- Transport is recommended behind a tractor with seven-pin electrical lighting outlet
- 430D, 435D and 440D Drapers only
- Convert draper from field to transport in minutes with one person and without tools
- Dual front dolly wheel tires and two, gauge wheel tires carry weight of transport
It is a simple four-step process to switch from field to transport:
- Move right gauge wheels from field to transport
- Move left gauge wheels from field to transport
- Attach the tongue.
- Detach from the windrower.
Optional reverser clears plugs effortlessly for higher productivity during tough harvest conditions
Platform reverser controls on W155 Platform reverser controls are available for the W155 Self-Propelled Windrower only:
- Easily activated from operator's station to clear platform of plugs
- Reverser slowly reverses the knife drive and optional hay conditioner, if equipped, to clear plugs
- Highly recommended when using optional hay conditioner with 400D Platforms
- Operators can run machines closer to their maximum capacity and it will take less time to unplug
Reverser valve block The reverser consists of a valve block and valves, shown in the image above. It is the gold-colored valve block on the right side. It is shown plumbed for a 100A Auger Platform.
