Could someone tell me the difference between the speed of a WD-45 3rd gear vs a Farmall M 4th gear.
I have been pulling a kids ride with a M in 4th and we had to replace it with a WD-45. 4th is way to fast so I have been using 3rd gear.
Thank you
 
1st- 2.4mph
2nd- 3.75
3rd- 5.0
4th- 11.25
Standard 12x28 rear wheels. Oversize 13x28 slightly faster.
 
4th on an M is 5.1, 3rd on a wd45 is 5.0 according to tractordata.com. 4th on the WD45 is road gear, like 5th on the M. The M has 4 working gears and the WD45 has 3, but the range of speeds in the working gears is generally somewhat similar between many tractors of that era.

The 3rd gear in the wd45 and 4th gear in M are about the same. The 4th gear in 45 is 11.3 MPH and 5th in an M is 16.4 MPH..
 
I was expecting the topic to be about horsepower instead of road speeds.

I'll tell my story anyway.

Back in the 70's my dad bought a Farmall M with M&W pistons to pull his MF No.3 baler. At the end of the field was a side hill. He thought the M having the rebore kit would pull the baler up the hill. He was wrong. it would run the baler but the baler would not tie knots.The bales would hit the ground and fall a part.

Dad soon bought a wd45. The difference was night and day. The 45 would pull the baler up hill in 3rd and never miss a knot. He sold the M.
 
What gear was he pulling the M in? We farmed with a Farmall M with IH oversize Fire Crater pistons and never lacked any power pulling a baler and wagon behind it baling in hilly fields. We baled in 3rd gear most of time but if windrows were heavy we baled in second and that is plenty fast if loading on wagon behind baler.
 
I use to bale hay and flax straw, for a living, with a square baler. Very curious u say the bales fall apart, from being to loose, or kinda exploded, from being to tight, i never thought low horsepower had a effect on tying, but i can say using a tractor with a live power take off, would be better!!
 
You have to have enough power to pull the baler
and tractor up the hill while maintaining the
proper PTO speed.

The John deere model A dad had would lay down and
die trying to pull the baler up hill thats why he
bought the M.
 
You guys must have bought wore out John Deere A and Farmall M. Like I said baled with M but our first tractor was a 49 John Deere with power power block and it pulled a JD 14T baler with wagon behind it all day up and down hills. We bought the M because we needed another tractor on farm. We did find the M to be smoother power on pto work than A.
 
No, all of dads tractors were rebuilt when he bought them. The allis had a brand new rebuilt head and new short block and was repainted. The M had only one year on the M&W kit. The A came from the John Deere dealer. it sat on the lot for a year before dad bought it. it had been over hauled.
 
A different tractor should not matter as far as tying knot. Why an M would stall out going uphill baling, would indicate too fast of ground speed for the engine speed. Too many or under the false notion that small square balers are to be operated at less than 540 rpm. Those machines are disigned to operate 540, and work best at that range.
