Hi ,
i am owner of a 455 (diesel 22hp), 3ph cat 1.

I am considering to buy a tiller (non hydraulic), and i am wondering how wide tiller can i use

JD 450 tiller is 50 inch wide, so has JD 455 enough power for it?

thx for advices.

In the JD 455 equipment compatibility table it is the 450 tiller listed to go with it. So it seems John Deere intended for the tractor and tiller to work well together.

If memory serves me right, your 455 has about 24 HP, the JD 1023 has 23 HP. I believe the soil your trying to till would be more of an issue and that can be handled by taking shallower passes. I would not worry about it.

I have 2 extensions on my Mod 33 tiller making it 44" wide. I use this with my 14HP 314 and have never ran out of power. Your extra 6" plus 8HP will handle it fine. Bob

My 430 (1 generation older than your 455) handles my JD 48" tiller without problems. The 430 is rated at 20 HP, but experience tells me it has more "umph" than my 445 which is the gas version of your 455.

You should have no problem with the JD tiller.

I have had a 450 tiller on my 425 since I bought it in 1969 and it's always worked fine. I do use 5 suit case weights on the front.I also bought another PTO shaft so I can use in on my 1025R. The 425 fits in more spots but the 4wd is nice to have. So a 455 should be just fine.
My 445 came with a 450 tiller.

Put weights on the front and have at it.
Thank you all guys for advices.
I am thinking about real conditions, even uncultivated land (but not rocks).
ive found here in europe Stark tillers, but manufacturer mention a little bit different data about required horsepowers. So bcs of that i mentioned JD 450 tiller (pretty much same machine, ).
53 inch - 30hp

49 inch - 25hp
lets see the picture.

I’m in Europe as well. Take 95/105 maybe 115. Problem with bigger is no power of tractor which is enough but weight of tiller, problem with lifting and your hydro. Because 455 has just one speed no crawling my friend which bought 125 tiller start have issues with hydro, start to slows, problem with lifting after warm up. With smaller tiller was no problem at all.
If memory serves me right, your 455 has about 24 HP, the JD 1023 has 23 HP. I believe the soil your trying to till would be more of an issue and that can be handled by taking shallower passes. I would not worry about it.
425 Has a PTO HP of 16
The 445 & 455 Had a PTO HP of 18
X465 through X700 signature series all have a PTO HP of 18

I ran a Used JD 425 1994 Model I Bought in 2000 and used a 450 tiller for 3 years No Issues with the 16 PTO HP Had Bought the 425 with a 42inch Hydraulic tiller Previous owner Managed to Poke a Hole In the Hydraulic Tank so dealer Gave me the 450. Great tiller I should Have Kept it when I Bought My X485 In 2003. 450 was Offered as the PTO tiller for the X400 thru X595 Until Deere changed to the X700 Ultimate series and started Marketing the 647 as the tiller for the X700 Ultimate series (y)
