Front Tires for more deck height C160

[ICONN 0]

My installed deck height has always been very low for my field mowing.  The front wheels fit on 3/4 axles.  The wheels are 15 inches in diameter.  Has anyone tried to increase deck height for mowing maybe by putting bigger wheels on?

You can go to larger front tires but keep one thing in mind: you want your mower deck to ride just slightly nose down. This provides relief from drag that would occur if the rear of the cutting disc is cutting as well. Without that relief, the deck will bog down and cut quality will suffer. 

 

Point being- if you raise the front of the tractor you want to raise the back as well. Many of us have raised frame height by going with larger tires front and rear. But- Because Wheel Horse decks ride independently of the frame, you also have to raise the size of your guage wheels on the deck. This affects all of the adjustments on the deck. It can become frustrating trying to make all those changes actually work. 

 

Standard front tires on 8 inch front rims regularly use 16x6.50-8 tires. Depending on wheel width, you can install 18x7x8 fronts but it makes very little if any difference unless the deck wheels increase in size as well. 

 

My 523-H has 9 inch tall front tires and 25 inch tall rears. Frame height is increased by about and inch and a half. But an unmodified deck on this machine has the same cut height as any other WH tractor. I modified an Exmark zero turn deck for higher cutting, but even then 3.5 to 4 inch cut height is about the best I could manage. 

 

This subject has come up many times over the years. Wheel Horse decks were just never designed to cut much over about 3 inches max, if that high. You may have to cut with the deck fully raised in the traverse position on the first pass and cut again with it lowered. 

 

Or purchase a towed brush cutter for your pasture...
