need help with discmower

just bought a 7ft newholland discmower for next year looking for a few pointers about getting it adjusted properly and set up tp mow properly it is a hm235
thanks RICK
 
Don't know about that one, but instructions with my vicon said to, mount to tractor with the mower carrage level. Power shaft inline with the mower, and when mowing, keep power shaft level.
 
Level is VERY important for getting a good clean cut. WE NOW KNOW. We will pull it onto a level pad, and measure the front of the blades and the back of the blades. We chained the 3 point so it would not drift down AT ALL. You also have to think if the skids are sinking into the ground any.
 
I've got a HM236. There really isn't much to it. The length of the top link is how you adjust the height of the cut. These are the economy model and very similar to the Fort cutter that it replaced. Keep a regular check on the cutter bar and gearbox oil and keep the belts tight. Replace the knives when needed and it will do a pretty good job.

I almost forgot. Find a level spot to adjust the 3pt height chain. The foot slide by the gearbox should just barely touch the ground.You adjust it by taking up or letting it out a link.
 
Advice I was given about a New Holland disc mower was to run the other way. Everyone around here that had one junked them and went and bought a Kuhn. Says they are much better. But, I am sure there are good and bad in all them. We just bought a new 9' Kuhn too.

Main pointer I have is make sure your tarp is laid back when raising it in the up position or you will rip it and always lock it in position when traveling. Keep good sharp blades on it. Make certain the 3pt doesn't sway and I like to tilt it back just a hair. It helps when battling crawdad mounds.
 
We have an HM235, bought it new, ran it 4 seasons now. I went through the same thing you are going to go through, new mower, never ran it!

It has been a great mower...cuts everything we want, including mature timothy/clover over top of the rear tires...no major issues. They are the "econo" mower, but we only have a small farm, I cut 90 acres a year so it was expensive enough, was less than comparable Kuhn.
 
....main thing is keep your stay chain set and 3pt level when the mower is on working position. Angle top link to allow knives to be level or slightly down. Height chain must allow show to ride barely on the ground or too much weight goes on the bar on rough terrain and it kicks back

Run the remote in neutral, book says float for HM234 and HM235, but that allows too much weight to go on the end of the bar and you will hate it kicking back when it hits a rough spot. I manually raise and lower the bar as needed

Keep PTO rpm at 540 and all times, I can mow 5.2 MPH, doesn't strain 42 PTO HP tractor at all. Only lift bar with remote, and only on left turns, you can leave it down on right hand turns.
