That is fantastic! What a great family memory and I really like hearing about the engine change. I wish I had your talents!

Way to go DOC and Fam!

I saw the picture on Facebook. You did a great job fitting the 433 in the 175 chassis. I love the work you do - it does not look hacked together! You take pride in your work.

If you run the WD-45 and the One-Seventy side-by-side down the road the WD-45 is just a tick faster with 14.9 x 28 rear tires. The One-Seventy has 15.5 x 38's and both engines are screaming at 2200 RPM. Actual speed is 17.0 to 17.3 MPH. The 175 is the slowest because it has 16.9 x 28 tires and 175's are equipped with 180/185 final drives for strength, but are 10% slower geared. I'd say it runs 16.5 MPH at 2500 RPM's as a guess.

This high speed isn't to be used in the field !! It is only when I need extra ground speed to keep up with Farmall "M"s on a tractor ride. When I built the engine, I had the rotating assembly balanced. I also had a small groove ground into the very center of each main bearing journal to see to it the rod bearings would be getting oil 100% of the time instead of 1/3 of each revolution of the crankshaft. A D-17 governor spring is all it took to get the extra speed from 1,700 RPM to over 2,000 RPM. A WD is not much  different when it comes to the oiling system. I'd sure like it to have good oil pressure on the gauge before doing something like that. I know someone (an old deceased customer) who told me he used a D-17 governor spring on his WD with M&W pistons (60+ yrs ago) and the engine lasted one spring plowing season. The failure you ask ?? a rod bearing, from the lack of oiling that the 1/3 crank rotation gave to the rod bearings at 2000 RPM under a load.

The old rule of thumb might be OK for some engines but not for these.

You've tried an AGCO dealership 70229519 is the p/n???  I'd say the top one might be to a D-17.

Yesterday got in 48 miles on a local tractor ride. Had 34 total participants. We took my WD-45, One-Seventy high deck and the 175XTD. Thanks to Kenny L. and my son Matt for a nice ride.

Dr. it was my pleasure to be able to run the 175XTD and what great running tractor and just love cracking the throttle and seeing the smoke roll (sometime I'm like a little kid). As with any of your project you done a FANTASTIC job on the old girl.
