This was taken from the manual and it was helpful for me to see what implements to purchase and the size and weight restrictions. Hope this may assist if you do not have your manual handy. This is from the manual that came with my tractor on 1/31/11 with a copyright date of 2007 so there could be alterations in older or newer manuals.

Good info for a baseline. But take some of those figures with a grain of salt.

For example IMO a 6' rotary cutter is just a tad much, but saying the max size for a flail is only 50":confused2: Get real. That wont even cover the tracks.

Same with the boxblade. MAX of 52":confused2::confused2:

And I have also personally used a 5' tiller and it does just fine.

Again, my manual has the same #'s. And they are a good baseline for new owners to go by. But PLEASE, ask around and ask your dealer before you size up implements.

I'd hate to see someone spend the money on 48" flail mower of boxblade for one of these tractors based only on what the manual says. I think an implement that small would look kinda funny behind my 3400

Perfect LD1, glad to know to use it as a "general reference" guide. Since this is my first tractor I would tend to lean on the information given in the manual without having the years of expertise offered here. Since you have basically the same tractor and there are many in this category it will be a blessing to know the inside scoop before I buy something useless.

 

[LD1]

I dont know what you plan on buying but this is what I find to be a good fit for the L3400

Bushhog AKA Rotary cutter....................60"
Rear blade for dirt work.........................72"
Rear blade if ONLY doing snow................84"
Finish mower.......................................72" (I only have a 61" but that is what was avaliable to me at the time)

Tiller..................................................60"
Box Blade...........................................60"-72"

Thats about all I have. I'm sure others will chime in.

One of the most important things (to me anyway) is being able to cover the wheel tracks like when moving dirt, blading, or moving snow. You also want them to cover when the blade is angled. That is why I use a 7'-er for snow.

LD1 is giving you the straight scoop as I know it, I have a little rotary cutter, but that is because it is what was left over from the last (smaller) tractor, same way with the rear blade. I need a 7 foot rear blade for snow not a 5 foot.

My experience is pretty much the same as others in that the implement recommendation in the Operator Manual tend to be pretty conservative. I rely on my own experience, my dealer and the good folks on TBN.

For the most part that is right, except for the rotary cutter.

If someone totally new to tractors knew absolutly nothing, and just went on the basis that EVERYTHING is conservitive, and decided to get one size larger on EVERYTHING listed, they would be just fine on everything EXCEPT.......when they tried to but a 7' bush hog the back:confused2:

 

[ccsial]

Those weights seem awfully conservative.

My 60 inch snowblower weighs in at 375 lbs and my Woods RD7200 mower is 650 lbs. I guess I'd better not tell my L3400 about that since it has not complained for 5 years. and 290 hours.

 

[jbrody44]

Yeah, I run a 6' box blade and a 64" snow thrower both with ease with the L3400 HST. Dealer recommended both and I have been pleased. I don't think the box blade recommended would cover the rear tires.

That is why I added the dealer and other owners into it. My BX2660 Operator Manual limits my rotary cutter to 42", but it handles my 48" really well and could probably handle a little bigger as to power if not weight.

Rotary cutter compatibility is also going to depend on more than cutting width such as light duty, medium duty or heavy duty, 3-point or pull type. Our Case CX 80 had the power for a DS1260 pull type, but not the 3-point.

I would never advise anyone exceeding the Manual recommendations without due consideration to all factors. I just find most if not all Operator Manuals on everything too conservative these days. According to the manuals on my Rhino and Grizzly they don't seem safe on anything other than flat ground operated at a very slow speed in full armor. My pickup has roll over warning stickers and such on it etc. I am not even sure they recommend cutting trees with a chain saw except by a trained professional in controlled circumstances; I should have been dead long ago according to all my manuals.
