I think tire condition will mean more than gut hp. Learning from the "sand dune" folks, sand likes fat tires with minimum tread. Thin tires and "tready" tires sink and dig a hole. For that reason I think a utility type tractor like the utility Ford with the 14.6x30 tires on the rear would work Ford Series: 600, 800, 2000,3000,4000. Might even use the 13.6x28. These are low to the ground, easy on/off, very stable, very reliable tractors; gas or diesel. The Red tractors are being used probably cause they cost about half what the Ford does. Most are row crop types with the only one I know of being utility is the 300U. Hence they are high riding with thin tires. Then reverse the front rims and put "take off" current pickup tires like a P245xR16 on the front. Power steering might help with these fat tires in soft material. You have to reverse the front rims as 600x16 is about all you can get normally without the tire rubbing on the steering spindle. Rear tires shouls be "worn out" meaning minimum tread. You want the flotation with just enough lug to keep from slipping. Same way on your boat trailer. Get fat tires. If the fenders get in the way take them off; only time you need them is to stand on while digging for something in the boat, and when running down the highway when it's raining. Good luck. Mark
