I have only run TS-14. I see Cat has both engine combos. I am wondering if the single engine units are as productive as twins. I can imagine not having the extra kick of the rear engine. I know I will get good info from you guys.
They are just as productive if the conditions are right, and alot more cost effecient.
Yep 2 engine means twice the fuel, but twins are a hole lot funner
Lots of "depends." Use of single engine or double-barrels depends on soil conditions, distance, grades, weather, ownership or rental costs, transport costs, and losts of other depends. I agree that operating a TS-14 or TS-24 scraper is about as much fun as you can have with your pants on for smaller or difficult jobs, but for serious dirt, the bigger Cat 637's and 651's are a better option. Costs go up for single engine operations too, when you ad the extra fuel and operators a push cat or two requires as well as their own ownership costs.
Yair...I wouldn't have thought you could compare the machines. In most conditions a twin can self load and work unassisted...a single MUST always have some sort of pusher.
Depends on the area. Places like so cal or calgary have the good ground conditions for them but places of edmonton they are pretty useless
