Glad to see your grass at same stage as ours.
That was contract work up in the hills they don't chop till into July. But our first cut at home isn't an awful lot better for being due to cut in 4 weeks

No idea. What Fastrac are they off?
Don’t know, just seen them online but thought most Fastrac’s were on r44 rowcrops so was afraid they were too tall.

Don’t know anything about row crops but they must b a foot taller than the standard wheels? They may fit but might be close in places? The Knight forward control has bigger wheels because of the mods.
That is my thoughts too, some searching last night showed the forward control can fit 380,r46 . That’s a fair tyre ?.
Yep it’s a common JCB steering wheel ?
It's a different shape if spinner and wheel but they may well fit each other

Knights modified the panniers to make those big wheels fit, the exhaust was moved and it had fabricated hydraulic tanks.
710/60 r30’s are 1620mm diameter and they’re fairly tight against the panniers. Think the factory rowcrops are 380/85r38

Cheers I’ll give it a try and see how it goes
So as it's bloody wet and can't get on with anything else I finally managed to get this for a proper try out .
I ran across 600 acres yesterday with it and it's very comfortable and manouverable with the 4ws .
But !! This may have been me not using it properly I felt it a but lacking on a hill.
Set up in 540eco at 18kmh as I would with my JD'S using the rev hold function and when it came to a steep bit it would drop 100 rpm at the shaft before slowing the forward speed and then getting PTO speed up again. Is there droop settings to change this ?
Gonna stick the trio on it and see how it goes but it was pretty wet last night .
But only once I've removed my spreader and box etc . Simple spreaders used to be easier to put on a different tractor

The setting in green below is ‘droop’. You can set it for a minimum of 100rpm which is about 40rpm at 540e.
That will probably help then I did look in there but didn't pick up that as being engine drop I'm used to a percentage. And a lack of autosteer didn't make it easy to play with it unless I was stopped

There is a setting in the gearbox settings to set the maximum rev drop before it pulls the gearbox in, its the bottom option in that page, I usually have it set to 150-300 depending on what job the tractor is on.
*edit* beaten to it!

Think the options things are inaccessible at 18k anyway.
