Experience w/ 3-point trencher attachments?

[aaroncmh]

Hello, I was wondering if anyone out there has had any experience with a 3-point hitch, PTO driven trencher?

I was trying to find out how well they work. I would be trenching mainly 24" for conduits...some applications will require 36" so I would get one that could handle that depth as well.

I can tell you too that it will be ran by something similar to a JD 3320. I don't have the tractor yet but if I can use it for work then I can justify a bigger, better tractor. ha, ha

Lastly, it won't be used every single day all day like some equipment...if that were the case I'd think a dedicated trencher machine would be the best bet.

Thank you in advance,
Aaron

I've rented a PTO 3 ph trencher for use on my 4300 (basic same frame size as the 3320).

It worked very well.

I had given some thought to a 3pt trencher until I learned a new one from a reputable manufacturer would cost over $6k. There would be no way I could justify such an expense, particularly since I already have a backhoe. I have to put in some irrigation lines, but I'll either use the backhoe or rent a ditch witch. You might be able to find a used one for less money, but watch out for something in rough condition... a trencher is likely to have seen some severe use.

Any idea what brand you rented buddy?

I haven't seen one for 6K yet...the ones I've seen are 3-4 but I don't know if they are any good. That's why I asked for some experience. And yes of course you have to have a good reason to buy such an implement.

I don't recall which brand it was. Worked well, that I do recall. Ran tile lines and lawn sprinkler lines, but it was about 8 years ago. I'll check into it. Thinking it was a Ditch Witch, but don't know for sure.

The one I checked out was a Bradco... a top line manufacturer of commercial duty tractor and skid steer attachments. I recall it was in the $6k range, which seemed reasonable to me considering how it was built. On the tractor version, the chain ran from the pto and the raise/lower mechanism was hydraulic. The skidsteer version was all hydraulic. There may be less costly units out there, but even $3-4k wouldn't be justified for my situation.

Thanks Beenthere if you think of it that'd be great...don't dig too hard (no pun intended).

Granddad my situation would justify the cost...if it works well that's why I'm asking for opinions.

I've been told that geared machines won't go slow enough to use the trencher.
The crawl gear/speed that some Hydro machines have is said to be perfect.

That said, I've never seen one for rent or I would have tried it anyway. My backhoe bucket is 16" and it makes a mess trenching.

 

[Grandad4]

That would make sense. If running my 6ft. tiller is anything similar, you need the HST so you can slow down enough to let the implement do its job. Even the walk-behind trenchers creep at a snail's pace.

Having spent a lot of time on a full ride on ditch witch trencher which actually runs the chain off of hydraulics I can tell you that you have to be able to go slow and steady. On a tractor with hydro you would have to move a little, and then stop, move a little, and then stop. I would be willing to bet that a crawl gear on a tractor would still be too fast.

It would not be the best set-up for $6K. The ditch witch has a crawl function that works well, and usually you need to set it at the lowest setting when digging anything over 12". Making curves is really hard on everything too as now you're putting force side to side on the 3-pt etc.

Also half the work in trenching is covering up the ditch. Not sure how well you could do it with a std. bucket. The trencher has the angled front plow that backfills like a champ.

Oh really a trencher works well for trenching?

I was asking about a 3-point trencher...I've used Ditch Witch and Vermeer models for years. I want to get a 3-point trencher and then I justify a better tractor (if the 3pt style works well).

And yes you have to have the Hydro...and you can backfill with any bucket. Ever used a skid-steer to backfill? It can be faster than the trencher blade.

Thanks Beenthere...

My tractor was set up for trenching with the lowest gear producing 60' per hour @ WOT. Its a Jinma 284 with the extra creeper gear box for a total of 12 gears forward, 3 in reverse. There is no way my Ford 861 would go slow enough.

I do not have a trencher so I could not tell you how it works but I am sure its fine. I love the slow speed for removing stumps and jobs like that. Use it all the time.

Not saying it won't work. Buy it and then post up how you like it.

Good luck.

I'm sure its overkill for your application, but check out DK Precision Trenchers they offer 2 models, a 612 and 628, the 628 being capable of 100'/min digging a 10"wide by 36" deep trench. max depth of both machines is 6ft. they also have the advantege of automatic grade control. the small one requires 150hp, the 628 needs 200hp.

FYI, all the grey market Japanese tractors are set up for tillers. They have gears so slow you can set them to PTO rpm in low gear and get off and put a mark on the ground to be able to see they are moving.

Hi, I have a Dual/Woods three point trencher that has a hydraulic motor to propel the trencher wheels. This unit also has a hyd ram that lifts the back of the tractor and consequently shifts rear tractor weight to trencher wheels for traction. I set mine up so that the rear tractor wheels barley touch the ground. Trenching speed is set by leaning back and setting the trenchers speed valve to the speed required. Chain is run by tractors pto.
I have this setup on a JD 9 speed 970 tractor. And have trenched with it for over 10 years and it works great.
Don't know if this unit is still for sale, the original manufacture Dual, was taken over by Woods some years back.

cheers,
