R870R system will have a front-mounted F310R mower and two rear 3.1-m (10.2-ft) wide mower-conditioners for a total of 8.7 m (28.5 ft), system cutting width. The R950R will also have an F310R on front but will have two 3.5 m (11.5 ft) mower-conditioners mounted on the rear for a total of 9.5 m (31.2 ft) cutting width. The final and largest system is the R990R. This TMMC system will have three 3.5 m (11.5 ft) mower conditioners for a cutting width of 9.9 m (32.5 ft) per pass.
Transport lock for front mowers
To prepare for transporting, the side curtains of the F310R or F350R Front-Mounted Mower-Conditioner are manually unlocked and folded into the transport position. This will reduce the overall width during transport. The transport lock lever on the front-mounted mower-conditioner is engaged so that side-to-side oscillation during transport is eliminated.
The side shield protection and side curtains are unlocked and pinned automatically to reduce the overall transport height of the TMMC. The side shield protection provides rigidity to the side curtains during cutting and is folded down in transport to reduce the overall height.
When getting the rear mower conditioner in working position with the monitor, the protective side shield, fitted on both side, automatically move in working position thanks to 2 hydraulic cylinders.
When preparing the rear mower conditioner in transport position, the shields will come back automatically in transport position.
Rear three-point hitch may be adjusted, as necessary, to assure the overall height of the mower-conditioner does not exceed 4.0 m (13 ft, 1 in.).
A spring-loaded safety lock on the main frame secures the mower-conditioner in the raised position.
The transport width will be dictated by the transport width of the Front-Mounted Mower-Conditioner, meaning 2.99 m (9.8 ft) with the F310R, and 3.48 m (11.4 ft) with the F350R.
Once the front mower is in transport position, return to the cab of the tractor. To fold the rear mowers into the transport position, place dial indicator (4) in picture below on setting 1 and depress button 5 and tractor selective control valve (SCV).
