4ft Flail Horsepower Requirement?

[Base Farmer Andrew R]

As above, for field margin topping without taking more crop than I need to therefore need to find narrow compact tractor but balance power requirement as don’t want to be crawling round. Thanks

My 135 with wheels set as narrow as possible on a dragone1.4m flail mower is about right for power and forward speed.

How narrow can you get a 135?

I run a 4ft on a jd 855 which is 19hp on pto. Wouldn't want any less on heavy going.

Shameless plug. I've a real strong wessex 6ft for sale. Ideal behind a 135 or Ford 4000. Proper smart bit of kit. Shame about the blistered pressing

I’m suprised you lot are getting away with 20 ish hp on a 4 ft flail.ive stalled my 6620 on a 2.8 metre flail before in really heavy going.

Think it's all relative. We're not talking cutting a foot of wet grass at 15kph.
25hp Will trim 4" down to 1"

You're going to want more horses and a stronger flail doing field margins

12.4 wide rear tyres on my 135 and it will narrow down to 64” overall width. Mower is 1.4m cutting width and 1.5m overall wide. Book says it needs 25 to 35 hp.

I have a 2.4m Kuhn flail which takes more power to run compared to the 1.4 m dragone. The Kuhn needs 100 hp minimum to travel similar speed to the dragone in the same two feet high mix of grasses, cow parsley etc. The kuhn mulches the mowings more which I guess is where the extra power is needed, along with bigger rotor and heavier flails etc.

I run a 1.2m Ferri flail with two rows of stationary teeth and whale tail flails on a NH Boomer 25, with me acting as the TMS (hydrostatic transmission) I can end up travelling slowly in heavy going but rarely stall it.

1.2m kubota flail , boot flails. On stw 37hp kubota. no problem.
All depends how thick the stuff you want to chop and how fast.
