Type of soil & how deep you have to dig are couple of points that will dictate size of machine.

I have a Bobcat 435 and do some sewer line replacements. Never seem to have an issue with it being too big. Occasionally I will get in a spot where I need a larger machine, then simply rent.

A 45 size ex will be good for about 9' of depth, they can dig deeper but you loose efficiency at 10 or 11 feet.

I have a 305 cat. Works great. Any smaller and you will be fighting depth problems. Any bigger and backyards become an issue of getting in. If you need to get deeper its pretty easy just to bench in a 1' or 2. I pull my 305 behind my 1 ton.

Re: Best Size Mini Excavator For Water/sewer Tie Ins


I was going to suggest a 308, but since you said that was too big, I guess that is out of the question. You should look into a machine that has a center swing boom and has offset boom. They do not make them anymore, but the purple Komastu's are ideal. There is only utility contractor near me that is buying them all up.

Re: Best Size Mini Excavator For Water/sewer Tie Ins


308 is a nice machine but rather big for what I need I was leaning more tward a 305 or ecr58, pc50. my 1 ton has a factory gvw of 11k and with some helpers + 2k so i was looking for something 12k or under my trailer is a 15k. I've ran a volvo ec55b pro it seemed to have plenty of power and a good digging depth realy like to have a zero swing.. wish my company had more mini's I'm on the main line crew so everything sitting on the road is huge the smallest machine on site is a volvo ec140blc we really have no need for anything small..... well my crew at least!!

Thanks for all the replys everyone, good info quick responce!! apreciate it

little machine, pull a box, or get a machine large enough to get your spoil pile far enough away from the excavation at the proper slope to be safe.

Re: Best Size Mini Excavator For Water/sewer Tie Ins


I actually have 2 aluminum trench boxes.. my company had them for extras he only likes to run steel boxes so. I bought them for a great price.. he gave me a couple extra sets of diff spreads also!!. they are small little things only used at connection spots 1 in front next to street.. and other in back t'wards house. I can move them by hand so I don't thing a mini will have a problem moving them in and out of the hole!

Re: Best Size Mini Excavator For Water/sewer Tie Ins

Look around some more. I paid 29 k for my cat 305. 1700hrs. And it has cab and air. Got a new hydraulic thumb and a brand new 24" bucket thrown in for that price.

Re: Best Size Mini Excavator For Water/sewer Tie Ins


I do a lot of sewer and gas lines and my yanmar vio35 was nice to pull and worked very smooth but it was kinda small , with a short reach and It seemed that i was running close to full power a lot of the time.
I thought that a u50 kubota was very nice .
I ended up with a bob cat 435 with 300 hrs I traded my vio35 and 12000lb trailer + cash for the new ex and new to me trailer.
I like the 435 It really trenches well . and not to big.
It seems to weigh in at 11, 500lbs+

Wish our sewers were only 5' deep. Most lot stub-ins are from 14' to 10' deep. Dig everything with a 200 Deere 48" bucket. I like shoulder room lol. Weighs in at 45,000 the skidder trailer didn't handle it well.

Re: Best Size Mini Excavator For Water/sewer Tie Ins


Yea I was actually suprised on the depth also, most stub we put in are around 8'-10'.. but the town was very firm on the 5' stub Idk.. Maybe Its a Connecticut thing.. either way I'll take it! The less I have to dig the more time I can lay! Also I hear people talkin alot of good on the newer bobcat excavators the e50 exp. not sure if I would buy one tho...welll.. I'll be honest if the price is right ill buy anything that comes my way!!

Re: Best Size Mini Excavator For Water/sewer Tie Ins


With your trailer weight, I suspect your needing a machine around 8k...
Not sure of your price range, but for about 20k you can get a decent/recent Bobcat. My 331 can get it done (weighs in at 7.5k - cab). I like the ability to haul it around with my Dodge 2500 v10.
Although panned as a sloppy machine (bushings), you can flog it and it hums along. I do like the large Kubota engine (bigger than necessary) sitting in the back.
