Been reading through the threads in here and it seems universally people say use a disc harrow. Why would you not want to use a rototiller?

Two reasons:
A disc is cheaper
and
without caution, a tiller can over-pulverize soil, destroying the soil.

JMHO,,,

I'll take the rotatiller any day.

Of course farm sized is another matter.

Rototilling is for row crops and vegetable gardens.
Disc tilling is for field crops, food plots, etc.

Rototilling requires a tractor that can maintain ground speed around 1/2 mile per hour for effective tillage . Tractors with hydrostatic transmissions are great for this work. Gear tractors not so much unless they have transmissions that are optimized for slow ground speed.

If you overwork the soil by excessive rototilling, you destroy the soil microstructure and reduce its water absorption capacity and retention ability. Eventually you end up with impervious clay and then you have to start adding soil amendments to restore the microstructure.

Good luck

That makes a lot of sense. Thanks for the replies.

I have a 5' tiller and no disc harrow. I'd be putting in small food plots, the biggest maybe 100' x 30'.

I should be good to just leave the back flap all the way up and do a rough till?

Tiller with small tractors is the best bet IMHO.Disc with large areas and large tractors are more effective for that type of work.I till up to 10 acres a year;one pass and done with a disc it would be multiple passes to have the same effect.

Most game food plot mixes are strong germinators. Till enough so the food plot seeds have a good probability of germinating and becoming sufficiently established before natural vegetation returns.

Rolling in food plot seed with a Cultipacker or roller will improve germination rate considerably.

Your PTO powered roto-tiller is optimum for soil preparation. One pass should be sufficient. Deer seed mixes contain strong germinators. You do not need a perfectly smooth seed bed. Do not roto-till the fertilizer too deep, 2" is deep enough. You want rain to carry nutrients to the root zone, not deeper. Clover has shallow roots.

If the Pure Attraction seed blend has small seed such as Clover, do not drag. Small seeds require light to germinate. If you cover small seeds with a drag, they will not germinate. Dragging is for medium and large seeds. If you want to drag for smoothness and for some tractor seat time, drag after tilling but before seeding.

Seed only when soil is moist or rain is forecast several days in succession.

After sowing seed, roll seeds in if possible. The optimum implement is a heavy Cultipacker, which flattens clods, rolls in seed and presses a pattern into the soil which directs moisture to the seeds and may aid in erosion prevention.

Used Cultipackers are $400-$600. A Cultipacker consists of heavy cast iron wheels on an axle, supported by a frame.

You can buy a cheap poly roller from TSC or another farm/tractor supply store which will last several years, if you empty water before hard freezes. I have used the poly roller in Photo #4 for six years. ((No hard freezes in my part of Florida.))

Or you can press in seed with tractor tires, which will take time over 1.5 acres.

Then, pray for rain, like agriculturalists for 7,000 years. If the soil drys out you will gradually lose some of the seed, which is vulnerable after germinating.


It may take you several years to conquer the residual weed seeds in recovered ground. You can use 2,4-D herbicide ("Kills broadleaf weeds, not grass") in a one gallon, poly tank hand-sprayer to control the largest weeds which sprout amidst your food plot seed. Buy 2,4-D concentrate in the ag chemicals section at TSC or whatever your local farm/tractor store is. Deer will browse many, not all, weeds at some stage of weed growth. The objective is to prevent undesirable vegetation from producing seed.


Disc Harrows and PTO powered roto-tillers are both soil mixing implements which accomplish soil mixing in different ways.

Don't forget rocks a discount handles them better

A disc isn't intended to be used as a primary cultivation tool. If you turn the ground over with a plow let it sit through the winter then disc it in the spring to break up the clods and smooth the surface you will kill off most of what is growing now and have fewer weed problems to deal with. This is how it was done before herbicides became popular.

A tiller is a one pass tillage tool, but it will leave a lot of weed seeds near the surface and herbicides will likely be needed to deal with them.

Both tillage methods can create soil problems. It's up to you which to use.

Good luck
