how big of a tiller can you run on a 2920?

[MattEffinCameron]

So thats it, how big of a tiller can you run on a B2920? I think the answer is like 48"-54"?

I ask because I borrowed a trailer from my brother to move my new B around a bit, and he also left his PTO tiller on it...but its a 72" (king kutter II). I would never expect the 2920 to be able to run this thing, its massive...but I have it at the house...and I need to till this new garden area I just plowed yesterday....will it work but just be slow going? will it break stuff? or is it just a waste of my time to even try hooking it up?

Matt, I have a B2650 that I think may be about the same size as your B2920. I also have a King Kutter 72" tiller from when I owned a 50hp L5030. I would think it is much too large for my B2650 and I don't plan on ever hooking it up. When and if I can afford it I will most likely purchase a King Kutter 48" - that seems about the right size for my PTO hp, even though it won't fully cover my tracks (I think it can be offset?). If you do get brave enough to hook up the 72" please let us know how it works and how much damage it does to your tractor. :laughing:

What damage would it do?

I haven't got it yet, but have a new B2650 and several attachments coming next week and one of them is a 58" land pride rtr1258 tiller. I don't forsee any problems with the 2650 handling it. HJT

I wouldn't think it would break anything, just be a little slow going if the ground is really hard (dropping RPM on the tractor if you go too fast). If you've plowed the ground already, I don't think you would have any issues at all.

My biggest concern would be whether the tractor has enough oomph to pick it up. If it can get it off the ground, you're good to go!

 

[jrepp44]

What damage would it do?

I really don't know for sure - maybe none? My concerns would be overloading the internal parts of the tractors PTO drive mechanism and bending the lift arms if you weren't careful to drive in a straight line.

Please follow up and let us know how it works, I would like to get a 58" if it will work.

My BX2200 runs a 60" tiller just fine with 16hp at the PTO. Would think the B would handle it just fine.

 

[beckmurph]

I ran a LandPride rtr1258 with my b2620. It handled it with no problem. :cool2:

offset 48" tiller - $1095.95 I have the 5' model for my NH TC30, rugged and works well with my 30hp tractor

You've already broken the ground with a plow, and the B2920 is no sloutch on power for it's size, so I'd bet it would do just fine ...
... provided you don't try to till down to China or try to finish it in a big hurry.
Slow ground speed (< 1 mph) & medium depth ( 3 - 4" ) should give you good results.
No need to fret about covering your tire tracks, either.

I run a 48 inch tiller with my B2620. Works great. Could go bigger. With it plowed I would try it. You'll know soon enough. Btw you don't turn with it in the ground.

I wouldn't buy one that big for it but you have an opportunity to try it.

 

[McREBEL]

I plan on getting a 60" for mine next spring. Why not give it a shot and let us know how it works out. Think slow and shallow.

 

[nspec]

60" on a b2630. Don't even know its back there.

 

[tlj87]

60" king kutter II tiller on BX2370-1, no problems. I already had the tiller though and have a larger tractor as well.

Rotary tillers and rotary cutters both like five (5) PTO horsepower per foot of width. The shock load of a too large cutter or tiller on the PTO drive system could have one asking a dealer why the costly repair he is talked about is not covered by warranty.

I have heard this before....but the b2920 has 21 pto hp, so that means a 48" tiller/rotary/snowblower(I have heard the same measurement there as well)?
it seems like "everyone" runs a 60"-64" snowblower on their B series and a lot of people in this thread are running more than 4' tillers on B series or even smaller BXs...where does this rule of thumb come from and who has seen that limit demonstrated (seen a tractor fail to run something over the 5hp/foot or break when trying to do so)?

Also, the shockload you are talking about would only apply if engaging PTO with the implent engaged right? (like with the tiller in the ground)

I was thinking of tilling along and all of a sudden the tines encounter a large rock, or hard packed soil. I have seen tillers stall tractors before. Shear bolts and slip clutches are a must have item when using a tiller or a rotary cutter or any other PTO operated tool. The PTO is going to try to keep spinning regardless if the implement has stopped and the weak link in the chain is usually what breaks. It is an expensive repair when it is in the PTO, drivetrain system. The one extra foot of width will not save that much time if you have to crawl along to use it.

I personally use five horsepower per foot of width. Of course that is for my equipment. I believe a person should use whatever size equipment he wants too. After all, it is their tractor and they are the ones responsible if something breaks, not me.

 

[Gary Fowler]

Shock loading or rather preventing it is the job of the slip clutch. I don't know of any tiller that doesn't have one. As for power, I don't find that they take a lot of power to turn the tines. I think the only limitation to a reasonable size would be the weight. If you look in your owners manual they should state the maximum weight of a 3 PH implement. This it not the lift capacity but rather the weight that the tractor can safely handle. I know that my Kubota B26 could not handle the weight of a 72" tiller (I think 48 or 50" was stated as max) so I decided that I would put one on my 70HP tractor instead.

Recently bought the 58" Land Pride for my B2650 - kinda wish I got the 66". Don't even know there's a tiller back there right now, and feel as though it would handle a 72" as well. It may be a little harder on fresh ground break, but you typically only do that once..... Maintaining a tilled plot is easy.
