May i ask how many acres you cover in a season , and what do you recon ,it costs you to run spray outfit per acre ,This is something I've been thinking about quite a bit. It really does depend on field size and shape. The output from the Horsch tanking along at 25 kph putting on fertiliser gives a mammoth spot rate, but to make use of this you really do need big fields, otherwise you hit that speed for a few seconds a run and never on the headlands (which can be half the field area in smaller fields). I can do a 30 ha field in an hour on one farm, whereas a 13 ha one took me also an hour the other day due to poles and it being the first time through it with that machine.
I have found that a 36m Horsch with an 8000l tank and an 8000l bowser will struggle to get done what our old 24m Spray Ranger and 24m RB17 Bateman could do in a spraying day. That said, we are getting still quicker and quicker at using the new setup, which has been improving output, but a decent day on the Bateman was 300ac, whereas a decent day on the Horsch could be 500ac. As soon as you throw in telegraph poles / in field trees, the work rate plummets. It's made me realise how costly electricity poles are in killing output and requiring more capacity to get work done. Other people tell me they do 1000ac in a long day. I cannot see how I can get close to this at the moment.
Where the Horsch really steps it up is on fert. My best day so far was 85 cube of fert, and I think on our bigger fields we could do 100 cube. The Bateman I think would struggle to get anywhere near 50 cube (although that's not fair on Bateman as it was a completely different machine not specced for liquid fert). We now put all the main N dose on in one go, and at speeds that we never did with the Bateman, which gets it on at a less scorchy and less risky time of year and saves a pass. This year I waited until the day before rain was due and then did all the wheat in one day.
As we are considering removing more land out of production, there is no doubt that a new Fastrac and Horsch is a big part of our machinery value and puts a big number on the annual machinery depreciation. I've said this already, but the old system was probably cheaper spraying, but with safety concerns and a possible retirement of people, it would not have made sense to replace the old system with two new Batemans say. However, if I was farming more like 4000ac, I might think harder about the economics or running two Batemans. The depreciation they have or don't have really does make a big difference to running costs, whereas a Horsch is much more of an unknown, and, despite their outstanding engineering design and attention to detail, there is a lot of wiring and complexity there if you ever needed to strip a boom down.
I think, being honest, there was a bit of shiny kit syndrome in the decision. I now reasonably enjoy spraying, whereas I used to really dislike it due the improvement in a lot of little small things that add up. There are a lot of people running in unsafe cabs and filling in unsafe ways, and our new system deals with both of those issues that we had before. In the end, I decided my own health and exposure to HSE prosecution as the person who has overall responsibility for everything was worth the spend.
Dont have shiny kit syndrome here , if we changed to same sprayer as got now with , section control and the latest gadgets ,with all the bells ,would be around 70 p acre all in ,would cost £50000 to swap , but at 8 year old and nothing wrong with it ,just done pump ,and fitted 2 more sections ,and have a little matrix 430 ,which shows sections , and switch manually ,and pull it with an immaculate 13000 hr tractor ,we did buy another this time ,to go on sprayer but like the old one best , ,
We demo a horsch last year ,but the crops are just as good and as clean using old sprayer , cannot justify the extra chunk to change to one , the cash is better invested in more irrigation ,,now if we like bannana or your self dong 4000 acre multiple times it would be considered , we have a berthoud , because of the service and back up ,boston crop provide
