[quote="huw williams"][quote="mrP(Boonen)VT"]Not on my ride to work - it's too short (and too early) to think about anything in the morning (and too tired) in the evening, but on the 12 hour, I did gaze across at the fields and wonder how much horsepower a tractor has etc
Why, are you thinking of getting one for your new country estate? If so here's some advice on horsepower:
How much horsepower do you need? Once you have a handle on the types of jobs your tractor will be tackling, you can work with a dealer to determine what horsepower you need. Horsepower is the most basic distinction between tractor models: it dictates what work the tractor can perform, what types of attachments it can run, and, to a large degree, how much you'll pay.
Tractors with less than 25 HP make up the small end of the market. They're capable of handling most basic lawn work, but often can't provide enough power for more demanding jobs like tilling or heavy brush mowing. Between 25 and 65 horsepower is a comfortable middle ground that features tractors with capabilities suited for ranchette communities, horse farms, nurseries, and many commercial uses. Above 65 HP, you get into tractors designed for strenuous agricultural use, such as tilling fields and baling hay. The largest tractors for commercial farming feature 200 HP engines or larger.
Be aware: in some tractors, the horsepower available to attachments through the power take off (PTO) connection is less than the overall engine horsepower. Some attachments have more specific HP requirements than others, so make sure you check these ratings carefully. Once you know the general range of horsepower you're looking for, the best way to narrow it further is to talk to a dealer who carries a wide range of different brands and models of tractor. The best dealers, like those on the BuyerZone network, will ask you specific questions designed to help them determine exactly how much power you need. When it comes to tractor horsepower, there are problems associated with both overbuying and underbuying. Buy a tractor that's too small and you may not be able to complete the jobs you have in mind. Buy one that's too large, and you'll be wasting money, as well as increasing the turning radius, clearance requirements, and damage to the ground.
But what does that actually mean in power capability terms?
Well let's say you went for a 50hp tractor - quite modest but that's still the equivalent of 37,300watts - which in club run terms would be like getting 124 riders each putting out 300w on the road at the same time.
Or a 200hp tractor which puts out close to 149,000 watts - the equivalent of 372.5 Georges with an ftp of 400w
Hope that helps with your choice and by the way, there's a small lawn in back of my flat which needs furrowing if you're in the market for a bit of private
I wonder no more.
