Grass cuttin today.

With the Case 224. Worked great. Gadget specs are, .9 of an hour to do the grass. Hydraulic system oil 122F, out side temperature 62F. 2700 rpm while cutting grass. To bad it doesn’t show volts.
Head lights on because in Canada, you have to have your daytime running lights on, you never know when you’ll meet an on coming garden tractor mower in your own yard. :giggle:

Noel - 2700rpms seems a bit low to cut your lawn. You should be up around 3600rpms. When the rpms get too low, the cutting blades can tear through the grass blades leaving the grass tips stringy. The tips turn yellow and loose more moisture. Same thing that happens with dull blades.

Tractors look great. Do the knobby front tires rip up the lawn?

No troubles with the front tires. Ya I know the rpms should higher. But it works fine like that. I don’t have that great of lawn any way. 1/2 weeds. :giggle:

Saves on gas 👍
I haven't mowed my complete lawn in 3 to 4 weeks. It's been so dry that two weeks ago I mowed about 1/3 that was still green and needed to be cut.

Cut the grass again. Only 20 or so to go. :giggle:
No grass on top of the deck. But grass was sorta dry and was not very long. A little greenery in the grill :giggle: Temp of the drive oil today was 122F. Outside temperature 20C (68F) I think. Left engine running at about 2000 rpm while blowing off the deck and cooler, engine and every thing else. Backed the tractor in garage and drive oil was down to 113 F.

Just finished cutting the grass. Drive oil temperature at the start was 71F. At the end of cutting was 126F. Left it run at 2000 rpm while I blew the very little dirt and grass of it. That was about 10 minutes or so to get hose, blow off the tractor and deck and put the hose back. Backed into the garage and drive oil temperature was 117F. Temperature today was 77F.

Grass was long today.

So not to bad I don’t think. Your thoughts.

Next time I cut with the 4118 I'll try to get a temp for comparison and then the 448. :geek: :letmesee:

@propane1 , can you please remind me where the temperature probe is located?

Picture Eugen. I just put the sensor on the return pipe, wrapped it on some how and put the rubber hose over it.
So it’s sensing the temperature of the pipe, not the oil, but it should be close enough to the right temperature.

I was wondering, because I'm not sure myself how to measure the engine temperature of my 644, same engine as you, the Kohler K321

Just finished cutting the grass with the Case 224. Drive oil temperature at 71F. Outside temperature 72F with a feels like 86F, with the sun out. Drive oil 132F at the end of cutting. And by the time I let it run for a few minutes and blow of a little bit of dirt, temperature is down to 112F. So it seems to be consistent and is working good.

Nice to see consistent temperatures like that, it's a healthy engine. Good for you Noel! :cheers:

I finally got to cut the lawn today, I decided to use the 448 today. I took some temp readings with my heat gun for comparison to Noel's. After 3 hours of mowing wide open throttle.
Outside air temperature 88°f
Engine head bolt 303°f
Oil filter 270°f
Hydraulic oil in tank 170°f
Oil cooler surface temperature 145°f

Next time I'll do the 4118.

88F is up there Tim. Hot compared to mine. But I don’t have the same measuring tool as you. Neat comparison.

It's been warm here Noel, it was pretty hot mowing with the heat blowing back off the engine, but I wanted/had to get it done.

I don't think our temps are to far apart if you compare my cooler temp to yours with the sensor on the line. Factor in the air temp difference and running harder/longer

Mowed with the 4118 today, been kinda curious to see how the oil temps compared to the 448 considering how much more work the hydraulic system is doing.
2 hours mowing fairly light grass
Outside air temperature 80°f
Engine head bolt 298°f
Hydraulic oil tank 185°f
Oil cooler surface 170°f

At the end I mowed for about half an hour in some grass that had not been cut this year, 2' tall tuff stuff, made her work a little. Hydraulic oil tank temp 202°f
