Hi, Folks. Many of you have read my posts about track - and 4 wd - loaders here before. I currently work for a company that has NINE Cat track loaders, 2 hydraulic excavators (trackhoes or whatever else you want to call them) and a Cat D5B 'dozer. All the track loaders have 4-in-1 buckets and rippers. The D5B has a bull tilt blade and rippers. We do many different types of work, by far the greatest part of it being excavating/levelling house sites. We also do driveways, access roads, farm dams and ponds, clearing, clean-ups, spreading and compacting fill, bulk excavations and so on, etc., etc.. Our two excavators, both non-Cat, don't get to see very many house sites at all that a track loader has not previously been too and found rock that the excavators can handle better with their rippers or rock hammers. We trim our house pads to +/- 1/2 to 3/4 of an inch with laser grade checking equipment on the machines. These tolerances are REQUIRED by the builders and concreters. I can tell you from personal experience that it is a LOT easier to achieve with a track loader than with an excavator. I would not personally allow a contractor to use a hydraulic excavator to level a house site for me UNLESS there was rock there that a track loader could not handle. Track loaders beat a trackhoe or a similar sized 'dozer hands down for compaction simply because they carry their heavy, compact frames on narrower tracks than either of the others. Track loaders beat a 'dozer for clearing heavier timber because of their extra reach - unless you have a tree pusher bar on the dozer. Then the 'dozer comes up trumps because of its extra traction. A 4-in-1 bucket on a track loader makes them a lot more useful for clearing operations too. With the 4-in-1 bucket you can, if you so desire, put together a heap of trees and brush with virtually no dirt in it, just as you can with an excavator. And you'll do it quicker with the track loader if you have to move much of it more than about 10 to 12 yards, simply because of the extra travel speed. Also, it is easier/ quicker to get all your trees/logs facing the same way in the heap with a track loader. For dam sinking/pond construction, I would choose a good 'dozer with a straight blade fitted with a tilt cylinder over a similar-sized track loader every time, given that both had rippers. I recently put in a farm dam that was almost 100 yards long by 60 yards wide with a Cat 953 track loader. The Cat D5B would have done it easier. How many times would you have to re-handle the material to get it where you wanted it with an excavator/trackhoe in a dam that size? And you are not even running over your banks with each bucketful to compact them. No, thanks. For mine, if you can handle your material ONCE WITHIN the working radius of a trackhoe and you DON'T have to compact it much, then a trackhoe will likely outproduce a track loader, especially if the going is a little hard. Having said that, I was working a Cat 953B track loader (15 tons) alongside a Cat 350 excavator (around 50 tons) recently. We were digging similar type material and loading it into 6-wheel rigid chassis tippers of around 13 ton payload. The excavator was loading his trucks in three buckets. I was loading mine in 3 1/2 buckets, taking around 30 seconds longer per truck. I'll leave it to your imagination to figure out initial purchase prices, running costs, etc.. Personally, I think the 953 showed up pretty well this time. AND it's a LOT easier to transport around too. Please, don't get me wrong. There are jobs that an excavator or a 'dozer will do better than a track loader and for those, given the choice, I would take an excavator or a 'dozer as it was appropriate. However, if I had to choose ONE machine to be a jack-of-all-trades, it would be a track loader with a 4-in-1 bucket and rippers. As has been said here before, there is nothing much that a track loader will do that something else will not do better. Track loaders are not BEST at much of anything -- EXCEPT VERSATILITY. They will do far more jobs adequately than any other machine I know of. Another 'having said that': If the going was relatively lighter, I would also be considering a 4 wd articulated front end loader with a 4-in-1 bucket and rippers. There are not a lot of these animals around but I have been lucky enough to have operated two for lengthy periods, a Case W7E and a Cat 950. They surprised the h**l out of a LOT of people. Including clearing trees, excavating rippable rock and digging straight out of a face with the bucket. Naturally enough, the Cat 950 beat the Case W7E every which way because it is around twice the size, but it beat it by a fair bit more than twice the production too. Hope this helps some of you who don't have the backside-on-seat time to gather this kind of knowledge for yourselves. You all have a wonderful day. Best wishes. Deas Plant.
