Not all manufacturers use DPF. Mahindra, as an example, uses MCRD technology, but does use an EGR instead. This goes all the way up to 75 hp on all their tractors. Their tech is less problematic when repair/replacements is necessary.
Within 5 years of ownership, my Mahindra has never had this problem. The RPM’s do need to be @ 1500-2000 depending on activity, and is designed to operate safely in that zone. Less down-time dealing with complicated emissions controls.
My Kubota does a regeneration lasting 10-15 minutes every 50-75 hours of use. Nothing to get too worked up about.
I just put a deposit on a Mahindra 4540. The MCRD is one of the things that attract me to it.
Same here. Right when getting to the barn the light comes on . It takes longer than 15 min for our 90 hp JD and don't dare have any air restriction or it can run hot during regeneration. Also don't cut off the engine until it finishes. We've spent almost $2000 in DPF repair. If you reeve it up it does cut down on the time.
Yea but a 25hp truck ain't gonna cut it.
Interesting, on my John Deere, the RPM locks at 1,500 for 15-20 minutes during regen. Can't manually throttle it down.
Same with my 4044m if i don't run at 1500 plus enough.
I have a 2019 Kubota M70/60 equipped with DPF. The regen light would come on every 10-12 hrs of operation. If mowing or baling, no problem because you have the revs up for a prolonged period and you can keep working interrupted with no issues. However, that pesky light can come on just when you are ready to put the tractor away or are doing low rev operations like loading. Then you may have to sideline the tractor, put the revs up and wait. Last year I was buying antigel for my tractors and grabbed what I thought was two qt bottles of Lucas antigel when one was actually Lucas injector cleaner and upper cyl lube. Rather than return it I added the cleaner to my fuel. Twenty hrs later the regen light had not come on leading me to think it broke. I've been using this product since last November and it has doubled the time in between regen cycles. You might want to give it a try.
If it hae a particulate filter but just runs higher emmisions temps, thats the way to go if you want/ need higher horsepower.
Wow. Your 7100 looks just like mine except mine says B7001 as it started in Vietnam as a rice paddy tractor with a roto tiller on the back. A Asian guy imported them to Canada where he mounted a FEL which looks exactly like yours and then when i retired i hauled it down to Panama where it lives a pretty easy life now on my 5 acres. Been looking lately as i needed more fuel filters and having trouble finding the original size that slips into the filter housing. PS mine could use paint justclike yours. Guessing mine is likely late 80s maybe early 90s.
I'm not sure I posted a pic but here she is - no big deal to look at as its lived its whole life outside.
