Meanwhile, on this side of the pond, we tend to get the brush mowers either as wide as the tractor or most of the times about 4" narrower than the tractor.
This is done for a couple reasons:
- Maneuverability. We're always in tight corners or with trees everywhere.
- We use grade 80 chain instead of blades as cutting element. While this will eat pretty much anything (grass, all kinds of brush, small trees (up to 3"), rocks, whatever it catches), it will also eat a lot more HP and demands much more from the tractor versus the blades and won't get damage like the blades would. So you can't really go much bigger, if you don't have the HP.
90% of the brush mowers here come from factory with chains (blades are optional). I'm running 1/2" Grade 80 chain, smaller mowers use 3/8" and big ones use 3/4".
Just to give an idea on the HP these things eat, I'm running a 4 ft mower on a 35HP tractor and the only time it will bog down is with very high and dense grass. Using the rule of thumb that you guys use with the 5HP per ft, that would equate to a 7 ft mower fitted with blades in the US.
