If the blade bolts on your RHINO Lawn Mower are working loose, ensure the bolts are tightened to 300 ft./lbs. If the bolt hole is elongated or oversized, replace the blade carrier. A worn-out locknut can also cause this issue, so replace the locknut.
Why is my RHINO Lawn Mower cutting unevenly?
An uneven cut on your RHINO Lawn Mower can occur for several reasons. It could be due to excessive ground speed, so try reducing it. Worn, dull, or bent blades can also be the culprit, in which case you should replace them. Ensure the mower is level from side to side; if not, adjust it. Improper height adjustment can also lead to this issue, so adjust the mower height accordingly. Check your tractor tire pressure on both sides and adjust if one side is low. Avoid turning too fast and reduce ground speed when turning. If tractor tires are pushing the grass down, adjust your tractor wheel spacing. Finally, a damaged mower pan could be the cause, so repair or replace it as necessary.
What to do if the shear pin keeps shearing on my RHINO 172?
If the shear pin on your RHINO Lawn Mower keeps shearing, there are several potential causes. Ensure the tractor PTO is running at 540 RPM. If you're cutting heavy material, reduce ground speed. It's crucial to only use the recommended shear pin for replacement. Avoid engaging the PTO at high engine RPM; instead, idle the engine when engaging the PTO. If cutting in rocky conditions, increase the cutting height. Also, check the gearbox ratios to ensure the blade carrier RPM is not too high.
Why is the gearbox on my RHINO 172 Lawn Mower overheating?
If the gearbox on your RHINO Lawn Mower is overheating, check the lubricant level and fill to the level plug if it's low. Using the wrong type of lubricant can also cause overheating, so replace it with the proper lubricant. Excessive trash build-up around the gearbox can restrict cooling, so remove any debris.
Why is the gearbox leaking on my RHINO Lawn Mower?
A leaking gearbox on your RHINO Lawn Mower can stem from several issues. A damaged oil seal is a common cause, so replace the seal. A bent shaft can also lead to leaks, in which case you should replace both the oil seal and the shaft. If the oil seal race is rough, replace the shaft or repair the race. Ensure the oil seal is installed correctly; if not, replace it. If the oil seal isn't sealing in the housing, replace the seal or use a sealant on the O.D. of the seal. An oil level that's too high can also cause leaks, so drain the oil to the proper level. Check for a damaged gasket and replace it if necessary. Loose bolts can also cause leaks, so tighten them. Finally, a sand hole in the casting may be the culprit, requiring replacement of the castings or gearbox.
Why is my RHINO 172 leaving uncut material?
If your RHINO Lawn Mower is leaving uncut material, it could be due to excessive ground speed, so reduce it. Ensure you are using full PTO speed. Also, check that the blades are installed correctly for the direction of cut.
What causes streaking conditions when using my RHINO 172 Lawn Mower?
Streaking while using your RHINO Lawn Mower can occur if conditions are too wet for cutting, so allow the grass to dry before cutting. Streaking can also be caused by slow blades unable to cut that part of ground speed of tractor but keep grass pressed down by path of tractor tires, lowering the cutting height may help. Dull blades can also cause streaking, so sharpen or replace the blades. Finally, check if the height of the cutter is lower at the rear or front.
Why is the gearbox on my RHINO Lawn Mower noisy?
A noisy gearbox in your RHINO Lawn Mower could be due to several factors. First, check the lubricant level. If the gears are rough, run them in or change them. Finally, a worn bearing can cause noise, so replace the bearing.
How to improve shredding with my RHINO 172 Lawn Mower?
If your RHINO Lawn Mower is not shredding properly, raising the front of the mower relative to the rear to hold and circulate material longer might help. Also, lowering the cutting height could improve shredding.
What to do about windrowing material with my RHINO 172 Lawn Mower?
To address windrowing of heavy and lush material with your RHINO Lawn Mower, raise the front of the mower relative to the rear.
