What model/weight TR3 Rake did you buy? What tractor brand and tractor model do you pull the TR3 with? Did you buy your TR3 Rake new, from ABI? or previously owned?
Works ok on level ground but not well otherwise.
What does this mean? Level as in flat, as opposed to sloped ground?
(or)
Flat, as in smoothed land?
TR3 Rake is not for primary cultivation. Has the land the hogs are rooting up been cultivated in the last twelve months?
I have a Command Series, ABI's heaviest TR3 model and it has been excellent behind my Kubota
L3560, 3,500 pounds bare tractor weight, during my 1-1/2 years of ownership. TR3 Rake is on my Three Point Hitch today. I was using TR3 this morning, with rippers down about 1-1/2", to cultivate Spring grass growth to extinction on two acre firebreak, maintained as bare sand around a burn pit.
I received no instructions either. I bought my TR3 from a builder in New York, who had never severed rake from the delivery pallet. Gleaned enough ideas from studying ABI TR3 videos to start leveling almost immediately but it took me six months to decipher the multiple adjustments and how each adjustment interacts/interferes with other adjustments.
Insert the Top Link pin and Lower Link pins (2) in the
lower holes on the TR3 Rake.
Gross adjustment is then by varying the wheel heights. The higher/more forward the wheels are set, the more the rake will bite, especially the forward rake. You can remove the wheels entirely, if you wish. ((Earliest TR3 Rakes did not come with wheels.))
Relatively fine adjustment is done via lengthening or shortening Top Link. Shorter Top Link puts more pressure on forward rake, which functions somewhat like a Box Blade moldboard and performs the major work of accumulating dirt from high areas. Shorter Top Link simultaneously
lots rear smoothing rake.
Longer Top Link lifts the forward rake and pressures the rear rake, which is the smoother. (Top Link should be adjust longer than neutral, until you feel Top Link actually pushing down on the rear rake.)
Extending the scarifiers in 1" or 2" increments makes the rake squat, then both front and rear rakes move more dirt. Command Series TR3 comes with tractor powered hydraulic scarifiers, which is very convenient.
Every tractor is dimensioned a bit differently, so I will not discuss fine adjustments, which would probably vary on your tractor, with your TR3 Rake model, form mine. But above should get you started.
