John Deere 318, Highest Cut Possible?
Posted April 26, 2015 - 04:35 PM
I just picked up a very nice John Deere 318. It is an early 1983 model with a 50" deck. We plan on using this as just a backup mower for the wife to help out with. We currently use a SCAG Wildcat with 61" deck. We now several acres of nice fescue.
I mow very high, for years I mowed at 5" and we have a beautiful thick fescue lawn. The neighbors always comment on it. I recently went to 4-1/2" but don't want to mow any lower than that.
Can this 318 be set up to mow at 4-1/2" high? I really need to get it that high, even if It needs a slight modification? Let me know please.

4-1/2" high? wow. I keep mine at 2-1/2 and if I had to actually "measure" it before cutting, the tallest blotches MIGHT reach 3-1/4 before mowing .
Can you do a lift kit/bigger tires?

I will play around with the 318 and see how high we can get it. I wasn't really looking for a 318 but just stumbled upon it. It was one of those no brainer, stupid good deals that you can't just walk away from.

Not sure on the 318, never had one. I have done this with a few gt/lts. Bigger tires may cause a deck clearance problem. Adding to the gauge wheel / stripe roller brackets is another way. Some units may develop a rub issue from the deck pulleys being too high, so you might have to do a little of both.
Deck leveling isnt quite as critical when mowing high, but you still need to spend some time to get it as close as possible. Raising one corner will sometimes lower the opposite corner, so you may have to chase it around the block 3 or 4 times before you get it dialed in.
I have 4 2x4s cut at 4.5" to sit the blade tips on to get it close, then pull them out and use 1 as gauge to check height while adjusting.
Make sure your tires are all aired up the same too. Use a tire gauge, not just the old kick it and see if they sound about the same. If it has old tires, check for a hump in the center of the tread. Even with the same psi, one could still have that corner setting a little higher
