You choose a brush mulcher based on what's left on the ground after pruning, not based on power. In vineyards it's thin, long canes from the current season that tend to wrap. In orchards it's thicker branches that need to be shredded, not just cut. In grounds maintenance it's a mix: tall grass, brambles, suckers, pruning debris, the occasional rock nobody spotted. Each situation calls for a different rotor.
Blades or hammers
A blade rotor cuts: Y-shaped knives spinning at high speed, suited to grass, brambles, and thin canes. It leaves a fine mulch and draws less power. A hammer rotor pounds: heavy flails that break up branches and wood, handle rocks better, and leave a coarser mulch. In a well-managed vineyard blades are enough; in an orchard with thick wood and on rough ground you need hammers. Operators who do both buy hammers and accept a slightly coarser finish on grass.
Working width: more important than the engine
The working width determines the number of passes and must fit within the row spacing with enough margin to steer. A mulcher wider than the machine carrying it is a mulcher that will get stuck at the first pile: the practical rule is a width similar to that of the undercarriage. Where row spacing is tight, a compact brush mulcher on a compact machine does in one pass what a tractor can't manage by fitting through.
Tractor, mini skid loader, or tracked multi-purpose machine
Behind a tractor the brush mulcher is the classic solution, and for wide rows it remains the best one. Problems start where the tractor can't get in or can't hold its position: tight rows, terraced land, embankments, slopes, hillside orchards after rain. There, the compact tracked machine makes the difference not because of the mulcher, but because of the undercarriage: low ground pressure, low center of gravity, no compaction of wet soil.
The wheeled mini skid loader is the middle ground for yards and dry ground; on wet surfaces and on a slope the track holds where tires dig in.
Where Cormidi fits in
The CMF multi-purpose machines and the mini skid loader mount blade and hammer mulchers on the attachment plate; the C85 in quick-attach versions has its own dedicated mulcher. The logic is the same across all of them: the same tracked undercarriage that mulches in the morning and hauls material away with the skip in the afternoon, passing through a garden gate or a vineyard headland.
Three things to check before deciding
The thickest material you actually encounter, not the average: that decides blades or hammers. The tightest gap you need to pass through with the mulcher mounted: that decides the width. The gradient and soil type during the period when you mulch, which is usually wet: that decides between tires and tracks. The local dealer can let you test the mulcher on your own rows, which is the only test that matters.
