I have driven both tire and track skid steers on lawns and they both tear them up pretty bad. Have you seen the ASV PT30 with turf tracks? It is supposedly easy on lawn and still has the advantages of a compact track loader. I have used my dads Deere CT322 on lawn and it wasn't to bad, you just make wide turns. The tracks on it are similar to the mini excavator tracks and are more turf friendly verses the skid steer with R4 tires. My grandpa's Bobcat skid steer has never failed at destroying lawns on job sites and it doesn't ride very well on rough ground compared to the CT322. What would your budget be around? Used CT322's start at $24,000 and up verses the tire skid steers which start at about $9000-$15000 depending on your location and availability at the time of purchase. One thing that the skid steer will do is it will out lift most compact tractors, i have lifted 4000 pound pallets of stone with the CT322 and 1500 pounds of barn metal with the Bobcat skid steer. Skid Steers offer better hydraulic output verses a compact tractor and are a lot more versatile in tight locations. But you also loose the ability to use 3 point attachments, especially PTO driven ones and hydraulic attachments are far from cheap. Skid Steer loaders have long lasting engines, i have driven a Case 1840 skid steer with 6000+ hours and it still ran like the other 1840 with 2000 hours.
