East of Broken Bow | If you go with a 3 point blade, a tail wheel is a must if you want smooth roads. You also will need one heavy enough to cut, which makes the front end on your tractor light. Add to that the side draft that comes when you have the blade at an angle, and you will need a lot of tractor to be able to handle a blade big and heavy enough to do a good job.
The pull grader removes the 'side draft' of the blade on the 3 point trying to steer the tractor around. It also keeps more weight on the tractor front end, which lets you get by with less tractor to be able to do the job. However, it falls under the same umbrella of needing enough weight to cut hard ground. In my opinion, neither the 3 point blade nor the pull grader you pictured is ideal as-is to do the job in hard ground, but the pull grader has a weight box that you can load down, and likely get to work OK. While we're on the subject of pull graders, yes the steerable rear axle is a VERY desirable feature. Without it, you can't really get the blade down in a ditch to clean it out, without driving the tractor in the ditch as well. Going back to the 3 point blade, I see no accomodation for a tail wheel, which IMO is a necessity if you are wanting to form a smooth roadway.
Personally, I have a Rhino rear blade, not sure on the model, but it is 10' wide, and heavy enough that if I just 'drop' it, it will cause a 150 HP tractor to either stall the engine or spin out (depending on what gear you are in at the time). I have yet to bend anything on my tractor 3 point, but there are times I have been concerned, with all that weight hanging so far back, with the side draft of trying to roll a lot of dirt. The pull dozer would not have that concern. | |
