When I bought my 5155, it had the FEL and Bucket attached. I then purchased the Mahindra branded grapple, and Mahindra branded box blade, both Standard Duty. I was also going to purchase the Mahindra branded rotary cutter, but we had not yet moved onto our propery. So, we decided to wait until the rotary cutter was needed.
Fast forward, now we've been on our property for 8 months, new house, and the NEED for a rotary cutter was evident. The Mahindra branded cutter was $3,700 at the dealer, and I chose the County Line brand from Tractor Supply. I got it without sales tax (SCATE) and had a 10% discount code. So, I was able to get the 6' County Line cutter for $1,800 out the door.
Granted, the Mahindra branded cutter is made by Kodiak, and is a MUCH more heavy duty cutter. The County Line / TSC is a 200 series rotary cutter made by Tarter.
Will the County Line hold up? Honesty, we shall see. The County Line has a 45 hp gear box, with a sheer pin set up on the PTO shaft. I've already sheered one bolt, and it worked as designed. So far, cutting with it, has been great.
As for 540 / 540E... I'm just learning about this. I was using it incorrectly, and now I know. This weekend, I have about 4 hours of cutting to finish, and I will try both settings. As it was, I was running the PTO shift lever in the lower position (down), and running the engine RPMs around 1800-2000. Now I know, when in 540, I should keep the engine RPMs at 2300... but in 540E, I should keep the engine RPMs at 1750.
I have front / rear chain guards ordered from Tarter... the chain guards are designed for their 300 series cutter, but will work on the 200 series.
Looking back, I wish I had bought the Mahindra branded Kodiak cutter. It has a 7ga top deck, and an 85 hp gear box with slip clutch. But, it would have been $2,000 more than what I paid for the County Line.
I can buy a lot of sheer pins for $2k!
Cheers!
