This is where my 78 got stuck it doesn't look to deep but it's wet.
This is my 91 to the rescue .... or not.
Here's what pulled them both out, an Oliver 88.
Here are my sets of tires, the ones under the truck are my worn 50-60% tread 33'sx12.5, set of 4; the next set is my 31'sx15.5 Terra tires 100% tread, set of 4; and the last and final are my 33'sx12.5 with 95% tread, set of 2. The first set I bought for $250 and that was for 8 rims/4 tires. The next set, the Terras were the same price. and the last 2 spares w/95% tread were a junk yard save for only $75
