If you were going to be digging alot of pools, both fiberglass and gunite, what size excavator would you buy?

Just curious.

id say a 12 ton would be plenty for pools, maybe even something with zero tail swing for tight areas

Cat 5090. Why take more than one scoop?

You could get away with a 5 ton machine if you're not doing deep pools, but a 7 ton would be nice and a 12 ton would be ideal.

Mostly i will only be digging fiberglass pools and most are only 6 ft deep.

You could do it with a 5 ton pretty easy.

I guess a CAT 304 or 305 should work good.

One thing to consider probably most pools will be in peoples back yard you might want to stick with a 161 Kubota sized machine it weighs 11,000lbs.

The only time I can see you running into problems with a smaller machine is if you run into large rocks. You might want to consider a machine with plumbing for a breaker and you may end up buying a small hoe pack.

I would agree that you might want to stick with something in the 10-12 K range with zero tail if not zero swing as well. Tight areas would most likely be the norm. I would see no need to get anything larger. A 30X40X6 is only 266 yards of material. That is an easy day for a machine of that size and you can still move it around with a 3/4 to 1 ton pickup. I would also recommend that the machine be plumbed for aux. hyd. in case you needed a breaker or hoe pac or thumb.

AHH my cat dealer has a mint 2005 305cr with 224hrs with full cab, and aux hy for 45k.... That seems like a smoking deal..
Unless someone made a typo on the website!!
Don't know if i want another payment going into winter though!!!

Maybe just rent it until winter sets in and give it back. Perhaps try to make a deal that it would be puchased in the Spring with a percentage of the rent you paid applied to the purchase price or do a no payments deal until Spring. I am usually not a fan of such things because you end up paying more every month to make up for the nonpayments up front. However, it may make it more easy to digest.

On the Bobcat line the 337 or 341 in conv. tail and I believe the 435 is the larger of the zero tail machines

30% of my current business is pools. Standard size here is 20'x40'. Soil conditions vary from rocky to fantastic top soil. Having a machine that is plumbed is a good idea. I use a 36" modified bucket with a butterblade. My machine is about 18,000 lbs and I occasionally wish I had a smaller machine that could be moved by anything other than a dump truck. ZTS would be ok, but if I was to choose between an off-set machine or ZTS, I would personally choose an off-set. Cycle time and volumn moved are again important issues....that is one reason I modified my 36" bucket to carry 50% more material...Heck, anything will do, and I am not sure one machine is more desirable than another.

I would want something that could easily reach and dump into a full size dumptruck, smallest machine for digging pools that i would get would be a kubota 161 size machine. if i ever needed a smaller machine for a place with limited access i would just rent one.

A quick check of their website would suggest either the 337 (11085 lbs) or 341 (11660 lbs.). 435 (10555 lbs.) if you want the ZTS.

Not trying to take this thread off track but just curious what your opinions are on the NH mini-ex's? On paper the specs indicate that they would be real contenders with other top brands (bucket breakout, hyd flow, etc.) yet I never notice them mentioned much on this site........what's the reason? Doing a little window shopping of my own right now for a mini, just having a hard time trying to figure a positive EVA (economic value added) given my part-time availability to put one to work. Just like to hear opinions on the NH brand. Thanks.

The New Holland mini x is the same as the CASE mini ex which is a Kobelco mini ex. The B. series is a real nice machine. I considered a CASE CX47 before buying the Takeuchi. I was not overly impressed. The next year they released the B series and the improvements were obvious. Real nice machine.
