Mulch covering disks have positive depth control and adjust
without hassle (below). No tricky disk angles. No disk hopping or gouging.
Coverage consistency is the key to mulch security.
The mulch layer frame hinges behind the bed
shaper. Operate with rigid tuck wheels for accurate depth control of covering
Use rear gauge wheels to transfer mulch layer toolbar weight
behind the covering disks. Floating tuck wheels free excess toolbar weight from
mulch edges and make mulch rows much easier to start. Rear gauge wheels also
press covering soil, which is an added benefit until the next rain fully settles
Ultimately, rear gauge wheels are a personal preference and
not essential to operation. Mulch layers have long been used without rear
gauge wheels but some brands suffer from poorly applied coverage components.
Rear gauge wheels make a mulch layer exceptional.
