New Tires Solved Compaction Problem
A row of corn or beans is planted directly into the center of each rear tractor tire track, but I couldn’t detect any emergence issues with either crop. I used a penetrometer to check the compaction 2 in. from the center of the planted rows behind the new tires. The reading was about 10 to 15 percent less than what I had when planting between the dual wheels.
The new tires raised the tractor profile about 4 in., so I had to adjust the planter hitch to make it level. The tractor weighed 22,450 lbs. with the LSW’s installed, with 65 percent of the weight on the rears and 35 percent on the fronts. Air pressure was set at 9 lbs. for all 4 tires.
Driving with the super-sized tires is easy and the guidance system had no problem maintaining perfectly straight rows. The tire lugs are 2.2 inches high on the rears and 2.44 inches high on the fronts, so there’s plenty of traction. I also noticed that the ride was smoother at road speed and there wasn’t any tire hop.
The 4 new LSW tires cost about the same as 4 sets of duals. That cost included custom color-matched rims to fit the tractor’s bolt patterns and installation by the local dealer. The used tires and rims were traded in as part of the deal.
