self propelled sprayers

[Flatlander]

I believe the parking brake is actually a plate pack in the rear wheel motor hubs, thinking about it, when oil pressure is absent, they default to "applied", meaning that in order to to trailer a machine due to a motor problem, you have to screw the brakes off manually with a bridge plate and a long bolt.

My case ih I had was brake pack released by hydraulic pressure. Was a parking brake only but if moving around the yard with low rpm it wouldnt have enough pressure to completely release and would chew the plates up and in turn the debris would foul the sun gears and planetaries neither of the two I replaced were cheap , newer one has air brakes.

Had the main hose blow going down steep hill meeting lorry.... freewheeling about 10 yards before parking brake came on and ground to a halt. Scary for a moment or two. As mentioned above hydraulic pressure releases the parking brake so loss of pressure brakes on.
Always go slowly down hill on road now.
Never had problem with power spraying on hills only 90hp on 2000lit sprayer and still went up at 8kph. Now have 170hp one with 3000lit only running about 1700rpm.
Only do moderate speed though.

we are thinking of buying a second-hand self-propelled sprayer 24 mtrs 3000 ltrs or thereabouts Having looked at websites and adverts I am baffled some apparently have no brakes. then there is the issue of power that seems to vary tremendously even among what appears to be virtually the same machine any help or advice would be gladly received
?

Go for a Bateman RB25 or 26. Brakes are surplus with hydro; pull back on the lever and she will soon pull you up. Watch for oil leaks on hubs and see to them sooner rather than later. Other than that just sit back and wonder why you didn’t go to SP years ago

Relatively flat then looking over from here?

Local contractors slightly north of you had a Jag 900 go down Newgale hill (heading south) with a burst pipe! The driver near on needed new overalls and thankfully nothing was coming over the bridge as he coasted over it!

Because of where you are I’d be looking at househam/Bateman or knight - so either Jim at John Rhoades (by Carew) or Jim and Jason at Trewarren for a knight..

thanks for that if you stand on the beach in little haven and look along the cliffs to goultrop roads that is some of ours there is one point where the back end of the combine lifts up when going down hill

I don’t really know that area, I’ve always stayed north of Newgale as much as I can but I can see your area from the house

Multidrive.

that’s the answer to all self propelled sprayer issues.

Amen.

 

[Adeptandy]

Hmm, I do sometimes regret not trying one

Many years ago, when God was a boy, I had a SP 24m sprayer on demo. To save embarrassment I won’t name names. This machine had hydro transmission with no brakes, save for parking brake shoes that were applied automatically once the engine stopped. I sprayed a field, folded the boom and headed for the gateway which was on a slight downward slope. The manufacturer’s principal had his nice shiny Volvo parked up outside the gateway. As I approached the gateway the engine died and I could hear the brakes trying to grab, but the sprayer very sedately rolled onwards and mounted the back of said Volvo. The look on the man’s face was priceless as I got out of the cab and said “I think you need to get the brakes adjusted.”
The machine that I finally bought (a different make) had a switch to engage the parking brake and never let me down. Having said that, on the move, knocking the hydro into neutral brought it to a rapid stop.

One word on sp sprayers…Batemans service! (Oops that’s two)

We had two covering twenty years and the service , even on bank holidays or Sundays was superb.

whats this wont cross the Landsker line scared of what you will find down below

So good you bought a Horsch!

I’ve an old Bateman Hi-Lo, no brakes takes a bit of getting used to. Observers watching me meet a car on a blind summit would think I’m dancing to an early 90’s techno tune but it’s just me trying to figure out how to stop till I remember

 

[chaffcutter]

@Chae1 Would definitely have had another Bateman if we justified the cost of a new one-but with less to do and the tractor driver now doing the spraying it was a no brainer!

 

[willyorkshire]

Whatever you do, don't buy Mazzotti. Even if it's near new, don't touch it. Absolute nightmare.

^^^^^^This

the hydrostatic machine with wheel motors have in built brakes in the rear motors than need hydraulic pressure to hold them off just as a truck on air brakes needs air pressure to move


in normal operations pulling back on the lever give braking force through the hydro system
this is greater at high engine revs
this meets road regulations for ag machinery

any one with a fully ladened sprayer should not be going flat out too high a risk
tractor powered or self propelled
