750 Drill Conversion Hitch
Since its introduction at the National Farm Machinery Show in Louisville, Ky., last year, the "Terra Tach" conversion hitch has been used by 750 drills in the U.S. and Canada. The hitch received high praise from Indiana and Ohio farmers during last spring's wet conditions.Two versions of the hitch are avail-able. The dolly-wheel hitch allows the removal of the dolly wheels but works well with the wheels left in place. The hitch lets you transfer some or all of the drill's tongue weight to the draft links of the tractor. The dolly-wheel conversion doesn't add length to the drill's tongue. It takes weight off the dolly wheels and keeps them from causing ruts and compaction on soft ground. It attaches to the drill by removing three bolts on the back of the hitch sliding the U-shaped bracket over the face of the dolly wheel pedestal, then rebolting it.
The drawbar-style drills can also be converted to 2-point attachment with the regular hitch conversion. Both hitches allow much better traction control and turning ability as well as greater clearance for duals and markers. This hitch adds about 18 in. to the tongue length.
One farmer, who formerly pulled his 20-ft. dolly-wheel drill through wet fields with his Cat Challenger, was able to use his tractor and the Terra Tach instead. The hitch has also been used on double box drills.
The Terra Tach hitches are currently being manufactured and distributed by Maurer Mfg., Inc., 1300 38th Ave. West, Spencer, Iowa 51301 (ph 712 262-2992;
