It was a comparison. Average farmland price £10k per acre,average topping price £35 per acre. Seeing as farmland is ten times that down here, it's fair enough that topping is more expensive!
As it happens, I don't think I was a total rip off merchant in this instance. 4.4 acres topped, so £45.45 per acre. It made me £50 per hour less £5 worth of diesel per hour (hours include transport and truck diesel too), so £45 per hour. Not mega money but scale that up across a few different machines out each day (we are local work only) and it's a respectable business with plenty of happy customers and reccomendations. Say what you like, but there's plenty that put a 6t machine out for that money! I'd much rather have the three diggers, two dumpers, compact loader, mini loader and two compact tractor- all for less than the price of a 13t and tilty new!
You could have gotten a larger tractor in on this job, but often you can't. I doubt it would have been
that much quicker (maybe a 8 or 9ft topper? can't go much faster otherwise you miss lots), and capital outlay would be much greater. That Kubota was £15k new inc the topper (5ft but I reckon she'd run a 6ft). It fits easily and quickly on a trailer and can be 'roaded' at 50mph. Why would I want to have a bigger tractor costing £80k new just to do the job half an hour quicker yet burn three times the diesel getting to the job?
That hydrostatic transmission makes the job so simple too. My only bugbear is that the cruise control isn't great- it always sets lower than when you engage it, and there's no easy way to adjust it. You have to take it off, set the foot pedal speed again and engage it again- whereby it promply locks at a mile an hour less than you wanted.
