Trenching with a Kioti

[Fallon]

Tapatalk dislikes multiple attachments apparently

Tractor mounted trenchers are PTO driven only. Need Hydrostat transmission and 1 rear remote. No one in Texas rents them that I know of

Why no one in Texas rents pto driven trencher? Too expensive?

Only gasoline engine driven trencher there?

A friend has a Kioti with FEL and 3Pt; I'm guessing it's a CX but not sure.

This is for a Ground Source Heat pump which would need 3 ft+ depth.

Would he be better off to rent a 3pt hitch trencher, or a skidsteer attachment for the FEL?

The Kioti CX2510 has a 11.3 GPM pump.

I'd think a tractor with hydrostatic drive would have sufficient GPM, but I'm no expert.

I will reference Bradco Trenchers as they have the widest offering in the market with skidsteer and 3pt trenchers. They also have been making tractor mount trenchers for several decades. I have never seen a 3pt trencher for rent so I am not going to go into details on them, unless Op plans on buying a unit.

The smallest ss trencher 625 is 14-22 GPM and is available with up to a 48" boom.
The next smallest is the 640 and it is 14-24 GPM with up to a 60


The tubing for the lines on a Kioti CX2510 is most likely 3/8" and therefor they cannot flow the full 11.3 GPM, Also the tractor might not have enough fluid to handle the continuous hydraulic load. If the 3rd function line uses 3/8" body fittings were the loader attaches to the tractor like many in that class do they are only good for 8 GPM.

Your likely to discover that one rents 3pt trenchers. Your friend is short on hydraulic flow so using the tractor with a skidsteer trencher to install the lines is not feasible. I hope that the data is useful in your decision process.

Also out of curiosity is he in WA or WV? It might make a difference in alternative recommendations.

Be sure you verify the depth you need first.

The Kioti CX2510 has a 11.3 GPM pump.

Those 11.3 GPM is the flow of both pumps (steering + implement pump) which are different circuits and I don't know why they list it like that in the spec sheet.

The CX2510 has 6.5 CC pump for the steering and a 10 CC pump for the implement circuit (loader, remotes and 3 pt). At the rated 2600RPM, the 10 CC pump puts out about 6.8 GPM, even less than that if we account that most gear pumps are about 90% efficient.

Yep, your right only 6.86 gpm. Had to look at the owners manual. Thanks for the correction!

This makes the decision easier for OP. The tractor cannot do it with a skidsteer trencher.

CUTs top out at 8-10 of hydraulic flow. Usually less, especially with hydraulic losses. At 2,500psi that's only 18hp as a best case scenario, probably more towards 10, maybe 15hp of usable power. That's pretty low to cut a trench 3' deep & 6" wide. The smaller push ones are usually 18", maybe 2' and only 3-4" wide.

It has been a while, but I researched and calculated the horsepower of my Kubota L4060 hydraulic capability at 14hp. That was assuming 100% availability of the implement pump available with no losses.
